A Talk Talk engineer replaced my router today with a new WiFi Hub 2. I logged on to the router to change the network name and password. When I pressed the SAVE button, nothing happened, but the router status was then showing "Disabled" . I clicked the slide to enable it, but this was not successful. I was advised on a live chat to use the factory reset button, which successfully restored the router. I would like advice on what went wrong and how I can change my wifi network name and password without this happening. I asked the question at the end of the WhatsApp chat, but got no reply.
