For 2.4 GHz the maximum speed you will see is 100Mbps,  80 is about the average you will see on consistant basis.  For 5GHz there are a few things you would want to check.

1.  Are you up to date on the firmware?

2.  Is there any network interference?

3.  Is your modem a gateway or just a modem?

4.  Have you attempted to reset and reconfigure the router?  

1:

My firmware 

Is 1.0.10 build 20190517 rel.65170

2:

Ive used the wifi analyzer app to determine which has the least amount of wifi interference 

3:

Its just a spectrum modem

4:

No

@rippspeed1 

Go to Advanced - System Parameters.  Then look at NAT and disable NAT Boost.  Power cycle the router and then retest the 5GHz speeds and let us know the results 

nothing ... now the 5ghz is a solid 160 to 170mbps 

wont hit higher than 170mbps

Sorry for the delay if we are not tagged we don't get notified of a response and it may take a short time for us to review overall replies.  We will need a few test preformed

1,  Test the speed and record the link rate at 5 feet from router

2.  Repeat at 10 Feet from router

3.  Repeat at 20 Feet from router 

4.  Repeat at 40 Feet from the router

Please run the test 3 times at each increment and use the same test server and test program.  Make sure to provide the link rate at each disatance and the upload and download at each increment. 

We also need to know:

The Make and Model of the computer and the OS version

what test program you used and which server.

Best Regards.
