Cisco AP1041 as WiFi Bridge

Ok, just moved into a new house.

I plan on running hardline ethernet one of these days, I promise. But that isn't today.

I have an older Netgear R7000 Router that I have been using for a while. It still works ok, the entire house gets WiFi adequately, no real issues with this particular piece of equipment at this time.

I have 12Mb DSL. Yeah.... fastest I've ever had - b/c rural. That's ok.

My phone jack and DSL modem are on one end of the house. So is my router. My home office is in the middle of the house. My office has all my gear on 1GB switch and CAT6. In the past, I just used Powerline adapters and bridged the ISP over to my home office, and it worked out ok. Nothing blazing fast, but when your internet is a dinosaur, you don't need blazing fast to the router, all my big data is local on the faster network anyway.

In the new home, Powerline doesn't work so well - different circuit and all. So, I have this old AP1041 from work that was sitting in a networking closet. I know it only does up to .11-N, which is still fine for me. Reading up on it at work today, seems like it should be able to go into Bridge mode and replace my Powerline adapters.

Getting it home and working with it for a few hours, I can't get the damn thing to authenticate to my existing WiFi network. It seems ~mostly~ straight forward on the Cisco side (as straightforward as that gets anyway). On the AP, setting it to Workgroup Bridge is no issue. I can enter the SSID, update the Infrastructure SSID, and update the Security requirements to TKIP + AES, TKIP, or AES. But playing with the settings, I can't get the settings to associate. I either get Cannot Associate - No Response, or Cannot Associate - Associating, or Cannot Associate - WPAIE Not Found. Flipping between WPA, WPAv1, and WPAv2 doesn't seem to do anything.

I tried changed my WiFi security from WPA2 to WPA+WPA2 (my only other option is None, which isn't an option, or Enterprise, which needs a RADIUS server that I don't have set up at the moment). I haven't tried WEP yet, which I can select if I adjust a lot of the settings on the router, but that isn't really any different than None and breaks my existing SSID on every single other device.

Any tricks here? I know it's an older piece of gear, it may just be time to chuck it. I could just buy another cheapy bridge for like $30 until I can run the wire, or pony up for a UniFi at $100 and run it bridged until I get the wire run, then turn it into my AP. But if i can get this to work in the interim, it would feel like a victory to me in more than just the saving money front. It's become a bit personal.

Yup.

Code:
ap#sh ip int br
Interface                  IP-Address      OK? Method Status                Protocol
BVI1                       192.168.1.5     YES NVRAM  up                    up
Dot11Radio0                unassigned      YES NVRAM  reset                 down
GigabitEthernet0           unassigned      YES NVRAM  up                    up
ap#

Here's a log output when restart the AP and then re-enter the PSK in order to see if it will reconnect. This is with Encryption set to AES CCMP, The SSID set to Open Authentication, Mandatory Key Management WPAv2, and the Netgear router set to WPA2-PSK (AES) (which is the config I think should be working).

Code:
ap#sh log

It looks like it's trying to peer with another Cisco AP that is designated as a station-role root. What is the full config of the AP?

I reset to factory, changed the password, set a static IP, set Workgroup Bridge, and tinkered with the Security settings to try to get the SSID to associate, here's the config:

Code:
