My wireless connection (airport) keeps dropping the connection to my wireless router, but only when I got to battery power. I have to wait until it finds my network again and then click on it and it works for about 5 mins or so. I am running a newer (bought in April) MacBook Pro with all the latest updates. I know this problem occurs only when I go to battery, as soon as I plug in the power cable, the connection is solid. Any idea as to why this is happening? Thanks.
