View Full Version : Ping
I have a problem maybe you guys can help me with. I just build myself a new computer and during gaming i am having big ping spikes from 100ms to about 3000ms. It sort of jumps up and down making it impossible to play. I never had this problem before, I know it is not my isp becuse when I trace route the ping is good I know its not the game server couse i am the only one experiencing this problem. What could it be???

what kind of connection do you have??
happen anytime of day or night,
or only certain times?
you may need to adjust your packet
size, a little trial and error may yield
an acceptable ping
I have a DSL connection.
The weird part is I can only see the ping jumps in the game (Tactical Ops) the more activity i do in the game the higher the ping jumps, and then it comes back down and jumps up again. I don't know maybe its the game, although I never experienced it before. Any of you guys know of some monitoring software that can monitor my ping thoughout the day so I can see if it is stable or constantly jumping.

Meaning your MTU and your TTL may need to be reduced. Run DrTCP and try lowering those values in /2 increments.

Where do i get DrTCP? Could it be the game is causing the problem couse I do not see high ping anywhere only when i play

Ok. That makes sense. Try finding a patch for your game. If not, try downloading DrTCP here (ftp://ftp.omarnyc.com/software/drtcp019.exe).
ok i downloaded this software
whats next?
what numbers should I put in those empty fields?

I would leave everything as default except for Tcp Receive Window and TTL. Start with a Tcp Receive Window of 64240 and work your way up in * 2 increments. So the next value after 64240 would be 128480 (64240 * 2 = 128480). You also want to start with a TTL value of 254 and work your way down to around 30. You don't want a very low TTL value though. TTL packets that expire to this standard will create more packet loss than it will improve packet transmit performance. You would get a lot of packet loss using a TTL of 30 if the network that connects your Internet line isn't very responsive, or if it doesn't route very well. I'd recommend a TTL anywhere between 254 and 75.
Ok, Thanx I'll give it a try when i come home.

You're welcome.
BTW will this patch do the trick?
sguide_tweak_2k.zip (updated 12/18/01) - Generic patch for Windows XP and Windows 2000 (all versions). This patch will optimize your TCP/IP Registry settings for high speed Internet connections. To install, extract, then just double-click and reboot.

It's probably the same thing as I recommended you do with DrTCP. Try that tweak first if you want. I may have missed a param or two.
MosDef112,
I did everything you said but the games are still laggy. The intresting thing is I have pinged myself for 5 min and on the average my ping is pretty good, I wish I could show the picture but I have no clue on how to post it. I am out of ideas i have no clue y my game is a nightmare
Now I have also pinged the game server and return an average ping of about 45ms which is pretty good.
That leaves only the game that could be causing the problem or maybe it has to do with video card and network card.
MosDef112
01-04-02, 01:46 AM
Nah, it's not your hardware. We both own the same KT266 motherboard, although my manufacturer is Gigabyte. That motherboard really makes good use of resources, even if there's a card or two that aren't playing nice.
Since you do get fairly good pings to the game server, that leaves the game as the questionable culprit to your problems. Try finding out if there's a patch for your game out there that addresses that problem. If not, we can always try and troubleshoot your network routing for an latency issues.
Problem is gone!!!
After sitting the whole night yesterday trying to figure it out I think i fixed it. I did 3 things, not sure which really fixed it.
First after SisSoft Sandra performance check I found out that the pci latency is high. So i went into the bios and set it from 128 to 32.
Second I downgraded my video drivers from beta to Widnows 2k certified release.
Third I upgreaded direct x from 8 to 8.1.
Now I am still not getting the ping I was hoping for or what i had before but it is stable not jumping.
I usto have from 40-90
Now i am getting from 100-180 still playeble.
Thank you MosDef112 for your help and advices.

