No internet despite being able to connect to network / 16.04 LTS / 2008 Black Macbook (Blackbook)

I'm trying to breath some life into an old macbook of mine and I thought I'd do that with Ubuntu 16.04 LTS 32bit. Everything seems to be running fine but I'm unable to connect to the internet via wifi.

I can see the network menu, I can see my wifi and I can even connect to my network. However I can't 'connect' to the internet.

I've had a good look through Ask Ubuntu and Google'd my problem but I can't seem to find a result that works.

I've looked at what wireless card I have, checking the card against the correct driver, making sure all the right drivers are installed but still nothing.

Fortunately I'm still able to connect to the internet via eithernet, so I can still download updates and drivers at least.

Granted I'm very new to Ubuntu I can't figure out what to do. Some help would be very much appreciated.

It's not soft or hard blocked either.

rfkill list all

Extra information, hopefully this can help. If not I can always provide more. Cheers for looking.

Ok... I feel like a fool. All my wifi problems for broadcom were solved with one command found here

That command was

sudo apt-get purge bcmwl-kernel-source broadcom-sta-common broadcom-sta-source && sudo apt-get install b43-fwcutter firmware-b43-installer

Thanks anyway.
