Can anyone recommend a wireless HomePlug (HomePlug Powerline Alliance - Wikipedia) device?

Requirements:
All setup (including password) can be done on Linux -- preferably html interface
HomePlug AV standard (plan to use MythTV and VOIP)
Wireless end also has at least one Ethernet port
Wireless power can be turned down (my eTEC router has wireless power level options of Full, 50%, 25%, 12%, 6%)

Any help, pointers, ideas much appreciated.
Thanks
Alan
