I just upgraded to 1Gig on Optimum with Gateway 6. The Arris G34 will not go above the 400 Mbps that it always has. The website shows the G34 works for 1Gig. It will not! Optimum said the G34 was not compatiable. The modem needs to be a Gateway 6. They send me a new Altice 500g5 Gatgeway 6 and works correctly.
