[SOLVED] Wifi works, doesn't find network

[Ichalex]

Hello there!

I just installed Xbian and updated to 2.1. I also just got an edimax wifi dongle. It works flawlessly with openelec. But Xbian does not find my network, though it finds any other network in the house. I tried entering the ssid manually, but it doesn't connect. My router is a dlink dir-600, it's encrypted with wpa-psk tkip/aes mixed and the passcode consist of numbers and letters. Please help, as I really like Xbian and don't want to switch

What's the output of (SSH into your raspberry pi and execute: http://xbian.org/getting-started/install-and-connect/#ssh )

Code:

sudo iwlist wlan0 scan

It finds several networks, I can't scroll high enough in putty to see everyone of them, but I guess it's the same as in Xbian-config

I doubt it's a OS issue but rather a network issue. The command Koenkk suggested is the core command for scanning for networks. Should be the same for OE and XBian.

Well OpenELEC connected successfully, don't know why, and I can't reproduce it. Every other wifi device works. And Xbian finds 14 different networks in the house/street but not mine? It's not that the SSID is hidden or something.

It has to be a kernel issue.

attached a screenshot from xbian-config. it seems to work, but as i said, my router won't show up

[rikardo1979]

just a wild guess, but maybe the ssid name or lenght or special symbols ?

[Ichalex]

It works. I disabled the auto channel option on the router. I set it to channel 12, didn't work. Set it to channel 10, works. Interesting

[Ichalex]

Well it kind of loses connection pretty often, but at least I kind find my network now

If your near enough to detect 14 AP's your issue is most likely interference.

Well, iPad, smartphone, and 3 PCs work flawlessly. And it's definitly a software bug, as when I enter the PSK in the GUI config (not the ssh) it sometimes works, an then not.

When connected, whats the output of

Code:

sudo iwconfig wlan0

[Ichalex]

Code:

Edit: aaand it's gone. We'll not entirely, airplay still worked. but theres no internet access. but thats only an issue on the rpi, not on the other devices. here's the network status:



Edit2: I turned off my tv, and heard music over AirPlay. Then it stopped. I turned on the TV to check network status and it says busy on MAC address and Internet connection. Then I wait, and it gets a Mac adress, then it's busy again, as I'm writing this it's entirely connected again. Maybe it's because of the CEC of my tv, that sends Xbian into suspend? I know that on openelec, you can change the CEC behavior of Xbian. I will try to disable CEC and try again.


Edit3: disabled CEC, so far so good. Discovered the CEC config screen, it was set to ignore when turning of the TV. Strange. Now I enabled CEC...see how it goes

[Ichalex]

Ok, so it keeps losing the connection/being busy. For example I played a song over AirPlay, TV off (shouldn't have an impact I guess) and no power saving. Then stopped playing the song, did some other things. Then wanted to listen again, now I can select Xbian as AirPlay client but nothing happens. Checked network status: busy. No Internet.


Edit: ok, now After losing the Connection again. Airplay didn't work, connection was lost for real. Rebooted, nothing. Went to Xbian config via the gui, no networks show up at all. Trying with ssh, my Network Shows up, but connecting falls. Help!
