I just bought a Dell inspiron 5030. Apparently it came with an Atheros AR 9285 802.11 b/g/n wireless card. I cannot get this thing to connect to my home network unless I am sitting right next to the router! I have about 8 different wireless machines on this router working perfectly all over the house including one in a shed about 50 yards away! I have a range extender. This laptop can recognize the network at very close range only. I have a dell inspiron last year model with a Dell LAN wireless card that works great. For example when I am in an upstairs room, the 1 year old laptop is picking up about 6 different networks, whereas this new one I just bought is telling me no networks are available! I have tried looking for newer drivers, changing the power settings for the adaptor, restarting the router. The router is a lynksys WRT54G2 v1.5. Unfortunately there is no indication that the wireless adaptor is not working. It just isn't. What's the deal with this card? Any suggestions?
