390x freezing with wireless cardbus

[frontliner]

Hi,

I use a 390x as car computer with touchscreen for gps nav, playing mp3 and wlan for remote update, wardriving, etc...

The problem is that when the two cardbus slots are activated (usb 2 generic card + orinoco gold wlan card), the computer quickly freezes when wlan is active. It has XP SP2, 256mb ram. No hardware conflict, hardware acceleration has been disabled and i also tested with a linksys wlan card with same problem...

So, the solution i found temporary is to never use them together.

So, i open a session using the usb2 with the gps antenna for navigation and mp3 playing with the wlan card disabled at startup or i open a session for wlan with the usb2 card deactivated and no gps but the wlan card enabled, then the PC never freezes...

The computer already has the latest bios version and also latests cards drivers versions so i don't know...

I suspect a memory lack problem so i plan to order for two 256mb sodimm modules to upgrade from 256 to 512mb (supported by this 390x PIII 450mhz 2626L0G)...

What do you think about ? Do you think it could really solve the freezing problem if i upgrade to 512mb with IBM original modules ?

Thank u.

Welcome to the forum!

I doubt more memory will help your situation. It sounds like a software conflict, and the drivers could be to blame. Since those are kept in memory all the time, adding more memory will only make the applications more responsive, not the drivers.

I would see if new drivers are available for either or both cards.

You might also try a Linux LiveCD such as Knoppix (or Fedora, Ubuntu, etc etc etc) to see if that will allow both to work.
