I have a D-Link router and Comcast cable internet. I have one computer hardwired to the cable modem. I have a wireless network set up in the house. Until recently both my laptop and my daughter's connected automatically to the wireless network. Very recently my computer had a nasty lose-everything crash and Windows, etc. was reloaded. Since that time, my laptop will not connect to my home network. It will connect to other networks everywhere else, but not mine. The problem seems to be assigning an IP address. THat seems to be where I keep getting stuck. When I go into my secured network properties, and put in my network key/password, I can see that I get connected for like a nanosecond, then it shows me not connected.
I've tried resetting the modem and the router. I believe I may have had to assign a static IP address in the past when this happened last year, but I'm not sure where to find an IP address - DNS number, etc. And would that preclude me from hooking up to other wireless networks automatically?
The computer repair company I took the laptop to when it died told me that it would have to be a $90+ housecall for them to see what was wrong with it. I'd prefer to figure it out on my own (with your help, of course!).
