I always used my Hub 3 in modem mode with an Asus RT-AC87U router. Yesterday this suddenly failed. I can still connect to my router, and all networking on that side works fine. I was unable to login to the Hub 3 (trying 192.168.100.1 and 192.168.0.1).
After calling Virgin support, who talked me through a full reset (holding the reset button for 60 seconds), the Hub reset to Wifi mode and connected to the internet. When I then set it back to modem mode, assuming it was all working again, I again lost connection and had no way of logging back into the Hub.
It seems that the Ethernet ports are not allowing any connection, so the moment I switch to modem mode, I lose the Hub. Also, while not in modem mode, the router does not connect to the Hub via Ethernet.
when using modem mode, if you do a direct connect to the hub using e.g. PC/laptop do you get a valid external IP address rather than the 192.X, also have you reset the Asus to default

Strangely, I just had some electrical work done and the power was turned off for a short while. When it was turned back on, the Asus router connected to the Hub3, receiving an IP address. This didn't happen before, even after I turned everything off and on again. So then I turned it back into modem mode, connected the Asus router again and it's all working as normal again.
Slightly unsatisfying that I don't know why it didn't work for the better part of a day, but at least it's working again (for now)!
I ask this because the first time you use modem mode, and possibly if the IP address changes during a power cut, you must turn your equipment on in a set sequence.
Turn everything off.
Turn on hub and wait for it to initialise in Router Mode.
Connect a machine to the hub (do not have your own router connected to the network) and put it into modem mode
Check bottom LED shows modem mode
Turn of hub
connect your own router, power on until fully initialised
Now power on the VM hub
The sequence is like this because the MAC address of your router needs to be saved in the VM CMTS. Normally a power off/on does not require this sequence, but if you have changed IP address by being moved to a different CMTS I can see it being needed.
There are 10 types of people: those who understand binary and those who don't and F people out of 10 who do not understand hexadecimal
making sure everything is switched on in the correct order makes for a temporary fix, but the Hub keeps crashing and becoming unresponsive, requiring manual reboot (unplugging and plugging back in). (IP address has remained unchanged throughout all of this, by the way)
Here's a link to a BQM showing what's happening, any ideas what might be causing this?
