@H-Mac Rogers does have Antronix signal amplifiers that are used. One of them can be seen in the following post from tonight:
Re: Dropped frames trying to live stream - Rogers Community
I discourage the use of amplifiers, as they're a Band-Aid solution. The real solution is to address the signal loss itself, which is usually caused by degradation of the external cable that connects the house cable system to the local tap. Just for clarification, do you have one of the older Hitron modems, or are you using the newer Ignite XB6/XB7/XB8 modems.
Have a look at the following page which shows the Rogers modems:
Find the Right Home Internet Service| Rogers
The modem grouping on the right is the Hitron modem group.
The left hand modem of that group is the CODA-4582. The right hand modem includes modem such as the CGN3ACSMR and others, up to the CGNM-3552.
If you have the white CODA-4582, you won't be able to log into the modem using an IPV4 address. An IPV6 address should work. To determine that address, at a command prompt, run an IPV6 trace to anywhere:
tracert -6 www.google.com
With the modem running in Gateway mode, the first IP adddress will be the modem's address. Copy that IP address and use it in a web browser address bar to access the modem's log in page.
If you're running one of the black CGN3xxxx modems, you should be able to use 192.168.0.1 as the modems log in address.
In either case, log into the modem and navigate to the STATUS ..... DOCSIS WAN tab. Copy the signal level tables, from the Downstream overview line, all the way down the very last character in the right hand cell of the bottom table row.
In the CODA-4582, that bottom table is the OFDMA Overview table. In the other modems, that bottom table should be the Upstream Overview.
Place your cursor just in front of the Downstream Overview line, hold the shift key down and scroll down and to the right, until you end up just after the very last character in the bottom right hand cell of the bottom table. Release the shift key and use Ctrl c to copy the data. In a post, use Ctrl V or the Paste commend to paste the data into the post. Those signal levels should show if something is really amiss with your signal levels, which might explain the blacked out channels. I wouldn't expect just two channels to be blacked out, but, looking at the signal levels might explain some of this, or it could point to a head end issue of some type.
How's your internet performance these days?
The lobby camera is an integration issue that needs to be looked at. I suspect that Rogers is probably responsible for this, but, I doubt that they have any interest in resolving it, and its possible that there's been such a turn over in field techs that they don't have many tech with experience in those systems anymore. It all depends on who has the contract to service the building's cable system, Rogers or someone else. If your lobby camera doesn't work, I suspect that it would be the same for other tenants. Have you asked any of your neighbours to see if they have any success with this? You probably have to complain to the building management to see that its addressed.
Ok, with the modem in Bridge mode, use 192.168.100.1 as the modem's IP address.
Your RT-N66U should be using some IP address other than 192.168.0.1 so that when the modem is in Gateway modem, with the router behind it, (a rather unusual configuration) you can still access the modem to flip it back into Bridge mode.
@H-Mac nope, not suggesting that at all.
There are two IP addresses which are used to access the Hitron modems:
1. 192.168.0.1 when the modem is operating in its default Gateway mode:
2. 192.168.100.1 when the modem is operating in Bridge mode.
When the modem is operating in Bridge mode, a smaller subset of functions are available thru the modem's UI. The firewall, wifi, and other functions are turned off, so, those portions of the UI are not presented to the user. That leaves the Status data, including the modem signal levels, reboot/reset capability and the ability to enable the Gateway functionality, which causes the modem to reboot back into Gateway mode with all of its previous settings intact.
Logging in to the modem, when its in Bridge mode will not result in the modem shifting back to Gateway mode. That is a deliberate action that the user has to select, and then save, in order to complete the transition from Bridge mode to Gateway mode. You should be able to navigate around the modem's UI in Bridge mode just as you are able to do so in Gateway mode. Anything that you change has to be saved (a deliberate action) in order for the change to be effective.
So, you're able to log into the modem to check the signal levels and then log out of the modem when you're done with it. The modem will remain in Bridge mode.
As for the RG-59 cabling, yup, that could be a problem, depending on how long the cable run is. While you're looking at this, if you're in a house, take a look downstairs where the house cabling converges. In newer homes there is usually a structured wiring cabinet which holds the starting point for the house telephone and tv cables. This usually where the external, inbound cables are connected to the house cabling. Depending on the age of your home, you may or may not have one of these.
The cable jacket would have the cable type printed on it. So, by examining the cables downstairs, you should be able to quickly determine what is installed in your home.
