I have downloaded Win 10 to my Win 7 Dell Laptop using a WIFI connection without difficulty, even though the router is upstairs and the lap top was downstairs. Now I find that I cannot get on line even with the laptop next to the router. A series of messages from MS trying to connect me with a series of check routines, none of which help. However using a Ethernet cable connection and I have immediate full internet access. A puzzle as to why I could download and install Win 10 using a WIFI connection but now am unable to access Win 10 except by Ethernet
Possible that the Win 10 upgrade has deleted/removed your wi-fi cards drivers, or..Win 10 does not support the wi-fi card fitted to your laptop. This is usually the problem, if it was working before on Win 7, and not on Win 10 (you might find other drivers need updating as well, these may well show up when you open the device manager, as they will also have the yellow triangle next to them. Think I had to reinstall the touch pad drivers as well??) Not sure what model you have, but this may help at least.
You can check by opening the control panel, and then the 'system' icon. then use the 'device manager' icon to open the device manager. If there is a problem with the wi-fi card, you should have a yellow triangle by the 'network adapters' icon.
If so, you may well need to download and install the correct driver for the card. This happened to me , with a Dell laptop as well a while ago, and that's how I sorted it.
Thanks to you Hugh. This is past the limit of my knowledge and experience. In 18 years I have never had to update a driver. I can go with your instructions about opening Control Panel and Device Manager and see what I can find. I am rather busy still using Win 7 Desktop for all of my Docs Pics and email at present but will report back asap
Hi Cybmole and J Brennand, apologies for the long delay, but better late than never. As you both suggested I bought a Wifi adaptor from Amazon but no luck, still no internet Wifi connection. As before Ethernet connection perfect. My only thought is that my Router is a Virgin Media supplied one marked as Netgear and was supplied many years ago as a newer version of the original one. Speaking in a state of ignorance, could this be a possible source of my troubles?
