MacBook Air (Retina 2018) keeps disconnecting from home WiFi network

[xerenthar]

I don't understand what could be happening. I have an eero system, and nothing else is having this issue, including other Apple devices (Apple TV, multiple iPhones). My MacBook Air keeps connecting for a split second and dropping connection. I don't know why and no errors are shown. I have reset NVRAM/PRAM and turned off Bluetooth, as well as restarted my computer, my eeros, and my modem. The only thing that does work is deleting the files: com.apple.airport.preferences.plist, com.apple.wifi.message-tracer.plist, NetworkInterfaces.plist, and preferences.plist, and then restarting. The first time, this worked for two weeks. Now it's every three days or so. Because the deletion works, it makes me think it's a MacBook issue -- but what could it be, and is there a way to permanently fix it?

Could be a DHCP issue. Try setting a static IP.

do you mean a static IP for the macbook internally (i.e. a 192.168.x.x)?

You can set it in your router.

Can you use a newer router?

Any insights from errors reported to the console?
