I have recently switched my ISP from BT to SKY.

When using BT, I had my PC plugged into LAN 1 on the router and a TL-PA4010 in LAN 2. I had 2 other TL-PA4010s paired with the one connected to the router to provide wired connections in other parts of the house. Everything worked OK, as well as the tpPLC utility that gave me a schematic of the adaptors.

On switching to SKY, I've reset the adaptors and paired them again and they all work OK with one of them in LAN 2 and my PC in LAN 1. However, the tpPLC utility now does not find the adaptors. The TP-Link chat line agent said that this was because my PC needed to be be plugged into an adaptor rather than the router, but had no idea why it worked previously. Has anyone got any suggestions to make it work as I'd prefer the PC was plugged directly into the router.
