iMac Wifi issues

Hi. I'm having difficulty connecting to wifi on my iMac. No issues with my macbook pro or iphone. The wireless diagnostics keep asking me to check stuff relating to the router but if that's the issue, then all my other devices shouldn't be working

iMac 21.5″ 4K, macOS 10.14

A Few Thoughts:

I. Reset your SMC and your NVRAM:

Sometimes changes (i.e. Installations) are made to the system and then settings (i.e. Networking) become corrupted, technically. So, reset both on your Mac. So, reset the SMC and reset the NVRAM or PRAM. It might take three tries. to fix this. So, be certain you have the time to do so.

Make a New Location, Using network locations in Mac OS X ...


System Preferences>Network, top of window>Locations>Edit Locations, little plus icon, give it a name.


System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.


The interface that connects to the Internet should be dragged to the top of the list.


Sys Prefs>Network>highlight the Interface you're using>Advanced>TCP/IP>Configure IPv4: Using DHCP.


If using Wifi, instead of joining your Network from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed.


System Preferences>Network>choose interface>Advanced>Proxies Tab, make sure none are set, like for HTTP & HTTPS.


System Preferences>Network, unlock the lock if need be, highlight the Interface you use to connect to Internet, click on the advanced button, click on the DNS tab, click on the little plus icon, then add these numbers...
