Windows 10: Upgraded to Windows 11 and now cannot connect to corporate WiFi

Recently upgraded to Windows 11 and now cannot connect to our corporate WiFi network. I tried all the troubleshooting suggestions from the Microsoft Community Forums and other websites, but had no luck resolving the issue. I can connect to our Guest Network and others, but not the Corporate WiFi.I am not sure if it is related to the server-side Certificate issue expiration, and whether it needs to be renewed. I would really appreciate any insight and help on this.Thank you.

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?

 

When will the wifi connectivity problems be solved?


OK, so the Windows 10 engineers bollixed up the wifi connectivity part of the operating system. Everybody knows that by now. It seems they are making some progress in resolving it. Now, instead of seeing "Secured, No Internet" on your list of wifi connections, you see "Connected, Secured" EXCEPT no webpages will load. So you really aren't connected. It does seem to be a step in the right direction. Does anybody know when they plan on a full and complete repair of this screw up of epic proportions?

 

Can't connect to wifi after Windows Update

I have now tried all of the suggested steps at least twice.

The only instance of seemingly achieving any progress was the first time I performed a clean boot, when the wifi connection actually worked. But after that, I tried following the steps to isolate the problem and then after restarting the computer, all of
my wireless features have disappeared again. I have tried repeating the entire sequence of steps again, but the wifi hasn't worked again. It just worked that one time, but I don't know why it was different that time.

I have been trying to fix this for over 11 hours, but haven't been able to connect back to wifi.

I would like to know if rolling back the Windows Update is an option and, if so, how to do that and how to prevent Windows from updating again.
