Title: Not as good as HPNA
Review: I've had a phoneline network running for a couple of years with no problems, but Linux support for HPNA NICs is difficult so I needed a second bridge to link Cat-5 hubs. Two of these powerline bridges were cheaper than another HPNA 2.0 so I tried converting over. ... Our big house must have even worse power wiring than our screwy phonelines, because the bridges couldn't maintain a connection more than a few rooms apart. They worked about as well as HPNA 1.0 did, which isn't good enough.
