I am having issues with updating the firmware of my deco's. I only recently noticed I needed to update my deco using the web-interface. However I am unable to connect to this interface using either tplinkdeco.net or my LAN-IP. I use the deco in acces-point mode with a seperate (non TP-link) router. When I enter the link or IP-adress the website does not load at all? I have tried connecting both wireless and wired to the main Deco. Anyone have some suggestions?

Thanks in advance
