Hello,
Wonder if someone can help with a frustrating problem. For longer than I can remember, I have been using a Superhub 2 in modem mode, together with an Asus RT-AC66U router.
The reason why I set it up this way was because I found a particular online game would frequently disconnect and give lag spikes. I found that by putting the Superhub 2 in modem mode and using a separate router, the disconnects and lag spikes went away. I happily used the system in this configuration for years.
I recently upgraded my package to 1 Gig and was sent a Superhub 4 router. I was optimistic that whatever problems caused the lags and disconnects with the Superhub 2 would now have been fixed. My optimism was misplaced. As soon as I started using a Virgin router again, the lags and disconnects started up again!
No problem, I thought, I'll just put the Superhub 4 in modem mode, and use my own router, just as I had been doing without issue for several years. That was the start of an almost entirely wasted day. It seems the Superhub 4 simply does not work properly in modem-only mode.
I get the following error message within my Asus router's configuration page. "Unable to connect to the Internet". Please contact your ISP to find out the root cause of the DHCP failure.
I googled and found many people seem to be having the same problem with the Superhub 4 in modem mode. It seems some people tried various things like swapping ethernet cables, trying different ethernet ports, rebooting the Superhub, leaving it for 5 minutes, then turning on the router, leaving it for another 5 minutes. I tried all of that, and more, for several hours. I just get that DHCP failure error and no internet connection.
So I have reverted back to the Superhub in router mode, using the Asus device for wifi. (I have tried two separate routers, one brand new, and get almost identical error messages: ISP DHCP failure).
This is absolutely not how I wanted my service to work. I want my own router to do all the routing, and the Superhub 4 to be a modem and nothing more.
Any ideas? Note that the basic trouble shooting tips like trying a new ethernet cable, trying a different ethernet socket, rebooting all devices in a different order etc etc are unlikely to work. (Tried them all, no joy).
Many thanks in advance

Turn off the HUB 4 and the ASUS.
Ensure the ethernet cable is plugged into the WAN port on the ASUS.
Turn on the HUB 4 and wait a few minutes for the right light to settle.
THEN turn on the ASUS.

Step by step instructions:
How to put a VM hub into modem mode:
1) Access your hub on 192.168.0.1, sign on and put it into modem mode. On the Hub3 the bottom LED will change to magenta. Best done from a wired connection.
2) Turn off the hub and disconnect any Ethernet cables
3) Fully initialise your own router and make sure the WAN port is set to DHCP
4) Connect your router to the VM hub with an Ethernet cable, Cat5e or Cat6, any higher specification is a waste of money
5) Turn on the VM hub.
6) You should now be able to access the internet and the hub will now be on 192.168.100.1

Could you log into the ASUS, usually 192.168.50.1, and check the WAN status within the main 'Network Map' tab for errors.

You don't need internet to connect to the Asus.

That's fine, you can still connect to the Asus over WiFi.
Should look similar to this demo site:
