indows 95/98 MTU problem.Microsoft has not released a fix for this yet, but if you download and run:"http://www.aimnet.com/~jnavas/modem/tcpipcfg.exe" (no quotes) and change yourMTU value to 576 (the default is 1500), it will correct the MTU "bug" inWindows 95 versions 4.00.950 (retail), 4.00.950a (OSR1) and 4.00.950 B (OSR2),however, I have been unable to get TCPIPCFG.EXE to work when MicrosoftInternet Explorer 4.0 or 4.01 for Win95, or Windows 98 (with IE 4.01 SP1)were installed on the system.Update: [3/20/1998] A concerned reader (zrock@kermode.net) writes:I just read your modem tips file and you should clarify the MaxMTU fix. Thesetting 576 doesn't work for all ISP's it can range anywhere from 512 all theway to 1500.... 1500 is where my ISP's setting is set and where I get the bestperformance. I also noticed that just using MTUspeed to add the 1500 settingmade a difference even though it is the Win95/98 default. I also noticed moreof an improvement by installing Microsoft's Unimodem update (a hugedifference) then rebooting, uninstalling my modem (rebooting), thenreinstalling my modem drivers I jumped from 2.1 k/sec to over 3.0 k/sec.CptSiskoX@Geocities.com and zrock@kermode.net========================Max ISDN SpeedUnless you use ultra-high-speed serial boards or special buffers, an externalserially connected ISDN modem will always result in slower performance than aninternal ISDN modem. This is because the 16550 UART maximum is 115.2Kbps, notthe 128Kbps a dual-channel ISDN connection is capable of reaching. If you wantto get every drop of performance out of your ISDN modem, use an internal one.CptSiskoX@Geocities.com========================Build a Bigger BufferAny modem user has probably received an important transmission with charactersmissing. There is no way to find and retrieve the lost characters, but you canincrease your odds of receiving data intact by adding a line or two to yourSYSTEM.INI file. Before starting, it's importa...
