[ts-7000] 3G internet stability problem

[Simon Leung <>]

Hi all,

I'm using a ts7800 + USB 3G broadband stick for a remote monitoring 
system. The USB modem I'm using is Huawei E122. wvdial works fine for 
providing connectivity. But after a while (varies from 1 to 5 hours), 
the link will be down, wvdial will exit and kernel will think that the 
device is disconnected:

     option1 ttyUSB0: GSM modem (1-port) converter now disconnected from 
ttyUSB0
     done!

Anybody has suggestions as how to improve this situation? I don't expect 
mobile broadband link to stay up as long as a wired connection but it 
would be nice if it lasted a bit longer!

Thanks and regards,
