In the end I found that as long as the AV2000's were on the same fuse I got ok speeds out of them. As soon as I moved them to a different circuit the speed plummeted. Sadly, where I wanted to use...

Thanks - I'll keep an eye out for updates! I've managed to get acceptable results by moving units between different sockets and trying different combinations of AV500 with them!

Model : Hardware Version : Not Clear Firmware Version : ISP : I have 2x AV2000 and 3x AV500s. The idea was to replace 2 of the AV500s with the AV2000s - but the link between the AV2000s is slower...
