Macbook pro not connecting to my home wifi

Go to System Preferences

Click Network

Highlight AirPort and click Advanced...

Select your access point and Remove your access point with the minus (-) button.

Launch your keychain access in Utilities and delete your access point keychain entry.

Reboot

Instead of joining it from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed. Before I went through network diagnostics and all of that stuff in system preferences, and then I tried the "Join Other Network" method, and now it works like a dream.

Perhaps you are connecting to the wrong network (Neighbor’s with the same SSID)

I see “Connect Automatically” selected. Unselect it.

Turn CapsLock Off

With an SSID (Name of the Network) not being broadcasted it could be Wireless A (2.4 GHz), B (5Hz), G(5HGz), or N(2.4GHz,). So, click on the network icon > select “Other...” > manually enter the information: [ Network Name] and then [Password].

If you hold the mouse button on the Wifi icon, how many SSIDs show up? And the strength bars?

With all the wind in my area, I got the same error. So, I had to call my Internet Service Provider. The automated service ran me through how to fix this. It is interesting and quite user friendly.

So, as I did, find out how to contact your Internet Service Provider; contact them; ask them about this automated method; then give it a go.

Even with join other network its the same thing. There is a popup saying my network requires a wpa2 password.

Was that even after selecting WPA2 & filling in the password?

Oh, have you changed the Password recently to join it?

Long shot...

I've been debugging a problem with my VPN client constantly reconnecting, along with poor WiFi performance. After much digging, I came across an excellent article - although written for Yosemite and iOS8, it still seems to be relevant to Mojave, especially with a newer WiFi chip in the 2018 MacBook Pro. https://medium.com/@mariociabarra/wifriedx-in-depth-look-at-yosemite-wifi-and-awdl-airdrop-41a93eb22e48

The author wrote a program that essentially just issues a command and keeps it enforced. You can try it manually in a terminal window: sudo ifconfig awdl0 down

To reverse the command, type: sudo ifconfig awdl0 up

He gives a great technical explanation, so I won't repeat it here. The command disables a virtual network interface that's used for ad-hoc WiFi by features like Airdrop; I personally won't miss them. So far, I've gone from losing my connection 20 times an hour to being stable for 3+ hours.

A mix up on my part:

• Wireless A (5GHz)
• Wireless B (2.4GHz)
• Wireless G (2.4HGz)
• Wireless N (5GHz)

With a Wireless AC (Purchased Off-The-Shelf today) router, it’s manufactured with builtin dual-band (2.4GHz & 5 GHz). So, as long as your broadcasting the SSID, any Wi-Fi enabled device will see it.

So, locally connect your Mac to the Router using an Ethernet cable (and a converter, if necessary) and see if it connects. If you are the Administrator of your network:

• Open your Web browser
• Go to the Default Gateway: (type either 192.168.0.1 or 192.168.1.1 in the address bar)
• Press enter
• Use the log in information (User Name and Password)
• Press Enter
• Verify the computer names of your network

Maybe, just maybe, you are connecting to a network by the same name, on the same router, but being broadcasted through use of a different frequency.

Be wary of those spoofing your SSID; you wouldn’t want to connect to another person’s router.
