I need some help guys. I have been having an issue with my wifi connection, it will work a while, and then I can not access any web pages, says I can not connect. If I shut off wifi, even when working, I can not find ANY networks after that. What is going on? Any one know how to fix it?
iMac, OS X Yosemite (10.10.3)
One of the first things to try is resetting your modem and router. Then restart your computer in Safe Mode (hold down the Shift key until it starts in Safe Mode) and then restart normally. The Safe Mode startup will clear some caches.
Let us know if this helps and it also may help you to read: http://osxdaily.com/2015/01/30/os-x-10-10-2-yosemite-wi-fi-problems/
