Issue setting up Wi-Fi on Raspberry Pi 2 (Model B)

Tue Mar 29, 2016 4:42 pm

Yesterday, after having my Raspberry Pi sitting in a drawer for close to a month, I decided to finally set it up.
Unfortunately, the screen which I bought for it arrived broken, so I am having to do everything through my laptop and Mobaxterm.

When I set up the initial internet connection using an ethernet cable (I was going to borrow someones, but then I found a humongous purple one from a long time ago), it set up fine.
Unfortunately, its setting up the wifi setup which gives me the issue.(For what it's worth, my Wifi adapter is an Edimax EW-7811Un)

I tried several methods of setting it up, but none of them have helped.

First, I followed this guide to set it up using text editing, I triple checked my SSID and Password, but to no avail.

Then, I decided to try the Wifi setup offered by Raspberry Pi (because I didn't think of it right away), but it didn't prove useful. Left clicking it told me that no wireless interfaces were found, and it did not show me my router,right clicking it and click settings did not seem to help either, as SSID did not show my router.

Finally, I finally decided to try this method, but that didn't make any improvements over what I had already.

So as it stands now, this is what I get when I check the wlan0 setup using ifconfig -a.

As you can tell, it does not have an IP address, but a mixture of letters and numbers.

After looking for a while today, I found numerous threads on various forums, saying that if the Router security is WEP, then it may not work. I set up my phone temporarily to create a WPA2 hotspot, and my Pi connected perfectly. However, that is not ideal for me naturally.

My questions are as follows:

Why would the adapter connect to my router perfectly when used on other devices, but not when used for my Pi?

Is there any solution which would let me connect my Pi to WEP (since for various reasons I cannot change the security of the router at this time?

Is there a different solution to my issue which does not involve changing my router security?

What model wifi adapter are you using with the Pi? There are a few that do not work as an access point, so if you are using the Pi as a hotspot, then nothing can connect to it. There is a short list at the top of this link.

That is just the first thing I would check. I'm trying to setup the Pi3 as a wifi access point, but haven't been successful so far, I think I just don't have the correct .conf settings though.
