Orbi RBK12 - question about setting up bridge mode on combined router/modem
Hi, I'm trying to set up bridge mode on my combined router/modem to use with my Orbi RBK12. My ISP isn't able (i.e. won't) help me to set up bridge mode, so in the end I successfully set up the DMZ s...

Hi, thanks for your reply. It’s a Technicolor DWA0120.

Thankl you for confirming the modem model. :smileywink:
You can do a search online to see if that model pulls up any kind of bridging information. Might ask the mfr about this as well.
- SethOxNov 09, 2020GuideHi, after Googling I found some instructions from a different ISP (Zen) for putting the Technicolor TG589vac router into bridge mode (apparently my router DWA0120 is a direct replacement for the TG589vac, so I guess these instruction also apply for mine?) I’ve attached a screenshot showing the relevant bits of the instructions. You can clearly see the same warning disabling the auto sensing of the WAN interface. If they say to go ahead despite this warning, does that mean it’s ok?
My question is generally whether or not disabling auto sensing of my WAN interface is going to mess anything up? I have no idea of what this means or what the implications are, and I’m just trying to check if I can safely do this- FURRYe38Nov 09, 2020Guru - Experienced User
I don't know. The UI could be the same or different between the two models.
It is something to try. If it doesn't work, you can revert the change or reset the modem and setup from scratch...

An installation manual for the Technicolor DWA0120 is on the web:
https://www.manualslib.com/manual/1565576/Technicolor-Dwa0120.html?page=8#manual
Notice how there are two ways to connect the DWA0120 to ISP devices (DSL and ethernet). As no switches or configuration is required by the user, my assumption is that the DWA0120 "automatically senses" what the DWA0120 is plugged into except in bridge mode, where it goes by the setting on the web page. When you log into the device (192.168.1.1), the setting should be correct (already "sensed"). And, of course, it should be obvious which ISP device is being used (DSL or VDSL).
The "good news" (on the last page) is that if something goes horribly wrong when you change it to bridge mode, sticking a paperclip into that tiny "reset" hole will but it back to the Factory default, where it will "sense" again.
In other words, it appears to me that you have nothing to lose. GO FOR IT!

Hi, thanks a lot for your reply. I tried putting the modem/router into bridge mode and the good news is that nothing catastrophic happened. However, the Orbi router had no internet so it didn't work as intended. Here's what I can see:
In bridge mode, the Gateway admin page says that only ports 1 to 3 will be bridged, and port 4 can be used to access the Gateway admin page. So I plugged the ethernet cable from the Orbi router into port 1 of the bridge-mode modem. However, when I went onto the Orbi app, the router had a magenta light and it said "Internet: Offline". In the Gateway admin page when I checked the port status it said that Port 1 was connected, but then when I looked at the list of connected Devices it couldn't see the Orbi router (which was connected to Port 1).
Is there anything obvious I'm missing here? From your comments it sounds like I might have to tell the modem where to find the Orbi router, is this right? Or do I need to do the Orbi setup again?
