Cannot connect to wifi after upgrade to Windows 10

I had always expected a few glitches after doing an in-place upgrade from Win7 to Win10 (v21H1) on my Samsung RF511 laptop (which is a few years old but in theory capable of handling Win10). After sluggish boot-up and touchpad issues (raised in separate posts), this one is about wifi connection.

The problem is simple. No wifi. Ethernet (which uses a Realtek adapter) works fine, so my internet connection as such is good. When trying to make a wireless connection, the laptop running Win 10 "sees" the wifi link. The router is a Netgear, again not the latest model. It has WPA password-key protection. But running Win10 now, the laptop "can't connect".

The laptop has a Broadcom 802.11n network adapter. With Win7 before the upgrade, the wifi connection worked fine. When dual-booted into Linux Mint on the same machine, the wifi connection still works fine. This suggests that both the Netgear router and the Broadcom adapter hardware are operating properly. The only thing that has changed is the upgrade to Win 10.

I have run the Win10 wifi troubleshooter. I've done the standard steps it asks (switch the router off and on again...). It says there is a problem.... but offers no suggestions for how to solve it.

I have looked at the network adapter properties/drivers. The driver is v.5.100.82.95 which appears to date from 2011. It is said to be working properly. Windows Updates offers no more recent version, and trying 'update driver' in Device Manager brings the message that the installed driver is the right or best one.

The Broadcom support website is hopeless, but I did find, download and install a more recent driver - v.7.5.340.0 dated 2015. No solution - the wifi still will not connect.

A laptop that can only connect via ethernet hard-wiring is not very useful. So what else can I try in order to get a wifi connection?

Windows 11 - Wifi Connection Issues

I agree with others who are experiencing wifi stability/internet connection issues since "upgrading" to Windows 11.

Sometimes it works, sometimes it doesn't. Sometimes it connects to my wifi, but not to the internet. Sometimes it takes FOREVER to connect to the wifi. Sometimes it works fine and then suddenly drops.

This is 100% related to Windows 11. These issues almost immediately after my upgrade. No other variable has changed -- same location in the house, etc. Others in the household who have remained on Windows 10 are fine. No issue with the router, etc.

This is very frustrating and has cost me a lot of time and productivity. Is Microsoft addressing this? And soon? (Based on Google searches, we are not alone in experiencing these issues in Windows 11). For me, there is not much point to logging into my computer is I can't connect to the internet. I'm hesitant to call Microsoft because I can't be confident that I will stay connected to the internet long enough to troubleshoot. :-(

Thanks for your help/attention. I hope Microsoft creates a patch/update for this soon -- and doesn't just wait for the other parts of the update they may be planning.
