Hub5 no internet in modem mode

[Trev_Allen]

I have been trying for two days to change my Hub5 to modem mode. I am connecting to an asus rt-ac68n router running DD-WRTV2 in automatic DCHP mode.

I have followed this procedure.

1) login using 192.168.0.1 and select modem mode with only port 4 connected to the router.

2) When the hub5 status light changed to steady green and I can log in using 192.168.100.1 either directly from my laptop connecting to port 4 or via my wireless router connecting to port 4, I wait for the Home page status that wireless is off, internet is online, telephony is ready.

3) I then depower the Hub5, wait for a minute and with the asus router connected to port 4 (also tried with the laptop only) I power up again.

4) Eventually when home page status shows internet online, telephony ready I wait but no internet connection becomes available even after 50 minutes. On the Admin info page no WAN IP settings section is displayed.

Is there anything further to try?

When your laptop was connected could you navigate to google.com, or any site?

No, nothing. Ping test wouldn't work either. It behaves like this every attempt but works perfectly reverting to router mode

And the objective is to set up a wireguard home server for remote working

Could you try one of the other ports?

Just to confirm there is nothing connected to the other ports on the HUB?

So tried again with laptop on port 1. Working. Then rebooted with wireless router plugged into port 1. Not working. Tried laptop into port 4. Working. Rebooted with wireless router into port 4. Not working. Rebooted with wireless router in port 4 but no ethernet cables connected to wireless router this time. Working!!! Plugged ethernet cables back into wireles router and continues to work. FYI all devices connected to the wireless router have a different LAN IP address. Is this expected behaviour?

And Carl, thanks for your help

Each device will have a unique IP address, probably 192.168.50.x being an Asus router.

All my routers have DD-WRT loaded, so I've set them up to avoid conflict.

My further confusion comes regarding port forwarding in modem mode (which is still working 24 hours later 🤞) but the modem mode menu has no options for this. There was a mention in the community that the router needs to be in modem mode to use port forwarding but is this is a red herring? Just to recap, I want to run  wireguard vpn on the router I'm connecting to the Hub5. Do I really need modem mode for this or should router mode with port forwarding be ok?

[carl_pearce]

Port forwarding is actioned on the router, so in modem mode there is no port forwarding on the HUB, it's configured in the Asus settings.

Thanks.

And one last question for those of us who actually read the manual, is there anything published for the Hub5?
