I’m replacing my 5G router from my provider with R4 , do I need to compile my own openwrt firmware and load kernel module needed for FM350 and mt7915 to work or snapshots will work out of the box for these cards ?
If you have answer please write your knowledge into the wiki:
It is important to know which slot do you want to use. I think you want to use the M.2 on the top side?
For this topic, I may found an answer for your question using the search “right top corner”:
today I received my R4 , asiarf 7915NP1 and it is working well , sfp tested with old Cisco SFP

FM350 arrived today , using latest snapshot
- satisfy_dependencies_for: Cannot satisfy the following dependencies for kmod-mtk-t7xx:
kernel (= 6.6.47~2fcfcca39c110f2e13a201fe126d6c72-r1)- opkg_install_cmd: Cannot install package kmod-mtk-t7xx.
Better update your snapshot image since snapshot kernel updates very frequently, and if it is updated this would happen. Also you can try to compile the kernel by yourself.
sorry but compiling is out of my league…

I’ve heard that fm350’s pcie mode has some issue, but I don’t have one to test… Maybe try usb mode?
fm350 doesnt show up in lspci both on openwrt and ubuntu , but its detected by modemmanager
