need help with DSL

TCP options string = 020405860103030201010402

MTU = 1454
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput.

MSS = 1414
Maximum useful data in each packet = 1414, which is equal to MSS.
MSS is not fully optimized for broadband (although it might work well for slower connections). Consider increasing your MTU value.

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:
520352 (MSS x 46 * scale factor of 8)
260176 (MSS x 46 * scale factor of 4)
130088 (MSS x 46 * scale factor of 2)
65044 (MSS x 46)

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 = 50 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000

my ISP is Sympatico it uses PPPoE
my specs: p3 450Mhz, 160MB of RAM & WIN98SE

are my settings correct?

Have you downloaded the patches provided by Speedguide? If not, please do so, because your Rwin looks like it's not from our product. You can try the tweaks below, except the Ramdisk trick if you are inexperienced with Computer or have 128 or lower Ram.:)

ESC, that is correct RWIN our patch puts in for DSL:)

Are you using EnterNet to connect? If so, you'll have to do this in order to change your MTU value. If this is EnterNet 100, then you can change it in the Network properties. Right click Network Neighborhood and select properties. Choose the adapter EnterNet created and select properties. You'll see that MaxSegSize there set at 1454, just set that at 1492 and you're set.

If this is EnterNet 300 do this: This is all *prior* to installation (yes, that means uninstall it before doing this). Either you have a Zip file of it or the CD, all the same. Browse the file for all of the *inf files. Everytime you find one, open it with notepad and edit it. What you're going to edit is the number 1454, click Edit > Find and type 1454 then hit Enter. Everytime it finds 1454 change it to 1492. When it's done finding 1454, save the inf file and go to the next one. Keep doing this until there are no *inf files with 1454. There you should install EnterNet and now it's default MTU will be 1492, optimum throughput.

Good luck

Also, I bet your computer hangs while restarting and shutting down, correct? I'm not sure if you have done this yet, but it's worth a shot.

1. Click Start>Settings>Control Panel
2. Double click Network
3. Look for your network card. (Make sure it's a TCP/IP protocol) Example: TCP/IP Lynksis LNE100TX Fast Ethernet Adapter
4. Click it and choose properties.
5. Select IP Address from the tab.
6. If Obtain IP Address Automatically is checked, uncheck it and choose Define IP Address.
7. Enter 192.168.0.1 into IP Address.
8. Enter 255.255.255.0 into Subnet Mask.
9. Click Ok on each Window and when it asks to reboot, do it.
10. Now your browser won't hang, neither will your computer when it boots up and shuts down.

"Windows 98SE NDIS Update
Symptons
On a Windows 98 Second Edition-based computer that is using networking software that is implemented as a Network Driver Interface Specification (NDIS) intermediate driver, one of the following symptoms may occur:

The computer may stop responding (hang) during startup or shutdown.

Your network throughput and overall network performance may gradually decrease, sometimes to the point that the computer hangs or becomes completely unresponsive to network requests.

Resolution
Download the file '243199US8.EXE' (http://broadbandnuts.com/patch/243199us8.exe)"

This is a critical update for Windows 98 SE users only. I see you already have the Vtcp386 update, good job.

Hey, I had the same problem in changing the MTU from 1454 to 1492 as read by TCP Analyzer. The tweak in my Network Neighbour for Telesystem PPPoE was set to MaxFrmSize: 1454 and is the highest it will go. The only way I was able to change the MTU was to manually change it in the registry.

I had to manually change it the registry under LocalMachine/System/CurrentControlSet/Services/ Class/Net/002 (Max Frame Size: 1492)
