Macbook wifi with exclamation mark with system preferences error

Hey!, So I have been using Mac OS Monterey for a while, and I have been getting this error, So when I restart my mac, It shows the WIFI with an exclamation mark, and I tried going into Network in sys preferences, but It shows an error, also I tried going in safe mode, I also tried to use the wireless diagnostics but that too wont open, But I found a work around that is to turn the Mac off and wait 24hrs, I am a student and I need the Mac to be working all the time so that work around isn't for me....

Can you guys help me out??!!

MacBook Pro 13″, macOS 12.3

Thanks for replying but, these steps aren't working for me.... Also when I click the Wifi on the menu bar, Its just showing the wifi on and off slider which is grayed out and the option to go to Network preferences, but that leads me to another error, saying "There was an error in Network Preferences".... I don't use a VPN or anything like that.. also I as I cant open Network Preferences, I cant renew the IP address.. Also its not the issue on the side of my ISP, or the network, its working perfectly fine and connects properly on other Apple devices too....

I strongly believe this is the issue of the mac

I went to a lot of forums, and tried doing the steps but it all leads to one or another error...

But after 24hrs this reverts itself by some magic, Idk how..... But I don't have the time for it... I need the Mac to be working all the time to do my work as a student, I switched from Windows because I heard MacOS doesn't have these issues but now am screwed.... I have been experiencing this issue from a lot of time.. Also I think it isn't the issue of the network card....

PLS guys help me out

Hi there Krishnajith_A,

Check out the steps below for help getting your MacBook Pro connecting to Wi-Fi:

Restart your Mac

Restarting might help because your Mac then automatically renews the internet address it was assigned when joining the Wi-Fi network. Or you can renew the IP address manually. This is known as renewing the DHCP lease. If the lease expired and the address is already in use by another device, your Mac is assigned a new address.

Update your Mac

Update the software on your Mac, and make sure that the date and time are set correctly.

Check VPN or other security software

If you installed VPN or other software that monitors or interacts with your network connections, that software could be affecting access to the internet. Learn about network issues related to VPN and other software.

Use the built-in diagnostic tools

Wi-Fi Recommendations. Click Wi-Fi in Control Center or the menu bar and check for a menu item named Wi-Fi Recommendations. If you see it, your Mac has detected an issue and has recommendations. Choose Wi-Fi Recommendations to learn more.*

Wireless Diagnostics. Press and hold the Option key on your keyboard while clicking Wi-Fi in Control Center or the menu bar, then choose Open Wireless Diagnostics from the menu. Learn more about using Wireless Diagnostics to analyze your wireless environment.

Update the Wi-Fi router

If you manage the network's Wi-Fi router, install the latest firmware updates for the router, as recommended by its manufacturer. It might also help to simply restart the router and use Apple's recommended settings for Wi-Fi routers and access points.

Try a different network or contact your ISP

If you can access the internet when connected to a different network, or you're not sure, check with your network administrator or Internet Service Provider (ISP) to make sure that your network is working properly.

These steps can be found in If your Mac isn't connecting to the internet over Wi-Fi.

We hope this helps.
