[Mike Basinger]

I get the following kernel error in Ubuntu 11.04 when I try to connect to a WPA/WPA2 Enterprise WAP.

It then does this about every 2-5 seconds. Wireless did start working, but this errors worry me.

[Mike Basinger (mike.basinger)]

This bug may have been fixed in the natty-proposed. Closing bug for now, and will keep an eye on it.

[Mike Basinger (mike.basinger)]

Still happening after natty-proposed upgrade, but some what less often.

[Jeremy Foshee (jeremyfoshee)]

Assigning to Henry Ptasinski per Tim Gardner.

[Henry Ptasinski (hptasins)]

Does this only happen with WPA/WPA2 APs, or does it also happen with open APs?

Also, which wireless chip is in this system (lspci -n)?

Thanks,
- Henry

[Mike Basinger (mike.basinger)]

It looks like just WPA/WPA2 Enterprise in my logs but will double check when I can.

[Henry Ptasinski (hptasins)]

How about WPA/WPA2 Personal?

I notices a few odd items in the log files:

- NetworkManger is unhappy:
> NetworkManager[834]: supplicant_interface_acquire: assertion `mgr_state == NM_SUPPLICANT_MANAGER_STATE_IDLE' failed

- There's an assortment of ioremap errors:
> kernel: [ 22.238216] ioremap error for 0x8b70b000-0x8b70c000, requested 0x10, got 0x0
but I'm not sure who's calling ioremap at that point.

- And a few of these:
> kernel: [ 672.821992] wl0: wlc_recv: dropping a frame with invalid src mac address, a2: 0f:06:53:69:6e:67
with various mac addresses. Any possibility of sniffing the traffic on the air to see if these are actual bogus frames vs. some buffer mangling happening in the receive path?

We'll try to repro on another 64-bit machine.

Thanks,
- Henry

[Mike Basinger (mike.basinger)]

On my WPA personal connection at home all but the wl0: wlc_recv: dropping a frame with invalid src mac address, a2: 00:00:00:00:00:00 errors are gone.

I can try to sniffing the traffic and post results.

And connectivity is ok?

Thanks.

I was getting with error with a Acer 722 with a Broadcom 4313 card when trying to sign into my WPA2 network. I was able to workaround it by re-configuring my home wifi/router setup. I originally had my dsl router and wifi switch on the same subnet, with my router assigning the address. I now have them on separate subnets now and everything is working correctly. If you have more than switch on your network try just connecting directly and then go from there.

Hope this helps.
