HUB in MODEM Mode
My 7+ year old Hub3 blew up last weekend and I got a replacement on Tuesday.
It is now a HUB5 but I also have a wireless router, so after a quick visit by the tech, I said I could sort out modem mode by myself. But then I had lots and lots of issues.
I'm pasting the guide I followed here to help others and maybe future me as it's fine if everything is working but if the HUB does a full reset back into Router mode, you may start seeing your router showing:
"Your ISP's DHCP does not function properly." message - which means you have no internet connectivity.
So the way to get the extremely temperamental VM HUB to work (this was the same with my HUB3 as it is with the HUB5) is do the following.
Full power down of HUB, Router, PC
Plug Ethernet from computer into MODEM
REBOOT MODEM and Reboot COMPUTER
Ensure Internet can be found and IP 192.168.0.1 Can interface with MODEM
Set MODEM from ROUTER mode to MODEM mode
Once the page has lost connectivity, disconnect ethernet cable from Modem and Power off all devices.
Plug ethernet cable from Computer into Router.
Plug Ethernet cable from Router WAN to PORT1 on the VM HUB
There should only be one ethernet cable from Router to Modem (PORT1)
REBOOT MODEM, Reboot Router and Reboot COMPUTER
Ensure Internet can be found and 192.168.100.1 Can interface with MODEM
You should also be able to locate your router depending on address (mine is 192.168.0.1)
These last steps can take a few minutes for the VM Modem to initialise and link properly with your router.
Whilst in startup mode I saw lots of messages like:
"The network cable is unplugged" and "Disconnected" before the final "Connected" message
TL/DR...
POWER OFF, POWER ON all devices
Order Critical: ROUTER OFF / MODEM OFF then ROUTER ON / MODEM ON
