I'm having trouble getting a consistent wifi connection on my Rpi/Xbian. It seems to connect fine while booting. The time is usually displayed correctly, but by the time it takes to check system info the connection is dropped and no IP is displayed. If I leave the system info screen up it will periodically connect, show an IP, and drop again.

I've had this RPi for over a year and recently upgraded from XBian Alpha 1 to Beta 2. I've had some problems before, but this is nearly constant.

Edit: Tried directly plugging in the dongle as in this thread. It had no effect.

Where do I start with troubleshooting this?

what kind of dongle it is ?

and what is your wifi network configuration ? a/g/n/b free/wpa/wep/wpa2 ?

It's an iogear that i bought along with the pi. My network is wpa2 and I believe b/g/n.

?

It just says "Interface wlan0 already configured". Am I inputting it wrong? I typed "sudo ifup -v wlan0"

Also, wifi didn't connect at all for those first two files. I can copy them again from a boot that actually connected once if need be.

ifup -v wlan0 still returned the same.

I have tried with the dongle directly connected and in a powered hub, with and without my bluetooth keyboard/mouse.

I'm considering reinstalling or downgrading.

and why you have not considered upgrading ?

you have old kernel.

I didn't know I could. I'm running the latest image, how do I upgrade the kernel?

image you created your system from is not important. it's purpose is to deliver a running system to your hardware.

usually you would not need image/re-flash ever again.

Flashed, didn't help. Updated, didn't help. etho0 works. I was starting to think it's the wifi dongle, but I was able to plug that into my laptop and use it.

Edit..... As I was typing this I plugged the dongle back into the (pi's) usb hub and it's working again. I let it run for 10 minutes and restarted it twice and I'm still good. So strange.
