AP not registering

sqambera — Mon, 05 Jul 2021 15:41:31 GMT

Hello,

I have WLC 5520 to which already number of 2802i APs are registered. However, when I am trying to register a new AP it fails. I have noticed that it registers initially but then attempts to download software from the controller. Once the software is downloaded it doesn't register again. Same is indicated in the attached logs.

Can anyone please help?

Thanks,

Qamber

Post the complete output to the following commands:

1. WLC: sh sysinfo; and

2. AP: sh version

I am suspecting the AP has the wrong Regulatory Domain.

I think you are probably hitting one of the bugs in 8.3.140.0 which is why that code has been withdrawn. You should upgrade to 8.3.141.0 asap otherwise you risk losing any of those APs each time they are rebooted.

https://www.cisco.com/c/en/us/td/docs/wireless/controller/release/notes/crn83mr4.html#whats_new_release_83mr4b

Table 2. Resolved Caveats in Release 8.3.141.0
Caveat ID Number	Description
CSCvi11287	Cisco 2800 AP consistently reboots around 1 second after joining to the WLC
CSCvi14641	Cisco 2802, 3802 APs cannot connect with 100Mbps LAN speed

Thank you everyone for the help. I figured out the problem. The Ethernet wire was not good 🙂
