Okay, so I seriously need help, I'm having trouble with my wifi. Everything works just fine except for the wifi, and I'm tired of using my ethernet cable. It's driving my family nuts.
I obviously have a Dell Inspiron N5110 that I've had since December of 2011.
I successfully installed Yosemite on my computer and updated it to Developer Preview 7. A while back, I ordered a Dell Wireless 1702 card off of Amazon, and it is Atheros AR5B95, which I heard was compatible. I installed it onto my computer, and found a kext off the internet for it. However, it will not identify ANY network. I cannot set up wifi manually, and it will just keep saying it is searching for a network. The icon appears on my menu bar is there, but again no networks will detect.
Did I put it in wrong? Do I need to re-plug in the antenna cables? What kext did you use for your wifi to work? What should I do? Please help me, I have researched a lot and nothing has worked so far.
