Hello!
I've been using OVMS successfully for about a month now. Everything used to work great, but now somehow my modem does not connect to the internet anymore. I've checked the SIM in another device and it is working normally.
This is the output from the log. Any ideas?

REPORT ENDS
Hmm, looks like this was some connection issue with the antenna. I've unplugged the modem board and checked the antenna connections, reassembled everything and it started right away again...
never mind :)
Same issue again
Looks like my GSM signal Quality has significantly degraded since the device was new. Already tried a different antenna and checked the internal connections. But I can barely get any connections.
Any suggestions?
stesso problema anche per me ed è il secondo modulo!
stesso problema anche per me ed è il secondo modulo!
Try swapping the internal GPS / GSM antenna cables (so swap them on the modem board, and then swap the external antennas as well). That will tell you if there is some issue with the internal cables or their connections.
I've already tried this. It did not help. Also checked all connections with a multimeter and they seem OK.
I guess something is wrong with the modem board...
Any suggestions?
Otherwise I will try to get a refund. It is not working for me anymore.
