Default Signal/connection lost on wakeup after kitkat update

I have I9505 international. After kitkat update i noticed Signal and connection lost on wakeup .I tried dozen 4.4.2 roms all are stock i flashed at least twice.when phone is idle for long time (eg when awake in the morning ) and i unlock the screen signal is present....BUT if i connect to internet i lose signal. Aeroplane mode does not help. Restarting get signal back again. I tried different 4.4.2 roms and modems with no help. Any help is appreciated.

I had this issue because Odin did not flash the modem correctly (kept the older one from previous ROM). Flashing it again helped. You can extract the modem.bin from the FW file and flash it via Odin directly. Verify the baseband version if it really flashed it, though. There seems to be some Odin bug and I found some threads explicitely advising to flash the modem twice.
