I just upgraded my Internet service today and got the new CODA-4582U modem. Tried to set it up to bridge mode and am experiencing the exact same problem that you described - third party hardware will not work... so frustrating.
@amarcel, what router do you have?. Sometimes, when changing modems, you have to run a complete factory reset on the router in order to get the router to work with the new modem. We've seen that before. Yes, its a pain to have to reenter the parameters, but, hopefully that will result in a working combination. Usually from what we've seen, moving from one Hitron modem to another isn't an issue, although with the 4582, there have been issues in the past with DLink routers.
Edit: Ok, I see that you're using a Linksys router. I don't recall Linksys routers proving to be a challenge when connecting to a Hitron modem. I would flip the modem back into Bridge mode and then, with the router powered up and running, run a factory reset on the router.
You can log back into the modem when its running in bridge mode by using 192.168.100.1 as the login address. After logging in, navigate back to BASIC .... GATEWAY FUNCTION, and reenable the Residential Gateway Function. Save the change and the modem will reboot back into Gateway mode with its previous settings intact. Running a Factory reset to accomplish the change from Bridge mode to Gateway mode will result in the modem parameters being set to their default values.
Until now my wifi with rogers modem is up and down.
Sometimes 2.4 G download rate is better than 5G.
Is it better for me to set Rogers modem to bridge mode and set up 3rd party router?
"Is it better for me to set Rogers modem to bridge mode and set up 3rd party router?"
Yes. But, the same can be said for the vast majority of ISP Gateway modems worldwide. My advice for anyone who relies on wifi is to buy a reasonable router with external antenna. You don't have to go uber expensive, but at the same time, don't go cheap either. The one exception to the external antenna recommendation is Ubiquiti UniFi access points. UniFi users seem to be pretty pleased with those access points from what I've seen.
If you're having problems with wifi, have a read thru the following post, specifically the section on wifi settings and checking your wifi environment.
Hi there - Thanks for your note, but I am trying to accomplish the opposite of what you described. The new CODA-4582 modem that I got today came with the "home gateway" setting enabled by default, but I actually want to run it on the "bridge mode". When going to 192.168.100.1 and switching the modem setting to "bridge mode", the internet immediately stops working on my Linksys Velop mesh router. I am able to log on the modem and switch it back to "home gateway" so that my router will resume working, but that defeats the purpose, since my goal is to have the modem on "bridge mode" AND get the router to work.
