Problem with connection?

Hey all,

I just bought a new hard drive and made it my master drive. So of course I went through and reinstalled win98se. After doing so I used the speedguide tweaks like I usually do. Now I am getting some horrible dl speeds. Averaging around 600kbps. I used to easily get 1500kbps. I am with @home, which in my area is going to be insightbb/at&t soon. I have tried numerous rwin settings and I get the same result for each. I ran the analyzer and this is what my settings are at right now.

MTU = 1500
MTU is fully optimized for broadband.

MSS = 1460
Maximum useful data in each packet = 1460, which is equal to MSS.

Default Receive Window (RWIN) = 256960
RWIN Scaling (RFC1323) = 2 bits
Unscaled Receive Window = 64240
RWIN is 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)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)

bandwidth * delay product:
Your RcvWindow limits you to: 10278.4 kbps (1284.8 KBytes/s) @ 200ms
Your RcvWindow limits you to: 4111.36 kbps (513.92 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 56 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000

If any of you have any suggestions I would sure appreciate it.

Thanks

Are you getting those speeds anywhere you visit online, or just one particular site? Try pinging your gateway to find out if you have any packet loss on your connection. Click on Start, Run, type WINIPCFG and hit Enter. Then Click on Start, Run, type COMMAND, and inside that black window type PING [whatever your Default Gateway is] -t. If the numbers are higher than 40ms of if some time out, you may have a connection problem with your cable modem.

Thanks for the ideas.

I am behind a router so I pinged both my router and the gateway from my provider, neither showed bad pings. My roommate who is also on the router is having no problems, just me. It acts like there is a cap on my side or something, because no matter where I try to dl something from it starts high, like usual, and usually levels out at about 80-85 Kb/s now. I used to get way over 200. This is quite frustrating because I can't think of what I could have missed.

Have you updated the firmware on your router?

GrandFlash13 · Post by **GrandFlash13** » Thu Feb 07, 2002 5:46 pm

Yeah, just did that last night.

It's likely that you missed nothing. You're still on @Home, and its performance has been slipping steadily. 21 more days it will be so steady that it won't even move!

I am just hoping that is it, just wanted to get some input from others in hopes that someone would say "Did you try this?" and I would say "Of course" then go and try it and it would clear up. I do know that they are changing things over right now and getting ready to launch thier own broadband in about 2 weeks so most likely that is it. Thanks for the tips though MosDef.

Sure, any time.

As Kip said, it's likely @home and their imminent network shutdown. It is very unlikely that they're maintaining it with only less than a month left before turning the lights off.

Dude....I think your RWIN is too big. I don't think WIN98 recognizes more than 64K RWIN. Even then, I usually keep mine set at 32K. You're more suceptible packet loss with a huge RWIN.

I went through tons of RWIN's. I settled on RWIN=65535. It seems to do the best job.

The RWin is not the problem. I have tried every setting possible and nothing seems to change my speed. I have now connected my computer to the T1 line at work and there was no change. There is something in my computer that is limiting it to 600kbps and it is starting to really annoy me. Here is what is in my computer, if any of you have a clue as to what it could be, please HELP.

Asus A7V133 bios 1007
Athlon T-bird 1.2ghz(not o/c)
512mb ram(256 Value Ram, 256 PNY)
Visiontek G-Force 3 ti 200
Hercules Game Theater XP audio card
Netgear FA311 (recently changed from the linksys 100tx)
Win98se
enermax 350w PSU

Something is not right. Something is capping my dl speed and the only other thing I can think of is to reinstall windows now since I believe I have tried everything else. If anyone else can think of anything, let me know. I am more then willing to try.

Thanks

Did the problems start after changing your NIC. Make sure it's set for half duplex.

GrandFlash13 · Post by **GrandFlash13** » Sun Feb 10, 2002 8:48 am

No, changed the nic to see if that was the problem. I have tried 10t, 100t, and full duplex on both, left it on auto sense as well and same thing for all settings. The newest stuff, all within a week of each other is another 256 ram and the hard drive. I believe this problem didn't come up until after I installed the new hard drive(5gig partition for windows and the rest for programs) which is a WD 60 gig, plus I have a 30 gig WD in it as well. Maybe just a bad install of windows? No clue.
