As an update, after spending considerable time trying to integrate the PA7010P with my existing WPA4220 and finally getting them to pair the whole network is very unstable with internet access lost....

Ok I ve got it integrated now perseverance pays off. The models were PA7010P and WPA4220

Model : Hardware Version : Firmware Version : ISP : I am having no luck with adding AV1000 to AV 600 by using the pairing buttons or using the tp-link utility any suggestions please. chrismmm
