some years ago I bought a RUT104 modem. I received the latest firmware version (V2.00.r52) and in these days
I set up newsly the modem. I'm using it with a WIND 4G sim card but I found that after some minutes (tipically
4 minutes) the device is disconnected from gsm network. The reported signal is enough (25%) but it didn't connect.
The question is : With this release of firmware the device did support 4G sim ?
