Laptop can't discover/connect to wireless networks.
I have been having this problem for 2 days now. My computer was working fine, and I went to go do something, so I shut my laptops lid to put it to sleep. I came back about 5-10 minutes later, and it had a red cross on the network button, at the bottom right of my desktop. I tried turning the Wi-Fi on/off with F2 + Fn, but that didn't work. I have checked in device manager, and everything seems to be working. My wifi card is an Intel(R) WiFi Link 5300 AGN.
Currently running this on a Dell Studio 1557, with Windows 7 Home Premium 64bit. I've had this laptop for almost 3 years now, and it has never been a an issue. I've tried restoring my laptop to a couple of days ago, but that has given me no results. I tried running the computer in safe mode with networking enabled. I enabled my wifi with the fn + f2, and I saw my wifi network. However, while it was connecting, the connection was lost again, and I'm yet to see it. After disabling and then enabling the driver, it would show the network for about 20 seconds, then it would be missing. Now, I can't even see it at all. All my other computers/devices can see my network, and it can still connect with it's Ethernet port. This problem is really starting to be a pain, since my laptop is pretty useless if it can't have portable internet. :P
