No problems on my PC with wireless internet for every online game. TP-link adapter and virgin superhub (60MB connection) and there is like 5 devices connected wirelessy and 1 device hardwired.
Although I would much rather be hardwired instead.
Yeah, I've never had issues with my wireless for gaming. Only time I've seen rubber banding is when the entire servers pings spike and thats when a big number of players complain about it. Apart from that and it's pretty rare, I've never had it, nor have I had any crashes with it. It's as fluid as I can tell and thats with a USB adapter. My routers and hubs usually have 3 - 6 months uptime.
So I can only say wireless gaming is evil.
Though I could do with a sofa, my seat is pretty hard. My backside is all tingly after a while due to the hard foam.
