I have two wifi ISPs, StarLink and iLox fibre. I desire OSX to fail over between the two ISPs, defaulting to the fastest internet speed.
Apple would have to add more advanced network failover code to the operating system, or you need an edge device (e.g. router) that can do that for you upstream of your Mac.
If there is no Internet, it will try the next service down in the service list that is connected. If you can establish two Wi-Fi services connected to different signals through one receiver, you have on your Mac, if that one drops the Internet, it would fill down to the next one in the list, however, if they can still reach the Internet, it won’t drop the service. How fast the Internet is on that connection has nothing to do with it.
my guess is that will not work with the single Wi-Fi receiver in your Mac. I don’t know if it would work with an external Wi-Fi dongle.
Is speed your determining factor or just internet? I don’t believe speed is in any way used.
For just internet as determining factor, can you add a second Wi-Fi service to the same location? I’m not at a Mac to try. My guess is both services would connect to same service as you only have one receiver.
There are two wifi signals from two different ISPs. As one service loses internet (speed goes to zero or veryslow) i want the computer to use the other ISP.
SO the question becomes does the Mac have wifi multiHoming capacity?
Apple tech support will have to answer about the failover. There is the Wi-Fi assist in cellular settings.
I do know one can use a access point/router and make connections to it “without” internet access. Network connection will show a yellow exclamation mark on Apple Wi-Fi , indicating what I believe is no connection to a DNS server on internet.
However the Wi-Fi access point will work, ie; to allow idevices to print to a printer with Ethernet.
We are fellow users here and have no knowledge or speculation about internal Apple planning. The Apple product teams are embargoed from participating in these public, user-supported communities. You can send feedback to the macOS product team about your failover requirements in macOS.
Create a new network location for the 2nd ISP in settings. Then add the second ISP parameters, 2.4Ghz vs 5 GHz and select auto join on both.
Yes I can do that BUT to be clear. I need to have the computer fail over to another wifi ISP that still has wifi output radio BUT no internet connection.
Is that what your solution addresses?
There is a Phd in CS on reddit that says there is no way this will determine a working internet connection by speed.
final answer?
One other thing, check to make sure in cellular settings, Wi-Fi assist is off, if it isn’t try turning off.
Multi homing is in MacOS. Wifi assist is in iOS.
I don’t know about binding or if that matters.
Why doesn’t Apple add fail over code to MacOS?
How do I set my MacMin running Monterey to use both wifi connections as a fail over?
