The title says the main issue, my Realtek 802.11n WiFi card isn't being claimed by the drivers from here. I installed led the drivers using the install.sh script given in the decompressed tar.gz.

Why is my WiFi card unclaimed by drivers in UbuntuMATE?

I've just found out that your chip is actually rtl8192eu. As far as I know, there is no driver for it in Ubuntu's repo. However, as v0yAgEr mentioned on OSMC forums, there is driver for that chip works for kernel version 3.18 on GitHub. I modified v0yAgEr's tutorial to a way hopefully would work for you:Install build-essential:From the computer have Internet access, go to Ubuntu Packages, download build-essential, its dependencies and its dependencies' dependencies to a folder called bldessenCopy that folder to your Pi, then install all the debs by sudo cd bldessen && dkpg --install *.debDownload the driver from GitHub (click the Download Zip button), copy to your Pi, then extract it: unzip rtl8192eu-master.zipCompile your driver:cd rtl8192eu-mastermake ARCH=armsudo make ARCH=arm  installsudo bash -c 'echo options 8192eu rtw_power_mgnt=0 rtw_enusbss=0>/etc/modprobe.d/8192eu.conf'Test if the driver loaded:modprobe 8192eumodinfo 8192eu
