Trouble with wifi in macbook air and ipad2
My macbook air and ipad 2 can't connect to my wifi, but they can connect to other wifi networks. Also, my imac can connect to my wifi.
My wifi network seems to be working fine, and I can connect to it using my imac, but when I try to connect using my macbook air or my ipad 2, my wifi is detected and can connect to it but when I open my web browser or use apps that need internet, the apps and browsers act like if there was no internet at all. If I do the same with my imac, then nothing strange happens, everything works perfectly. My macbook air is a 11 inches, early 2014 with os x Yosemite 10.10.3 and my imac is of 21.5 inches late 2012 with version 10.9.5 I don't know think is because of the os x Yosemite because I just update my macbook air, thinking that was the problem, so I couldn't connect to my wifi network with my macbook air even when I didn't have it updated. Can someone help me? Please.
MacBook Air, OS X Yosemite (10.10.3)
