Your internet signal arrives via a coax cable. Is it attached properly? If you are able to twist it by hand, it's best to tighten it. Use an open-ended spanner and tighten your coax cable as tightly as possible.
Is your cable tight and the problem is still not solved? Then reset your modem. You do this by unplugging the lead from the mains socket for 15 seconds. You can also perform a reset via My BASE. Choose ‘modem settings’ and then click ‘restart modem’.
Is your coax properly attached, have you reset the modem and are you also having problems when internet via a UTP cable? Contact us.
