[FIXED] Establishing WiFi with Edimax EW-7612UAn V2

Help and Support Help

Hi,

I just got me a Rasperry Pi today (Hifiberry DAC ordered too) and I’m having issues getting WiFi to work.

Setup:

I have installed Volumio on the SD according to instructions provided at http://volumio.org/download/, connected the ethernet cable, SD and USB WiFi stick and then power cable. The Pi boots and I can access it perfectly fine via http://volumio.local. Next I added my WiFi login details to http://volumio.local/net-config.php, saved the changes, unplugged the ethernet cable, and … tadaa … nothing happens.

Should I reboot first?
Should I update any drivers (and how)?

Any hints for resolving this are much appreciated. Please note I am completely new to the Raspberry.

Thanks for your help

Okay, finally got it working by activating SSID broadcast and following these instructions http://www.raspyfi.com/wi-fi-on-raspberry-pi-a-simple-guide/.

wI-FI config needs a reboot…

I have now clean installed 1.1 and wanted to try setting up WiFi with your suggested reboot, but still I am unable to connect via Wifi.

In preparation I made the SSID visible, booted the freshly installed Pi with the Wi-Fi USB stick and ethernet cable plugged and accessed via volumio.local/. Next I used the Power Off button, waited until the Pi was shut down, disconnected the ethernet cable and rebooted the Pi but I am unable to access the Pi via WiFi

Am I missing something? Does making the SSID visible have any effect? Could it be my rather long WiFi password consisting of various symbols (though it seemed to work using the method described at raspyfi.com/wi-fi-on-raspber … ple-guide/)

Thanks in advance for your help.

Yeah, making SSID visible could have messed up something… Or maybe is just the pw you’re using that is not compatible (issue of Volumio…).
To check that, reflash Volumio, connect with Ui to wi-fi, save. Then connect via ssh and see if wlan0 gets an IP with

ifconfig -a

You can also paste it here for convenience…

Hi michelangelo, I reflashed the SD and proceeded like you suggested, here is what I get:

wlan0 Link encap:Ethernet HWaddr 65:1f:02:ae:bd:d6 BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)

In this test the SSID was hidden and I had entered my 62 characters long password which consists of all kind of small and capital letters, numbers and symbols.

Guess the problem is your wi-fi configuration. I mean, Volumio has still problems with WEP and strange characters in pw. I’ll try to fix this in the future. For now I suggest you to use the wicd-curses workaround of RaspyFi… With that you got it working?

I finally got it working following the instructions provided at http://www.dafinga.net/2013/01/how-to-setup-raspberry-pi-with-hidden.html.

It seems some of the characters I used in my PW were not accepted, not sure which (>, <, $) it was but after I had removed these from the PW I was able to create the PSK and and set up the Rasperry with a hidden SSID.

So the conclusion could be, if

wpa_passphrase "Wifi-SSID" "Wifi-PASSWORD" errors your PW is likely to not work due to special characters used in the PW.

Thanks for your help!
