Q: Mac forgets home wifi network every time

@Movitar

I concur, it worked for me for a couple of times and then it stopped working. The issue started happening again.

I changed my router wireless security encryption setting and issue was solved, been a week and no connection drop, even after wake from sleep my iMac mid 2011 was able to instantly connect to WIFI.  The encryption setting on my router are Automatic(Recommended), TKIP, AES.  By default it sit on Automatic(Recommended), I changed to TKIP, rebooted the router and have never seen a drop for the past week.  Hope this helps some of you out there~  Cheers~

THANK YOU, JAHelms!! This was truly a nuisance. Nothing worked, until this. Thanks, again.

This was an ongoing problem for the past few months. Your solution took me a total of 45 seconds. Thank you!

Thank you, I think this has now sorted the problem out, its been going on for ages……..

JAHelms' fix didn't work for me either, but the following seems to have done the trick:

Network Preferences --- Advanced --- Click on the + --- Click 'Choose a Network' --- let it scan, and click on the network you want --- 'OK'/'Apply' everything.

It seemed to reset what my Mac was searching for all along.

So I was looking for an answer to this and kind of figured out a solution. I am using a work supplied computer that has been corpified, but we have multiple guest networks that I use for testing software since the corp network treats everything as hostile and does not allow me to do my job.

Select System Preferences > Network > Advanced

Select the WiFi tab (if not already selected)

Click and drag the network you want to use as default to the top of the list and [OK] out of everything.

I performed a couple of reboots and put the system asleep multiple times and I am still connecting to my preferred network.

Worked for me, too. Bless you!
