Good morning Community,
As I mentioned in a post two days ago, we have received the next firmware 2.0.10.20 from Hitron. We are currently running initial testing on this version and will push it out to participants in the firmware trial program as soon as it passes initial testing.
However, while running these tests, we discovered abnormal behavior with ICMP and are awaiting feedback from Hitron today to asses how this will be addressed. As soon as I this is confirmed, I’ll update the change log with the correct version information and start pushing it out.
In parallel, we are still working on the following high priority items. In some cases below, I requested affected customers to reach out to me via private message. If you do so, please include your modem MAC address in the subject line (even if we exchange messages daily) as there are a lot of you reaching out to me daily 🙂
UDP Packet Loss
The investigation for what has been reported as UDP packet loss is still ongoing. We have deployed a probe at one fellow forum member on both a CODA-4582 and a CGNM-3552 to collect additional data. We are actively working with Hitron and Intel on the results observed.
Based on what we know so far, in most instances UDP packet loss is coupled with higher uplink usage in the area. Although the impact is noticeable in specific logs (League of Legends), the root cause for the perceivable impact (while playing) is likely related to bufferbloat (see next issue).
Bufferbloat
When comparing the performance of a CODA-4582 to a CGNM-3552 in the same network conditions, the CODA-4582 consistently reports higher bufferbloat when tested on DSLReports.
Update April 12: The solution for this problem will come in two folds. It will require a change in software which will possibly be included in 2.0.10.27 but more likely in 2.0.10.28 and a change in network configuration.
The network configuration change is not compatible with the current firmware so this change will only come after a vast majority of the modems are running the new code. We are however looking at a way to make the change only for specific modems to support testing in the community.
Update April 22: This problem seems resolved in firmware 2.0.10.27
5 GHz WiFi Low range for channels 36 to 48
Lower WiFi channels on the modem have a much smaller range. This is due in part to the limit imposed by Industry Canada to maximum transmit power.
Furthermore, the current automatic channel selection (auto mode) tends to select the lower channels when in similar load conditions.
Workaround: manually select higher channels (149-153-157-161)
Update April 22: The channel selection algorithm has been improved in firmware 2.0.10.27
Loss of OFDM Channel Lock
Under some RF conditions, the modem fails to lock properly on the OFDM channel. This typically result in variable performance.
Update April 12: This problem is resolved in 2.0.10.26T2
List of connected device does not get fully populated
This is a known issue that has been tracked since firmware 2.0.10.13. We are making improvements at every firmware but it is not a perfect system.
The situation is worst after a reboot or firmware upgrade as the list gets reset and must be repopulated as devices renew their DHCP lease.
NAT Loopback not working for wired clients
When setting up port forwarding to an internal server, it is possible for a client on WiFi to reach the server using the external IP/port. If the client is on a wired interface, it doesn't work.
Update April 12: This problem is resolved in 2.0.10.26T2 (not confirmed)
LAN Counters not working
Some customers reported that LAN counters (especially in bridge mode) are reporting inaccurate values.
This problem has been reported to Hitron for investigation.
Unexpected modem reboot
Some customers reported their modem reboots unexpectedly. We have also seen this behavior in our lab.
Update April 12: This problem is resolved in 2.0.10.26T2
Missing SC-QAM Channels
After a reboot, some modems are missing SC-QAM channels. A fix has been implemented in 2.0.10.26T2 to address this behavior but it has not corrected all scenarios.
Investigation continues with Hitron.
WiFi Survey
The WiFi Survey functionality in firmware 2.0.10.26T2 (and possibly before) reports incorrect SSID names.
Guest Network
When connecting to the Guest Network, an error message is displayed "only allow DHCP client to use this wireless". This has been reported in firmware 2.0.10.26T2.
Update April 22: This issue has been resolved in firmware 2.0.10.27
Update May 2: It seems this issue is not fully resolved and still experienced by some users
Future Planned Improvements
The following are items that we are working on in parallel of the above.
- Improvement in WiFi speeds
- Improvement in latency / bufferbloat

There should be (I haven't tested or seen it myself so for now it's hearsay). However, it might not come from day 1 of firmware 2.0.10.27 as we need to push a secondary configuration to the modems as well and I'm still trying to figure out how to do that on the trial base only without breaking the entire network...

