I used "firmware-selector.openwrt.org" to download 22.03.3 for the Raspberry Pi 4B/400/4CM (64bit)
About this build
Raspberry Pi 4B/400/4CM (64bit)
I’m using a SixFab Raspberry Pi 4G/LTE Cellular Modem Kit for connectivity
OpenWrt starts fine, with a default Ethernet interface
When I try to add another interface, managed by ModemManager, I get a “PermissionError - Access to command denied by ACL” with a red banner
I can’t edit the non-functional interface without getting the same ACL error
All I can do is delete the interface
I have tried both the 32bit and 64 bit versions with the same problem
No errors show up in Luci/Status/System Log
I’ve spent a few hours Googling with no success
Any ideas on how I can diagnose and fix this please?
Thanks very much!
