Seems like they're saying that gamers would prefer wired to wifi, which I think is reasonable - it's not so much a bandwidth issue as a latency issue - wifi has higher latency, and higher variance than wired ethernet, especially if you get a crappy client joining and filling up the airtime with retry attempts. But maybe that's dominated by ISP variance for most.
