@jake26 system is not on right now but it connects with 2.4 and 5. It is pretty far away from router and has a floor and a couple of walls between. So pretty happy that it connects as it does.

@skiingj when you go to the wifi settings on the computer, it will show you what frequencies you are connected to. With the MLO settings it will show 2 of them if it is working correctly.

@jake26 Try the driver in the link I posted above. Fixed the connecting on just one channel issue for me.

@jake26 Try the driver in the post here: Archer TBE550E won't connect with 2 channels on MLO network - Home Network Community It is newer then anything posted on the website and made it so my adapter...

@Ramburner Try the driver that is in the post here : Archer TBE550E won't connect with 2 channels on MLO network - Home Network Community It is newer than any on the support site.

@KenV99 Sometimes the best thing to do if you are having issues after an update, is to do a Factory Restore. It can be a hassle to do this but usually worth it in the long run.
