I have a couple of Netgear powerline adapters used around the house.. XE102, etc - and was reading some interesting threads on the Netgear forums concerning all these powerline products not working with Windows 7...
Can't quite figure out what Win 7 could do that would cause an Ethernet port on the laptop/PC to not work with the powerline adapter - and yet XP works fine -
hmmm - wonder if it's not really Ethernet, but a little higher in the stack and maybe something with TCP/IP and the end to end connection ?
Anyway.... just seemed really weird -
