Is there a real fix for this issue, or should I just reinstall my last version ?
MacBook Pro 13″, macOS 11.2
Not knowing what you have tried to remedy this yourself (other than booting up in Safe Mode,) please take a look at the following article to see if it can help:
In general:
"works in safe mode"
"not in regular mode"
means, it's something you added.
In my opinion, unless you MUST have a VPN or proxy for work purposes, they mostly get in the way and are WILDLY over-rated for protection against anything. Your local wireless link is already encrypted, and your Macs are protected from direct attack by the Network Address Translation firewall in your Router.
Typically, when your notebook can connect to the wireless router, but not to the Internet, there may be an issue with the DNS settings used by the notebook.
Go to System Preferences > Network > Wi-Fi, and note the DNS servers listed. Are these the ones you expected? If your ISP is providing your DNS services, then they should be their's listed here.
Now give the following a try:
Please post back your results.
p.s. A few more questions if you don't mind:
Hi, and thank you fo this.
I tried all sorts of guides, and got to that one late in the process.
Since safe-boot connected fine,
and that macbook connected fine before the upgrade,
and every other device at home connected fine as well,
and the macbook failed to connect to other networks, say, my phone hotspot, and my wirk wifi,
I figured that most of the steps in that guide are redundant, as they refer to the router/ssid/security/distance/diagnostics etc.
So I read through it and found tha I already tried all.
The wifi diagnostics just said - "you are conbected to wifi but not internet", which gets me nowhere, actually.
Thanks again

Hey -- Thanks again <3
It is not a DNS thing; I can't event ping the router - though the wifi connects fast and easy. No ping was successful, not even 8.8.8.8/8.8.4.4. 100% packet loss every time
I use a VPN, but can't set it up (for the same root cause), so checking with/without it is not yet defined.
I checked the proxy settings - all checkboxes are off.
The fact that you can ping the router only means that the connection between the Mac and the router appears to be ok. Since you are not able to get out of the router to the Internet indicates that your router is suspect.
Have you tried simply restarting your router to see if this resolves this issue? If so, and it did not, what is the make & model of this router? Is it only a router or a combination router/modem (aka, gateway) device?
I can't ping the router.
Restarting the router nade no difference.
It's a TPlink 9970 (and a vdsl connection).
But, focusing on the router would make sense if i could get to the internet on any other wifi. I can't.
To either, it connectd fine, get an IP (i.e. dhcp completes ok), but can't ping the router nor the internet.
Sorry, about that. You did say you couldn't ping the router. My mistake.
Just to be sure, can your MBP access the router/Internet, if connected by Ethernet?
Going back to Wi-Fi, have you tried creating a new user account? Then log out of your current account, and log back in with the new one? If you can access the router/Internet with the new account, then we narrowed down the issue to your current account.
I was working from home, without a docking station, so could not check the (wired) ethernet connection. Bu my guess is it would have worked.
I am currently using an alternative (catalina) macbook, so cannot reproduce the issue.
Also, it is a work computer, as you pointed out, so vpn is a must.
Thanks again (and again and again)

Ok, it would have helped if you let us know that this was a company-provided notebook.
Since it fails to connect to any Wi-Fi network, and your company's IT folks have already tried to resolve this, the only other thing I can add is that they provide you with another one that they verified can connect to Wi-Fi networks before expecting to work from home.
We could spend more time troubleshooting the notebook, but again, since it's company-owned, the onus to do so should fall on them. Good luck!
Oh,and yes. The IT engineer tried to reinstall Big Sur, as well as a new user account, to no avail, unfortunately.
indeed a VPN upgrade solves this. Sorry for dragging you through the unknowns.
I figured I'd share this so everyone with an issue will find some sort of resolution.
THANK YOU
BigSur wifi issue - connected but no internet. Have internet in safe boot.
