Cant turn on wifi using yosemite public beta

[connor2198]

I have tried everything I can think of including restarting, turning on from preferences, turning on from diagnostics and from the status bar. Nothing has worked so far.

I have resorted to ethernet cable and want to know if there are any solutions or if anyone else had this problem with Yosemite public beta.

Same problem, solved repairing permissions and disk on recovery mode ( cmd + R) and connecting to wifi on recovery

Hmmm, have had no problems here with wifi since the beta came out.

What's the specs on your system? No problems with wifi here on an early 2011 MBP either.

same here. except 2.4g works fine and 5ghz N flakes out on my airport extreme. seems like a interference, range issue even though opt/click on the wireless icon in the toolbar appears ok. watching stat menu it looks like the upload sends data for a site/share etc, but nothing comes back then eventually wireless dies
i say this because if i go closer to the AP, after a few minutes N starts working again and i can go back to the other room.
none of these issues occurred while on Mavericks.
