Ok, so I have 3 laptops all connecting to my wireless home network. It is a linksys wireless router/dsl modem. With a Sony, HP and Dell laptop.
The Sony and HP work perfectly but the Dell which sits 2m/6ft from the modem keeps losing the network connection. Then I need to restart the Dell before it will connect again. The other two laptops which sit about 18m/60ft away in another room never lose there connection.
