Wifi adaptor hell and back . Any help appreciated

Hey guys. Recently decided to get rid of Windows 10 and move onto Linux mint. All was going well until I realised that my WiFi adapter apparently doesn't work with Linux (even though there's a Linux file on the install cd rom) I've ordered a new one which specified it could be used for Linux but somehow can't find any way to install the drivers off the disk. I've tried plugging it into ethernet and using driver manager both times and have got nothing. I have tried fiddling with the files inside the driver disc and got round to an install.sh file. However I can't change the permission to execute as it says its read only. Does anyone have any ideas on a fix? Was really excited to start learning computers through Linux and am confused so early.
The two wifi adapters in question are.

XVZ USB WiFi dongle for PC 600Mbps dual band 2.4GHz/5GHz
&
Foktech Wifi Dongle, AC600 802.11ac Dual Band 5GHz Mini Wireless Network USB Wifi Adapter

Thanks again for any help!
