Ok, so support told me there is a known issue with the MR72's and 26.1 firmware. As a band-aide I've tested that disabling 2.4 GHz and only allowing 5GHz will work for the 72s, the problem is these are mostly used for our outdoor APs with outdoor antenna; where distance is more key and 2.4 would shine. Supports recommendation was for them to put all the MR72s in 25.13 firmware across the network which I agreed, until there is an available patch. I hope this helps others that have a similar issue.

Thanks, I've done just that. We've had a similar situation a little while ago with the same MR72s. We are on 26.1 across the networks because I read somewhere that there was a bug fix that was supposed to resolve some issues on 2.4 for those APs. I'll see what happens with the case and repost.

Is anyone experiencing issues with the MR72 for the 2.4 GHz band only? We are seeing devices either get 0.0.0.0 ip's or not connect at all. Connecting to 802.1x radius or WPA2-PSK does the same thing. We've narrowed it down to just those APs (we also have MR42s and MR34s in our environment and those APs are running smoothly). We updated to the beta 26.1 (which is supposed to resolve a few issues with 2.4) but we are still seeing problems. We have completely disabled 2.4 from our 72s and looking for feedback. Anyone else seeing this?
