I have a Devolo WIFI range extender that has worked successfully over a Plusnet router. Having changed to NOWTV I can no longer control or see the range extender config using a PC based Develo Cockpit software. The HUB router is not allowing me to communicate from the router to the range extender and is blocking it. Have tried Live Chat but it timed out in the middle of me typing a reply, not a very good system. Have no idea what setting in the router is blocking communication. I already have renamed 2.4G and 5G SSID's but this did not solve my problem. Any help would be appreciated.
