I put my Hub 3.0 in Modem Mode, but there seems to be a conflict between the 192.168.100.1 address it uses for the admin web page access and the VPN I have to use to access work (I'm a 100% at home worker, even without the COVID thing). If I try to access 192.168.100.1 with the VPN on it times out, and if I turn the VPN on it doesn't. The company must be using 192.168.100.x on it's internal network and routing all of that traffic into the VPN. I can access other machines on my internal network that runs on 192.168.4.x just fine. Apart from begging the IT gods at the company to put the other machines on a 10.x.y.z range does anyone have any ideas?
It likely will as you are connected to your work's vpn - Mine is the same - only way to access router settings and modem is to disconnect from the VPN.
I was hoping there was a workaround, but I guess it's on/off VPN in future for me then. I've been accessing the router quite a lot recently as it seems to be rebooting itself once a day around 11:00am. I did a pinhole reset yesterday at the request of support to try to solve it but I'm not holding my breath.
Can you post your Hub status and logs?
Someone should be spot if there is a problem
Navigate to http://192.168.0.1 (or http://192.168.100.1 - if in modem mode)
Don't log in!
Click on 'router status'
Copy/paste the data from each of the tabs. The forum software will remove the MAC addresses for you (you may need to click the 'post' button again).
Also, set up a 'Broadband Quality Monitor'. This will monitor the state of your connection and record any network dropouts etc - You can do this at ThinkBroadband (https://www.thinkbroadband.com/broadband/monitoring/quality)

Your upstream power is too low! - VM will need to book a tech visit to rectify!
Hang tight and forum staff should pick this up presently!
Basically, what's happening is: Because of the low power, your hub cannot hold a good connection to the cabinet and so tries to renegotiate with it to get a better signal - this looks like a hub reboot and takes about 5 minutes - If the renegotiated power is still too low - it tries it all again. Leading to a very unstable connection.
Interesting, thanks. We had a tech visit a couple of weeks ago for this same problem, and he redid the cable connection at the house due to a misalignment (at least that's what I think he said) and even went to the cabinet on the street and checked and changed stuff there. It was OK for a day or two (I think) but since then it's been 10am to 11am pretty much every day that it disconnects, all the lights go out and it starts flashing, then it comes back up 5 minutes later with zero uptime in the status screen.
Hopefully the next tech will be able to get to the bottom of it!
