I recently installed Ubuntu Mate 22.04 on an old Macbook I own which I think is a mid 2008 model.
I'm not very knowledgeable when it comes to linux (or macs) but everything seems to run fantastic with the exception of wireless connectivity. The drivers are installed according to the os and it also connected to my wifi but when I try to use the internet everything timed out. Ethernet on the other hand works or at least used to cause after numerous attempts at trying to "fix" it I'm pretty positive I managed to break it further. Webpages no longer time out they just say that there's no internet connection. That's basically the whole situation, I think I just made it worse with my asinity so instead of completely wrecking it, I decided to ask for some help from the community.
Edit : I reinstalled the os and no luck both wifi and Ethernet are busted. Ethernet never connects and wifi always times out. However plugging an external wifi card does work.
