I am trying to set up a tp-link router to replace my EE brightbox. I have plugged it in and plugged it in the phone socket, switched it on, all lights have come on. I have plugged a LAN cable from the laptop to the router to set it up. I clicked on the wifi in the taskbar and clicked on the tp-link, put the password in and clicked connect. It now says disconnect although it also says No internet, secured. I am supposed to go to the website to set it up but how can I when there is no internet connection? I have tried but the page won't load, even with the LAN cable connected. How do I set it up??
