Hello All,
A new sealed Sierra Wireless EM7455 module with a usb NGFF M.2 adapter.
Flashed generic firmware twice and with a working sim,am only getting "no signal' when i do mmcli -m 0 for modem information in Debian linux
Have done two of these before and at same location. Only difference is my first two setups,I used an pci-e 1x to M.2 NGFF adapter. This adapter did come with 4dbm rubber ducky antennas. This only get about 50% signal at best at location
The new SW modem did come with the generic 'wire antennas'. I also had another pair of similar wire antennas i know has worked for testing.
Have tried to get familiar with the AT all over again ,but anyone have this happen on this series of modems. No Signal?
Thanks
