The Wi-Fi can be working perfectly on our other computers, on our phones and on the kids’ Xbox, but within 5 minutes after turning on my laptop the Wi-Fi stops working on everything in the house. We’ve had Xfinity Internet for years and the Wi-Fi has always worked perfectly until recently.Ī couple of weeks ago my Dell laptop started causing our Wi-Fi network to completely shut down every time I turn it on. I have a really strange problem that I need help with.
