Fibocom FM350-GL Support

Then you do have USB and can use almost any mPCIe-to-M.2(NGFF) adapter available on the market, with or without SIM. The adapter description should include something related to mobile broadband and not mention wifi or storage.

USB2.0 will not work, only 3.0+. The mtk-t7xx pcie mhi driver is super buggy on even current snap openwrt ( kernel 6.6 ), dont bother with pcie mode for that modem before next LTS Kernel, maybe 6.12 or 6.13.

I guess only if you have usb 3.0 or better this modem will work for you. USB2 will not be able to detect it.

Fortunately this is not the case:

Can you do lsusb -t ?

I was not able to detect it on usb2 port on x86 or on the m2 keyb port from the bpi r3, also only usb2.0. Or more precise it did not expose the option or rndis ports.

According to docs it should not be backward comp. with usb2

"high-speed" already says it is USB2

lsusb -t

Ah it uses the other mode :7127. With 7126 this was not possible for me. Will switch it and try again, nice to know thanks.

480M clearly USB2. This should easy give between 280 and 320Mbit.

hi mate i am able to use this to get internet on my openwrt rpi4(able to get internet via ssh/ able to download packages in lucy),
it only has one ethernet port,
how can i route the 5g internet(coming from 350gl via usb) through the ethernet port, and get internet on my laptop?
this is the screen shot


@PMGZED mate any advice please?

Use the wan interface with the firewall zone wan ( red ). Delete your eth1 interface and attach the bridge br-lan back to the lan interface. Give the lan interface an address range like 192.168.1.1, Subnet 255.255.255.0 ( /24 ). Use the wan interface with the at commands protocoll to dial the modem. That should work as basic setup.

Btw that setup from you looks wild :slight_smile:

I think your configuration should look something like this:

Change firewall zone for your modem (eth1) to wan (red).
Delete your wan (eth0) interface.
Assign an IP-address 192.168.1.1 and subnet 255.255.255.0, to the lan interface ,as @klojsch mentioned, and activate the DHCP server.
Add eth0 to the lan bridge.

you should do the interface for the internet to the red firewall zone.
add interfaces connected to the internet to the green zone is a very bad idea!
