ISDN tweak guide (Windows 98 & ME)

Now that it has become economically viable (& available), many people are choosing ISDN. ISDN Terminal Adapters (TAs) are rather more limited in how they can be tweaked. However there are still several things you can do to improve performance.

Updating drivers/Identifying the TA

First of all you should update your drivers. If you know how to do this then skip the next section. Hold ALT & double click on my computer, select the Device Manager tab & open up the Network Adapters tree.

You should see your ISDN card listed. Remember your exact model, as many manufacturers release several different versions of the same card, each needing different drivers. You should be able to find all the drivers you need at Windrivers. Update your driver using the instructions provided; some cards (like my one, for instance) have to have the old drivers uninstalled before the new ones can be installed.

If you are using Windows 95 or 98 still then you should be sure to install the Dial-Up Networking 1.4 upgrade. This includes an updated TCP/IP stack (For Windows 95) as well as other improvements to stability & security (e.g. 128-bit encryption).

General tweaking

Once your drivers are updated open My Computer & go into the Dial-Up Networking folder. Right click on the appropriate Dial-up connection & select Properties.

You should connect using your primary channel (0), for the sake of simplicity. Click on configure and make sure Only connect at this speed is not checked. If it is you will not have the option of connecting at 128k.

Click Ok and move on to the Server types tab. As far as I can tell enabling Software compression does not speed up transfer rates at all, so its best to disable it to avoid excess CPU usage. If you choose to Log onto network connections will be about 3 seconds slower than they need to be, I would recommend disabling this. Some servers may require an encrypted password, this will add a second or two to connection times. The other Advanced options should be left blank, unless you have a specific need for them (e.g. recording a log file to analyse connections). You can safely disable (Untick) NetBEUI & IPX/SPX if these protocols arenít installed on your system.
