Verizon DSL and low speeds

[Zziggy00]

Hello, I've had my Verizon DSL connection for quite some time now and I get about 60 kb/s and that's ok and I can't complain comparred to my previous 56k connection a few years back, but I went to Verizon's website and for my plan i should be getting a max. of:

Up to
768Kbps/
128Kbps

And I've gotten a HIGH of

512Kbps/
81Kbps

I've tried one of the windows XP reg. tweaks and that's what has gotten me to about 60 kb/s download speeds, before i was getting around 50 kb/s

Is there anyway to get me closer to what I'm paying for? Any help would be greatly appreciated. (NOTE: I've read a lot of posts and I will admit i'm very lost when it comes to all the words referring to MTU and Packet Sizes, please be nice :D )

here is some other information:

2002-08-02 13:56:55 EST: 509 / 81
Your download speed : 509540 bps, or 509 kbps.
A 62.1 KB/sec transfer rate.
Your upload speed : 81004 bps, or 81 kbps.

connect using: PPPoE

System: 1.7 Ghz Celeron, 256 DDR Ram, Westell WireSpeed DSL Modem.

Thanks again

You should be concerned less about the MAXIMUM they promise and more about the MINIMUM. Rarely do you get the MAX but you should get better than the MIN. If you are getting greater than the MIN, there's nothing you can do except tweak (info available here at SpeedGuide) or change providers.

Call them to determine what the minimum standards are.

Welcome to SpeedGuide. :) Lots of great information here!

Thank You for responding to my post, and your right I shouldn't be to worried about the max, but it's just so tempting to try and get to it, and even more so when you see the speeds others are getting.

And I would really like to tweak everything possiable before I call tech support at my ISP. I hate them. It all depends on the person you get, one might be tired of listening to the phone all day and give you a crappy or "nothing you can do about it" answer while getting a different person and asking the same question can really make the difference and you can solve all your problems.

So if anyone could help me tweak things up, please do!:)

I've gotten some more info:

MTU = 1480
MTU is optimized for Windows XP PPoE DSL broadband. If not, consider raising MTU to 1500 for optimal throughput.

MSS = 1440
Maximum useful data in each packet = 1440, which equals MSS.
MSS is optimized for Windows XP PPPoE DSL broadband. If not, consider raising MTU to 1500 for maximum throughput.

Default Receive Window (RWIN) = 255552
RWIN Scaling (RFC1323) = 2 bits
Unscaled Receive Window = 63888
For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
506880 (MSS x 44 * scale factor of 8)
253440 (MSS x 44 * scale factor of 4)
126720 (MSS x 44 * scale factor of 2)
63360 (MSS x 44)

bandwidth * delay product:
Your RcvWindow limits you to: 10222.08 kbps (1277.76 KBytes/s) @ 200ms
Your RcvWindow limits you to: 4088.832 kbps (511.104 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 52 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000

The only thing I would suggest is to change your RWIN to one of the numbers indicated by the optimizer.

Some argue that it helps, others say it doesn't, but it won't hurt.

[YARDofSTUF]

ya the rwin value should be a multiple of ur MSS.


try 216000 or 230400

[jim1133]

"And I've gotten a HIGH of

512Kbps/
81Kbps "

Those numbers look like you have not been upgraded to 768/128.

What do you mean??
There never was an upgrade...

With 216000 my results are:

2002-08-02 22:13:35 EST: 498 / 79
Your download speed : 498203 bps, or 498 kbps.
A 60.8 KB/sec transfer rate.
Your upload speed : 79507 bps, or 79 kbps.

Try different settings to see what's best for you. Sometimes bigger numbers in the settings won't get you any faster, sometimes you have to scale down. Just make sure that you're trying the same site at the same time of day and hopefully the server load won't vary much so you can get consistent and accurate feedback.

