Mac Pro WiFi keeps disconnecting

Over the last couple of weeks both my Mac Pro (OSX El Capitan & High Sierra) keep bumping off the wifi connection.

It happens multiple times an hour.

I have researched it there is multiple solutions none seem to work permanently yet.

Even more strange is the Mac Air are not experiencing this problem??

Anyone have any suggestions?

Re: Mac Pro WiFi keeps disconnecting

@itsbardi  Tell us some more about your configuration.  You may have gone through some of these points.


What is the Modem you are using, firmware level.

Have you factory reset the modem with paperclip.

Anything else changed in your network two weeks ago.

Are Mac Airs using Apple  Catalina or are they closer to the modem.

Mac Pros would drive faster on LAN cable - is there a reason why you use Wi-Fi.

Do you see two SSIDs for your modem (is Band Steering or Beamforming Enabled if in modem)

Are you using 2.4Ghz or 5 Ghz 802.11a or 802.11ac for connecting the Mac Pros.

Have you used the Airport Utility Wi-Fi Scan function to see what Wi-Fi Channels are being used by your modem and any adjacent modems in your area - if adjacent modems use same channels, yours could be bumped off.

If you are using 5 Ghz ac - what Channel/s do you see being used. Check if modem Wi-Fi setting for Wi-Fi Channel Aggregation Auto 20/40/80 Mhz setting - that will generally limit the number of channels 5Ghz 802.11 ac will connect to.

Drop power output on Wi-Fi radios from 100% to 90% to see if more stable.
