AXE 16000 slow upload speed with 3Gb connection
I have 3Gb service from Wow!, and they furnished me with an AXE 16000 router so that I could get the full speeds. I am currently using the second unit, as when I updated the firmware in the first unit, it failed to work at all.
I have a 10Gb TP-Link PCie network adapter in my computer, connected to the 10Gb combo port, and the ONT connected to the other 10Gb port (at the recommendation of Wow! supervisor technician). I should be getting about 3Gb up and down with this setup. If I connect to the Wow! speed test, I get close to that (about 2500 down and 2700 up).
However, when I use any other speedtest (and I've tried dozens), I get varying speeds, but the upload speed is between 500Mb and 700Mb, with the download speed well over 2Gb, and sometimes close to 3Gb. This is consistent with local servers and no software VPN, or with Malwarebytes VPN enabled to Atlanta (I am in the Orlando, Florida area).
I have spoken to upper level support technicians at Wow! and they say everything looks good from their end.
If I connect the computer to the 2.5 Gb connection, I get various speeds, but they are more consistent, just under 2.5Gb.
What is going on here, and how can I fix it so I get something between 2 and 3Gb on uploads and downloads with a 10Gb connection?
Thank you.