Keep trying! That's the fun of tweaking: "Let's see if I can get more speed out of this if I change my RWIN to xxxxxxx." :)

Zziggy00 first download Cablenut (http://www.student.ipfw.edu/~gottjl01/files/cablenut408.exe) and try the following settings:

DefaultReceiveWindow = 98304
DefaultSendWindow = 16384
DisableAddressSharing = 1
InitialLargeBufferCount = 100
InitialMediumBufferCount = 240
InitialSmallBufferCount = 320
LargeBufferSize = 81920
MaxFastTransmit = 6400
MediumBufferSize = 15040
PriorityBoost = 0
SmallBufferSize = 1280
TransmitWorker = 32
FastSendDatagramThreshold = 1024
EnableFastRouteLookup = 1
EnablePMTUDiscovery = 1
IgnorePushBitOnReceives = 0
GlobalMaxTcpWindowSize = 18720 or 28800 or 47520
MaxFreeTcbs = 8000
MaxHashTableSize = 16384
MaxNormLookupMemory = 5000000
SackOpts = 1
SynAttackProtect = 1
Tcp1323Opts = 0
TcpLogLevel = 1
MaxDupAcks = 2
TcpMaxHalfOpen = 100
TcpMaxHalfOpenRetried = 80
TcpRecvSegmentSize = 1440
TcpSendSegmentSize = 1440
TcpTimedWaitDelay = 30
TcpUseRFC1122UrgentPointer = 0
TcpWindowSize = 18720 or 28800 or 47520
MaxConnectionsPer1_0Server = 40
MaxConnectionsPerServer = 20
DefaultTTL = 64
DisableUserTOSSetting = 0
TcpMaxDataRetransmissions = 6
DefaultTOSValue = 44

Also copy and paste this and make .reg file and merge into registry.

************begin copy and paste***********
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servi
ces\AFD\Parameters]
"BufferMultiplier"=dword:00000400

************end copy and paste***********

This is with 230400

2002-08-03 09:55:30 EST: 501 / 81
Your download speed : 501270 bps, or 501 kbps.
A 61.1 KB/sec transfer rate.
Your upload speed : 81020 bps, or 81 kbps.

I'll try the other stuff now, thanks for all the input:D

[Zziggy00]

Well I tried what mnosteele52 posted and the results were:

2002-08-03 10:15:59 EST: 502 / 81
Your download speed : 502576 bps, or 502 kbps.
A 61.3 KB/sec transfer rate.
Your upload speed : 81004 bps, or 81 kbps.

so i guess i'm just pretty much tweaked out on my side of the line, I'll finally call my ISP now and ask them what kind of speeds I should be getting at min. and compare that to what i'm getting now. Thanks again for all the effort you guys put into this, greatly appreciated.:)

[mnosteele52]

Zziggy00 you should be able to get more speed than that, it's not your settings it's something else. Try what this (http://dslnuts.com/DSLwiring.shtml) article says and also try the following:

1. Open Internet Explorer and select Tools - Internet Options - under the General tab in the Temporary Intenet files section select the Settings button.

Select Every visit to the page and set the amount of disk space to use: to no more than 80MB. Now select the Connections tab and select LAN Settings make sure EVERYTHING there is unchecked and select OK.

2. For IE6 ONLY - select the Privacy tab and choose Advanced check the box "Override automatic cookie handling" and for First-party Cookies - Accept, Third-party Cookies - Block and check "Always allow session cookies. Now NO MORE SPYWARE COOKIES.

3. Another thing to do about once a week if you modem is on 24/7 is to power cycle your modem, just completely disconnect power from it for atleast 15 seconds and then power it back on.

4. Make sure you have the latest drivers for your NIC and set your NIC duplex settings as shown:

Right click My Computer - properties - device manager, click the + beside Network Adapters and choose your NIC from the list. Right click on it and select properties - advanced tab, look for a setting called "duplex mode","link speed" or "media type" highlight it and change the value on the right to "10baseT full duplex", "10mbs full duplex" - then select OK.
*note* DSL can be either full or half duplex mode contact your ISP to find out what they support.


:) :D

I did everything stated right there and I'm still getting the same speeds, I've fairly confident it's something on the other side of the connection, I'll call verizon.

I did a searh on the forums before i posted this topic and I saw you had posted that link then, I read the whole thing, and while preformance might increase a great deal, that's too hardcore for me and i'm using my computer at the other side of the house from where the telephone line comes in, I don't want the new phone line running all over the place. Once again though thanks for the effort.

[mnosteele52]

Yeah I know it's pretty in depth but Dannjr said it works great, just an idea to try.:)

[Zziggy00]

Now i see what Jim1133 was saying, i just was reading around in the newsgroups sponsered by verizon and i found this post.

I read a number of posts in this group before stating that the speeds
would be upgraded to 728, but I haven't had any bandwidth increase.
Was the increase supposed to be for everyone? I've still got the
640/90 package from when it was bellatlantic.net, would that be the
reason I don't get the new speeds? Or are they still not done with the
upgrades?

that's closer to my

512/81
