I recently got the Deco BE65 and I'm trying to connect my Surface Pro 12 (Snapdragon) to its network. It works perfectly fine on the regular network but when I try to connect to the MLO network, it says "Unable to connect to this network". Thing is it worked a few days ago when I initially connected to it but now it just doesn't seem to work. My phone and PC can connect to the MLO network without an issue.

My theory is either a Windows update caused something to screw up and not work with snapdragon/windows arm OR maybe my router updating its firmware and making it not compatible with snapdragon. I think my surface connected before the firmware updated but I can't fully remember the timeline.

I've tried uninstalling and reinstalling the network adapter/driver, restarting my computer, rebooting my router, resetting my router to create a new network and forgetting the network to reconnect to it. Nothing seems to work.

Should I just give up and turn off the MLO network, and just stick to the regular network? I've read about this issue being common due to firmware updates or windows update.

And any ideas as to how else I could try solve this issue?
