Problem getting wireless networking card working

[gchen]

Hi,

I was setting up a small office wifi and secured by WEP.

- Router is DI-254 (a DLINK old model), WEP enabled.
- 4 workstations linked up via WEP without problem.
- One laptop and one desktop were not able to establish links to router.

I have tried netgear's wireless network card, dlink's and USRobotics. The first two wireless cards did not work and i found out that my router's MAC ID is 00-11-90-75-33-AE. The interesting thing is when i use the first two wireless card, they read the router's MAC ID as 00-11-90-75-33-AD.

Every digit is the same except the last one, AE became AD. I guess that's why they don't talk to each.

However, when i simply change wireless card and associated driver to USRobitic card, it WORKED!

Now, I could not find the same USRobitics card, Best buy, circuit city, walmart they don't carry this brand.

Does anyone know why the MAC ID being shifted on character?

How do i fix the problem and get Dlink or NetGear card working.

If this is not the right forum, can someone point me to the right place for help?

Thanks millions!
