Wi-Fi TL-WN722N - João Barradas - 13th Nov, 2013 07:33 PM
Hey. I've been trying to get wifi through this dongle (tl-wn722n).
Pi recognizes it as it blinks the green light. Although, when scanning WLAN, nothing returns.
I also wrote some lines I found online in wpa_supplicant.conf and /etc/network/interfaces .
But still nothing happens.
What am I missing? What can I try?
Thanks

this are some basic commands to check what is going on:
Code:
ifconfig - (wlanx should be listed)
iwlist wlanx scanning - should show latest scanning results
iwconfig wlanx - will show some actual parameters about wlanx current configyou didn't write your XBian version so hard to guess more, but there were some issues with this on Beta1X. Some were dependent on actual dongle type / brand, others have been fixed some weeks ago in Beta2.

Xbian version is Beta 1.1.
I'm at work now, but later tonight I will test those commands and post the result here.
Where it has "wlanx" the "x" is actually the "x" or is it a number?

Yes, sorry.
x is index - wifi adapters being called wlan + number

According to USB_Wi-Fi_Adapters this requires a USB powered hub - are you using one?

I'm using a USB Hub. Don't know if it's powered or not. But the adapter gets power, because I see it blinking the green light. Couldn't this be enough?
I'm using one of these: http://www.ebay.co.uk/itm/Mini-Clear-Blue-4-Port-USB-2-0-Hub-w-LED-Indicator-/390610210537?pt=UK_Computing_USB_Cables&hash=item5af22ecee9

That HUB is not externally powered it is powered directly off of the RPi which only outputs max 100ma. If you have poor reception then it has to work harder and thus use more "power". See Thread
If you have a external powered hub, can you try that.
Also try moving the RPi as close as possible to the router and see if that improves it.
Also can you post the output of dmesg -> See Please read before you post - A link is in my signature.
