I'm using a Sony Vaio VGN-NR280E laptop, running Windows Vista, using a D-Link router, network is not encrypted, and also running Avast! Antivirus. My laptop suddenly can't connect to my wireless network immediately. It takes about 1/2 hour before it connects. But after resuming from suspend, hibernation, or restarting the process just repeats itself.
A little back story: I was out of town for the weekend and was using the wireless at the motel that I was staying at, everything worked fine. I come home and the wireless should, after a minute, connect, instead it just keeps telling me it's not connected. After waiting for about 1/2 an hour the connection works fine and doesn't drop once I am connected. Also, "Obtain an IP address automatically and Obtain DNS server address automatically" are both selected.
Restarting - have to wait about 1/2 hr or so before I am connected
Virus check - no viruses
Spy bot check - nothing detected
Drivers - Intel Wireless Driver up-to-date
Wireless Lan switch - On and light is green
It detects the wireless network, but fails to connect. Also diagnosed the issue and came up with "try connecting to another network/troubleshoot when wireless signal is low." The troubleshooting FAQ didn't work. Why is it taking so long to connect to the network now? I'm not very computer saavy so I'm at a loss as to what to do next.
I'd be grateful for your help. Thanks.
