After meshing 2 R710s, several clients can't access the internet

[joel_reynolds_g]

For the longest time, we had the two APs separate because the first of the two was set up prior to me working here. That AP started disconnected randomly so I decided to reset it (because I didn't have the credentials) and mesh the networks as I thought that would be a good idea. However, as the title states, I have a handful of clients that cannot access the internet after meshing the two R710s.

Some notes:

• The clients can't connect may acquire a connection but it would be for 30m-180m. 
• Most clients experience 0 issues.
• When troubleshooting the MAC addresses I get the error code "(code
  6)Received class2 frame from non-auth STA"
• I have outright blocked all personal devices from connecting to the network until I find a remedy

I'm desperate for a solution, let me know if you have any questions and will be very appreciative of any help.

interesting. is there a Vlan in play? or do clients fail regardless of SSID/Vlan?
