unable to connect to wifi on iphone 4s
So long story short, I recently installed ios 8.2 on my iphone 4s and for some unknown reason when I try to connect to a wifi network it is telling me "unable to join". I have tried trouble shooting the issue by resetting my network settings which has not fixed the problem either. What makes this even more frustrating is the fact that prior to installing the alleged "update" my phone was working perfectly fine. If anybody can offer some solutions that would be great! Thank you...
