    I downloaded and installed a fresh install of OS Mojave, but ever since then I am getting wifi issues which I can't seem to resolve.

    I could be using the machine fine, as now, wifi is connected but then decides to loose the connection without disconnecting. I have tried to remove (forget) the network and reinstall, that didn't work, reset the PRAM and NVRAM that didn't work. Changed channel on the router and separated out 2.4 from 5ghz that didn't work.

    None of the other machines that have not been upgraded have been affected, the iPhone works fine too, just this one I have upgraded so far.

    What else can I do?

    Which wifi router are you using?
    You mention that you split the network to 2.4Ghz and 5GHz, but you don't say which one you're using. Does the same thing happen on each?

    How can it lose the connection without disconnecting?
    What are the other machines that have been upgraded?

    Need more details. Way more. :)

    See my other posts on this subject. I believe there is a WiFi problem with Mojave 10.14.2. Rebooting has allowed me several hours of WiFi use so far.

    I’m running 10.14.2 and my wifi has been rock solid. 10.14.3 came out today though, might be worth a shot.

    I’ve been having the same problem with my 2018 mini. Intermittently loses abuility to connect to Internet while still connected to wifi. No fix sticks. Talk of USB/radio interference but I wonder about a software glitch too. On 14.2. No problem with my MacBook Pro at the same desk connected to the same peripherals.
