@unidenjunky , yes, that should work. Just to note, WPS is no longer secure and should not be left enabled in a modem or router. If you've already paired the device, log into the router and disable the WPS for both 2.4 and 5 Ghz networks. The paired device should keep working (?). If not, log into the remote device and enter / reenter the network name and passphrase. I'd be surprised if you had to enter the network name, but, one can't assume that the firmware design is completely logical.
"Does anyone know if it's possible to use MoCA while the modem is in bridge mode?". Yes, and no. Yes you can use your own MoCA equipment (minimum 2 adapters), and no, you can't use the modem's MoCA output when the modem is in Bridge mode as that output is shut down and can't be accessed thru the user interface.
There is a good reason why you don't want to use the modem's MoCA output anyway. From previous discussions, Rogers has been locking modems into the D-High band only, reserving the D-low band for the Nextbox Home PVR MoCA system. You will get better performance from a pair of MoCA 2.0 adapters where you can use the entire D band.
The MoCA frequency bands can be seen on page 9 of the following MoCA 2.0 / 2.5 Specification:
There are a couple of choices in terms of MoCA adapters:
There is a newer adapter out now that supports MoCA 2.5, running up to 2.5 Gb/s.
note that you will also need a MoCA 2.0 qualified splitter to replace your current splitter and a MoCA Point of Entry Filter connected to your incoming cable to prevent MoCA data from leaking from your network out to the external Rogers network, and leaking in from the Rogers network.
Here's a couple of links to MoCA threads that might be worth reading thru
@TechnicallyReal that Cat-5 cable might be the telephone cable that runs from the Bell box, down to the structured wiring cabinet where your telephone cabling for the house will terminate. Unless your house is very old, you should have a 66 block where all of the telephone cabling is connected to. The left side should have connected to the internal end of that Cat-5 cable, which ran downstairs from the Bell box, but now that its cut you probably have three pieces, one piece connected to the left side of that block, the long center piece, and another cut piece that runs into the Bell box. The right side of the 66 block should be connected to the house telephone cabling. Here's an image of the top of a 66 block, left side - external cable, right side - house telephone cables.
Which comes from the following page:
Edit: If you have one of those 66 blocks, check for the other cut end of that cable, still connected to the 66 block and possibly connected to a Rogers Home Modem if you happen to have one. Its likely that a Rogers tech might have cut that cable, which is unfortunate if you ever decide to return to Bell and actually have to use that cable.
Fwiw, depending on the path of that cable you might be able to use it to pull other cables thru, point to point. Just keep in mind, that you might want to actually leave a cable run in place, from the Bell box location to the 66 block. If you can, in effect use that cable as a pull string, consider running Cat-6 cable for your purposes, and leave a Cat-5 in place running to the Bell box (for future consideration. unlikely, but, hey, you never know).
