Can't connect to unleashed randomly, so confusing

[richard_hosch]

I'll try to be brief...

Have 4 r710 in my house in unleashed configuration. Has been pretty solid for ~3 years.

Came home the other evening and wifi was out, nothing in the house connected. After two days of resetting APs, trying to get any of them in isolation to work, I concluded the Ethernet patch cable was the culprit - the only constant as I brought each AP to the same room to try and troubleshoot. That seemed to work. I was able to start over setting up the network, and everything, mostly, reconnected.

I noticed an odd device or two wouldn't connect. My son's iPad and a meta VR headset. The next my phone, which was connected the day before, wouldn't connect. I thought maybe too many IPs so I increased the range in my pfsense router to have 150 addresses available. Seemed to work, for a day or two.

Now my phone and my wife's phone won't connect again. Most devices in the house are connected. I'm getting "couldn't get an IP address" message on my phone most often when I try to connect. After restarting an AP or two, I've seen "failed to connect" I steady 

I downloaded syslog on the ruckus and can see where my phone's MAC apparently successfully connected to vlan1, then ten seconds later disconnected, then left. That was when I manually tried to connect immediately before pulling the logs.

When I turn on debugging in ruckus and enter my phone's MAC address, I see no activity.

I can't see anything in pfsense or the ruckus configuration that points me to what is going on. Really frustrating.

Any thoughts?

Update, head scratching continues. When I posted previously, my phone wasn't connected and the message had changed from "couldn't get an IP address" to "connection failed".

Last night when I got home, my phone connected immediately. And my wife's. And my son's iPad that had been disconnected. But my daughter's iPad still wouldn't connect.

Tonight when I got home, my phone wouldn't connect. Still saying "connection failed". My son's iPad was still connected though. But not my daughter's. 

Most "fixed" devices in the house, the ones that don't move like the 16 Amazon echo devices, a few appliances, a few fire sticks that aren't hard connected, a dozen or so Kasa smart outlet plugs etc... those seem to stay connected pretty solid.

So I logged in to the ruckus web config tonight, and the master AP was connected but the other three AP were in disconnected status. WTF? I just reset all of these a few days ago while troubleshooting and added them to the network one at a time. Despite all the other flaky issues this is the first time I've seen that happen. 

So I clicked restart on the master AP and got a message that it was rebuilding the unleashed network. Why was that even needed?

So I was thinking I was having some issues with the DHCP service in releasing IPs for devices that leave the network proximity and then return, or something along those lines, where I'd run out of available free IPs or something. But with this development tonight I'm wondering if one of the R710s is just having a hardware failure of some sort and releasing all sorts of ghosts into the machine? 

Any thoughts? I'm not even sure what to do to try and troubleshoot this craziness. Maybe disconnect one AP at a time from the network and see if the issues persist?

Oh, and after restarting the master AP and it trying to rebuild the unleashed network, now my phone is back to the "couldn't obtain an IP" message when trying to connect, for whatever that is worth.
