Linksys Wireless Adapters :: AE3000 USB Adapter – False Network Detection?

I recently purchased a Linksys AE3000 Dual-Band Wireless-N USB Adapter as an upgrade to my Dell Desktop Computer and to compliment the Linksys EA4500 Router that I recently installed. Generally it seems to work well and the 2.4 GHz network status typically shows speed to be 450 Mbps. However, I’ve discovered if the computer goes to sleep based on my power plan, when it comes out of sleep the “Available Networks” will show the network I’m connected to (2.4 GHz network) and a false network identified as “Other Network” with a Red “X” where signal strength would normally be. When I mouse over it; it shows Network Name: Other Network; Signal Strength: Excellent; Security Type: Unsecured; Radio Type: Unknown; and SSID: Other Network.
 
Initially I thought this was an anomaly caused by having both bands of the Router (2.4 and 5.0 GHz) set to the same SSID, so I changed the 5.0 GHz band to a different SSID and set my Media Players to access the new SSID. However, now when the computer comes out of sleep mode, Available Networks will initially only show the Router’s 2.4 GHz SSID and the phantom “Other Network”. It takes a while before the Router’s 5.0 GHz SSID shows up. We live in the country, so there are no other networks close to us, just my home network. It never shows the “Other Network” when I start or restart the computer and if I disable the adapter and then enable it, the phantom network goes away until the computer goes into and out of sleep mode again. Also, I uninstalled and then reinstalled the Driver and then reinstalled the Adapter using the Cisco Connect Software and the problem still exists. Finally, I disabled the Router’s 5.0 GHz network and the phantom network no longer appears under any conditions. The Dell (Atheros Communications) Wireless Card in the computer doesn’t have this issue under any scenario. On both the AE3000 and Atheros Adapters the 2.4 GHz network shows a signal strength of Excellent (5 out of 5 bars) and the 5 GHz network shows Good (3 out of 5 bars).
 
How to correct this issue? With the issues I’m having with the EA4500 and the AE3000; they are both probably going back to Amazon.
