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.
