Whenever I apply the driver update from TVSU for the HSPA module, the connection becomes unstable. Often disconnects or unable to connect, sometimes even settings (APN) are wipe from the wireless connection status.
However, I have recently discover that the driver provided by TVSU is identical to the driver that is on my system. (1.0.1046.223) Don't have much idea why TVSU still offers me driver update.
I also noticed that people here talked about the possiblility firmware updates for it, therefore I wonder is that the firmware or driver is actually causing the problem.
From when are you facing the problem?Ever since you started using the HSDPA connection or updating the driver?you may also want to check out recommendations made by lenovo if you are using WLAN.Check out the following link.
