Yes I have tjchan! Although I don't believe the 2Wire HomePortal 1000HG will get anymore updates. Btw, I get the HomePNA working again for now. All I did was to put it in another USB port. I have 4 USB 1.1 and 4 USB 2.0 ports on that computer. The HomePDA 2.0 works on either. Although it only runs at 12mbps (1.1 speed) anyway.
I do have many other computers on the network and none of them have any problems and are solid as a rock! Except these two of course. Both are HP Athlon 1.2GHZ ('02 era) which I believe HP used spare parts to make them (each one is a bit different and I have seen 4 of them) and sold them off to TigerDirect as refurbished. They work fine for the most part, but they are also very quirky on the other hand.
