Wifi Issues with OS X Mountain Lion - temporary fix

Today I've been experiencing a critical Mountain Lion OS X issue on my MacBook Pro. Googling it gave indicated a short term fix is to use the ping command in the terminal, and ping to your router, and that will stop the Wifi going to sleep, and won't impact the internet speed.

This problem is affecting OS X 10.8.3 and 10.8.4 :-(

1. Open Airport Utility to find out the IP address of your router (assuming using an Airport Extreme or Time Capsule)
2. Open terminal window
3. Type "ping 10.0.1.1" where 10.0.1.1 is the ip address of your router
4. Leave this running and it will keep the wifi awake.

I hope Apple fix this soon.

Loss of page rank gone down to zero

Unfortunately my page rank of www.kevingordon.org.uk has gone down to zero (0), when it used to be 3 or 4, that might explain why the traffic to the site has also reduced.

It isn't clear why the page rank has gone down, but it may be related to the Twitter and Blogger plugins I've put on my home page. So I've taken the following actions;

1. Removed the Blogger and Twitter plugins from my homepage
2. Added a description meta tag to my home page
3. Now hoping for the best :-(

I will review in a few weeks and see if it's made any difference to my page rank, but going down from a page rank of 3 or 4 to zero seems some what unfair.

Please let me know if you have any other ideas why the page rank would have gone down so much?
