I would say to find a place where you can attach the ethernet adapter. The problem with your wifi adapter is that it's drivers are not in the Linux kernel, so, while you can certainly download the drivers, copy them to a usb stick, then, copy them into the computer, this is a much harder way of achieving what a few simple commands will do if attached to a wired network.

BTW - using Mint if your new to Linux is a good choice. If you going to do your first install, Mint should have everything running right out of the box. It may even have a pointer to the driver of your wifi dongle. Although, like I said, searches have found that dongle to be problematic, so, having a wired connection will make the installation of drivers a lot less frustrating.

Don't stick with Fedora because I use it or this is a Fedora thread. If you like Fedora, that's a different story. The only reason I can give you the help on your wifi is because I've searched the fedora forum threads looking for folks who have that same wifi dongle and have looked for solutions.

I'll give you a hint on Google Foo. I Googled the ID part of your wifi string, that is, "ID 0b05 : 1784", when you first posted it, and found many threads asking for help. The Ubuntu forums had many threads, but, I guess that's cause it's the most popular. So, whether your distro is Fedora, or, a Debian based distro like Mint or Ubuntu, there are possible solutions.

Fedora has something called the akmod's, which allow you to build a driver automatically when a new kernel comes in, or, just to build a module on an existing kernel just by rebooting. I think Debian uses dkms for a similar purpose. If you install the driver from the rpmfusion repo, then, install the akmod-rt3070 app, rebooting should build the driver for the kernel that you are using. I know this sounds technical, but, it's really not that hard to understand once you get used to it.

There are no guarantees though, the wifi chip in your dongle is not that Linux friendly, so, while we may get it to work, it may be hit and miss as to how well it works. Just let us know when you need more help, we'll be here. Also, be patient, sometimes we're at our day jobs and don't have an opportunity to respond right away,

OK, but, I just realized we don't have a Mint section ... how'd we miss that? So if you want to post here or in Ubuntu or in the Just getting started section ... wherever, we'll see you.
