My M1 MBP stopped connecting to WiFi — What can I do????

[kat.hayes]

All of a sudden, my M1 2021 MacBook Pro (16-inch, 2021) 64GB of RAM is not getting onto my home network easily. I am typing this right now from my bedroom on my 12.9 inch iPad Pro 5th gen while my the MBP in the same location will not connect. I am also streaming live TV right now in my bedroom from my AppleTV, however, my MBP will not connect. It was never an issue until some time last week….

I have an Orbi router with two different network frequencies, and when I select either of them it searches and never connects. I have been able to walk to different locations in my house and it was able to connect, and then when I walked back into my bedroom it seemed to keep the connection, though I only tried that maybe once and it could be unrelated. There are also other times that I have been able to connect to WiFi on the MBP from my bedroom. It all seems very random as to when it will connect and not connect, and I can not make any sense of it. However, the AppleTV has consistently connected from my bedroom while the MBP will not. I have also rebooted the MBP.

I unplugged my modem and router yesterday and that did not seem to change anything. I need to find a way to resolve this ASAP because I need reliable internet for Zoom meetings ASAP.

1. Why would the the iPad and AppleTV be able to connect to WiFi in the exact same spot that the MBP can not?
2. Is there some setting I can try adjusting on the MBP to make it connect more reliably?
3. Is there some setting on my router I need to look into?
4. Any other suggestions?

Thanks!

There is a similar discussion on a Mac troubleshooting website I follow:

MacBook Air M1 will no longer connect to wifi and the world

My friend has a MacBook Air M1 - it has been working as it should until a few days ago where it will now not connect to the internet. The wifi symbol shows in the task bar, the Mac shows it’s connected in settings, I’ve tried a connection via ethernet, that too shows a connection plus hot...

Unfortunately, there doesn't seem to be a common cause shared by posters to that thread.

I just checked the settings based on the post you referred me to and under WiFi it states “Self-Assigned IP” and it also states “Wi-Fi has the self-assigned IP address xxxxxxxxxxx and will not be able to connect to the internet”

What does this mean and is there something I can do about this?

Thanks!

Settings should be DHCP.

Settings should be DHCP.

1. Is there a reason it would have been setup this way? I have not changed anything recently, so this must have been setup this way since I got it.

2. Where do I change it to DHCP?

Thanks

Settings > Network … click details

Can you try other locations (routers) with WiFi? Does it work there?

“Self-Assigned IP” and it also states “Wi-Fi has the self-assigned IP address xxxxxxxxxxx and will not be able to connect to the internet”

What does this mean

I’m not a wireless or networking expert but if I recall correctly, those messages are the result of not having a connection to the Internet somewhere in your setup.

One thing I have to do occasionally on my own Wi-Fi network is shut down my Mac then restart my Wi-Fi router. Then, after the router’s status lights show it is fully connected and broadcasting its Wi-Fi signal, I boot my Mac. The symptoms of the underlying problem, which I’ve never taken the time to track down fully, are the Mac cannot connect to any websites, mail servers, or other services outside of my internal network.

When I've had weird wifi connectivity problems, one problem that comes up is my VPN is somehow trying to connect when I don't want it to or connect without my knowledge, and then that messes things up. One time Cloudflare WARP 1.1.1.1 app was enabled (and I don't know how that happened) and that stopped all internet connections for me. Once I discovered it and deleted it, all wifi returned to normal.

So if you have a VPN, a proxy or some secure internet thing on your Mac, see if that is responsible for your wifi connection issues

Here's something to try.
It won't hurt anything.

(what follows is for OS Sonoma - may work in later/earlier versions)
Open the network settings.
Your non-working wifi should show up at the top.

Click the "details" button.
At the bottom of the window, click "forget this network".

Close system settings and REBOOT the Mac.

Open system settings --> network again.

Your home network should NOT be "at the top", since we asked the Mac to forget about it.
BUT... it should show up in "the list below", close to the top.

Place the pointer over this listing, and then click "connect".
(you can only see the connect button when the pointer hovers over the network)

Does it connect now?

I would also go to "details" again, and UNCHECK
- low data mode
and
- limit IP address tracking.
