If you're connecting your computer to your router with an Ethernet cable, check it's plugged into the right socket on your router. If your router's connected to a modem, check your Ethernet cable is plugged in to the LAN1 socket on your modem and the correct Ethernet/WAN socket on your router.
If you've got the Plusnet Hub One, connect one end of the grey Internet cable to the DSL socket and the other to the phone socket (it's the smaller of the two). If you're using a Plusnet 2704n or a Technicolor 582n, it'll be the fourth Ethernet socket on the back of your router.
If you're using Wi-Fi, have a look at our Wireless connection guide for more help.

Here's a handy video all about how to find your master socket and how to use it.
If you've got a double master socket (one with two phone cord sockets) you can connect your router directly, without using microfilters.
If you haven't got a double master socket, you'll need to connect your router through a microfilter without using an extension cable.
If this hasn't fixed the problem, go to If you need microfilters, make sure they're working.
If you need to use microfilters, make sure they're working

If you've got a , you won't need a microfilter.
