Slower speeds than I’m paying for

I pay for 1000mbps but only getting around 300. I’m using a NETGEAR Nighthawk AC1900 and testing in the same room. Many of the coax outlets in my home don’t work either. Is it old/bad wiring?

Would love to know if you find a fix. Same issue with me only 2 weeks into xfinity service.

... I pay for 1000mbps ... NETGEAR Nighthawk AC1900 ...

If the device is a model C7000, it is not compatible with Gigabit internet service. Comcast/Xfinity rates it for use with plan speeds "Up to 864 Mbps". AFAIK they have never said how they provision devices operating on speed tiers they're not approved for, but many customers who tried it have reported that they don't get full speed. There's a tendency to think the device will operate at the maximum speed it is capable of but that doesn't seem to be the case.

For a device compatible with Gigabit follow the "See all modems" link near the bottom of https://www.xfinity.com/support/internet/customerowned and then under the "All compatible modems by brand" heading click the various manufacturer lists and look for devices rated for use with plan speeds above 1 GHz. Using devices on Internet speed tiers for which they are not approved tends to produce unexpected results, often speeds well below the ones you are paying for.

I previously was paying for 400mbps and was still only getting about 200 while testing. So even if my device isn’t made for 1g speeds, shouldn’t I have been getting more speed previously as well?
