Hi!
Im been using this router for 1 month and had no issues or the need to change any settings or update firmware.
Since 2 weeks ago my router suddenly dropped internet connection and when i got it re-running the speed dropped from stable 300mbit to 15-40mbit and now disconnects frequently.
I tried to upgrade the firmware to 4.7.4 and that made things even worse so i downgraded to 4.4.13 (since i dont know the factory firmware version).
What firmware and settings do you recommend to use?
OpenWrt 21.02-SNAPSHOT
Modem: RM520NGLAAR03A03M4G
Firmware: 4.4.13 (works best with tapo cam when reboot)
Multiwan disabled.
Apn settings manally set with filters.
When i run my old mr600 router with the same sim i get no issues.
Yours,
Sebastian