The Speed Guide optimizer (http://speedguide.net/files/TCPOptimizer.exe) will let you up grade your system.
Download it and run the program. When your in, tell it your connection is DSL and just set everything to optimal settings. To view optimal settings for your connection, just click the little option at the bottom. (I am horrible at explaining things)

****, the problem is not gone!!!
But atleast I have some idea where it is coming from. I didn't realize that my brother was gone for few days so his computer was inactive. Now he is back and he is playing is game AOK which does not depend on ping and i have ping over 1000 again. I don't understand we usto be able to play together at the same time without problems when i had Win98 installed. It is becoming a nightmare now.
Would my only option be to take turns? or there is something else i can do?
Thanx
I am thinking would it help if i put my computer in DMZ mode on the router? The wierd thing is I still ping servers like yahoo.com for 10min and get an average ping of 45ms. I am clueless on is happening, I would appriciate any suggestions.
Thank You
Alex
no luck with DMZ mode!!!
Another pattern i noticed is ping spikes usually occur when I am in action shooting and jumping but when i am killed and in watch mode the ping is stable low.
would replacing my cheap NIC and Router resolve the issue???
I am finding it hard to belive that all of you are clueless as I am. Speak up I feel like I am talking to my self.

1. I don’t have (Tactical Ops) so I may not be able to help
2. Based on the fact that your lag comes when U have 2 rigs on,, then your Router is probably not the best. I have never heard much good about d-link routers.
3. what are your tested Upload and Download rates? example 900kbps down and 120kbps up.
4. if your upload rate is low then that can really hit you; if your brother has morphus or something like that running and your upload bandwidth is saturated your ping will go thru the roof.
5. instead of just pinging the game server try doing a tracert. that will show you the ping times to each HOP. May shed some more light on the subject. example C:\>tracert xxx.xxx.xxx.xxx <--put in IP address, or even c:\>tracert www.speedguide.net
6. lol , had contractor walk into my office and now just going to complete my message and MosDef112 has posted so do that too.

my connection is a Verizon DSL 640/90 which although has pretty much the worse rating has been very stable for me.
The only thing my brother runs is the game called Age of Kings. With him being gone my connection was stable at about 135ms. Now it is spiking when two computers run at the same time even if he is not playing game. But this is not the case when the game is not running the ping is low and stable. Another problem I noticed is that some times my internet activity icon lights sold when there is no activity coming out of my Rig but activity comes from my brother's rig. Which makes me belive that the router is garbage. But then again I never had this problem before when I had windows 98, I have the router for about a year. The first thing what was on my mind is to do tracert to find a verzion gateway with a high ping and go complain with verizon. This was not the case since with tracert i am averaging about 90ms. I am gonna go home and try MosDef112 recommendations and then try a Netgear RT314 I am also thinking it could be a problem with my Nic which uses a cheap realtek chipset but was always stable for me before. My last test would probably be installing the different game and if the ping is good mostlikely the games netcoding is bad so I will have to dump Tactical Ops.

If you had no problems with W98 then possibly something is fishy with XP and your game our one of your files,,, check the net for your game to see if there are any XP updates/fixes for it.

I use 2k and there are nothing on this issue no updates.
I just disconnected my brother from a network for a few hours and was getting ping from 68-215 which is playable.
By the way is there a way to reset Netgear RT314 withought serial cable but through ethernet?

Yes. Just got into it via telnet using your router's LAN IP address via one of the LAN ports of your router. Telnet is disabled by default via the WAN.

Thats the problem, I need to reset it because i don't know the IP of the router it was setup for my work, and the defauld 192.168.0.1 doesn't work.

