DSL Prob.s

[Game_face]

Ok, Ive looked thru the forums, and have tweak with my stuff a little ( I was scared), and with results!, but not for other applications.

SpeedGuide.net TCP/IP Analyzer
TCP properties for IP = xxxxxxxxxx ()
Browser/OS = Mozilla/4.0 (compatible; MSIE 5.5; Windows 98; Win 9x 4.90)

MTU = 1500
MTU is fully optimized for broadband.

MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.

Default Receive Window (RWIN) = 8192
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 8192
For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
513920 (MSS x 44 * scale factor of 8)
256960 (MSS x 44 * scale factor of 4)

Your RcvWindow limits you to: 131.072 kbps (16.384 KBytes/s) @ 500ms
Consider increasing your RWIN value to optimize TCP/IP for broadband.

MTU Discovery (RFC1191) = ON

I own a HP Pavillion w/ AMD athlon 900, 128 ram, new video card ati 8500 le (comes w/ counter-strike), DSL connection, http://www.go-ctt.com/ homepage for isp, they are called CTT central texas tech(They actually refered me to this site). And they offer 1.5mb d/l and u/l.
And from the last TCP/IP analyiser, my ISP is ok, right?!?!? (meaning THEY aren't slowing me down, right?!??!)

So i figured it was something with my end.

Let me explain that d/l from Kazaa or websites is ok, but when I play counter-strike or day of defeat, or JK2 or WC3 I lag WAY lag, and it makes everyone else on the server lag, im told. People always want me to leave, i do only because the lag is soO bad. On the Half-life mods, net_graph 1 shows that the ping jumps madly; I goes from 90 to 500, or 100 to 1000, and when it goes past 200 its totaly unplayable. I had cable at another house before August, Counter-Strike played fine then. Does dsl just *ahem* SUCK, for on-line gaming?

I don't have a dedicated DSL line or anything so i'm suspecting that? Plz help I've been trying to fix this with them since August, but they're like "We'll call/e-mail you." Now they say that they are working on a problem in the dsl.


Any way Thanks for your help, and support thru fourms.:D

OK Game_face first you need to get rid of KaZaA it is FULL of spyware and will ruin your internet connection. First install the vtcp 386 patch (http://www.speedguide.net/files/vtcp386/236926USA8.EXE) and the NDIS update (http://dslnuts.com/patch/243199us8.exe) then download CableNut and use the following settings:

BcastNameQueryCount - 1
BcastQueryTimeout - 100
BSDUrgent - 1
CacheTimeout - 600000
DefaultRecvWindow - 64240
DefaultTTL - 64
EnableDNS - 0
GlobalMaxTcpWindoSize - 64240
KeepAliveInterval - 500
KeepAliveTime - 14400000
Lanabase - 0
LocalCopyMade - 1
MaxConnections - 64
MaxConnectRetries - 5
MaxDataRetries - 64
NameTableSize - 255
NameSrvQueryTimeout - 100
PMTUBlackHoleDetect - 0
PMTUDiscovery - 1
RoutingBufSize - 146432
RoutingPackets - 100
SackOpts - 1
SessionKeepAlive - 7200
SessionTableSize - 255
Size/Small/Medium/Large - 3
Tcp1323Opts - 0
TcpTimedWaitDelay - 30
MaxDupAcks - 2
DefaultTOS - 92
IGMPLevel - 2
MaxConnectionsPer1_0Server - 20
MaxConnectionsPerServer - 10

Also do the following:

1. Open IE and select tools - internet options - connections - LAN settings, make sure NOTHING there is checked.

2. Make sure you have the latest drivers for your NIC from the manufacturer. Set your NIC duplex mode to 10mb half duplex for Cable, for DSL it is ISP dependent unless you are using a router, if so then set it to 100mb full duplex for both Cable & DSL (the instructions are in my Help & Tips link (http://forums.speedguide.net/showthread.php?s=&postid=643301#post643301)). If you are using a router make sure you have the latest firmware.

3. Clear your temporary internet files.

4. Power cycle your modem, unplug it for atleast 15 seconds.

5. Download and update then do a scan with SpyBot (http://beam.to/spybotsd), anything checked in red is spyware and safe to remove.

:) :D

Counter-Strike is still unplayable, the ping DOES get low(50-100), but it sure don't stay there, i'd say the average is between 200-500, and i can understand occasional lag, but this just don't stop, people hop skip and jump across my screen, looks like teleportation.

Cable played CS fine! Why is Dsl so difficult? I think im going to set a dedicated line, and do some drilling.

Uh, if you got any more suggestions, thanks.

[Game_face]

ONE MORE THING!

I have a dsl filter between the phone jack and the dsl modem, is that correct?

Also, my modem takes about 15min to sync back up after I power cycle it, is that normal?

As for drilling a new line, well Popps won't let me damage the new house. He says I don't know what im doing, I WORKED AT FREAKING RADIO SHACK for almost 2yrs. dam it. o well....:o

no, no, no,,, get the filter out of there,,, the filters are only for the phones.:D

[Game_face]

HEY, Thanx Black Sword.

Does this mean I don't need a dedicated line for my dsl?:D

And then I would only need filters for EVER phone tho?

[chpalmer]

This link gives a way to just use one filter for the whole house while keeping your modem on the other side of the filter.
Only attempt if you are familar with wiring or have a techie friend do it if you decide to. http://dslnuts.com/DSLwiring.shtml
