How to solve problems with your Wi-Fi network

You should also be aware that DECT cordless phones and microwave ovens can emit signals at the same frequency used by Wi-Fi, so if you find your connection drops, check these devices are not in use when it happens.

We've recently come across a problem with Vista and some routers where the wireless connects for a short while, then disconnects, sometimes causing the router to reboot. The problem is with Vista's implementation of something called IPV6, which is not supported by older routers, and seems incompatible with some newer ones. If you are having problems, click Start > Control Panel > Network and Sharing Center > Manage Network Connections. Right-click on your wireless link, choose properties, and untick the option to use IPV6.

Step 1: Basic facts
It's worth having a copy of the Router's IP address handy, just in case you can't log on. Click Start > All Programs > Accessories > Command Prompt. Type Ipconfig and make a note of the number. If you can't connect to your router wirelessly, connect an Ethernet cable instead.
