XT8 unexpected upload traffic from the router

[Da22a1]

After noticing poor network reliability I've found that my router appears to be uploading massive amounts of data at about 50MB/s for periods of about 1min, stops for just under 1min, then starts uploading again.  When this happens there is no evidence of any device on the wireless or wired network uploading any data, which suggests it's the router doing this.  I have 3 XT8 devices in the mesh, but when this upload happens, it continues even if I switch off the other 2 nodes, so it's definitely the router doing it not one of the nodes.

Rebooting cures it for a while, but sometime later it starts again.

All devices are on the same FW and upto date with version 3.0.0.4.388_24668-gb5d7304.

It's like the router is launching a DoS attack on itself!

Any help or clues as to what might be wrong would be helpful. I haven't yet factory reset the device, that's my last resort.

I have the exact same problem.

My router just kept rebooting or completely dropping the 5ghz networks (including wireless backhaul) on that firmware.  I had to downgrade to 3.0.0.4.388_24621-g9054e31 and I've been stable for about 5 days now.

Thanks.  Will give it a try.

Hi @Da22a1 @tacarey27 @MarkWood21 ,

Thank you for providing detailed information about the excessive data upload issue with your XT8 router. 

Based on your description, the router is frequently uploading large amounts of data without an apparent reason, affecting network performance, and restarting the router only provides a temporary solution. 

You have also ruled out the possibility of other devices causing the issue, confirming that the problem lies with the router itself.

Here are some potential solutions you can try:

• Check router settings:

1. Remote management: Ensure that remote management is not enabled on the router and that there are no unauthorized devices connected.
2. DDNS service: If you have enabled DDNS service, check if the settings are correct and ensure that no malware is utilizing this service.

• Reset the router:

1. Restore factory settings: If the above methods do not solve the problem, you can try restoring the router to its factory settings. This will delete all custom settings but can rule out software issues.
2. Reconfigure: After restoring factory settings, reconfigure the router and carefully review each setting.
