I've recently installed Ubuntu 17.10 on a Macbook Pro (Mid 2012). It's not dual boot so is my only os. I've noticed a few problems with the internet connection, the first being that I am only averaging around 20mb download speeds when I was receiving my usual 80mp/s on Mac OS and this is still the case when doing a speed test on my iPhone and android tablet.
The other issue is that my wireless internet connection will die after awhile, sometimes after 2 mins, sometimes 2 hours, requiring a reboot to restore the signal.
I'm quite computer literate, but linux is completely new to me so when searching for solutions, although I can find similar problems, I can't seem to find a solution for my particular wireless adapter. Is there anybody willing to reply with a step by step guide to a solution? I would really appreciate it. I'm enjoying my linux experience so far, but this has put a huge dampener on my enthusiasm and I'm considering switching back because of it.
Running lspci -nnk | grep 0280 -A3 gives me the following.....

iwconfig gives me.....

lo no wireless extensions.
I do have another problem setting up a dual boot with windows, but I'll leave that to see if I can get a solution to these issues first.
Thank you all in advance....
