Q: Wifi ISP fails
I have a problem with my 2012 MacBook Air running 10.10 Yosemite. It will connect to the wifi router fine - even shows me other computers on the home network so I have a network connection however the ISP, Internet , Server all show failed (red) in the diagnostics. My router is a Linksys WRVS4400N enterprise router firmware 1.1.13.
Before upgrading to Yosemite I never had this problem when I was running Mavericks. I left the country for several months and upgraded to Yosemite while I was away. When I returned I could never connect to the internet using wifi - using ethernet is not a problem - it works fine.
So I sold my first Macbook Air and bought another 2012 model and it has the exact same problem - new clean install of Yosemite. I have searched far and wide and yet to find an explanation or a fix. There is a litany of proposed solutions none of which have worked.
I will note that the first MacBook Air connected to another network without a problem - the new one I have yet to check outside my own network.
When running the diagnostics in the Network Settings the ISP and Internet indicator lights might flash to green momentarily as if it resolves its problem but then reverts back to red (failed) very quickly.
MacBook Air, OS X Yosemite (10.10.1)
