I think you just click on the WiFi icon, top right of your screen and it displays a list of WiFi's it can find.
Click on the one you want and enter the password.

He says it is from Element 14. According to the box for my WiFi dongle from Element 14, they are Official Pi suppliers

Your dongle should work out of the box.
What is the output of

Code: Select all

ifconfig
Does the red power led stay on at all times; no blinking?

Try

Code: Select all

sudo iwlist wlan0 scan
to see if you can see any access points.

BTW: how is your access point set up?
Do you know the channel, security settings (WEP / WPA) and if it's hidden r not?

Thanks for your reply.
I found a tutorial that worked.
just played around with the setting on the command line with a few extra lines.

Simple answer: DON'T, change your network to use WPA or WPA2.

Complex answer:

Code: Select all

     ctrl_interface=/var/run/wpa_supplicant
     ctrl_interface_group=wheel
     network={
	     ssid="example"
	     scan_ssid=1
	     key_mgmt=NONE
	     wep_tx_keyidx=0
	     # hex keys denoted without quotes
	     wep_key0=42FEEDDEAFBABEDEAFBEEFAA55
	     # ASCII keys denoted with quotes.
	     wep_key1="FreeBSDr0cks!"
     }
you really don't want to use WEP because you may as well set your network as open for all the security you get with WEP, it takes about five minutes to crack a WEP network.

I faced the same problem a few months back... i was not able to get my wifi up after searching on internet and a few posts on the forum. I used to find the network but was not able to connect to it. It said that the password was too short.
This is not the best option but if you are really determined to setup the wifi try using Ubuntu MATE. It automatically sets up your wifi no errors... and has a better GUI, although i learned the basics of linux on raspbian. You can give it a try. :)
