Hawaiian Tele Gigabit Fiber

[AinaAKai]

I forgot to mention, the max run of a 5E cable for gigabit speeds is 328 feet.  It's possible your cable run might exceed that as you said the house was "wired" with it.  You should try a high quality cable with the shortest distance to the router as possible.

Well... It actually is brand new CAT 6 on the long run from the fiber modem (which is in my garage) to the patch panel under my house. It goes kind of deep underground through conduit.

The house is then wired with 5E to all the phone jacks. Then, the patch cable is CAT 6 again.

I suppose there could be some translation issue between the CAT 6 and 5E. I can't remember the exact length of the total run, but it should be well under 100M. 

The speed I get is a very consistent 660MB + or - 15MB or so on speedtest.net.

What is the router brand and model? Does it even support gigabit speeds?

Other than that, why do you think that speed is needed? I have had the 500x500 plan for the last couple of years. Nothing is ever "slow" even with about a dozen cameras around the property sending data up to the cloud, constantly. I think they no longer offer the 500x500 and now it is 500x300 for new signups, which is still plenty.

Also, does your laptop/desktop even support gigabit speeds?

Yes. The motherboard has two gigabit ports 2.5GB Realtec and 1GB Intel) and my router is a Deco X20 which has a gigabit port and it connects on either NIC at full 1000Mbps. No speed difference on either. I would rather get the gigabit because with that I get a full 300Mbps uplink, but I don't want to pay more (than the 750 package) when the fastest downlink I can get is in the mid-high 600's.

I realize that I won't really see that big of a difference in most things but the cost is so minimal between the two options that I would prefer the best offering. Plus it is frustrating that there is something wrong causing me to have a slower speed.

For the past 10 years I was using a 4G-LTE router and getting like 40-60Mbps and 70ms pings and then, within 3 months, both TMobile home Internet and Hawaiian Tele GB were both available.  The TMobile was a big upgrade from 4G-LTE by the way if you can get it. All my downloads were in the 160Mbps range where I live. As soon as fiber was available I jumped on it. It probably added $50k value to my house.
