I am connected from the office in the back of my house via my ASUS K55A laptop with the built-in Qualcom Atheros single-band network adapter. I have about 100 yards to reach my Cisco Linksys E2500 dual-band router inside the house. It usually works but is somewhat intermittent. We tried to improve the signal by buying an AE2500 Cisco dual-band adapter shown here http://screencast.com/t/FIDbIgI4Jt3W
. It installed properly with the disk supplied but I can no longer see the 5ghz network when I plug it in despite the fact that the 2.4ghz is working. How can I get the 5ghz network to show up when I plug in the Cisco AE2500?
