7304 no internet access

I install a 7304 on a embedded pc with Windows 7.
When I install drivers, it work well.
After the first time, the connection say me “no internet access”, and I have NO internet access.
If I wait some minutes, it start work.

I try the last firmware and drivers, but after the firt time it doesn’t work !!! Why ?
I have five 7304 boards but all say me “no internet access”.

Please help !

Hi,
Which driver you are using? also what is the FW in the module?

Also let me know the result of below commands:

ATI3
AT+CSQ
AT+CPIN?
AT+CREG?
AT!SELRAT?
AT!GSTATUS?
