Issue - Xbox Series X - Network Slowdown


Recommended Posts

Edit: Escalated with our ISP directly.  🙂 I'll share a brief summary if / when it gets resolved. 


Edit 2: ISP seems to have resolved it. 

Over the past few days Ive tried various tips recommended by Microsoft including but not limited to: Port Forwarding, DMZ mode, static IP, various resets etc.


However, approximately 5 days after contacting the ISP, download speeds seem to have been resolved.


No visibility or response from the ISP but going from 30Mbps to 800-900Mbps is well… night and day.


What had originally happened: Download speeds were throttled to 20-30Mbps and Xbox whilst connected to the network would crash the modem and throttle the network for all devices. Modem would always crash and then return to normal (excluding the Xbox).


Resolved? TBD but working as intended now.

Not sure you read through that one yet.


Yes 🙂 I linked it at the bottom of the OP. I will try to contact the ISP today. There sees to be conflicting info where the OP there still has an issue (to my knowledge) whilst another user successfully resolved it by replacing their modem / router (HH 3000). 


Update: Contacted ISP, they will send a new modem. I’ll follow up if issue still persists.
