Those actiontec homeplugs came in this afternoon, so I hooked em up and tried them:
saturates my cable connection, but so does wifi
xferring a c. 260MB file I was getting c. 5300KB/s w/"ethernet"(homeplug, realtek 1G port on desktop, not Intel)
versus about 3900KB/s using 2.4GHz wifi N on the same machine. (I'm getting nowhere near their 500Mbps mark, but I'm still happy with what I do get as it beats running ethernet with 30' of cable.)
x-fer rates were pretty stable...
So, I'm pretty happy with those plugs... now to get a wifi homeplug for the garage(detached, but has had power run to it)...
I also got my wifi and ethernet USB dongles, but I won't have time to test them on either the mk802 or OE today.
[EDIT2]
BTW: the file xfers were between my nb(MSI GT725/P8600/4GB) running Ubuntu 10.04 LTS, 5GHz 802.11n wifi (108Mbps linked at the time) to my Netgear N600(WNDR3400v2) router connected via 100M ether port to one homeplug. Second homeplug in next room connected to my new desktop(ASUS P9X79/3930k/16GB) Realtek(NOT Intel) 1G ether port. Used winscp under windows 7 x64, sftp connection.
So, it's lik ethis:
Desktop <--cat5 ether cable 100Mbps--> homeplug #2 <--home power run theory 500Mbps--> homeplug #1 <--cat5 ether cable 100Mbps--> WNDR3400v2 <--802.11n 5GHz 108Mbps--> notebook
Did the xfer w/the nb because it was up, wired servers are off ATM, one needs a new CPU, and the other doesn't have much storage ATM and nothing that I need immediately(used to serve as my router back in the day along with 2 PCI ether cards, 100M switch, and a linksys b/g AP. when my airport crapped out on me(original one, so I just recycled the PCMCIA wifi card in it(yes it actually had a PCMCIA wifi card to do 802.11b) for my newton...).)

[EDIT]
according to reviews and testing that I have read those plugs in IDEAL conditions can get about 100M ethernet speeds...