Ideally, all of that cabling , from the point where it connects to the external inbound cable, up to the modem, would be RG-6 as RG-59 has higher losses. Here's an overview of the signal losses between the two:
RG 59 Signal Loss (in dB) per 100 ft
Loss at 50 MHz: 2.4 dB
Loss at 100 MHz: 3.4 dB
Loss at 400 MHz: 7.0 dB
Loss at 900 MHz: 11.1 dB
Loss at 1000 MHz: 12.0 dB
RG 6 Signal Loss (in dB) per 100 ft
Loss at 50 MHz: 1.5 dB
Loss at 100 MHz: 2.0 dB
Loss at 400 MHz: 4.3 dB
Loss at 900 MHz: 6.8 dB
Loss at 1000 MHz: 7.0 dB
Ok, that's odd that you can't access 192.168.100.1, but, not entirely unexpected.
What happens with you ping 192.168.0.1 and 192.168.100.1
Food for thought, Rogers has apparently switched to IPV6 for modem control purposes. I know that the CODA-4582, with its current firmware version can't be accessed using an IPV4 address. That has been fixed in later versions apparently. I wasn't expecting to see the same issue with the other Hitron modems.
In theory, an IPV6 address should work, but, the IP address for the modem can't be determined when the modem is operating in Bridge mode as it doesn't show in a trace. You would have to reset the modem back to Gateway mode by running a manual factory reset, set the modem up again just to access it, and then flip it back to Bridge mode when you're done. I doubt that you want to go thru all of that.
You could call tech support and ask them to run a signal check on the modem, just to see what turns up, or, you could send a message to @CommunityHelps to do the same check. You would need to send in your account number and MAC address off the back of the modem, and ask the moderators to have a look at your signal levels.
Ok, temporarily stumped. I've used an RT-AC68U, AC86U and now an AX86U and I've never had any issues reaching the modem thru the router. I know that in some cases, its necessary to use a static route to access the modem. I've never set one up so I don't know the specifics of setting one up thru the routers UI. It shouldn't be difficult to do.
Are you running stock firmware or Merlin's firmware?
The last resort is to connect directly to the modem, which I do not recommend except for very very short time periods due to the constant scanning of Rogers IP address by miscreants around the world. They're always looking for unprotected ports to hack computer systems, so, you have to be absolutely sure of the pc's ability to protect itself. So, not for the feint of hart, and not recommended by me.
At this point I don't know if the problem is caused by Rogers switching to IPV6 for modem access on their part, or if its an access thru the router issues?
Tech support should be able to indicate whether or not the signal levels are acceptable. Be ready for an upsell to the Ignite modems. You can simply say "Thanks, but not at the present time".
Just to note, your router is out of date, way out of date. Its on Asus's End of Life product list:
https://www.asus.com/event/network/eol-product/
The last Merlin firmware version for that router is version 380.7 which was released on 8 Apr 2018, so that version is over 4 years old. At the present time firmware version 386.7_2 is in use for other Merlin supported routers, with 388.1 under development by Asus and Merlin.
https://sourceforge.net/projects/asuswrt-merlin/files/RT-N66U/Release/
So, not that I'm pushing you to spend money on a new router, but, its time to retire your much loved N66U and buy a supported router. By now that router is an online hazard, given the rapid pace that hacking tools are being improved by hackers around the world.
@H-Mac Rogers uses Antronix splitters these days. The splitters in question are CMC400xH (for horizontal). There are vertical versions as well. These spitters are rated for DOCSIS cable ops up to 1218 Mhz. I've seen a couple of posts with Orthogonal Frequency Division Multiplexing channels which could run up beyond 1005 Mhz, which has been the traditional upper end of the DOCSIS spectrum. At the present time, your modem can't use anything above 1005 Mhz, but, if and when you do move up to the newer Ignite modems, you won't need a splitter as the Ignite modem does it all, internet, tv and telephone. For the present time, it appears that these splitters are the type that the techs have on hand.

If you happen to see a Rogers tech someday when you're out and about, stop and ask him or her for a two port splitter, if that happens to be the splitter size that you need.
Fwiw, have a look at the cable ends, looking specifically for oxidation of the surface of the copper center conductor. If you happen to have any sandpaper handy, you can use a small piece to remove that oxidation. Don't over do it, as the center conductor has to fit snuggly into the barrel of the splitter. The copper centre conductor doesn't have to be super clean, as in shiny gleaming copper, but, clean enough that you have removed most of the oxidation.
There's a good chance that when you changed the splitter, you may have taken off some of that oxidation. It doesn't take much.
If you can get one from a Rogers tech, it shouldn't cost anything. There are other sources of course, such as:
Antronix itself:
https://antronix.myshopify.com/products/cmc4002h
you can use a CMC2002H which is a splitter rated for 5 to 1005 Mhz. This is suitable for the modem that you're running:
thats a two pack and it looks like its the least number of splitters you can buy for that type;
there's also AgCables, which is based in Stittsville (West Ottawa);
https://www.agcables.ca/products/splitters-cmc2002h
So, there are alternatives. I'm suggesting obtaining one at no cost, if you happen to cross paths with a Rogers tech.
