In 2021 I was using laptop Lenovo P53 with my home wi-fi network and public networks as usual without any problems. After that I needed to relocate for some time (since then I've got several windows updates and drivers updates). When I got back I noticed that my laptop could't connect to my home wi-fi network anymore. When I was trying to connect, it was just showing me "Connecting" and in the end "Unable to connect to this network". Moreover I noticed that the laptop was not able to connect to some wi-fi routers in hostels that I went to.
However there is no problem with connection to my iPhone Wi-Fi hotspot, or to Wi-Fi at my workplace. From the other side, my iPhone and my other old laptop can connect to the home router.
I've been searching for possible solutions on forums but with no results. My laptop is still not able to connect to the home Wi-Fi router.
Actions that I've performed:
- Full reinstallation of Windows. Current version - Windows 10 Pro 21H2.
- Installation of the latest (date 16.01.2022) version of Wi-Fi Intel drivers - version 188.8.131.52 from the Intel website. As can be seen on screenshots this driver is fresher than that on the Lenovo Website. Also I've tried to install some old drivers to check but with no results.
- Changing and experimenting with adapter properties. Literally I've changed and tested every parameter in adapter "Advanced" tab including wireless modes, band width etc according to some forum recomendations. Still no results.
- Additionally I tried to change some router parameters, but it did't help. So I kept them the same as they were before (on the screenshot) when everything worked and my laptop was able to connect to the router.
Please help me to find a solution.
P.S. Router settings haven't been changed at all for 2 years. The only things that have changed are - Windows version and Wi-Fi driver version.
P.P.S. I suspect that the problem can be connected with old routers with wi-fi standards 802.11b/g/n. Because at work I have a new router and everything works fine.
