hi lobo
Where do you find firmware
I currentl you use dsl and have trouble setting my max mtu and finding my optimal RWIN I know you are supposed to change the MTU on the router but to what amount (the same as the one on my computer?) and how?
its an alcatel speed touch home manual link
(that's the pdf manual)

SpeedGuide.net TCP/IP Analyzer
TCP properties for IP =
Note: Read the FAQ if the above is not your IP address.
Browser/OS = Mozilla/4.0 (compatible; MSIE 6.0; Windows 98)
TCP options string = 020405850103030001010402
MTU = 1453
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput.
MSS = 1413
Maximum useful data in each packet = 1413, 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) = 65535
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 65535
Note: Under Windows 9x, if you have RWIN set to any other value, and the Analyzer reports 65535 you might need to install the MS Vtcp386 fix.
For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
519984 (MSS x 46 * scale factor of 8)
259992 (MSS x 46 * scale factor of 4)
129996 (MSS x 46 * scale factor of 2)
64998 (MSS x 46)
bandwidth * delay product:
Your RcvWindow limits you to: 2621.4 kbps (327.675 KBytes/s) @ 200ms
Your RcvWindow limits you to: 1048.56 kbps (131.07 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 55 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349)= 00000000
2689 connections tested since 03.10.2001.
Analyzer version: Beta 0.99

okay well you need to find out where your install files for your access manager or whatever you use are. If you upgraded t it normally will be found under C:windows/temp
Next find the .inf file that corresponds it (there may be multiple but it will be easier to figure out)
the file I had was named ntspppoe.inf (sympatico) since normally the defalt setting is 1454 search for it. It should fall under max frame size change both occurances to 1494 (pppoe) or 1500 (everyone else). you will need you windows CD rom. And I believe you have to reinstall the program (access manager or whatever) so the settings are in.
Restart
after you restart, go to network neighbourhood, right-click, select properties. select the adapter (not the protocol for your your connection to the internet) go to advanced, maxframe size and change it to the number desired. restart and use the tcp/ip analyzer to check the settings.
The first part has to be done as the maxframe size is not allowed to go higher than 1454 you if you go into the registry and set it lower than that (or use cablenuts) it will work but not if you go higher.
Let me know if you need anything else.
