I have a question about Change the MTU and RWIN Settings in Dial-Up Networking:

can I do this for windowsXP? I have looked but can't find them...am I missing something or just going blind? LOL

This Registry fix applies to ALL AOL users who installed AOL v4.0 or v5.0 32-bit 
software for Windows 95/98, and is aimed to obtain MAXimum transfer speeed on AOL, 
with a 28 - 56 kbps analog modem.
This is THE ONLY way you can force AOL 4.0 and 5.0 to use a MTU value other than 
1500 or 1472 (default), which is optimized ONLY for LAN/WAN networks, xDSL and cable 
and satellite modems, but NOT for analog modems, no matter how you connect to AOL:
using AOL as your primary ISP by dialing one of AOL's local phone numbers available 
in your area;
using another primary ISP to log on to the Internet, and then using AOL's TCP/IP 
protocol to sign on to AOL.
CREDITS: This workaround was successfully experimented by Arvid J. Bloom (ajbloom@aol.com) 
with AOL v4.0, and by Jeff Balliett (SEAL81044@aol.com) with AOL v5.0. Many thanks 
for sharing!

THE BUG:

When you install AOL 4.0 or 5.0 on your Windows 9x computer, it creates this new 
Registry key, you can see by running Regedit:

HKEY_LOCAL_MACHINE\SOFTWARE\America Online\AOL\aolsock

and in the right hand pane you'll notice one of these DWORD values (default):

mtu   0x000005dc (1500)

or:

mtu   0x000005c0 (1472)

THE FIXES:


You MUST apply this fix [delete the "aolsock" Registry key], and then set your TCP/IP 
MTU to 576, as described in the "AOL MAXMTU REVISITED" topic, also in AOLTIPS.TXT, 
part of my Win9x/2000/ME/XP + DOS 7/8 ©Tricks + Secrets files [W95-11D.ZIP], to make 
all this work properly!





On some Win9x machines you'll also notice this AOL 4/5 Registry key (using Regedit):
HKEY_LOCAL_MACHINE\Software\America Online\AOL\AolsockBack

If your Registry doesn't have this key, you need to create it: start Regedit -> go 
to:

HKEY_LOCAL_MACHINE\Software\America Online\AOL

right-click on "AOL" -> select New -> click Key -> type "AolsockBack" (no quotes) 
-> click OK or press Enter.
This is the "AolsockBack" MTU DWORD value in the right hand pane (default):

mtu   0x000005dc (1500)

or:

mtu   0x000005c0 (1472)

To create a new "mtu" DWORD (if not present) under "AolsockBack": right-click in 
the right hand pane -> select New -> DWORD Value -> name it "mtu" (no quotes) -> 
click OK or press Enter.
To change the MTU used by AOL to 576 (for MAX speeed) under "AolsockBack": right-click 
on "mtu" -> select Modify -> check the Decimal box -> type 576 -> click OK or press 
Enter.
Now restart Windows and log on to AOL.
According to Arvid (using AOL v4.0) and to Jeff (using AOL v5.0), their download 
speeds went from 1-2 KB/sec to 4-5 KB/sec, sometimes even faster, ONLY after applying 
this tweak!
Have fun.

hi all, I am from india. i use a win xp pro os. i have a broadband connection with a huawei mt800 router/modem. the problem here is i have configured my connection as a auto dialer, i.e i dont use the win xp inbuilt pppoe dialer but i use the dialer in the router itself. i configured the mtu as given in this website and it was 1472. what happens here is the connection stays alive for sometime and drops itself when i am browsing or downloading. there seem to be no problem with the connection becoz it works perfectly with the win xp inbuilt dialer. anybody has any idea abt this Thanks and regards Kirubahar
