I have a PC with a cable modem and a Linksys wireless router (BEFW11S4) and a Linksys USB network adapter (WUSB54G v.4). I have had no trouble for 3 years and suddenly I was having to use Network Connections and Repair Connection to connect. I went to the Linksys website and downloaded EasyLind Advisor and ran it. I also uninstalled and reinstalled the network adapter using the original installation CD. EasyLink shows that the wireless connection is fine; however, when I try to connect the signal strength is excellent but the status message is "acquiring network address." I am hoping that there is an easy answer to reconnecting the wireless network so that my husband can connect with his business laptop again.