Just some thoughts, dealing with various areas.
Although I don't play the game you're dealing with, I've been huge into online and LAN gaming for a long time. You mentioned changing video drivers helped lower you ping a bit, and you also mentioned that your ping spikes when things are very busy in your game. Here's a fact about some online games, which became pretty well known back when Quake 2 was king. Your max frames per second have a huge impact on your ping. This is also tied together with the rate in your game. Quake 2 had been out for a while, when video cards were really taking off performance wise. People who upgraded their S3, Rendition, or Voodoo1 cards, to new TNT and dual Voodoo2 SLI setups, discovered that while the game now looked great, and ran at fantastic speeds...their pings were getting horrible. By editing the games autoconfig file and capping the maxfps of the game, their pings were nice and level. You could watch this on the fly using the built in netstat utility that Q2 had. The reasoning behind this...is, depending on the game engine used, some games ask for updates from the server per frame being drawn. You can imagine how high FPS puts an incredible demand to your connection to the server. Perhaps you could do some research on some websites for your game, and look for ways of limiting the FPS on your game.
Rate....most games have at least some method of changing rate, be it via the setup somewhere where you can change connection type from 33.6, 56k, ISDN, Cable/DSL, T-1, LAN, etc. This changes the net rate. Some games let you specify the rate via the drop down console...on the fly. Again, refer to some websites for your game to adjust this, I know this works well with Q2, Q3, and in a different way, UT.
Your hardware....DLink routers are near the bottom of my list. NetGear routers are much better, but they still have some issues with certain games when you host servers, which is why I got rid of mine. For playing games as a client, they work great. Current favorite router for gaming is the Nexland ISB SOHO....the thing is blindingly fast. The DLink shouldn't hammer you much if you're the only person playing through it..granted when others log on and share the router with you, less expensive routers will start to break a sweat because of their basic inexpensive hardware. But stand alone, that shouldn't be your problem.
Your NIC...I prefer Intels and 3COMs. Also, never use the top PCI slot, almost guaranteed to share and IRQ with your AGP video card...neither of which you ever want to share an IRQ. The standard for NIC's is PCI slot #2. I forget which OS you are using, if you specified, but if XP or 2K, this opens up an entire other arguement about ACPI and it's supposedly "ideal IRQ sharing" methods....which we've debated to death over on the hardware forum. I find leaving ACPI on, yet ironing out IRQ's in the BIOS, easily leads to no IRQ sharing, and proven better performance. I find by disabling legacy devices on your computer that you never will use, such as COM1, COM2, and LPT, it frees up 3x IRQ...which the OS can then spread out devices more. Usind RAID? Then disable IDE 1. No USB devices? Then turn off USB ports. This leads to a more stable system, often cures little "hiccups" your rig is having, leaner system, better performance. Latest drivers for your NIC?
Are your network protocols leaned out? Only using TCP/IP? Or if using TCP/IP and NetBEUI, is TCP/IP unbound from networking services?
YeOldeStonecat,
I think you are absolutly right about video card interferience with ping stability. The game that I am playing is called Tactical Ops which is Unreal Tournament Mod. Basically its an special ops type of game like counter strike. When you die you have to wait for you teamates to die so you can watch them in the watch mode. When I am playing the ping is jumping but when i am in the watch mode the ping is low and stable. On the other hand I haven't found any issues about this, and I am sure a lot of gamers use their top notch Geforce3 with the high fps. There is nowhere in the game you can specify max fps but can specify min fps. Rate I set to DSL. Ping spikes are not so bad when my computer is the only one active on the router. But when the second computer goes through the some activity the ping spikes become pretty bad. I never had this problem on my older win98se rig, even when two computers were playing at the same time the ping was low. I updated the firmware for the dlink router and drivers for the network card, that did not help. I am having trouble with the netgear router as it was used and configured at work I don't know what the ip of the router is therefore can't enter the setup. I will try to take a serial cable to do it through telnet but i don't know how much luck will i get. I use win2k and only TCP/IP.

Isn't there a 'reset button' on the Netgear? Hold it in for 5 seconds and resets the router to facotry default?

Hey hey! Don't insult a router that I currently own at home. ;)
If it is infact the routing problem I would probably look forward to getting Nexland ISB SOHO router. And ofcourse a few bad words :D to D-Link costumer service.

Ahhh the UT engine....I'm familiar with that, although forgot a lot. We run a big UT server, www.zombiebattalion.com, which runs 3x UT servers on the same box, as well as some other games. 209.150.0.191.
I ping from 17 - 25 to it! :-)
I'm at work, forget most of the settings, but the unrealtournament.ini file in your game directory, I think in the system subfolder, you can edit a lot for online performance, similar to the older rates.
Visit http://www.planetunrealtournament.com/game/tweaks.shtml
and
http://www.tweak3d.net/tweak/ut/
And don't forget that cachesizemegs setting...change it from 4 to 96 if your system has over 128 megs. Raising it past 96 doesn't do a thing...96 is the sweetspot.

