Usually, a simple Factory Reset resolves most connection issues.
Before you begin
Make sure you leave the router turned on. If it is turned off, turn it on and wait until at least the 2.4GHz and 5GHz lights are on.
A Factory Reset will clear any custom settings or router changes you've made. The router's WiFi channel names will default back to their "out-of-the-box" names as will the Network Key which will default to the PIN Code found on the base of the router. Okay, we're ready to go.
1/. Find yourself a paperclip, toothpick or something similar
2/. If it's a paperclip you found, open it like this
3/. Now locate the RESET hole at the back of the router. Push the paperclip into the hole and hold it in for at least 20 seconds
4/. After 20 seconds releace the paperclip and eventually all the lights on the router will go out. Shortly after, the power light will come on. After arount 1 1/2 minutes the first four blue lights shuld be on.
5/. Attempt to connect to the router over WiFi or Ethernet cable and browse to a website. If you still can't connect, please give one of the team a call on 0800 862 337.
