Check the Time Zone for your Wireless Router

When I set up a new wireless router, it wouldn't allow connection to the Internet.

The radio signal was loud and clear. When I conected the boudband modem directly to a computer, Megaherz of conectivity came gushing through, but through the router there was only a local connection.

Eventually a sharp eyed friend looking through the settings, spotted something I'd missed. The router, which was made in China, had its clock set by default to Hong Kong time.

Once he changed it to British time, all was well.
