Ok, just to prove or disprove the CGNM-3552 data rates, can you log into the modem by using 192.168.100.1 as the modem's login page address. Can you let us know:
1. What Software (firmware) version is load as indicated on the status page; and
2. let us know if at the present time you have two addresses shown in the WAN IP address in the upper right hand corner. There might be one IPV4 address followed by an IPV6 address. If not, the modem will require a factory reset so that it can negotiate with, or be assigned an IPV6 address by the Cable Modem Termination System (CMTS)
3. Navigate to the STATUS .... DOCSIS WAN page, copy the downstream and upstream tables and paste them into a post in this thread. The copy and paste process will paste in the text contents of the tables.
4. Navigate to the STATUS ...... DOCSIS EVENT page and have a look for one of the following sequences:
a. CMTS-MAC=00:17:10 which indicates that you are connected to a Casa Systems Cable Modem Termination System (CMTS), or;
b. any of the following which indicates that you are connected to a Cisco Systems CMTS.
1. CMTS-MAC=00:05:00
2. CMTS-MAC=00:12:43
3. CMTS-MAC=00:14:f1
4. CMTS-MAC=00:1f:ca
5. CMTS-MAC=e0:2f:6d Note: there may be other Cicso MAC addresses as well which are not on this list yet.
Please let me know if you have the CMTS-MAC=00:17:10 sequence in your DOCSIS EVENTS log as you will need to request the trial version 4.5.8.21 if you are connected to the Casa Systems CMTS, which that sequence indicates.
5. If you are in Gateway mode you should see STATUS, BASIC, WIRELESS, ADMIN, SECURITY across the top menu bar. If you only have STATUS, BASIC and ADMIN, you're in Bridge mode. If you're running your R7000 this is where you want to be, otherwise you have a double NAT situation going on.
To switch back and forth from Gateway to Bridge modes, navigate to BASIC ..... BASIC SETTINGS. Enabling the Residential Gateway Function will switch the modem into Gateway mode (its normal modem / router mode) from Bridge mode (modem only mode). Disabling the Residential Gateway Function while the modem is in Gateway mode will switch the modem into Bridge mode where you then require a follow-on router. In each case, when you enable or disable the function to switch modes, the modem will reboot into the desired mode. You could also run a Factory Reset to force a switch from Bridge mode to Gateway mode by using the ADMIN .... DEVICE RESET .... Factory Reset function. This will result in a total reset back to factory default settings and will reboot the modem back into Gateway mode.
6. What I would suggest to prove out the data rate capability is to reset the modem back into Gateway mode, disconnect the router for test purposes and connect a desktop or very capable laptop directly to the modem. You should see that the connected port LED at the back of the modem is amber, indicating that its connecting at 1 Gb/s. Green indicates a 10/100 Mb/s connected port. So, if you connect a device with known gigabit capability, and only see a Green Port LED, then you know that there is an issue with the connecting cable, possible bad connections at either end of the cable where it connects to the modem or device ports, or that the port on the connected device is not set to run at 1 Gb/s. Its possible to set desktop and laptop ports to run at slower speeds, so, sometimes it is necessary to drill down and check the advanced ethernet port settings and confirm that its set for 1 Gb/s or Auto. Some motherboard manufactures don't specify in the settings exactly what Auto means, so you would have to know that the port is capable of 1 Gb/s by digging into the specs.
So, the first step is to confirm that you do see speedtest result in the +900 Mb/s range. That will depend on the end test device, so, don't be surprised to see something in the 750 to 950 Mb/s range. To test that speed, you should use the speedtest.net Toronto Telus server, followed by the speedtest.net Beanfield server as second choice.
Once your at that point, the next step is to switch the modem into Bridge mode. Initiate that change and connect the R7000 while that is happening. Don't power up the R7000 just yet. When the modem has completed the change over, power up the R7000 and ensure the the connected port LED at the back of the modem is Amber, indicating a 1 Gb/s connection rate. Connect the same pc or laptop via ethernet to the R7000 and run a speedtest using the same server.
Just to note, the R7000 uses Broadcom's chipset, which uses Cut Through Forwarding, commonly referred to NAT acceleration. I don't know if you are familiar with that, but essentially its port forwarding at a chip level, bypassing the processor if and when possible. With the NAT enabled you should see rates in the high 800 to low 900 Mb/s. The data rate is speculation on my part. That CTF, or NAT Acceleration can be disabled by numerous functions that require the processor to do something with or to the data, such as traffic monitoring, QOS, and a few others. The last time that I looked at this in the R7000 user manual, there was no indication of any warning or function enable/disable. Maybe that has changed, but that's something that I don't have an answer for. You're going to have to look for that function if you're not familiar with it already and ensure that its enabled. Without it, you're probably never going to see the data rates that you're expecting.
