My broadband keeps going off

[#1]

Every now and again my internet connection goes off and a page comes up saying "No Broadband found"  The light on the router flashes and goes red for a minute then comes back again. Could somebody please look at my connections.
Thanks.

Hi maryf,
It's very likely that your connection at your Local Exchange is being dropped for some reason. Can you confirm if this issue is still apparent whilst your router is connected into your Test Socket with an alternative microfilter?
Although it appears that the connection is dropping at the exchange, this could be being caused by faulty internal wiring or hardware so the checks above will rule this out for you.