I'm not sure if 2K pro has this option, but I know that all other versions of 2K have it, and I think pro does as well. There is an option that allows you to direct how the CPU uses the memory. Try looking into: ----> System Properties Panel -----> Advanced Tab -----> Performance Options -----> and then select the option to optimize performance for applications instead of background services.
I believe the default selection for any version of 2K is background services and this helped me to alleviate some ping spikes while playing online games. Also if you are playing the game logged onto 2K as the administrator, try creating another user account as a power user so you have all the privileges you need to play any game online, and then use that user account when you are going to play.

I'm almost certain that your problem is due to the amount of upstream bandwidth that game needs to use to synchronize your game session in real time. Your latency shouldn't spike that high during two-file downloads, especially when you're not uploading anything at the same time. Because of ADSL's native inability to sustain downstream and upstream traffic simultaneously, hence asynchronous, every time you interact with players in your game you are essentially forcing your ADSL connection to send and receive data at the same time (your sending the game server your gaming action, like if you want to shoot or move, and the game server returning updated frames reflecting your interaction with other online players). Your ADSL connection may be able to handle a single interactive session depending on how many frames per second your game tries to force to update your online session. After two or more sessions, you will begin to notice the lag. Only best way to resolve your problem is to try and tweak the game like StoneOldecat suggested, or get a DSL circuit from Covad. Their line encoding isn't that much better, but I know it could handle simultaneous downstream and upstream traffic a little better than Verizon's typical sh*tty circuit could. Getting a cable modem may help too, if available to you.

Here is what i did. I took my old k6-III 400mhz, 256mb sdram, voodoo 3000 computer and install win98se on it. After that I installed Tactical Ops (unreal tournament) I placed it on the same network. And i did the test. When my other computer was playing AOK I started playing Tactical Ops. Well the result is the ping never went over 200ms. Also no tweaks were applied. Although the ping was ok, the game was a bit slow on that machine. So what could this mean? Two things I guess either Win2k is antigame os, or some hardware issue.
What do you guys think?
Maybe its not the game... could it be the bandwidth you are suing thats causing the problem. Try pinging from dos (use ping -t) and after a while start to downaload some files. Do your pings degrade significantly when you have a download in progress?

Yes, but read my previous post, I tried playing on my old machine with win98se, while another machine was playing AOK, no ping spikes.

If you have more than one computer sharing a modem, whether by router or ICS, then it is important that you carefully select your RWIN. The RWIN should be not much larger than the calculated value, that is, the round trip time x connection speed converted to bytes.
If it is set to a larger value, then the downstream data is queued up at the CMTS and the packets for the second computer are delayed until the queue is emptied.
Similarly, if one machine is using UDP the same thing can happen regardless of RWIN.

Hi Kip, thanx for the info, but can you please translate it in english and tell me what should I do.
Thanx

If you have a connection that runs at 1 megabit and you wish to connect to a site that has a latency of 200ms, then your RWIN should be 1 megabit times .2 seconds, or 12.5kbytes.
12.5 mbytes x 8 bits/byte = 200kbits, or as much as your modem can transmit in 200 ms.
If another active machine on the modem has its RWIN set to 256kbytes, then there will be (256 - 12.5) x 8 = 1.85 mbits of data en route to you, sitting in the buffers of the Cable Modem Termination System waiting for your modem to catch up. That will take 1.9 seconds to clear out of the buffers. Any data that now arrives at the CMTS bound for your machine will have to wait that long, hence the high pings.
UDP packets, used in some games, aren't regulated by RWIN, so a large amount of UDP traffic can back up at the CMTS even if your RWIN's are set correctly.
That is one of the limitations of sharing a cable modem.
Check the RWIN's on the other machines and reduce them to a value such as 32k.

