Well I've tried all this to no avail. Rebooted router, reinstalled firmware,
restored to factory settings, makes no difference. A new router may be the
answer.

One very strange phenomenon though: when I instruct it to Connect, the
Wireless Network Connection box shows the network as Not Connected in the
heading and on the system tray icon, but in the text it says "you are
currently connected to this network". At these times I am able to connect to
the internet via wireless and the laptop's wireless NIC shows up in the
router's table of wireless clients. In Network Connections the wireless
still shows as disconnected. It seems it is connecting but Windows is not
fully recognising the connection.

After a few minutes the connection is lost. It doesn't reconnect
automatically as it should, but connecting manually does the same again.

Any advice please?
