I have just bought a Belkin N1 Vision Wireless Router, the one with the LED message board, anyway it is easy to set up and has WPA-2 security which is a definite improvement on my old router, which wasnt even G level, although it did serve our 2 Desktops and laptop. However the problem is with my Acer Aspire 5610 Laptop, it just won't allow access to my new wireless network. The 2 desktops are fine and were set up on the new security level. There is a red cross against the network when looking on the Laptop. Can anyone advise how I can resolve this.
