I'm sorry but you don't seem to have read the bit where I said: >(no, it's not as simple as the router is not broadcasting the network name) That's the whole point, the 'broadcast SSID is ticked'. The network 'disappeared' when I changed only one setting on the router, namely selecting WPA. No matter, it is working now. I wish I could give a clear explanation of what I did to correct the problem but it involved: a) on the laptop, with wireless turned off - clearing out every reference to any network I could find - rebooting several times - then turning on the wierless asking it to find and connect to the router, unsecured - disconnecting - clearing out every ref to any network - rebooting - asking it to connect to the network, WPA secured B) on the router, performing a 'hard' reset every time I rebooted the laptop Eventually, the laptop found the network. Connecting was then trivial, I just gave it the WPA key and away it went. What ever was at fault, it was definitely something to do with the HP laptop because throughout all of this messing around an Acer laptop running Vista would connect to the network every time. stuck edited: Hmm, the forum software insists on replacing the letter b followed by a ) with a smilie
