Changed to Sonoma 14.5 on Mac Mini 2, lost wifi

Where is it getting its Wifi from?

If a Phone or iPad is involoved...

You can try it manually in a terminal window: sudo ifconfig awdl0 down

To reverse the command, type: sudo ifconfig awdl0 up

sudo will ask you for an Admin password that won't be echoed.

Carefully type your admin password when asked & hit enter.

The command disables a virtual network interface that's used for ad-hoc WiFi by features like Airdrop; I personally won't miss them. So far, I've gone from losing my connection 20 times an hour to being stable for 3+ hours.

Have you tried restarting the mini?

I had a similar problem with my iMac last week and after fiddling around for a couple of days I restarted and the wi-fi was back to normal speeds.

Two things usually work for me . . . restarting the Mac or restarting the router.

In the case I mentioned, my iMac wi-fi was pathetically slow or stopped whilst my M2 mini was fine so the problem obviously lay with the iMac.

Every now and again for the past 19 years my broadband has dropped to a crawl and the telecoms company has insisted on testing my equipment which has always been faultless because the problem always lay in the 60 year old copper cables of their system! Once it took them the whole of summer to rectify the problem and I had engineers visiting every couple of weeks or so to check my equipment even though there was nothing wrong with it. They would tweak something at their end and the broadband would be full speed (36 mbps) but would drop every day until after a couple of weeks it was down to under 1 mbps!

Let us know how it's going please.:)

was there anything particular that you fiddled with? I have had a very slow network which keeps dropping out and I do not know what to do about it.
