I just had to do a hard reset of my Rogers modem, not only was the statistics page not available but there was a hard lockup where the front lights were showing sync and activity but no surf was able to be had. After rebooting the Rogers modem (white Hitron monolith) my RT-AX88U router started processing the magic sand again. I haven't ever had anything like this happen before so I will keep a close eye on it over the weekend and report if anything else is going on.
I'm in North Oshawa.

The only thing I see with this new Firmware is I don't see any DOCSIS Event logs? I rebooted the Modem 3 to 4 times.
My modem rebooted this early morning, around 4:00am. I also had intermittent outages this morning around 10:00am and I had to physically unplug the modem and plug it back in. I'm not sure if this is a firmware issue or due to OFDM/OFDMA enabled on my modem and testing is being done. Do you have any insight as to the latter? I know I cannot call Rogers tech support since I am a beta tester but I may need to be removed from the program as my son does online learning and cannot tolerate the outages during the day.
Thanks for the feedback on 18.104.22.168 provided so far, keep it coming.
To confirm in 22.214.171.124 we did not implement a fixes for either of:
We will be rolling out new code for our CGN3AC trial users over the next couple of days.
The new build 126.96.36.199 has 2 changes which are both geared toward the backend management.
Once you have had some time with the new code please let us know what you think.
Hi, looking at my modem AC it's running trial 188.8.131.52. Not sure if you had a typo or my modem will be downgraded?
@lethalsniper I don't recall if you have an OFDMA upstream channel running, but I don't believe so. In that case, the upstream channels on both modems are using 6 Mhz wide QAM channels.
The downstream channels are a different story. The CGN3ACSMR will be using twenty four 6 Mhz wide channels. The CODA-4582 will be using the OFDM channel with somewhere under 4096 sub-carriers, don't know the exact number. Using the downstream OFDM channel will result in a greater number of transmit time slots, however, the downstream loads have increased significantly, which counteracts the increase in transmit time slots.
Now, also keep in mind that Rogers may have assigned all of the OFDM capable modems to the OFDM channel, significantly decreasing the load on the QAM channels. I don't know if there is a mixed mode in operation whereby the modems use both OFDM and QAM channels for customer data or if the OFDM channel has the majority load of the customer data, for those customers who are using an OFDM capable modem. That would also explain why customers are see decreasing performance as the overall OFDM load has increased significantly since March 2017.
Looking back on some test data, there is a three to four times increase in the downstream ping times from the CMTS. I'll have to do a little more testing to get a better idea of what that number is, but, there is a significant increase in that CMTS to modem time frame, despite the use of the OFDM channel.
The end goal of the cable operators will be to remove the QAM channels and reassign the frequencies to OFDM channels, significantly increasing the throughput of the CMTS to modem portion of the system. That will take a long time to accomplish, just like removing analogue tv channels took a long time to remove. Its possible to run custom OFDM configurations around the QAM channels but I don't know if any cable operator is actually doing it.
For what its worth, and I've said this in the past, I think your apartment building has a problem with its cable system, and no amount of complaining on the forum will fix that. You need to be speaking with the building management and owners to change out the cabling and basement MDU's. The goal should be to install fibre. The copper cabling could probably be left in place and abandoned instead of paying to remove it. Pull fibre and install fibre ports in all apartments.
