Nevermind. This issue is not resolved. We still get dropped connections randomly often without error messages on either network we've tried.

It's so frustrating. It is making me consider giving up the gumstix platform entirely as our client is likely going to start losing confidence in our project if it can't even maintain a simple wifi connection over night without randomly turning off. 

The wifi light just turns off, iwconfig thinks it is still up.

Hi everyone.

I can confirm two things:
  1. When we set up a ping script to hit our server every 60 minutes (either as script or in our voip application) we don't have the connection issue.
  2. When we connected to a different network (+WEP, different hardware) we did not have this issue.
So it is likely related to the routing hardware which is a shame. Ours is relatively new and I have no idea why there is an issue.

I'm not sure what to suggest for you to try, but don't rule out WIFI infrastructure problems just because the connection works with Ubuntu. Here at my office I have multiple wireless networks I can (attempt to) connect to, but not all work with all clients. For example, we have 1 network here that uses WPA2 that I have no problem connecting to with Ubuntu and my MacBook, but I can't connect with my Overo and my wife can't connect with her older MacBook Pro, and I've heard others have issues connecting with Windows. On this particular network my experiences are similar to yours in that I am sometimes able to connect but can only get a packet or 2 out before I'm disconnected. We have another network here that uses the same config as the 'bad' network with the exception of the essid and the hardware (the 'bad' one is cisco and the better one is an apple airport) and I have no problems connecting to it with any hardware. I've never had any problems connecting to an open (no WEP/WPA/etc) network.

HTH,
Chris

Thanks Chris. You're probably right in that it is a combo of our AP and the overo.

I can tell you that we only have this one router at work... but we use it with our laptops (running Ubuntu) with no problems.

Do you suggest trying anything on the router's settings that may help something?

Sorry to hear you're still having troubles. 

What have you done to troubleshoot your wireless environment/setup as being the problem as opposed to the overo? Wireless networks and configs can be really picky... REALLY picky. 

Specifically:
- Is the behavior the same on an "open" network with no WEP/WPA/etc?
- Have you tried using a different AP to connect to?
- Are there any clues in /var/log/messages when the link goes down?

Newest image still has this problem. It's infuriating.

Is there any image for the overo that lets me connect to wifi and not get disconnected? It's worth mentioning that I believe the wifi worked when we were booting off of the SD card, but now that we've flashed it it isn't working.

Still getting this one:
cfg80211: Calling CRDA to update world regulatory domain

Thanks for your feedback! So far I have had no luck with newer images. I am beginning to suspect the AP hardware but your experience has me wondering now if it is indeed a software thing.

Do you have an old image that worked for you? I'd love to try it.

thanks,
Blaine

Dear Blaine,
I have the same problems as you are describing.

After 2 - 3 minutes the wifi disconnects, you see a lot of blue LED activity
and about 2 out of three times the connection is re-established (steady blue
LED).
This is also accompanied by a cfg80211: World regulatory domain message.
I'm pretty sure that problems are associated with the cfg80211. Though these
messages may be generated by the disconnect/reconnect.
Previous kernel versions prior to 2.6.39 didn't produce any cfg80211
messages and the wifi interface never failed using the same hardware and
wifi infrastructure.
I'm in New Zealand with a different set of channels so the wifi interface
has to change from the default US so that might be a problem.
There have been various post about the cfg80211 messages 'newer kernels have
been fixed' and 'Steve's tree needs a patch for this' but I've not had
stable wifi for any of my images since I moved up to 2.6.39 and 3.0.0.
By the way my images are based on console images and do not have
Network-Manager installed.

Cheers Mike.
