I've been using ZYXEL PLA-401 v1 Homeplug adapters for years to connect various devices to my router for a "more stable" than wireless connection. This worked fine in my last house, connecting a switch in our office to the router. We've now moved and I have got some more homeplug adapters to make a few other more reliable connections.
Problem is, the new adapters can't see the old adapters on the homeplug network. They can see each other, as can the old ones. I suspect a firmware or network name mismatch - I've tried to change settings on each of them but the Zyxel utility doesn't appear to do much. I can't set the DAK names, nor can I change the network names. The firmware update utility doesn't work on Windows 7 (gives a cannot find Windows path error).
Does anyone have any experience of using the Zyxel configuration utility and firmware upgrade tool on Windows 7 / Ubuntu?