I installed Windows XP pro to see how that was. Not too good, crashes more often, drivers are not great, and still the same ping spikes. Actually even worse now my brothers computer doesn't have to play for me to experience highs in ping. I believe it has something to do with graphic vs speed. If i stand on one place the ping is good, when i move around it jumps up and down, the graphic becomes too intense for the connection to handle. Whats really funny is that on my old machine i don't experience any problems at all even if two computers are dl my old machine doesn't have any ping spikes. I guess my only option left is to go back to win98se and see if that works. But i am not gonna do that, one game can't make me downgrade my system.
Sorry to bring out my old thread, but I belive finally I fixed the problem for good. I selected my internet speed as dsl in the UT options. By default it sets up netspeed 10000. I found out that UT has an utility built in called stat net. This monitors ping, and packet transfer at real time. Basically to reduce the lag in ping I had to reduce netspeed from 10000 to 4000, and the lag is gone. I think this would mean that my dsl connection even though has a hight bandwidth is only as good as 56k when it comes to sharing gaming between 2 computers.

hi, i only think loud
you have a via kt266 board ??? and a SB Live ?
you told at the beginning something about setting PCI latency
your nic is a PCI card
your SB Life too
and i heard about something like a VIA BUG in connection with the SB Live. I Not want to Blame Creative Labs, its a good Soundcard,
but it makes such heavi PCI Traffic that its possible that it blocks the Sync of your Nic (HINT its PCI).
i heard about a solution integrated into the newest via 4 in one drivers go and get them from WWW.VIAARENA.COM its a strange installation description they tell to first unplug the soundcard then install the drivers and then insert the card again ?? its only a clue im not sure about it
the other idea is you set ADSL speed in the UT settings, try to set ISDN or 56K Modem (this people can play the game too so it should work) because its true you have ADSL speed when you play alone, but whats your speed when the other computer works too ?? so set it lower :-)
hope i could help

thanx, I will install the drivers. I can't find anything about what you said on the SB Live issue though.

hi, here an outtake of the FAQ concerning sound from viaarena.com maybe the heavy pci traffic mentioned there affects your nic too ?? maybe, but knowing about the bug is not bad at all

Question:
I am having trouble with a system using a VIA chipset including a 686b southbridge and a Creative Sound Blaster Live card.
Answer:
When the 686b southbridge was first released, motherboard manufacturers and VIA discovered a problem when trying to transfer files between the primary and the secondary IDE channels on motherboards using ultra-DMA, when a Sound Blaster Live was plugged in and drivers activated. This issue was caused because too much noise is transferred across the PCI bus by the Sound Blaster Live driver set. In an attempt to fix this issue, some motherboard manufacturers modified their BIOS. In some instances, these modifications to the BIOS caused a data corruption error even when not using a Sound Blaster Live. VIA released a patch which resolves this issue, which is incoroporated in the 4in1 drivers from the 4.31 version onwards. Motherboard manufacturers were advised to change the modifications made to thier BIOS to elimate the data corruption issue. If you are experiencing data corruption or lock up when transferring files between two IDE drives: 1) Make sure you have the latest BIOS from your motherboard manufacturer. 2) Make sure you have the latest 4in1 drivers 3) Make sure when you set up your system that you install the 4in1 drivers both before and after you install the SBL to make sure that the drivers see your SBL and install the correct patch. The patch will only install if the SBL is installed

thanx for the info
Windows XP and Halflife doesnt go together get it already.
In order 2 fix ur ping jumps (and probably framming), install latests drivers for ur sound card.
After u do that, open cs -> Configuration (main page) -> Audio.
There u got 4 "possibilities". Put X in the 2d one, and X in the 4th one, and remove the X from the 1st and 3d.
That's the only sulotion i know for XP ping jumps and it almost never disappoints.
Good luck.

OMG I'm sorry to hear about your problem but guess what, I also have this type of problem playing Americas Army (similar sort of game).
Now, I have a 2.2meg line using a Thompson 330 ADSL modem.
Its on a Dell Dimension 8400 (I know its not a great machine)
I don't know why my ping has started jumping around the place like yours, as nothing new has been added to the pc and no upgrades have come through.
My ISP is sending me a new modem as they are at a loss but I don't think this is the issue.
Can anyone give me a summary of what works to sort out this problem?
