Are you picking up a valid IP address that the router is handing out?
Have you checked your cabling to make sure it's not damaged and has a good connection?
yes. It doesn't even show a connection was lost. It just refuses to allow me to access the internet. It will work for a while, then poof. "Unable to connect to server." The only way to re-establish is to unplug the router and restart the Acer. No problem with my HP laptop, the connection is still available and I can access web pages.
After I reconnect, I disable "use windows to configure my wireless network settings" and the connection lasts much longer. In fact it hasn't dropped once today. I wonder if that was the fix? It seems odd though.
