Do you travel frequently or use a lot of public WiFi networks? I would clear out all your preferred WiFi networks except for the one you use by going to Networks>Advanced>Preferred Wifi Networks.


i would also reset my modem and router and make sure it is updated so you have a strong clean connection.


also are you using 5g network? 5g can be inconsistent if you’re having disconnect issues I would switch to 2.4ghz connection.

Hi I have already cleared all wifi networks still have same issue. Also connected to 2.4ghz connection and also connected to my iPhone via hotspot to test it does the same thing no mater what wifi I’m hooked up to. Reset modem still same issue.

i don’t believe it’s a modem issue cause it’s the wifi that completely turns on and off on the MacBook Air not just the wifi signal dropping out.
