1 AP250 out of 20 at one site is having trouble providing network access. Devices can connect to it and receive an IP but they will lose any sort network access. What should I be looking at? Please help

At one of our sites we have 1 AP250 that is having trouble with network passthrough. Every device should be configured with a standard the previous tech should have put in place but I found that every device is configured independently from the actual radio profile.

This device in particular didn't have the Native VLAN values needed...which after I entered, every device was able to finally get an IP and work!

Now devices that are connected to it will stay connected but seem to lose any network access (can't reach internet, company shares etc...)

This AP has apparently been a problem for the users near it for a couple years and IT is now finding out about it..... the application guys have just been telling the users to reboot a million times.

Looking at immediate errors or diagnostics show nothing but good values...

Any help would be great! Thanks!

​Actually, I misspoke.... its anything on that AP on all SSID's.

​It's been every device connecting to the AP on SSID Peru - I could give you a few to work with: CK3B21021239424, CK3X191X1500124, CK3B21221039292

Is Roaming via layer 3 better?

Thank you for those captures. Can you tell me the MAC address of the client that was having issues so I can filter for the correct traffic?

As for the GRE tunnel, you don't need this for standard DHCP, only if you intended to try to roam via layer 3.

What about the turning GRE on for Layer 3 Roaming Threshold? Do i need this on or off?

I actually took a capture of this a few days ago.... but i will also provide a new capture of the wifi0 only - i turned off wifi1
