Mae cynllun grant Allwedd Band Eang Cymru ar waith ar gyfer yr ardaloedd hynny nad ydynt yn dod o dan gamau cyntaf prosiect Cyflymu Cymru. Mae hwn yn rhoi hyd at £1000 tuag at gost dod o hyd i ateb arall i anghenion band eang eiddo na all lwyddo i gael mwy na 2Mbps.  Mae’r eiddo preswyl a busnes sy’n manteisio ar y cynllun yn cael cyflymder lawrlwytho band eang cyfartalog o 10Mbps, o’i gymharu â chyflymder o dan 2Mbps cyn y grant.
For those areas not covered by the forward roll-out plan of the Superfast Cymru project, we operate the Access Broadband Cymru grant scheme.  This provides up to £1,000 towards the cost of an alternative broadband solution for premises which cannot achieve more than 2Mbps.  Those residential and business premises benefiting from the scheme are experiencing an average broadband download speed of 10Mbps, compared to a pre-application download speed of under 2Mbps.
