Though Zyxel advertises the PLA-400's theoretical maximum throughput as 200Mbps, our Labs' test showed actual throughput to be much lower: an average of 35.56Mbps. This is an improvement over the PL-100's throughput but still behind the 52.7Mbps posted by the Netgear HD Powerline Ethernet Adapter. Still, 35.56Mbps is more than enough throughput to stream HD content to your home entertainment system.
Zyxel supports the PLA-400 with a limited two-year warranty. Phone support is available weekdays from 8 a.m. to 5 p.m. PT, and Zyxel has improved upon its previous support line by offering a toll-free phone number. You can also fill out a form on Zyxel's Web site to request assistance from tech support.
