Wireless connection constantly dropping

Hi all,

I have a 5month old macbook pro and have had wireless connection issues for months now.

My connection will drop less than 3 mins into use, requiring me to turn off wifi or renew DHCP lease or restart and zap PRAM.

I have had this problem right the way through 10.7 so I thought I would 'upgrade' to 10.8 but I have wasted my money as it hasnt gone away.

It doesnt matter what wifi network I use it has the same issues.

I have changed the channel of my router and checked all the settings to make sure there is minimum interference from other networks.

I have also changed the packet size to 'magic' 1453

The only way I can keep the connection alive is to use a constant ping in terminal.

(yes I have rebooted my router SEVERAL TIMES)

Any other suggestions?

Has any one started a petition for this yet?

Ive noticed that imac users have managed to downgrade their wireless driver to solve the issue, has any one managed this for the macbook yet?

I have to say this macbook has been the slowest most unreliable mac I have owned yet. I wish I hadnt got rid of my 21 inch white imac. That used to work twice as fast with only half the processor and half the ram!
