I'm in the process of installing 18.04 on an old macBook Pro 2009. The Ethernet connection works as it should, but the Wireless was not detected during installation, and I had to install an extra module. Once the module was installed, the wireless seemed to work fine - it detected the networks around my house, and the signal levels look right.
The problem is that every time I try to connect to a network with the correct password, nothing happens for about a minute, and finally I get "Connection failed: Activation of Network Connection Failed". If I try it with the wrong password, I get the appropriate dismissal, so it clearly talks to the routers.
Here is a link to the output of the WirelessInfo script: https://pastebin.com/ZSmxA6gU
I tried to find solutions here and elsewhere, but most threads deal with adapters that are simply not working, not ones being flaky like mine. I'll keep trying, but I am new to Linux, and there is a lot to learn before I can make sense of even the WirelessInfo output.
