I have netgear wireless router and run a macbook and Reciva internet radio off it for some time without major problems. At Christmas my wife bought a toshiba laptop which connected without difficulty until Saturday when everything went pear shaped. The mac continues to connect fine but the other two seem to have dropped off.

The message coming from the internet radio is dns servers invalid.

On the laptop there is still connection to the router but no internet access. When I the router's iP (from that computer) it couldn't find any internet connection.

The only things that changed on Saturday were

a) I installed Creative Zen software
b) I disconnected the router from the cable box (and then recoonnected) when trying to move the boxes

I have rebooted both the broadband box and the router many times to no avail

Help!

Many thanks
