Hello,
Got an issue with USB wifi not starting automatically, hoping for some advice.
OpenWRT 22.03.2 x86_64 acting as router.
PCIE slots are used up, so added a USB WiFi adapter to get 2g and to hopefully ensure easy access to router should the 5g card fail (or i miss-configure it when tweaking it outside of luci).
But after power failure / poweroff, the USB device does not re-appear as a WiFi device without some hoop jumping which requires access to the router.
I have to unplug it and re-plug it in and then /etc/init.d/network restart
The device is a Mediatek M7612U on a USB extension cable + docking station that it came with.
Upon startup wlan1 is not showing, device 0e8d:2870 is.
I unplug it, plug it back in, restart network and it becomes 0e8d:7612 WLAN device and wlan1 is working fine.
Do you know it its possible to tweak something so it starts correctly after bootup?
