I have a E1705 and a Linksys wireless router with the Dell wireless card. Anyway it was working perfect this morning when I left to go to my dads. Well I took the laptop over there and he wanted to get on the internet with it. Well I had to set up a dialup connection for my laptop for him because he doesnt have cable. Well anyway it worked good over there. So later that night I came home and went to get on my wireless connection and it will not connect now. I have tried everything I know to do as usually everytime I power it up or open it Windows picks up the connection. I am not a real big computer whiz so if someone could walk me through how to fix it, it would be greatly apprieciated. I never have had the first problem with it. Even when I changed my hard drive as soon as I hit the power button I was on the web. I even deleted the dialup connection but its showing a wireless connection available just wont enable it to where I can get on. Someone please help me!!!
