I used to be on wireless, because Telstra (former national carrier, was privatised without being broken up, instantly established an unshakeable monopoly - typical Australia) sets arbitrary line attenuation limits and since they own the lines all the other ISPs have to obey. I was literally 50 metres too far from the exchange. The only net I could get that wasn't dialup or satellite was wireless from the nearest line-of-sight tower, 7km away across a bay. There was a tower literally like a kilometre and a half from my place but there was of course a fucking mountain between me and it.
Because I was on the very edge of the line-of-sight tower's range, my net kept trying to hop to the closer tower, which of course it couldn't actually see, so I'd lose my internet for anywhere between a second and several days and the guys my ISP sent out to unfuck it never figured out how to stop it from happening. Basically, for two years I could lose my net at any time for any length of time. I learned to appreciate the whole days or weeks where it went without dropping. In hindsight it's a wonder I was able to get any decent gaming in at all, but I had some of my most enjoyable times in Project Reality and ArmA 2 during that period.
Now I just have five shitler housemates who torrent TV shows all the god damn time.
