I use a network card to access my local Network, but a 56K dialup modem to access my ISP. What settings should I use?

TweakMASTER Knowledge Base article KB0045

If you are using a typical 10/100 Fast Ethernet Adapter for a network card, the question is, what do you do with the network card? Do you have a local network (LAN) you use where you transfer data and need speed there as well?

With Windows XP, it is now possible to set different MTU and TCP Receive Window settings for your network and dialup adapters. TweakMASTER camn handle this effortlessly for you.

With older Windows OS, it is impossible to really optimize for both a network AND a dialup connection at the same time in Windows. TweakMASTER will recognize this situation and will leave your TCP Receive Window set to default (0). Sometimes resetting just the MTU for your dialup adapter to 576 will help, but often that is not enough.

If you are not using the network card, or don't need speed on the network, then try going to the Advanced Optimization screen and selecting the Dialup adapter from the drop down list at the top where it says "interfaces".

Now go to TCP Receive Window and use the "set to" field and select from the drop down list MSS*8. It will prompt you to reboot. Then try your connection and see if that helps... it often helps people quite a bit. Bear in mind this arrangement might slow down your network connection noticeably if you access a LAN with older Windows OS.
