Huawei E160 Help!

[Brozy]

Hi, i got a contract with Tmobile with one of the E160 sticks in april this year, everything worked fine until roughly the start of this month when anywhere between 5 mins - 3 hrs the connection sort of hangs, still connected but just doesnt do anything and doesnt resolve until i reset the connection and even then it sometimes still persist.
I mostly play WoW so its almost always noticeable when it happens and with it happening randomly makes playing it rather pointless because you dont know when the connections going to hang.

I've searched and read various threads/forums trying to find out an answer to my problem and noticing a few saying to update the firmware which ive managed to do but the problem still persists and i have tried using 2 other firmware versions that are to said of solve the problem, so i was wondering if anyone here happens to either have the same problem and fixed it or know anyway that i may be resolved, i have tried the following firmware versions if that will be of any help:

E160Update_11.604.21.00.156.B409
E160Update_11.608.05.00.00.B409
E160Update_11.609.08.00.156.B409

Any help would be appreciated and sorry if this isn't the right place just couldnt find anyother place that may be able to help and also for the long post.

Did you check the same connection with another modem?
