X200 Mobile Broadband Problem

[guwester]

Hi

I have a problem with my Mobile Broadband Connection on my X200.

I am using a F3507g WWAN card. When i start up the x200 i have good mobile connection and internet access. However after using the computer for a while, i will lose my internet connection. The connection to my mobile provider is still good but there is no internet access.

Even if i disconnect and connect to my mobile provider again, there will be no internet access. the only solution is to restart the computer and i will have internet access again.

Occassionally i will also have the Windows blue screen with the error msg something like "IRQL not equal or less"

Can anyone solve my problem?

Thanks
