MC7710 3g connection Stability


I have many appliance with the Module MC7710 , but the 3g network connection is not really stable.

I don’t really understand why

After while i loose internet connection (Ip address are correct

After restart impossible to establish a new connection

I have to switch on/off several time until the network interface disapear from network connection Panel and reapear

And after i will be able to establish a new network connection

I have the same hardware with another mobile broadband cards MC7305 , i don’t have this problem

I got this problem only with MC7710
