Earlier quoted context omitted.
Maybe it's because I'm always setting up with a home router, but I haven't had to install anything for my last three internet setups. I wasn't even asked to for this last one I believe. The tech just made sure the modem was working properly and he could get a solid connection from it, and then I plugged in my router and was good to go.
I recently upgraded my Fios connection and when the tech replaced my router he asked to install some software. I was currently booted into my Linux partition at the time, so he basically said "oh, well" and everything worked fine out of the box. It's likely bloatware.
However, they only have Windows and Mac versions of the stuff.
