At one place do not see wireless network anymore after upgrading to openSUSE 1.4

At a certain location I have worked with the wireless network when using openSUSE 11.3.
Then I upgraded to openSUSE 11.4.
After this I do not see the AP in knetworkmanager anymore. Also not when scanning.
I tried it with a notebook and a netbook. (And the netbook saw it when 11.3 was installed on it.)
On the notebook Windows detects the network.
My nokia N900 running Debian detects the wireless network also.
As far as I know, nobody else has a problem with detecting the WiFi network.
Untill now I did mind very much, but I have to work more often there and this makes it awkward.

What could be the problem?

It likely is a problem with missing firmware. Check the output of the dmesg command.

It would have been helpful if we knew what kind of device you have as shown by
the ‘/sbin/lspci -nnk’. Please post that output.

I do not find this likely, because the netbook did work. Also this is the only place -that I know of- that it does not work. All other places I work I do not have a problem connecting to WiFi.

What could be of importance: I just saw that the WiFi network does have two access points.

OK, we now know that your device uses ath5k as the driver.

Your information is hard to understand. Does the wireless on this computer work
anywhere?

Does your statement that the wifi network has two access points come from scan
output, or what do you mean? If ‘sudo /usr/sbin/iwlist scan’ shows your AP, then
you might have a configuration problem. The other possibility is that the AP is
incompatible with ath5k, but I doubt that.

Yes, all the other places I work with WiFi (not much, about five) I can work with WiFi. With my netbook (an Aspire one) I could work with WiFi when openSUSE 11.3 was installed on it. After the upgrade from 11.3 to 11.4 a scan with knetworkmanager shows nothing.

I used my Nokia to get info about the network that I did not see. This showed that there were two access points. I am now working without a problem (on another location) with WiFI. When I do a scan here, I see that there is only one access point.

I just did an iwscan list. This gives:

lo Interface doesn’t support scanning.

eth0 Interface doesn’t support scanning.

wlan0 Interface doesn’t support scanning : Device or resource busy

I did the same when I was on the location where it did not work, and if I remember well I had the same output.

When you get the “Device or resource busy” message, that means that
NetworkManager is doing a scan at that time. If you wait a few seconds, you
should be able to resubmit the scan and get results.

Please post the scan information for the site that is giving you problems.
