[plug] Wireless-N router for faster wireless....

[William Kenworthy]

Encryption has overhead which can drastically cut into the available
throughput.  Further, cheaper 802.11 devices (mainly older ones Ive
looked at) can get cpu bound (or results that look like that) that also
seem to cut throughput.  These issues (the available embedded cpu's at
the time) were why WEP was originally specified, even though they new it
was weak even as the standard was ratified.
