My newish laptop has recently developed a fault. Every 5 mins or so it drops the wi-fi connection. I beleive that's what's happening as all web pages time out and I can not even log in to the router. The wifi icon shows connected throughout though. No messages are left in the Event Viewer log. All drivers on the laptop are up to date as is the firmware on the router. My other laptop works all OK. Any pointers much appreciated. Thanks.
