Dell N5040 Laptop Windows 7 Home Premium (64-bit) SP-1 Dell Wireless 1502 802.11b/g/n Network Adapter  Western Digital WNR2000 Router   Up until recently, I’ve had no problems with my Dell Laptop connecting to our home network. In the last few weeks however, I have not been able to connect.   My laptop sees the network but will not connect automatically or manually.   Other wireless devices in the house see the network and connect normally.   I have taken the laptop to a neighbor’s house and connected to their network without difficulty.   I have tried a few troubleshooting items myself including:   Incidental info:  I have recently replaced my old Dell XP desktop with a new Dell 8.1 desktop.  I have the internet line connected to my modem, then to the router, and finally to the new Dell desktop (I'm including this info as the laptop problem may have started about the same time that I replaced my desktop-not sure though).  It’s puzzling because the laptop seems to function normally at other locations, my router is obviously working as other wireless devices are not affected, however when the laptop is in our house it will not connect even though it sees our network.  Thanks for any suggestions you can provide.
