I just got an arduino yun, and went through all the onboard wifi setup; However rarely does the wifi ever work, and when it does it only works for a while then stops working (Yun does not show up in ports menu in arduino). I'm powering the yun with a 9v battery hooked up to a 5v regulator that supplies the arduino through the Vin port with 5v. If anyone has had this issue or knows a possible solution please help. Thanks.
After you configure wifi and reboot, does the wifi led start blinking after a minute or so? If so and if it keeps on blinking, then after about 60 seconds the yun will reboot and get back to access point mode.
Access the webpanel: it will contain a text area with some cryptic debugging information you should attach to the forum
That's pretty much the same issue I run about: IF YOU POWER THROUGH VIN A REGULATED 5V THE WIFI WILL NOT WORK. I am not even able to reset it to access point mode, so the board for me is basically unusable (see my earlier post about Power question). It is a bit incredible for me that this issue is not checked!

Well, I would have to disagree, I run my Yun by supplying regulated +5V to the Vin pin, and it is using WiFi for communication.
I wonder if your 5V supply can supply enough current?
Yes i was thinking that would be a possibility. How are you powering your 5V?
I am using a 12V wall plug and going through a 5v switching regulator which is pin compatible with 7805. I have 22 uF capacitors on input and output of the regulator. The output of the regulator is connected to the Vin pin. I use the 5V out of the Yun to power my DS18B20 sensors. This and other stuff is on a proto shield.
Thanks, bjarne! Finally a piece of information. It turns out that my power supply module is "buggy". (The voltage dropped from 4.96 to 4.7 - 4.8 V with the board powered - I thought this is reasonable, mainly because it drops to this level also when powered from USB...I put a 22uF capacitor to its out, but did not help.) I'll try to get/ or make a quality power supply.
Again, thanks for your post. (Sometimes you have to be a bit harsh to get some reaction...
Cheers,
You are welcome, we are here to help each other !
I looked at the link in your other post to the power supply, and I couldn't find any specs for its current capabilities.
