[SOLVED] WiFi issues with NetworkManager 0.9.4

After upgrading to NM 0.9.4, wifi stopped working. I have a Broadcom chip. Here's the lspci output:

05:00.0 Network controller: Broadcom Corporation BCM43225 802.11b/g/n (rev 01)

Here's a log excerpt:

Apr 23 21:03:35 localhost NetworkManager[10841]: <info> (wlan0): driver 'wl' does not support carrier detection.
Apr 23 21:03:35 localhost NetworkManager[10841]: <error> [1335207815.523410] [nm-device-ethernet.c:456] real_update_permanent_hw_address(): (wlan0): unable to read permanent MAC address (error 0)

Using the proprietary wl driver, wlan0 interface is seen as wired. With the drivers included in the kernel (brcmfmac), it's not seen at all.
rfkill output is blank, don't know why...
Downgrading to 0.9.2 "solves" the issue.

Any hint?
Thanks

I also found my wireless failed after upgrading to 0.9.4 - this is on a machine with ipw2200 - downgrading to 0.9.2 got wireless working again.

Re: [SOLVED] WiFi issues with NetworkManager 0.9.4

I've just tried appending ipv6.disable=1 to kernel line. No luck...

Re: [SOLVED] WiFi issues with NetworkManager 0.9.4

Disabling ipv6 did not help me get nm 0.9.4 working either.  In my messages log I have the following:

I then downgraded nm back to 0.9.2 and restarted NM and it works fine again.

This surely is a bug in NM?   I will look to see if there are any bug reports - perhaps upstream?

NM 0.9.4.0-4 is now working for me.

Re: [SOLVED] WiFi issues with NetworkManager 0.9.4

It is working for me too but the KDE panel display for the wireless connection fails to show the signal strength.

Re: [SOLVED] WiFi issues with NetworkManager 0.9.4

I'll mark it solved, since the problem is gone. I cannot reproduce your new issue, since I'm not using KDE and it looks like it is related to kdeplasma-applets-networkmanagement.
Maybe you should open another thread, as you did filing a new bug.

Re: [SOLVED] WiFi issues with NetworkManager 0.9.4

OK thanks - I labelled it as a networkmanager issue but if this is a problem with kdeplasma-applets-networkmanagement then I guess that should be added to my bug report?

Re: [SOLVED] WiFi issues with NetworkManager 0.9.4

Try installing network-manager-applet, and see if the signal strength is correctly shown. If so, it's likely it is a kdeplasma-applets-networkmanagement issue. If not, perhaps it's worth digging a little bit more, to see if the bug is related to NetworkManager (you maybe want to take a peek to wicd, then...) or to the driver. Since you state iwconfig correctly detects the signal, I think the latter is less likely.

Re: [SOLVED] WiFi issues with NetworkManager 0.9.4

I did install network-manager-applet but this also shows no signal - it seems maybe it is neither kdeplasma-applets-networkmanagement, nor network-manager-applet at fault. So it seems that the connection is fine but the display icon on the panel or the link between the data about the connection held by networkmanager and the display is not set up correctly - however it is not a problem with all wireless connections and only (for me) my machine with ipw2200 - the same setup on another machine using the iwlwifi driver is fine and does show the correct strong signal strength!
