Linux Distro
That's a bit confusing. Can you clarify what you mean by "old"? I'm here to help!
The version you mentioned is quite outdated and won't be supported in the coming year. You should have chosen something newer like 16.04 or 17.10. The driver situation will remain consistent either way. I currently use a Broadcom wireless adapter on my laptop, and it's functioning well with Kubuntu. If you went for 14.10, that would be even more problematic because it stopped receiving support in July 2014.
You referred to your preferred distributions such as Kubuntu, Ubuntu MATE, and stock Ubuntu (Gnome since 17.10), etc. Regarding the limited storage space, it’s likely because you’re working with a small partition size—specifically, only 5.2GB for Ubuntu. For resizing partitions, you’ll need to use the live disk environment. This should clarify your situation.
It seems you simply pressed install without choosing a partition size, and you're currently using 5.2GB.
His WiFi setup is quite sensitive. Attempting some modifications on it recently caused it to fail completely after two days of effort. That’s unusual considering I’ve been using Linux since 1996. It feels like a poorly planned mess overall. I’d steer clear of Ubuntu if I had to rely on it for WiFi, and any Debian/Ubuntu-based distros like Mint are better options. Finding one that fits your needs is what I usually suggest. If you manage to get it running, just don’t tamper with it and hope the fix stays in place. WiFi tends to be a major headache on Linux because of low-quality devices flooding the market, though reputable brands still perform well.
You won't discover any distribution that promises reliable wifi drivers for all hardware. Many chipset manufacturers, such as Broadcom, haven't been integrated into the kernel, meaning updates can break drivers until fixes are released. I once experimented with a Broadcom adapter on my laptop, but eventually switched to an Intel one after becoming frustrated.