Ok, hope that helps. Please let me know what you find for the above questions and let me know what your date rates test out to, with the modem in Gateway and Bridge modes.
Edit: Just to note, I don't know if DD-WRT will support high data rates as it may not enable the CTF / NAT Acceleration. As far as I am aware, you should be using the stock firmware or the Asus-WRT which has been compiled to run on the R7000.
There is an ongoing issue between the Casa Systems CMTS equipment which supports gigabit data rates and the CGN3ACSMRs / CGNM-3552s. This is resulting in the modem LAN ports dying. There is a trial firmware version available to resolve that as indicated in the following post:
With the trial version 4.5.8.21 on a CGNM-3552, I and others have seen a secondary 2.4 Ghz network transmitted that has no SSID. This hidden network can be seen by using a wifi monitoring application such as inSSIDER on a laptop. Take a read thru post #157 to 161 in the following thread. My personal opinion is, if the power levels are correct, then this is bad news for anyone relying on the 2.4 Ghz network and may be a partial explanation for users experiencing issues with Chromecast devices.
inSSIDer will monitor both 2.4 and 5 Ghz networks that can be detected by your laptop. The program link is for the last freebie version. A new version is out now that will handle 802.11ac networks, and which will work on a 802.11n laptop. The new version will read the broadcast management frames and display the 802.11ac networks that are running in the 5 Ghz band. It worth the $20 U.S. to buy, so that you can see all of the networks that are nearby.

Can you delete the Docsis Events log portion of your post as it has your MAC address in it. It does confirm that you're on a Casa System CMTS. With that in mind, can you have a look at the following thread and follow the links to request V4.5.8.21 for your modem.
I'm out of time for now, so I'll have to return to it later today 😞
@Spirit84 can you run an ethernet connected speedtest using the speedtest.net Toronto Telus server and let me know what the results are. If you let speedtest.net select the server, you can end up with a server which might be good for ping time, but not so good for the data rate test, and, not all speedtest servers are equally capable for high speed tests. Please connect directly to the modem and ensure that you are using a fairly short Cat 5e or Cat 6 cable.
Just to note, stepping up in speed, especially to Gb/s rates takes some homework to ensure the the pc, or laptop that you are going to use and test with is capable of handling the higher data rates. That extends to the processor, memory and hard drive as well, not just the ethernet port. While the port may be built to handle 1 Gig connection rates, that in itself is just a signalling rate. The real difference will be seen from what's behind the port, in the rest of the pc or laptop. It just might be that the pc or laptop you're using won't go any faster in terms of data rates.
Having said that, lets have a look at the signal levels at the modem. Can you log into the modem, navigate to the STATUS .... DOCSIS WAN page, copy the Downstream and Upstream tables and paste them into a post. That will paste in the text contents of the tables, so you don't have to include an image or post an image somewhere. With adequate signal levels and a pc or laptop capable of handling the higher data rates, you should see something in the high 800s to low 900s. Fwiw, the best I've seen to date is ~940 Mb/s.
Your signal levels aren't bad. The downstream is down instead of sitting at 0 dBmV across the board, but, that shouldn't cause any problems. Signal to noise ratios are fine as are the Upstream Signal levels. Only thing that I can think of is modem provisioning and the end devices.
I would call tech support and ensure that the modem is provisioned for 1 Gb/s down, 50 Mb/s up, and not accidentally provisioned for 500 Mb/s down, and maybe 20 Mb/s up.
Beyond that I doubt that the surface pro 3 could handle Gb/s rates. It might, but I think I would be pleasantly surprised if it did. The desktop, I would need more info, possibly the exact model number so that I could have a look at the specs. If you have a link handy for the desktop, that would do as well.
Can you run a speedtest using http://speedcheck.rogers.com/en.html I've seen results lately with extremely large variations between the Rogers and Speedtest.net results which don't make sense, so, if you could run a rogers speedtest as well that would be appreciated.
You could also try the following experiment. Switch the modem into Bridge mode, connect the R7000, running in full router mode and disable IPV6 in the router. Reboot the router, and the desktop in that order and run a speedtest using both speedtest.net and rogers speedtests. Before you switch the modem into Bridge mode, can you have a look at what Software (firmware) version is loaded as indicated on the STATUS page when you log into the modem.
@amp3d is that the XWRT-VORTEX version that you're running? Just want to be sure.
Can you take a read thru the following post which I wrote for a CGNM-3552 - Asus AC5300 combination. If you read thru to the end you will see the results of the various steps. As you're running Merlin, the same post applies. The exception is that the XWRT-VORTEX version does not have the Trend Micro protection on board, which is located in the AiProtection section of the firmware menu. So, that should not be a factor here for that firmware version. Other than that, the same ideas and issues will apply.
