AC3200 not putting out wifi speed it's receiving from modem

[Gillaspyjm]

Ok, so I bought a new AC3200 Nighthawk Router. It is putting out about 80mbps and inconsistent upload speeds. I hade Spectrum come out, and they tested everything. They gave me a new modem, must as a precaution, but everything is working on their end. Coming out of the line and coming out of the modem, we're receving average 500mbps speeds, but the modem is not putting out more than 100 on average. It's giving us pretty crappy internet at this point. My wife is having trouble doing invoicing and other business tasks in our home office. 

Does anyone have any idea what this could be? Is it a setting issue? I am computer illiterate when it comes to hardware, and I've never really messed with router settings outside of the initial setup and following instructions.

A couple things. 

1. what actual modem do you have?

2. what firmware is on the router? 

3. What hardwired speed do you get from the router? 

4. the R8000 has smart connect which moves devices from 2.4ghz to 5ghz. 2.4ghz is slow and suffers from interference. Have you tried disabling smart connect and speedtesting each band?

[Gillaspyjm]

I assume R8000?

I haven't tried turning off smart connect. It is current putting out two 5ghz bands and one 2.4ghz band. It doesn't seem to switch us between them without us doing it though. The tech said the 5ghz bands were outputting as if they were 2.4ghz though.

Try turning of smart connect. 

And then testing the following and report it back here. You, not the tech. 

Also put what device you're testing on. 

2.4g:

5ghz-1:

5ghz-2:

Wired:

Is that testing wired to the modem or the router?

[plemans]

both if you have time. it shows us if the router or the modem is the bottleneck

[Gillaspyjm]

The tech tested it from both, and we were receiving about 500mbps directly wired to the modem and 80-100mpbs from the router wired. 

[plemans]

Not the tech, you.
And the wireless speeds

[Gillaspyjm]

Fair enough, I can get that in the morning. Just giving you the info that I had on hand. I was standing there when he did it and showed me the output. 

[plemans]

I understand the tech did that. Many times though its done on their little handheld scanner and not test on an actual modem. 

I've had them pull full speeds on their scanner but hookup their modem and have 10% speeds. And then the tech gets confused and goes "well it should work, lets try a different modem". 

So actually testing each step in your network is key. 

If you can connec directly to the modem and get full speed, then we move on to hardwired speed with the router. Once we get that to full speed, then we move on to wireless.

What firmware version is on the router? 

Did you update the firmware? If so, try factory resetting. During the install leave access control, qos, traffic monitoring, and parental controls all disabled

[Gillaspyjm]

This is the current firmware version

[plemans]

did you try the factory reset? 
if that doesn't help, try installing version 1.0.4.28 of the firmware, then do a factory reset. Also disable auto-updates if it works. The newer version have netgear armor and there were random routers that didn't play nicely with armor.
