I have no complaints with the Hub.
Admittedly I only use the router to run a small home network consisting of a wired Desktop, a NAS device running a continuous backup and a laptop.
I have the network configured to fixed IP's and consequently have DHCP switched off. Both machines are port forwarded for torrents although I rarely use them.
I have seen up to 80Mb/s across the network on times which definately outperforms my old Linksys WRT54G2.
I find I can pull the full 20meg wired or wireless.
As stated I am not a torrent hog so have not much experience but have used it a few times with medium sized swarms without any problems whatsoever.
IMO it's a great bit of kit.
