CODA-4582 - Open Issues for Investigation

*** This post was last edited May 2, 2017 ***

 

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

@notregistering can you run a modem restart/reboot now.  Pull the power, wait for 30 seconds and plug the power back in to force a restart.  After that, check to ensure that you have 32 DOCSIS 3.0 channels running and the DOCSIS 3.1 channel as well.  If you have any issues after the restart, consider running a factory reset.

No entries in DOCSIS Event log (and modem doesn't reboot – has been up for almost 4 days now with no speed degradation!!). Almost like modem having trouble finding the right IP match for the device; so... DHCP issue???

 

Also, perhaps related to this, saw the following in the event log today:

 Question to everybody, is this a new thing that you have observed only on 2.0.10.24 or something that existed before and need to be adressed by Hitron?

 

It has never been reported before so I just want to ensure it is reported correctly.

For me just with .24 I had started to see this.


@RogersDave  for me i have only noticed it on .24, but i wasn't on other versions very long.

    It has happened a few times now, the computers are connected to the router, just no access to internet. Last time it happened, internet came back without rebooting, the first few i had to reboot. Always noticed it in themorning, after little or no activity during night.

   If happens again, i'll try to get more info on this. Its always been mornings just before work, not much time to play with it.

@RogersDave

I believe this has happened since version .21 firmware. Again, it only happens when the connection is inactive for some time.

I've been here awhile

Got this modem today and having a few issues with it at first. Twitch.tv was rebuffering every 5-10 minutes. NHL game center froze twice during the first period of the Edmonton Flordia game. Had no issues prior to upgrading.

 

Is there a way I can get on the latest firmware?

@merms, @hen555, @ghost1001, @MegnaGaming, see the following post to request the latest firmware for the 4582:

 

http://communityforums.rogers.com/t5/forums/forumtopicpage/board-id/Getting_connected/message-id/427...

 

 

That request will also place your modem on the trials list for future trial builds and on the exclusion list to prevent the firmware from rolling back due to the nightly or weekly firmware check that runs across the network. 

 

Re: CODA-4582 - Open Issues for Investigation

@Datalink I did request (and was approved) several days ago. Still waiting on the updated firmware. I was told be a CSR via Twitter that they would expedite this because the problems are impacting how I make a living.

Still not on 0.24

Yea, I did that to get back on the beta program after I swapped modems for a new one. I'll PM them again and put an extra note to ensure that I'm on the exclusion list.

Re: CODA-4582 - Open Issues for Investigation

@MegnaGaming, ok understand.  If that still isn't done, I'd call tech support or get back on twitter to have them push the firmware tonight.  Note, that this isn't normal ops for the CSRs to push trial firmware.  That is usually done thru @CommunityHelps and crew, or directly by Dave.  Also note that the request still has to go in thru @CommunityHelps to ensure that the modem is placed on the exclusion list, otherwise it will roll back during the night to the latest production version which is currently .19

@RogersDave I think this has been since .21 firmware, but I am not positive, since the main troubleshooting with .21 was the frequent speed degradation and need to constantly reboot. As others have said, it only seems to happen when the connection is inactive for some time.

I know there's a lot in this thread, but if you can read through it (or at least the first couple pages and last 25 pages) you might see your problem already addressed here.

 

Specifically what problems are you having? Where are you speed testing? Can you share the results? When did you get your modem? Does it have a black dot by the power socket?

 

Please log into your control panel (192.168.100.1, username cusadmin, Wifi password as your password) and then post the system information (hardware, software items only) and DOCSIS WAN page (entire page).

Re: CODA-4582 - Open Issues for Investigation

The problem is my speed is not to what im paying for. Ive done several tests on speedtest.net and ive averaged around 200-400 mbps. I have a black dot on my modem beside the the mac addresses.

I know some of you got downgraded back to 2.0.10.19. I'm really sorry for that. I pushed the upgrade to thousands of modems over the week-end and may have missed a batch in the exclusion list.

 

I have re-upgraded you and correctly added you to the list.

 

I also processed most trial firmware requests up to the ones received Sunday. I will handle the rest today.

 

Now, the firmware 2.0.10.24 is scheduled to go live in production today (unless something major comes up) with automatic upgrade on boot. Once this is done, all that will be needed is a reboot of the modem (or for a new modem to plug it in) to receive the latest firmware.

Re: CODA-4582 - Open Issues for Investigation

This is my third Hitron CODA 4582 in two days. Technical support switches on the guest network but as I cann not  connect to the guest network,  they ask me to change the Modem.

This is the third Modem and I still cannot connect. It is important for me.
