Cader NetworksBroadband and VoIP across Gwynedd
From the Menai Strait to the Mawddach Estuary, Gwynedd is half coast and half mountain. Broadband options shift just as much: fibre in Bangor and the Llŷn towns, 4G across the valleys, Starlink for the slate-quarry villages and hill farms.
What we install across Gwynedd
Gwynedd covers more terrain types than almost any other Welsh county. Coastal towns along the Llŷn, slate-mining communities in Blaenau Ffestiniog, the Bangor university and hospital corridor, the deep valleys of Snowdonia. Fixed-line broadband reflects all of it: excellent in some pockets, genuinely poor in others.
FTTP coverage is good in Bangor (especially around Penrhyn Road and the university), Caernarfon town centre, Porthmadog and central Pwllheli. Dolgellau and Tywyn have improving FTTP. Outside those footprints, most of the Llŷn peninsula villages, the Snowdonia foothills and the slate villages from Blaenau Ffestiniog through to Bethesda fall back to FTTC, 4G or Starlink.
We do a lot of work in Gwynedd's holiday-let market: cottages along the Mawddach, harbour-front properties in Aberdaron, farm-stay accommodation in the hills above Bala. The pattern is consistent. Guests want functioning WiFi for streaming and video calls. Owners want a simple management story. We size 4G or Starlink to fit.

Coverage questions for Gwynedd
Which Gwynedd postcodes do you cover?
LL35 to LL40 (Tywyn, Dolgellau, Barmouth, Aberdyfi), LL41 to LL48 (Blaenau Ffestiniog, Porthmadog, Pwllheli, Llŷn peninsula), LL49 to LL58 (Caernarfon, Bangor, Bethesda), plus SY20 on the Powys/Gwynedd border. Some borders with Conwy by arrangement.
Do you do Starlink across Snowdonia?
Yes. Snowdonia (Eryri) is one of the areas where Starlink genuinely shines. Many properties up the valleys are signal-blocked from all four UK mobile networks. We have installed dishes in places that have never had reliable broadband before.
Can you handle multi-site holiday-let businesses?
Yes. Several Gwynedd customers run 5 to 20 holiday cottages across the county. We standardise the router and access-point setup, give the owner one number to call when anything is wrong, and keep central billing simple.
Is the Access Broadband Cymru grant available in Gwynedd?
Yes, for eligible properties currently below the speed threshold. The rural belt of Gwynedd has more eligible postcodes than the coastal towns. We handle the application paperwork alongside the install.
