Then, of course, you are contending in your own house for wireless channel space! I'm not adequately au fait with the wireless buffering in the router to know whether contention occurs there. My maths / queing system "sense" tells me you'll have less contention if you set the N speed lower. I believe the benefit comes from being on the "rarer" 5 MHz bandwidth.

I don't think what I've said is utter bollox - but I'm not totally certain of myself here. It's just what I'd be trying (and no doubt will have to one day).

EDIT: http://www.iis.sinica.edu.tw/~cclljj...IEEE802_11.ppt might be an interesting read on the topic. It's pre-802.11n but the issues are identical.

One of my lines of thought is that downloading is constrained to 50 mbps from all sources; this can be punted into the router (depending on model) at up to 1 Gbps. You've got your wireless N set to 300 Mbps - so there's potential for buffering at 1 Gbps input. Then the router punts that out at 300 Mbps (instantaneous). In the meantime, the other download is contending for the router's resurces and buffers and ultimately the wireless channel space. Something like that.
HTH.
