AP doesn't join the controller after I try to reset it.

frankfurttt — Wed, 22 Feb 2023 09:50:13 GMT

Before I used it, I don't know what the previous person did, so I did a reset. After I plugged the console into the AP, then the commands came up:

[*05/09/2022] Waiting for uplink IPv4 configuration
[*05/09/2022] Waiting for uplink IPv4 configuration
[*05/09/2022] Waiting for uplink IPv4 configuration
[*05/09/2022] Resetting wired0 and restart DHCP client
[*05/09/2022] ADDRCONF(NETDEV_UP): wired0: link is not ready
[*05/09/2022] ADDRCONF(NETDEV_CHANGE): wired0: link becomes ready
[*05/09/2022] wired0: 1000 Mbps Full Duplex

After these commands keep coming up Then I thought the AP reconnected itself.

So, I did some research to fix it. until I can find a way to join the controller. I thought my problems would be over but not at all.

I thought my problems would be over but not at all. after that I think I made it connect to the controller, but I think I still can't because I see commands.

It's a lot but it's all the same. Until finally I think the AP tried to reconnect. But it went on and on like this.

I try to leave it with all day researching. I'm still not sure about this solution. Do you guys have any advice? Please help enlighten me. I'm newbie and I don't have enough knowledge to fix it yet.

If you guys need any other information, please tell me.

Thank you for your reply.

1. Access point model: AIR-AP1852i-s-k9 (IOS Version 8.5.161.0)

2. Controller model: Cisco 2500 Series Model 2504

3. Controller software version: 8.5.161.0

I hope this information matches what you need.

Thank you for your help, M.

I tried to learn about the information you've responded to. But I still have another's APs with the same version and the same model that can still connect to the controller and still active. Can you explain more about the information to bring?

I'm sorry to ask more, because I'm a beginner for this.

- You may try to factory reset the access point too and try again,

I would advise to update software to 8.5.182.7
@Mark Elsen it's very risky to recommend anything earlier than that now because they could be affected by the field notice (below) depending on what APs are in use. This is also the TAC recommended release now (link below) so we should only recommend that 8.5 release now - nothing earlier. The software download page will probably never be updated because (1.) 8.5 is End of Life and (2.) 8.5.182.7 is a hidden release only linked from TAC recommended and FN pages. So the golden * for 8.5.171.0 suggested release is just misleading and wrong.

If still no progress after software update and factory default reset of AP then you might have a faulty AP which needs RMA.
