My RUT240 does not connect to network. I have been using it already for months and out of the blue it started having this issue. The sim has no problem, I've checked this with the provider too. I've tried to reregister and to do a factory reset but nothing's worked. Also, auto APN is unchecked and I've updated the firmware.
To be honest I have no idea what else I could try. Yesterday it was working for half an hour and then stopped again. No idea!
Any help would be very appreciated! Thanks!
