ORBI

Hi there gang!

I have a quick question

I think I have double nat as I have an orbi installed (router mode) behind a comcast gateway that is broadcasting a wifi signal too and is not in bridge mode.

I have different computers on same orbi network with drastically different speed test numbers 20mps on one desktop and 220mbs on another.

 

Anyway, I want to change my comcast to bridge mode and put my orbi in ap mode so that orbi is the only thiing broadcasting wifi.  The problem is that it's already set up as above and I have over 26 devices hooked to the orbi wirelessly (echo dots, nest cams, thermostats, hue bulbs and sonos, etc.) and I'm afraid I'll lose all connections and have to set everything up again.

 

What steps in order of detail do you think I should do?  enable ap mode on orbi and then log into comcast and enable bridge mode?  Will everything come back online to the orbi after doing this since they were originally hooked to the orbi in router mode?  Or do you think I will have to start from scratch?

 

I appreciate your help so much.

 

Thank you!

Marc

  • If you are switching the Comcast gateway to bridge mode, then you would want to leave the Orbi in router mode. At least one of the devices needs to be a router. Once the Comcast gatway is in bridge mode, it will stop NAT'ing, but you want to ensure that the Orbi still does NAT.

        I see, so putting the orbi into AP mode doesn't allow it to be a router?  (assuming the comcast gateway is in bridge mode)

        Why would you even want ap mode?

  • I basically just went thru and completed as of today a similiary exercise.  I replaced one router and several access points with the Orbi.  I have as of this posting 47 devices connected out of a possible 70.

     

    You have probably completed this effort, but 1). I had exported my config from my previous router to get a copy of reserved IPs and Ports forwarded.  2). Just go for it and be prepared to make a couple round robins on the various devices to reconnect them.  3). I renamed my SSID so that made it a requirement I visit each device, which I wanted to anyway.  If you don't changed SSIDs, you might get lucky and everything reconnets.
