Extreme Clod IQ - ap305c - firmware update issues - reboot loop

vazlavk — Wed, 04 Mar 2026 16:07:44 GMT

Hello,

got 3 used AP305C-1, was able to onboard them to Extreme Cloud IQ.

Initially installed Firmware was "10.7r5b" on all three of them.

Started firmware update to latest available version and ended up in reboot loop.
Only local firmware available to update is 10.6r4, wich was transfered to AP via scp / tftp.
Lost 2 days trying every firmware version available in Extreme Cloud IQ.
Only way to go is to flash 10.6r4 twice local and then flash 10.8r2 from Extreme Cloud IQ also twice, here after I can factory reset via pinhole or via cli.
Every other firmware version leeds to reboot loop either emediatly after flashing or after factory reset in any kind.

I'd be very happy with any kind of help.

The only error / warnings I can see:

Hello,

the problem seems solved.
The APs were all connected to a HPE OfficeConnect Switch 1820.
Somewhere in the community I read about LLDP in conjunction with OfficeConnect Switch 1820 and I also read somewhere in the release notes of different firmware verisions that from a specific version onward LLDP is enabled as default.
So the problem was LLDP and OfficeConnect Switch 1820.
Switched off LLDP and everything works just fine.

Seems sufficent to disable LLDP transmit on the switch port.
