2.6.39.1-1 breaks wireless

After the upgrade, I couldn't obtain even an open wireless connection when done manually. Anyone else having this problem? I had to revert back to 2.6.38 to get it back.

You may want to provide some details on your system.

Here's my hwinfo | grep wireless output:

Did you check your logs to see what might have failed?

After upgrade to 2.6.39.1-1, I can sometimes connect to wireless, sometimes not. Sometimes when connected, wireless will drop.

Re: 2.6.39.1-1 breaks wireless

Have you changed your rc.conf to the new format?

What app are you using for your wireless network management?

Re: 2.6.39.1-1 breaks wireless

I had this same problem.  My laptop is a Dell Latitude D610.  I have a built-in Network controller: Intel Corporation PRO/Wireless 2200BG - using the driver ipw2200, and connecting using wicd.  My rc.conf file is configured per the latest instructions for networking.  Wicd had never failed me until I upgraded my kernel to kernel26 2.6.39.1-1.

After that, I had no more wireless, no matter what I did.  I turned off the onboard wireless card and plugged in an Atheros pcmcia card - ath5k.  Still nothing.  The system could not see it at all.  Wicd no longer worked either.

So - I installed wifi-radar and configured it, and voila! The Atheros card showed up and connected.  So I removed the pcmcia card and reenabled my onboard Intel wireless card and tried wifi-radar again.  Bingo - it worked.

So in the end - I switched to netcfg - set up the appropriate profiles - set it to display a menu (wired or wireless) at boot time - and everything has worked perfect since.

I have no technical explanation for why all this changed, but my experiential evidence is clear.  Using netcfg and it's profiles, properly set up, works better than anything else in arch for me.  Perhaps it might for you guys too.  All the detailed instructions are on the wiki and easy to follow.
