nm-applet shows wifi spots but do not connect

DrMonkey · 2010-12-09 14:01:49

Hi,

I did a system upgrade late last night, back from sport after an exhausting day, pacman said stuffs (a file change I think) about NetworkManager, I said "ho, whatever", shutdown the computer...

And now, nm-applet starts, shows wifi spots, but when I try to select one, it does not connect to it, despite other computers can...Despite reading on the forum, I'm clueless about where to begin, out of "pacman said stuffs about things for NetworkManager". Yes, I am lame All worked fine before, so we can safely assume the upgrade is at the core of the mystery.

Versions of things:
- Kernel 2.6.36 (Nov 24 2010 i686)
- NetworkManager 0.8.2
- login with Slim, windows with Fluxbox

[PS] Is there a place where Pacman keeps its messages for the exhausted dudes who were too neglectful to read them at first ?

/var/log/pacman.log

Are you using the [testing] repository?

I do not use [testing]. After a look at /var/log/pacman.log, the problem might imply a switch from
- NetworkManager 0.8.1-2 to 0.8.3-0.20101130
- nm-applet 0.8.1-2 to 0.8.2-2

Actually, which kind of file I might look to understand what happens, why Wifi spots are detected, but the connection does not happens ?

Try to connect and then type dmesg in the terminal.

DrMonkey · 2010-12-12 01:56:49

dmesg does not display anything new when I try to connect.

jdn06 · 2010-12-12 08:20:30

And what does iwconfig say after the connection attempt?

Before and after connection attempt, same thing:
wlan 0 IEEE 802.11bg ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=20 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Power Management:off

Are you sure it shows actually wifi spots?
Try a "iwlist wlan0 scan"

Try to run nm-applet as root.

sudo nm-applet

If you can connect as root, we have the same problem.

DrMonkey · 2010-12-14 02:21:07

@jdn06: iwlist wlan0 scan returns all the wifi spot around, with the same details (signal strength, address, etc) reported by an other computer I have.

@ammon: Indeed ! If nm-applet runs as root, then all works fine. Before that upgrade, nm-applet worked as a normal user, but required me to perform the "Mad Hater Trick" (see https://bbs.archlinux.org/viewtopic.php?pid=501593) I guess that trick need an update.

ammon · 2010-12-14 14:52:47

Yes, the same thing happenede to me after update. Im using wicd now.
Something is wrong with dbus or policykit configuration, I cant figure out what.

Indeed, this is a new bug with networkmanager after the lastest update. Here's the link to the bug report:
https://bugs.archlinux.org/task/22149

I have to connect manually via command line for now.

iwconfig wlan0 essid "someNetwork" key FOO123BAR345
dhcpcd -k wlan0; dhcpcd wlan0

That might be a little different for you though...

trusktr · 2011-01-14 17:40:10

SOLVED: I simply had to delete the wireless profile then reconnect to it and it worked; creating an all new profile.

Does this work for you?
Should I leave that bug report open DrMonkey?
