Xbox One X Outrageously Slow Wifi.

Mutilat1on · Nov 7, 2021

I have looked far and wide for an answer to this issue and Microsoft Support no longer answers questions for the One X.

I have both an Xbox Series X and an Xbox One X. My issue is that the Xbox One X's Download speed and Upload speed are absolutely horrid. 25.97 Mbps Down/36.53 Mbps Up. It is wirelessly connected as I am unable to hardwire it due to location issues. I know and understand that wifi is not the way to go, but it is my wife's and she doesn't play any lag-issue games. Prior to about 3 months ago, I was getting well over 100Mbps Down/Up wirelessly with it. It now will not go close to even 30 Mbps.

My setup:

ARRIS BGW210-700 gateway (1Gbps Fiber):

WiFi off

IP Passthrough enabled

Allocation Mode: Passthrough

Passthrough Mode: DHCPS-fixed

All Firewall settings are off.

Connected to a ROG GT-AX11000 Router:

Firewall: Standard

Game Boost: Enabled

QoS: Gaming

Both the Series X and One X are set to gaming.

I have turned QoS off entirely and speeds dropped to 17.72 Mbps Down/23.75 Mbps Up

Gear Accelerator: On for Both the Series X & the One X

Open NAT: Profiles created for Both the Series X & One X

Full Cone NAT

Smart Connect: Enabled

Wireless Mode: Auto (No other Options)

802.11ax/Wifi 6 Mode: Enable

WiFi Agile Multiband: Enabled

Channel Bandwidth: I have tried every configuration from 20MHz to 160MHz and even 20/40/60/80/160MHz

Control Channel: I use InSSIDer and checked all channels, there is no overlap, in fact, our neighbors are so far away their wifi barely appears.

Multi-User MIMO: Enabled

OFDMA/802.11ax MU-MIMO: DL/UL OFDMA + MU-MIMO

IPv4 DNS: 1.1.1.1; 1.0.0.1

IPv6 DNS: 2606:4700:4700::1111; 2606:4700:4700::1001

DMZ: I even put it in a DMZ and there was no change.

I've even verified that it is connecting to the 5G band.

Short of Factory Resetting the Router and starting from scratch, I have no idea where I have gone wrong.

Xbox One X:

Packet Loss: 0%

MTU: 1480

Latency: 32 ms

Wireless Strength: 100%
