OSX Yosemite update breaks pow.cx

Question

After upgrading to OSX Yosemite my existing pow.cx install does not work. Upgrading to the latest pow.cx did not work. Also restarting it via the Activity Monitor did not do the trick.

Answer 1

Uninstalling (!) and reinstalling fixed the issue.

curl get.pow.cx/uninstall.sh | sh
curl get.pow.cx | sh

Answer 2

I had the same issue with pow.cx on my two macbooks after upgrading OSX to Yosemite.

First, One of the two Macs is fixed by updating pow

curl get.pow.cx/uninstall.sh | sh
curl get.pow.cx | sh

It fixed one of the two computers.

Then, for the second mac, pow is fixed by removing network configuration & preference file. Manually trashing the network plist files should be your first line of trouble shooting. This is one of those tricks that consistently resolves even the most stubborn wireless problems on Macs. Updating to Yosemite might have a corrupt preference file. Follow steps below:

1. Turn off Wi-Fi from Wireless menu item
2. Go to finder /Library/Preferences/SystemConfiguration/

3. Within this folder locate and select files: com.apple.airport.preferences.plist com.apple.network.identification.plist com.apple.wifi.message-tracer.plist

   NetworkInterfaces.plist

   preferences.plist

4. Move all of these files into a folder on your Desktop called ‘wifi backups’ or something similar – we’re backing these up just in case you break something but if you regularly backup your Mac you can just delete the files instead since you could restore from Time Machine if need be

5. Reboot the Mac. This forces OS X to recreate all network configuration files.
6. Turn ON WI-Fi from the wireless network menu again.
