No internet connection after installing yosemite

After installing Yosemite, I have no internet connection. If I hold option key, my wifi description shows Internet as unreachable,although all my bars are dark and the rest of the settings look the same. When I connected via cable, it did not show an Ethernet connection. My pc and iPad work fine,so it isn't my carrier. Anyone else have this problem and know a fix??? Thanks so much for any assistance..

iMac, Mac OS X (10.6.8)

I am having this exact same problem!


I have not tried Chrome yet, but I have Parallels installed with Windows 7 on it, and through that I can connect to the internet. So, the VM I have running works, but Yosemite itself does not, at least none of the Yosemite apps I have tried, such as mail, safari, app store. I don't think Firefox works, either.

I went into the Apple Store and they deleted all of my internet info in the system settings, so it would all be new. I got home , found my wifi connection listed and put in my password and it still would not work. Oddly, I can log into my neighbors wifi with no problems, and there are no problems with anything else in my house connecting to the wifi. Going to call them and see what other suggestions they have. If they work I'll post ASAP.

You are on to something here.


I tried unloading, and it was not found. I then loaded the file, and magically all my apple apps made their network connections and started working.


But here's where it gets funny.


I logged off, and into another use account and I had no network connection.


I logged back into my account, and had no network connection. I needed to unload and load the file again for the network to return.


More troubleshooting ahead...
