disconnection from remote systems several times a day

[g142]

Hi, I'm getting disconnected from remote systems several times each day, using a wired connection into hub 3.0

network speed can vary wildly, should be 200, but its often below 10 for hours though speed seems to be a bit better recently.

Is there anything in the following logs that would indicate a problem cause?

I have an old Netgear router that I could use with the Hub3 in modem mode. Looking at the number of posts on here with people reporting remote access problems I wonder if I might as well go straight to that? Does anyone ever get these type of problems resolved?

Looks like a noise ingress problem! - VM would need to investigate.

May I ask when the last time you rebooted the hub was? (The errors are cumulative and a hub reboot clears them)

Hi, I figured that I should go modem mode with a standalone router anyway, as so many seem to have problems with work VPNs.

new monitor setup with hub3 in modem mode

https://www.thinkbroadband.com/broadband/monitoring/quality/share/39701df539a18d89e87fc5659e36376dce... 

Got a TPLink AX1500 , seems like it should be all automatic to connect up, but it failed to find the internet.

So I found what my current settings were for internet connection in modem mode , IP, Subnet, Gateway,DHCP,DNS etc. and set it up manually.

That worked OK and all reconnected again ok after powering everything off for 5 mins, but now my question is: will these static settings remain correct or will my address be changed dynamically at some point and I should be looking to resolve the dynamic setup problem with the TPLink router?

Looks like VM are not doing DAI for your area?

I guess you got the IP settings with the hub in router mode or modem mode with a PC yet the MAC of the TPLink allowed it for them IP settings which really should not happen.

I suggest turning off the hub for 2min change your router to DHCP then turn hub back on.

[g142]

ok, I've set it back to automatic and its worked this time.

The host IP changed again so I've made a new BQM graph

Ready to test work vpn connections from tomorrow.

The system has been much more stable with the hub in modem mode and my own router in place.

I had only one disconnect on Monday, and another today but I think there was a general outage in the area today that caused that.
