Blind Network Manager
Please attach the output of nm-tool if you feel like KNetworkManager does not show all available networks. Does it show more networks then KNetworkManager? Please attach the output of nm-tool if you feel like KNetworkManager does not show all available networks. Does it show more networks then KNetworkManager? *** Bug 417335 has been marked as a duplicate of this bug. *** Here is a log of "iwlist wlan0 scan ; nm-tool ; iwlist wlan0 scan" as you can see, at this point "iwlist wlan0 scan" is not showing networks (well initially only one" but NetworkManager is. I am really suspicious that the iwl4965 may also be causing problems here:

Could you please try to disable hw scanning: rmmod iwl4965 modprobe iwl4965 disable_hw_scan=1 (you may need to restart both NetworkManager and knetworkmanager afterwards) and report whether it changes anything? It seems to work much more reliably with "disable_hw_scan=1". How can I make this the default setting? Could you elaborate on that, please? Did the problem occur after setting disable_hw_scan? You can set it permanently by adding the following line to /etc/modprobe.conf.local: options iwl4965 disable_hw_scan=1 Sorry, that was stupid question. It has been so long since I had to manaually configure a driver's options that I had forgotten how! With "disable_hw_scan=1" the number of visible access points displayed by nm-tool, iwlist wlan0 scan, and knetworkmanager match. That was rarely the case previously. On a related note, while "iwlist wlan0 scan" shows the number of visible access points, nm-tool and knetworkmanager both force your to manually count the number in the list. It would be nice if there was a count somewhere.. (In reply to comment #10 from Peter Nixon) > With "disable_hw_scan=1" the number of visible access points displayed by > nm-tool, iwlist wlan0 scan, and knetworkmanager match. That was rarely the case > previously. Sorry, this is not possible. I think it's just a coincidence. Could you please test that for a longer time? Unfortunately I think you are correct. At present nm-tool, iwlist wlan0 scan, and knetworkmanager all report different wireless networks visable. Created attachment 249802 [details]
Deaf NetworkManager
Thanks for confirming. So this is the same issue as bug 406635. *** This bug has been marked as a duplicate of bug 406635 *** |
NetworkManager in openSUSE 11.0 is very unreliable at displaying available wifi networks. Particularly if you have been (or are) connected to an SSID, and then want to connect to another, it rarely displays all the available networks in the vicinity. (I work for a wifi AP vendor so connecting and disconnecting from various wifi networks is something I do continually all day) I did not have this unreliability with openSUSE 10.3. This problem even occurs if you have been disconnected from wifi for a while (running on ethernet) and then want to connect back to wifi. Below is the output of "iwlist wlan0 scan" displaying 15 wifi networks. Attached is a screenshot of NetworkManager at the same moment displaying 4 wifi networks!!! wlan0 Scan completed : Cell 01 - Address: 00:12:BF:2B:F7:01 ESSID:"sadiko_testingg" Mode:Master Channel:1 Frequency:2.412 GHz (Channel 1) Quality=72/100 Signal level=-62 dBm Noise level=-127 dBm Encryption key:off Bit Rates:1 Mb/s;
