cfg80211: failed to add phy80211 symlink to netdev

I am seeing this message upon booting:

$ dmesg | grep netdev
[    5.173793] cfg80211: failed to add phy80211 symlink to netdev!

Does anyone know what this means?

As additional background, I am using an Intel ipw2100 wireless NIC, and I have disabled IPv6 in the /etc/modprobe.d/modprobe.conf file by adding:

# disable autoload of ipv6
alias net-pf-10 off

Please note that even when the above is commented, I still see the netdev message upon reboot.

Any help would be appreciated. Thanks!

After upgrading my system today, I am also seeing this message during boot onscreen and in my dmesg log, although I don't know what this means.  Could it be something to do with incorrect udev rules?

My wireless network connect is working, but the message seems to suggest that something isn't being configured correctly.

My wireless network adapter as reported by lspci is an "Intel Corporation PRO/Wireless 2200BG [Calexico2] Network Connection (rev 05)."

I see this on Thinkpad R51, which uses ipw2200. Lost the URL, but read somewhere that it's actually a bug (basically just a debug message). Wireless works fine, so I've decided to just live with it, until a fix comes along.

The same here. I just updated my system.
Wireless adapter is Intel PRO/Wireless 2200BG.

Wireless seems working. Well, please, update us if a solution is found. I hate such kind of warning messages, while loading my system.

Please don't take this the wrong way, it's meant in a playful tone...

dir2cas, you must have a really, really perfect life if you can afford experiencing hate towards harmless warning messages during boot.

Re: cfg80211: failed to add phy80211 symlink to netdev

My network card is also Intel PRO/Wireless 2200BG.
This message is really annoying since it will interrupt the login screen.

According to here http://ask.fedoraproject.org/question/7 … -to-netdev
A bug should be file to Kernel dev.

I thought it was a deteriating h/w issue, until today FW ipw2200 failed to load after udev upgrade.
Obviously this problem is not settlted, on the contrary it is getting more critical.

The udev thing is this: https://bbs.archlinux.org/viewtopic.php?id=134012

The other issue described in this thread: Ignore it. The symlink is not needed for the operation of the card.

$ dmesg | grep netdev

cfg80211: failed to add phy80211 symlink to netdev!

and in addition

I did downgrade to 184-2 version of systemd-tools (udev included in systemd-tools package ) but isn't help me.
Also I post this bug on https://bugs.archlinux.org/task/31168

Re: cfg80211: failed to add phy80211 symlink to netdev

The symlink error, like I said, ignore it.

The other thing, well, maybe the timeout patch Arch is using no longer works. Give this a try:

echo "blacklist ipw2200" >> /etc/modprobe.d/blacklist.conf
echo "ipw2200" >> /etc/modules-load.d/ipw2200.conf

Re: cfg80211: failed to add phy80211 symlink to netdev

I do it and reboot system, module is not load and not show wlan interface, I checked it : rmmod ipw2200, and have blank.
When I modprobe ipw 2200 I take again:

 Aug 20 20:47:26 localhost kernel: [    6.870167] cfg80211: failed to add phy80211 symlink to netdev! 

and iwconfig shows my WLAN interface.
Its works but is not stable. Error is still present.
Thank you.
Who have any idea?

Re: cfg80211: failed to add phy80211 symlink to netdev

Reboot system and then post the output of dmesg.

And what exactly does "Its works but is not stable" mean? That's way too vague. What kind of network are you connecting to (wep, wpa, not encrypted), what exactly is the problem?
