I'm facing difficulties setting up the Fibocom FM350-GL modem on my ZBT WG1608 router using the zbt-wg1608-32m-go2024-01-17-ab23.zip firmware from rooterproject's website.
Target Platform - ramips/mt7621
Firmware Version - GoldenOrb_2024-01-17 ( OpenWrt 23.05.0-rc2 )
Kernel Version - 5.15.118
Unfortunately, the connection is not successful, and I'm encountering a significant error in the logs.
AT+GTRNDIS=0,1
ERROR
AT+CGDCONT=1,"IP","internet.tele2.kz"
OK
AT+GTRNDIS=1,1
ERROR
I've tried configuring the modem with the provided AT commands, but it seems to return an error during the process. The CGDCONT command seems to be accepted, but when attempting to activate the modem using GTRNDIS, it returns an error.
I read that an OpenWrt Kernel version of 6.1 is needed for this modem. However, it's worth noting that the most recent kernel version for MIPS architecture is 5.15. If anyone has experience with this or a similar setup, your insights would be highly appreciated.
