Cant connect to Cisco AIR-AP1041N-A-K9

OK I have a Cisco AIR-AP1041N-A-K9 Aironet Autonomous Access Point. Basically however i configure it i cant connect to it. I've been following this guide: https://www.cisco.com/c/en/us/support/docs/wireless-mobility/wireless-lan-wlan/67134-wpa2-config.html

It seems if I try to setup the local radius server with a username/pass and try to use EAP etc. it wont allow clients to connect. If I set it to use wpa personal with a single pass, it wont allow clients to connect. I tried using the EasySetup with a basic WEP and open schemes, still cant connect. I can view the set SSID, try to connect, but there is always a failure. What is going on?

tried to connect from win7 and android. Any ideas? Being powered from a Catalyst 3750 Switch.

This is it in personal single key mode, static IP 192.168.1.252, it was previously in the radius setup. :

- What is the failure ?

I don't know. windows or android don't really give much feedback. I tried to attempt a connection from win7 cli, with this:

netsh wlan set hostednetwork mode=allow ssid="open" key="XXX"

it claims success, but does nothing. (Admin cli). Either way not much useful info. The GUI just says "can't connect to open", "open" being the name of the ap. Is there a way to get some more info from win7? Android just says "Connecting..." then gives up and goes back to my old ap.

Event Log on ap does not mention any connections. Anywhere else i can check?

- Hm, in general this AP is a also very old model , consider using modern wireless infrastructure ,

Well i guess it is old, but reliable apparently. Thats why i went with it. New ones are too expensive, and surplus to my requirements. Turns out it was in root-bridge mode instead of ap mode. One guide told me to use root-bridge. Whats the difference?

- It's not that important , bridging mode(s) only refer to wireless infrastructure using cascade to provide networking

>...it is old, but reliable apparently.
- I beg to differ on that ; the problem with very old APs that it can lead to connectivity issues with clients following more modern wireless standards ,

Thanks, I've solved that issue though. Problem now is i cant enable the 5ghz radio. In network > NETWORK INTERFACE > Radio0-802.11n 5G.Hz > settings, i cant enable or disable it. Clicking apply does nothing. Same with easysetup. is there a cli example for 5ghz?

@mR_Slug the 1041 is a SINGLE band 2.4GHz AP.
Radio0 is the 2.4GHz radio.
If it had a 5 GHZ radio that would be Radio1.
That is why you can't configure 5GHz - because it's not supported on that AP!
The product went End of Support 5 years ago so Cisco have removed all documentation relating to the product.

Many thanks for clarifying that.

- AIR-AP1041N-x-K9: Single-band Standalone 802.11g/n

Whats confusing me is that it says g/n. I thought if it supports n it must do 5GHz? No?? It seems that you can do n on 2.4GHz only? I'm not disputing you, i was about to post that i cant find radio 1 in the cli. So this explains alot.

https://en.wikipedia.org/wiki/IEEE_802.11n-2009
"It seems that you can do n on 2.4GHz only?" - correct
g was the generation before n when data rates went up to 54Mbps (b was up to 11Mbps)
a and ac are 5GHz, ax is both bands + 6GHz
That link above has a table summarising them all.
