I have recently bought a new laptop (Dell Vostro 1200). The wireless card installed is Intel(R) wireless WiFi Link 4965AGN and it came with Intel(R) Proset Wireless Manager. However, I uninstalled the software.

My laptop was working great wirelessly(in the office,at any wireless hotspots), until I went back to my own house. Each time I tried to connect to my home network, I got limited or no connectivity message. However, my laptop can connect to the internet using LAN cable.

I suspect its configuration problem.However, before this I can use wireless with my old laptop with exactly the same TCP/IP configuration. all the other laptops in the house are connected without any hassle.

thanks for any help.
