    No Wifi, before and after upgrade
    I have a 1-1/2 year old Mac, AIO, which worked fine on my old WiFi setup. It has been a year since I moved and my Mac and Mac Pro both have been out of service since then.
    I fired up the Mac and everything works but the wifi connection. It sees all the local wifi in my apt building and I can connect to them and the password option pops up, but not on my Mac and MacPro. I can click on my wifi and it sits there and spins, then it want to run diagnostics then has no mention of a good fix. Only the Mac and the MacPro are giving me the problem, two ipads and two iphones work no problem. I am using the Spectrum router. I have not hooked it up direct yet. So others in my building are using the same router, and I can connect to theirs. But I cannot connect to mine. So it is my network and only these two mac's
    I did install Mohave last night using the ipad hot spot through WiFi, but after the install, nothing has changed.

    Welcome to our forums.

    We're trying to understand your setup? Is your apartment building equipped with free WiFi or do you have a separate connection that you're paying for? The reason we ask is because you mentioned that you have a Spectrum router and others in your building are using the same router, or do you mean that they have separate routers?. Spectrum setup usually consists of a modem and router but sometimes they can be encased in the same unit.

    Why don't you try to connect your Macs via ethernet direct to the Spectrum router to see if that works?

    Also... you may have to clear out all old connection information and network options on your Macs before trying to access the new WiFi from your Spectrum router. Since you haven't used those machines for a long time, all the old options and connections are likely still in memory. You will have to set them up as new connections. You probably need to access the internal menu of the Spectrum router to assign a SSID and password. Check your Spectrum manual or give them a call to learn how to access the internal menus on the router-modem. The router-modem will have a userid and password assigned to it. Normally the userid is "Admin" and the password is the same. But you need to check with Spectrum to make sure.

    As a followup, I did clear out old wifi beforehand, I have not hooked up direct and this is a new network and my windows based and "I" based computer/devices work fine, the Mac and Mac Pro do not.
    This afternoon, I defaulted the router to new. I had no problem with the windows and I units, but the mac and MacPro still do not connect.
    On the Mac, the airport icon is faded, but it can still see all the networks in my building, and each tenant has their own router, when I click on my network WiFi, it searches for it and then goes back to diagnostic testing.

    Please backup. Everything has a life cycle, unexpected and warning free. Nothing will last as long as you want it to.

    when I click on my network WiFi, it searches for it and then goes back to diagnostic testing.

    I don't know if it's the same thing, or if Mohave still uses Wireless Diagnostics.app, but I would give it a try if it's still there. Just hold down the option key then click the airport Wi-Fi Icon in the menu to access it. Then just follow directions.

    It may come up with something.
