Hey,
I was offered a rogers package and I wont get into the sale technique used, but anyway I received the CGM4331COM modem on a Ignite 1500mbps package. I have a rather complicated home network with about 6 computers and a file server that are all wired to a TP-Link AX6600 router and a 2.5GB switch. My old cable modem was just a dumb bridge. With this new modem/router combo I can't surpass 850mbps over wifi or wired, apparently the 4th port is 2.5gbps and I wire it with a new cat6 into the 2.5gb port on my router and I can only hit about 700mbps wired or wifi, if I wire directly to the modem not using bridge mode I get slightly higher speeds, but I can never get above 850mbps,
I can transfer files between systems at full speeds and the modem and router both show they are negotiating at 2500mbps but I can't achieve internet speeds above 850mbps and speeds always drop in bridge mode.
Any ideas? I can see others seem to have similar issues with the 2.5g port being slower than the 1g ports

It's a long story, I don't have Rogers fibre available to me at all. A salesperson came into my building and lied to a bunch of us knowing that a different fibre provider was going to be selling to our building, so they tried to undercut our current package and weasel in. I had to file a CRTC complaint about it
@-G- I was never able to break 1000mbps over wired, not with any of my 3 2500gbps capable devices
EDIT: Just hit 1700mbps over the 2.5g via my unraid server, went back to bridge mode and its back down to 850, lol

Ok, if you're in an apartment, there's a good chance that you're not going to be able to run anything over 1 Gb/s. It all depends on the cabling in the building and the number of splitters between the Multiple Dwelling Unit (MDU) which services large apartment buildings, and your modem. If you're in an old apartment building, there's a chance that you might have RG-59 cabling which is designed for analogue tv transmission. That would have to be determined. The prefered cabling is RG-6, which has less signal loss compared to RG-59.
In terms of a splitters, somewhere around the front of the apartment you should see a small communications closet which houses the apartment telephone and tv/internet cabling. You might find a cable splitter still installed which connects to all of the cable ports in the apartment. That splitter should have been removed and replaced with an F-81 connector, where the inbound cable from the MDU connects to the singular cable that runs to the modem The F-81 connector looks like this:
https://www.homedepot.ca/product/ideal-3ghz-f-splice-adapter-10-pack-/1000751479
If you self installed the modem, there would have been an F-81 connector in the modem packaging. If the modem was installed by a tech, he, or she, should have removed any splitters and installed the F-81 connector.
If you posted the modem signal levels and codeword tables, we might be able to make some sense out of this situation. Those tables will copy and paste into a post, just like copying the tables from one document to another.
Fwiw, don't give up yet. Have a look to see if there is still a splitter installed, as that will drop the signal levels reaching the modem and push up the upstream levels heading back to the MDU. So, no matter which provider you use, you will end up with the same problem. At least in terms of signal levels. The larger the splitter, the larger the downstream signal drop. The signal drop for each port is marked beside each port.

Thanks again, not sure if you saw the edit to my last post but I hit about 1750 using the 2.5g port going to my 2.5g switch when in gateway mode, then when I switched back to bridge it went down to 850

That's weird. I don't know why switching to Bridge Mode would cut your speed in half. The Ignite gateways can be really twitchy sometimes... and while I have seen them perform well, I have also seen numerous weird interoperability issues.
Rogers does support bridge mode on the Ignite Gateways... and if you can confirm a speed drop simply from enabling bridge mode, tech support should be able to create a ticket and escalate it to their internal support teams for investigation. Perhaps the @CommunityHelps team can assist with this, and i would encourage you to send them a private message.

If you can get that speed when connected without bridge mode, then it's your responsibility to troubleshoot your system for why the speed is reduced in any other mode.
I'm subscribed to much less speed, but I get 1.4 Gbps to my Mac Mini M2 with 10 Gbps Ethernet adaptor. Rogers typically supply what you pay for, or more as discussed in numerous threads on this forum. If you are not getting what you pay for, it's almost always as a result of an issue with customer equipment/settings.
Here's hoping the other experts can assist you with your issue, but it's probably a setting or equipment issue on your end.

The rogers tech said they absolutely do not support bridge mode "because it's connected to a 3rd party device" I asked is my computer that it's directly wired into a 3rd party device, and they said yes 😛 (dude was insanely rude in many other ways as, kept disregarding my questions and saying "we don't support that" quickly followed by "all set then?"

Nothing changes on my end, only setting changed is bridged or gateway mode on the modem, I have confirmed this
I'm not alone in this https://www.google.com/search?q=xb7+bridge+mode+slow&oq=xb7+bridge+mode+slow&aqs=chrome.0.69i59j69i6...

I don't necessarily agree with that. There should be no difference in the data rates between Gateway and Bridge mode. There should be no difference in the ethernet protocol out of the modem, for either mode. So, what you see in Gateway mode should be the same as what you see in Bridge mode.
I agree with @-G-. Don't give up the ship just yet. Either swap the modem, or let the moderators raise a ticket to see if this can be solved. Swapping the modem might be the easiest path out of this.

If you follow those threads (and many others) to their conclusion, you will find that it was always a customer hardware or setting issue. Here's hoping someone can find out why you're having this issue.
If you're getting the speed you pay for when directly connected, then you should be able to understand why Rogers will not provide additional support when you're not connected in Gateway mode. Again, I hope that the experts here can help you find out why. I am not an expert on various routers, etc.

maybe, but I don't really want to stick with rogers, I just like trouble shooting tech stuff, also it seems to be a super common issue and I don't think its going to work after all I have tried

Where? Every one I see they either give up, up buy some stupid expensive 10gbps gear, I'm just rocking cheap stuff I pieced together. Wifi gets faster just because my router is ax6600 but wired locks to around 850 every time in bridge mode, there are not a lot of settings once it's in that mode

Seems like Rogers telephone support has been going steadily downhill over the years, with support techs being untrained, unwilling or unable to provide support for many features and functions that more advanced users require.
Here's a thread from a few years ago: https://communityforums.rogers.com/t5/Internet/Strange-recurring-issue-with-Rogers-Technicolor-CGM41...
When multiple users with Gigabit Internet plans were reporting slowdowns in Bridge Mode, and I noticed the common thread that they were also all using Ubiquiti EdgeRouters, Product Managers stepped in and were able to confirm the bug in their lab, and they then escalated the issue to Comcast for resolution.

@otakunorth One more thing: When running an Ignite Gateway in Bridge Mode, make sure that you have one (and ONLY one) device connected to the gateway's Ethernet ports -- your router.
05-30-2023 11:07 PM
Thanks yeah, I just have my router plugged into port 4 when in bridged
