I have a Toshiba laptop running Vista, with built in wireless accessed through a Netgear 54Mbps router connected to a Virgin Media cable modem. The laptop sometimes loses connection, more often recently, and also occasionally fails to connect on startup. When this happens I am forced to turn all the network devices off, unplug them and reboot them all, followed by the same procedure on the laptop. I also have a second Toshiba laptop with similar spec running XP, which never encounters these problems. Has anybody experienced this and can they offer any advice?
