I have spent too many hours trying to find why my wireless EDMAX chip isn't working, my pi recognizes it and I tried this whole thing:

I keep on getting stuck in terms of there is a install-rtl8188cus.sh.1 in my /home/pi but I still cannot get it to execute?
I am not sure why this isn't working, can anyone please help me!?
Thank you so much!

I believe that all recent versions of raspbian have the requirements to use that wifi dongle installed by default and it should just work. try using the wifi config program.
as for why the script isn't working did you

So initially it said the operation was not permitted, then I used sudo.
The command clearly went through, but it still does not work?
Thank you so much for the reply, I am really lost and would love to get this thing to work!

Don't follow any guides more than a couple of months old for the Pi, the software is being developed at such a rate as to render them obsolete in very short order. The Edimax EW-7811UN aka the RTL8188CUS has worked out of the Box with Raspdian since about October 2012. Plug it in and configure it with the Desktop Wifi utility or tweak /etc/network/interfaces and/or wpa-supplicant. Theres a good chance you'll stop it working by installing a driver intended for an old version.

Is there a way to reset the settings? I also tried using the interface given and that didn't work either. Please help!
Thanks.

I'd do the obvious and reflash the SD card with the latest image. Or better still. Get a new SD card and do it on that.

Good advice to start with a fresh image and go from there. Part of the secret with wifi is getting the proper encryption, SSID, and keys set up. I have that same adapter and set mine up manually. For new users I recommend doing "startx" to get to the desktop and then using the wireless configuration tool.

Is startx for Linux?
Thanks
