Raspberry Pi Forums

Hello,

I realise this was a while ago, so not sure if still active! However I am having exactly the same problem of not being able to retrieve my wlan0 ip address and I don't have the possibility of getting a new WIFI adapter as I am doing an exhibition tonight using this!

I am using ThePiHut wifi adapter (http://thepihut.com/products/usb-wifi-a ... spberry-pi).
I am running Occidentals, as I am creating an adaptation of Adafruits thermal twitter printer.
I am connecting to the pi through ssh and it is connected to my router.

I need it to not be connecting using the ethernet and instead using the wifi but cannot find wifi's ip!

Any help would be much apreciated as the show starts tonight at 18.30!

Thanks,

RJ

Hi,

Hi Guys/Girls;

Brand new to RPi and am having some issues with connecting to internet over wireless adapter. Works great with ethernet and the lights do come on on my comfast Cf-wu810n wireless dongle when plugged in but I can not connect and shows "Not associated". I can see the card and the realtek 8188 driver looks to be installed correctly and interface and supplicant files are cut and pasted in as explained in this post but when i attept to connect to visible network it shows all networks in view with "0" signal strength. So it sees the networks around me but it wint connect toany and list all networks with "no signal.
Also the network gui in raspian that shows the network status in upper right corner wlan0 not associated. When i left click on the icon it says "No wireless interfaces found". So instead if a drop diwn with all the wireless networks it says that. The list of wireless networks come up when i plug in the ethernet cord though. Please help.

Hello;

Looking for help with my wifi setup as well. Followed most of the instructions in this post but still can't get wifi adapter working. When i highlight the network icon in upper left of raspbian it says "Not Associated" and when i left click on the icon it indicates there are "no wireless interfaces found"

Here are a few screens:

/etc/network/interfaces shows the following:

Hi there,

Thanks for your reply. Apologies as it turned out it was a rather stupid error of putting the wifi password in rather than the proper ssid password! So I got the wifi up and running fine in the end. I did however preceded to completely burn out my raspberry Pi by running too much power through its pins!

Think I need some more practice before using this stuff AFK!
