Welcome to the community 🙂 I'm sorry to see the upload speeds have dropped on your connection lately.
I can see some issues on the upstream channels around the time you posted. It does look like there were a fair few errors on upstream data. Things have settled down since the weekend. I've tested the hub and network again today and everything looks fine at the moment. Will you keep an eye on things please, and let me know if the problems persist?

Currently there are no T3 timeouts showing on the Upstream (however only been up for a few hours). Prior to the Hub4 webUI being inaccessible, I do recall that since the reboot on 01/10 after three days there were 29 T3 timeouts on the Upstream.
Are VM working on a new firmware to address the loss of Hub 4 webUI access (which requires a reboot to resolve)?
