On turning on my Macbook Air I have a strong wireless connection to the ActionTec router and a connection to the internet. After about five minutes the internet connection drops but the wireless signal is still strong.
The internet access from an iMac with an ethernet connection works fine all the time.
The Air works flawlessly with the wireless at ny office and in other locations.
Rebooting computer and router hasn't correceted the problem.
Any suggestions?
