CODA-4582 - Open Issues for Investigation

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

Re: CODA-4582 - Open Issues for Investigation

Yes the issue was fixed ,this is a new issue now happ this morning since the docs 3.1 update. Look like I just got the .23 firmware and now looks like that channel went back up to 37. Should I factory reset the modem now that .23 firmware got pushed

Running fine with the .23 Firmware after a Factory Reset and a Reboot. I also see a few extra settings in the UI.

@RogersDave I exchanged for the black dot CODA a week ago and had all channels. Since .23 I am missing several downstream channels again.... is this a firmware bug or am I looking at yet another exchange? Please help...

I should add that I did a factory reset as well - still missing channels ...

One more thing - sorry. I noticed an option for the USB port.. I connected a drive and it showed as connected just once... and now no matter what I plug in - the USB light never comes on and I cannot access the drive whether it be a hard drive or a USB key.

I wonder if you could have the same issue I have/had.

 

My non-black-dot modem stopped getting some channels, but in .20, those channels still showed up as 64-QAM erroneously. In .23 they seem to have fixed that bug, so the unavailable channels don't actually show up... 

 

 

Maybe it's the same thing with yours and the channels were never there, but this now-fixed bug made them show up...

Not sure - but my thought was that the black dot modems were supposed to correct this disappearing channel problem.. speeds were awesome initially once .23 was installed - now they are worse than before... I'm not really sure what to do. This modem is the latest technology but I just can't believe how poor performing it is. Just click the help button under Admin-USB storage and check out all of the spelling errors. If this is any indication of Hitrons QC abilities we are in big trouble and this modem will never have its issues resolved.

Been hitting the League of Legends servers with alot of packet loss ever since the switch to the modem- never had any issue w/ League on the CGN3ACSMR. Now that the PingPlotter cosmetic bug is fixed, I ran a tracert to the League of Legends game server and hit it again with 50%-60% packet loss. Given that League is a very latency-sensitive game it is pretty frustrating to have your gameplay ruined because of this. 

Re: CODA-4582 - Open Issues for Investigation

I'm am missing channel 25 now all channels where there this morning don't know if the new firmware cause it but when you get a chance can you take a look thanks. @RogersDave

Enhancement request

 

Retested the WPS function on firmware 2.0.10.23- the WPS LED still stays green for more than 5 minutes after establishing a connection with a device. I, incuding others would probably like to have it stay green for only 1 minute after it has established a connection with a device, this way connecting multiple devices and wireless extenders would be much more faster.

Thanks @RogersDave

 

My modem was updated to .23 and the issue on TP-Link C2600 when CODA is in bridge mode is already fixed.

I can already use my own router. I factory reset the modem through the back and restored my setting. I backed it up before factory reset.

 

Speed is the same. All channels are complete. My modem is the 1st CODA.

 

Does the issue on puting the router to a certain distance from the CODA already fixed?

I belive that if you are showing a value for FFT type (other than N/A) in the OFDM Downstream Overview section, you are on 3.1 downstream.

So when are we expecting Rogers internet to work without issues?

My internet speed is so erradic. I regret it now jumping on Rogers 3 months ago and signing a contract. I should have waited as Bell Gigabit fibe is apparently available in my area now.

My neighbor friend installed it a month ago. He gets 1.33 Gbps download and 130Mbps upload. Crazy and yet reliable. I checked it myself today. Meanwhile I am sitting here at below 100Mbps at 950Mbps plan (upload is less than 5Mbps) since wednesday.

I contacted Bell to inquire about the pricing. They said they would give me Fibe Gigabit bundle package for $5 more than what I am paying Rogers right now (after adjusting for their price increase in Feb).

@RogersDave having issues internet just stops working it says I'm connected but I get disconnected and pages just load on wifi and wired connection it would last about minute then be okay then it will happ again since new update.

Quick question -- What's the latest version being pushed to routers?

 

It appears I'm running 2.0.10.23 and I haven't found any logs/first post info that has anything about this version!

 

o.O

I am on the 250u. Modem it CODA-4582 on V 2.0.10.19 just got this hoping this may fix my problum but it also did the same thing on the cgn3acsmr. This is with a wired conetion. I have tried this with out using my router (netgear R7000 with Asuswrt Merlin) and does the samething. I have also tried this at my friends house and does the same thing he is also on the 250u I think he has the cgn3acsmr modem. It shoud not be doing this. I have also tried this test on a bell 25/10 and the pings go up like 2 ms. Rogers NEEDS to improve this ASAP this dose not look like a isolated problem with my testing. 

 

Thanks Dan