If my MAC address is being ilegally misused by someone else what are the radical measures i need to take to end this forever?
Ask Rogers to change my IP?
Would just exchanging my modem will change the MAC address?
Any settings I need to change?
is the MAC address the same forever whether i make some changes or not?
the MAC is wired to the modem if I changew it to wifi would that solve my problem?
I would appreciate your knowledgeable answers.
I will be calling Rogers today and as them what needs to be done
Thank you kindly.

MAC address is tied to your modem. Just take it in to any store and say that you need an exchange. Don't change anything else that you are doing -- do the same number of speed tests, download the same things, visit the same sites as you normally would. Ensure that you are on the same firmware version too (if you are on the trial program, update them with your newest MAC). See if the usage disappears. I think we'll all be very interested to see if it drops back down.

I started but it's not complete. I'll need to test the firmware to update on this because of lot of this items are unclear to me.
From a user perspective, the Intel base firmware (SDK) should make a difference in multiple aspects. But we will have update the modem configuration file to take advantage of some of the benefits. We are however still working on getting a solution in place for trial participants.

Not sure if anything major has changed with the hops between me and the ingest servers I broadcast to but for several days after the .26 firmware update things were amazing. Since then it's gotten progressively worse with major dropped frames.
I've been running PingPlotter during my casts and the connection seems great minus the occasional packet loss at hops along the way (and it doesn't propegate - just happening at a single hop along the way). Someone had mentioned that PingPlotter only tracks ICMP requests where as broadcasting utilizes RTMP? Not sure if it makes a difference or if there's something you can track on your end (or tools you could recommend for me to troubleshoot) @RogersDave but wanted to mention it here.

There seems to be an issue with this firmware (2.0.10.26T2) in which the modem needs a factory reset after a power outage. Upon power restoration, my router (Asus AC3100) was unable to get a WAN IP from the modem. After factory restoring and rebooting the modem, all was fine.
The modem is on 2.0.10.26T2
Anyone else run into this issue?

I think it's the Asus, actually. I've found that either rebooting mine or just unplugging the WAN cable and plugging it back in again was enough for my AC3200 to get an IP again. I have experienced a similar problem and I don't think it's the Rogers' modem.

Without going too much into details just yet (I want to see the results first), firmware 2.0.10.27 might help you with that. If it doesn't, then I can troubleshoot further with you.

I don't know exactly but I heard that bufferbloat (at least in some situations) is greatly improved. That is the item that requires an updated network setting however but I now have a confirmation that I'll have a method to enable on a per modem basis (trial participants).

I am new in this forum and I have very limited knowledge on IT stuff.
Now here is my issue - My guest network was working fine. All on a sudden - every time someone tries to log in to the WIFI Guest network a message pops up - says - "
"only allow dhcp client to use this wireless."
How do resolve it and allow people to log into the guest network? Please help.

Hukka,
This is unfortotunately a known issue with firmware 2.0.10.26T2. This firmware brings a lot of improvement to connection stability and performance in general over the previous firmware but it did break guest WiFi.
At this point, there are 2 options for you:
1. If can downgrade your modem firmware back to the previous version (you will need to send me a private message with your modem MAC address and serial number, both printed behind the modem)
2. Register to the firmware trial program by sending a private message to @CommunityHelps with the same information as option 1.
Option 2 is by far the best but you will have to wait until Monday when I'll start pushing out the latest firmware (2.0.10.27) to everybody which resolves this issue.

I am on the CODA 4582 one black dot. Regular customer not on the trial program.
Two days ago my version changed from .24 to the .26T2
My speedtests with speedtest.net by OKRA to the Rogers Toronto server clearly show worse speeds (lower in general, but mostly on the download signals). Around the 300's Mbps even during 24:00 to 04:00 hours -in the wee hours-.
Abysmal speeds and the lack of speed consistency is very noticeable. From the speeds I see in here .26T2 is a regression from .24
With .24 I was seeing more often than not download speeds hovering 900Mbps at times. There were all over tha map during all times of the day between 250 and 900 Mbps.
Since March 29, 2017 and after 4 months since I signed into the Gigabit package the BIG issue with my speeds throttled to max 30Mbps they now seem to have been fixed. Now even with the downloads unaceptable low speeds, uploads seems to mostly be stable around the 45 to 50Mbps marks.
But as i said I am absolutely uninpressed with the results with the .26T2.
Is it a known issue that .24 had higher download speeds than .26T2?
Luckily I am not a gamer so in that respect I am not affected by what others report as their problems with gaming.
Any specific suggestions to fix my issues RogersDave?
Is the .27 version going to solve my current speed problems with .26T2?
Thank you
