My freshman year roommate was pretty good. I suppose that means I was the “bad roommate.” My most egregious offense was probably printing out papers at 2AM while he was sleeping. I don’t know if I woke him up or not, but this was back in the dot-matrix age and those puppies are loud. He never complained about it though.
I hope this isn’t seen as picking on you GameHat, but I did Let’s go to the quarry and throw stuff down there at the notion that “even back in those days there were networked computers and (limited) wifi”. Back in what days? The late 1990s? Like, 10 whole years ago? It just struck me as funny because when I went to college (mid 1980s), computers weren’t networked at all (if you could even find one to use) and wifi was completely non-existent (it hadn’t been invented yet; any “online” stuff you wanted to do was done on a regular dial-up phone line at 300/600 baud; 1200 if you were lucky).
Like I said, not picking on you, but it does amuse me to hear “back in the day” used for anything so recent that a kid who’s not old enough to have a driver’s license would remember it. Thanks for the laugh. 
Anyway, to carry on with the college roommate stories: I had a roommate in college that smoked, in our dorm room, constantly (I’m a non-smoker). He’d go to sleep smoking (he’d stand the cig up on it’s butt to just smolder until it burned out) and he’d light up first thing in the morning. When I asked him not to light up if I was still sleeping, he’d comply… until he was about to leave the room, then he’d light up and BLAM! the door behind him.
I had another roommate who decided that crack, which was a new thing at the time, was a hobby worth pursuing. That ended the night I came home to discover $400 cash missing from my room. I got my money back in a few hours, but the next day while he was out I put all his stuff out on the lawn and had a locksmith change the locks (the lease was in my name only).
Since then I’ve had a rule: no roommates unless we’re boyfriend-girlfriend. And even then I’m cautious about co-habitating, since I’ve had some problems there as well (like the alcoholic girlfriend that kept her big shiny sewing scissors on her nightstand for when she did needlepoint; I had reason to fear that she would stab me while I slept).
Currently I only share my house with my 3 feline overlords. They can be a pain, but not nearly as much of a pain as a human roomie.
I’m talking early to mid 2000s. Started college 1999, graduated 2004.
You think I’m being “young” with “back in the day”, but consider -

[li]When I started college, probably less than 20% of students had cell phones[/li][li]Nobody had ever heard of texting[/li][li]There was no Facebook[/li][li]No Twitter, either[/li][li]No Wikipedia. God, I think school would be easy if I had to do it again, just because of Wikipedia.[/li][li]Wifi was an exotic beast - a few places had it, but most didn’t[/li][li]Proper academic journals - there was some limited online publishing, but for the most part I still had to go to the (physical) library and pull (physical) journals off the shelf.[/li][li]I had to “learn” Excel, as I had never been exposed to it in HS[/li][li]Similarly, even e-mail was a bit new when I entered college.

I’m only 30, and things have changed really, really fast. Information moves so much more quickly, even from when I graduated just eight years ago.
