I have 3 Aruba IO access points - AP11, AP12 and AP15. After roughly 5 days, I need to reboot the access points in order to recover from clients not getting a DHCP address / renewal from my DHCP server. I replaced my Unifi access points with the Aruba APs about 2 months ago.
I have the following setup:
3 x APs
HP 2930 PoE switch
DHCP server running on Ubiquiti USG (tested it from PfSense DHCP server and pihole DHCP server, but getting similar issues).
Clients varying from Windows, MacOS, Apple iPhones and IoT devices only using 2.4Ghz.
The 3 access points are at the same spot on a floor, within a 3 storey house.
I have not been able to do a tcpdump on the USG to see what happens when a client requests a DHCP address (and fail), as it always become noticeable during a critical point where the wireless service needs to be available.
The SSIDs (4 different networks) are configured to be in bridge mode and to use the vlan assignment per network. Under normal circumstances, everything is working fine, but when a client does not get a DHCP address, rebooting the AP resolves the issue immediately.
Because I cannot log into the access point itself (like you could with Unifi access points), I cannot see why it would not pass the DHCP requests between client and server.
How can I resolve / troubleshoot this?
