Using CBR40 in bridge mode with RBR750
So I recently (today) acquired an RBR750 mesh wifi router (and three satellites) to improve coverage and performance in my home. I've been using the CBR40 as modem/router, but I have serious dead spots, and thought, rather than expand what's basically an obsolete system, and rather than spend extra money to buy a new router/modem combo, I would pick up the RBR750 and put the CBR40 into bridge mode, saving the $100 or so relative to the CBR750.
It doesn't work. If I hook up both routers, they seem to get online ok, but then they're both radiating in wifi and fighting against each other. But as soon as I switch the CBR40 to bridge mode, the whole system loses internet access (and the CBR40 becomes totally inaccessible, requiring a factory reset (which I've done several times now).
Spectrum is my ISP. They say the CBR40 is activated and ready to go on their end--even when I can't see it on mine. Any thoughts? Any tricks I'm missing here in getting this configured? Do I just need a different cable modem? Thanks!

After you put the CBR into bridge mode and after you hit apply, reboot or power OFF the RBR750 for 30 seconds then back on. Should have Internet here. Check the RBRs web page under basic tab to check the status of the internet connection after the RBR comes back online.
- Thanks. This did not work. Rbr750 shows 0.0.0.0 for gateway, dns, etc. It’s like the 750 can’t talk to the CBR40 at all when the modem is in bridge mode. I asked Spectrum if we could try registering the router with them but they insisted that wouldn’t work. I may just try it myself. Anyone here have any experience with this?
Ensure the WAN port of the CBR40 is being connected from the WAN port on the RBR750.
Swap LAN cables. CAT6 is recommended.
