Hi guy, im using r4 with 5g modem. I applied an openwrt as os on the router. I upgraded the system but after upgrading i lost my internet access. What the problem could be?

Which 5G module are you using ? see if you can see them from “lsusb” command.

Using quectel rm551 global m.2

I think i downloaded raw openwrt version,

I assume you are using the 5G modem in USB mode, see if you can detect it using “lsusb” command by logging into terminal It will show something similar
