Disable auto change IP address
I've seen similar posts about a way to disable the auto change IP address before. They've been brushed off. The 'answers' and 'solutions' are wrong. There is an issue with the product. Every month wh...

I continue to be amazed. garrettg64's Ubee DDW36C User Guide has that section 6.7 that describes "Passthrough", although I am confused by the description. It looks like up to 32 MAC addresses get "added" to a table which "Displays the MAC addresses to be blocked." So, are these MAC addresses "passed through", or are they "blocked"? And, "Input Host" refers to??? (the modem? the Orbi? Spectrum?)
My Ubee DVW36CB (voice, with a battery slot which Time Warner left empty) User Guide does not have section 6.7. Nada. So, that means that my Ubee cannot be set to Bridge Mode?
Ok, here's how I interpret that: There's a table which can contain up to 32 MAC addresses. Any addresses added to that table are blocked from being intercepted and managed by the Ubee. The are, instead, passed through the Ubee to the ISP, so the ISP can manage them (which generally just means that a device configured to use DHCP will send out an ARP broadcast requesting to be assigned an IP address by the DHCP server, and instead of the Ubee responding, the Ubee is blocked from responding, and being told to pass the ARP message through to the ISP, for the ISP to respond to instead), as though they (your network device and the ISP) were directly connected without the Ubee as an intermediary. And I think "the input host’s MAC addres" also has awkward wording, but means "the MAC address of the host which you, the user, have input."
Basically, the descriptions are garbage, but it makes perfect sense if you look directly at the (image of) the config page.
Pass Through MAC addresses [gives example of what a MAC looks like]
[field to input your specified host's MAC] [button to add the MAC, which has been input, to the table]
[table of added MACs, displayed in list form] Addresses entered [count of MACs entered into the table]/32
[remove single selected MAC from the table button] [clear entire table button]

Maybe it's just as well that MY Ubee modem doesn't have this feature. If this feature really operates like this, then it certainly is NOT what I think of as bridge mode. The ISP has no idea what router the user is going to connect to the modem, and the user is able to change home routers at will. In bridge mode, the user cannot get into the Ubee to input a MAC address for the ISP, and I have never heard anyone on this forum talk about putting MAC addresses into their modem. Even if it was intended to run the other direction and the ISP was supposed to put in the MAC addresses of up to 32 hosts that might communicate with the modem, that would unmanagable in the long run. They can't go around updating tables in every modem whenever they add or swap out equipment.
I think we would all agree that when we put our Orbi in "router mode", it should be impossible for anything except a logged in administrator to change the mode to something else or create a VLAN Bridge. If we have set the LAN IP to 10.99.99.1, then the Orbi should not change it to anything else unless it saw 10.99.99.1 on the WAN side. If garrettg64's router suddenly changes its LAN address to a public address, it has gone wack-o. He did a reset to factory a couple of days ago, and will learn in just under four weeks if the problem still exists.
It would be interesting if some community member has a Ubee DDW32C in bridge modem on Spectrum and has "no problems."
One way to tell if the ISP modem IS bridged, the IP address should be a public IP address ON the Orbi's WAN side. If your not seeing a ##.##.###.### kind of address on it's WAN port, and you see anything else like a 192, 172 or a 10 IP adderss, the ISP modem is not bridged.
