Problems with Sierawireless EVDO Card on Thinkpad T60

My ThinkPad T60 is configured to connect to my cell carrier via its internal Sierra Wireless 1x EVDO adapter controlled by the Windows XP Network Connections. The remaining networking connections are controlled by the Thinkpad Access Connections utility. This arrangement worked stably for over a year. When I now attempt to use the WAN connection, I receive three Error 711 messages; the first two state "Cannot delete saved password" and the third "Cannot connect the phonebook entry". The same error is reported with the WAN card switched on and off. Device Manager indicates that the WAN card is working correctly.

The Remote Access Connection service is running normally.

I have run sfc and checked for spyware. Running system restore fixes the problem but it returns shortly.

Any suggestions as to how I might proceed would be very much appreciated.

Is this XP ?
Have you checked that it is not one of the MS security patches that is messing this up ?

have you checked to se if there is
1) new drivers

2) New software versions

 
I hope this helps !

An additional symptom: I attempted to set up a new connection using the Sierra card, at the last step in the process, I received the following message: "Unable to create the specified connection. This can be caused by insufficient memory or not enough disk space". The laptop has plenty of both.

If it were an MS security patch, then restoring to a prior date (well before the problem occurred) should work. I will check for a new Sierra card driver. I have tried installing the new version of Access Connections but that did not have any affect. Thanks.

Well depending on what shortly means, it could be  that automatic windows updates are messing it up again.

I would also check the hardware. Overheating or bad / flakey hardware may be causing  an issue.

Lastly do a diagnostic on the hard drive to make sure that it is OK.

Replacing the WAN card driver (with the same one) did the trick - which would imply that it was corrupted - but if it had been then System Restore should have replaced it with the old uncorrupted version - it works now which is what matters. Thanks for the help.
