Cader NetworksBroadband and VoIP in Anglesey
Anglesey, Ynys Môn in Welsh, is a county of its own — connected to the mainland by the Britannia and Menai bridges. Connectivity in the main towns is improving fast; the rural centre of the island is still where we do most of our 4G and Starlink work.
What we install across Anglesey
Holyhead, Llangefni, Beaumaris and Menai Bridge town centres all have viable FTTP. The rural inland — Bodorgan, Llanerchymedd, the lanes towards Cemaes Bay — is much more mixed, and most of what we install out there is 4G fixed-wireless or Starlink.
For Holyhead we handle the port-side businesses, the high street and the residential streets towards South Stack. Beaumaris and Menai Bridge are similar: FTTP through the centre, 4G or Starlink as you move out towards the coast.
Inland — Llangefni, Bodorgan, the central farmland — is where most of our 4G and Starlink work happens. EE and Vodafone signal is strong across most of the open island; coastal and dipping ground varies. We check at your postcode before quoting.
