Thanks for the reply!
1. We're on Ignite 500u which is 500 Mb/s Down, 20 Mb/s Up. The Gigabit is listed as an option but is +$30/month. It's what I originally signed up for on Live Chat, I didn't feel like $30 more is worth going from fast to lightning fast aha
3. it's on 220.127.116.11, I tried asking for a newer one but I think I have to join the trial for that?
4. I get this: "Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received - T4 time out;CM-QOS=1.1;CM-VER=3.1;" - all the time among other errors.

6. By provisioned do you mean what speed being sent to the modem? During speedtests on speedtests.net it can reach 600mbps if I'm lucky but it ramps up to it incredibly slowly most of the time but is usually stuck around 300mbps all day.
7. Running it for 5mins didn't show any packet loss but I'll run it longer.
8. Right now the CODA is in bridge mode but I recently tried enabling IPv6 on my ASUS router with the setting on 'Native', it didn't change a thing with the connection. I had tried changing the CODA between the different settings as well 'Dual, IPv4, IPv6' without the ASUS and it didn't make a difference.
10. From what I can see it looks like the coax comes in from outside, goes into a two-way splitter, then there's two coax cables connected to it, one goes upstairs to one 4K Nextbox, the other goes to a splitter that's a double -3.5dB where the 2nd 4K Nextbox and the CODA are connected. The CODA is in bridge mode and connected to my ASUS router with a CAT 6 cable, they're basically right next to each other. I've tried other ethernet cables too, nothing helped. The cabling in the house is RG6 and the CODA has one black dot.
@Hendrycks can you delete the CM-MAC=xx:xx:xx:xx:xx:xx data? That is specific to the modem and shouldn't be left out in an open forum.
To answer some of the questions:
3. Yes, to run a trial version you would have to sign up for the trials program, which isn't a big deal to do.
4. As indicated in the mac addresses, your modem is connected to a Casa Sytems CMTS, so, you would be able to see much faster rates from that CMTS.
5. The modem is using DOCSIS 3.1 on the downstream, DOCSIS 3.0 on the upstream as DOCSIS 3.1 on the upstream side will be deployed in a few weeks (hopefully). That shift from 3.0 to 3.1 should improve the upstream rates. So, the DOCSIS 3.0 downstream signal levels and signal noise ratios are ok even though the modem isn't using those channels. The modem is using the OFDM downstream channel. The frequency and power data for the OFDM channels is not correct as shown in the user display at the current time, but, apparently tech support can see the correct OFDM data.
The upstream signal levels are a little high for a modem thats running DOCSIS 3.1 on the downstream. The CMTS is in charge of the upstream signal levels and commands the modem to increase or decrease the power output level to meet an inbound 0 dBmv signal level at the CMTS. I believe the signal to noise ratio of the upstream channels at the CMTS are supposed to be 25 dB or greater. So, its a little interesting that the upstream levels are running at 40 dBmV instead of the typical 30 dBmV that I've seen with this modem. You could ask tech support if there is any noise issue with your modem and with your neighbors modems that run off of the same local tap. Usually there are around 4 to 6 homes running off of the same tap. You or one of your neighbors probably has a waist high cable pedastal just off of their driveway, or you're connected to the same tap at the utility pole. If there is a noise issue that would explain the higher output power at the modem, and might explain the upload rate instability.
6. Its strange that there is a slow ramp up on the speedtest. That should pop up pretty quickly and stay at the final level for the majority of the test.
7. Running Pingplotter for a 24 hour period will show the base ping time (latency) in the very early morning hours and the potentially higher times in the late afternoon and evening. That higher latency would be an indication of upload congestion at the CMTS, which will result in slow download and uploads. Keep in mind that TCP/IP is essentially a send and respond type of system. A packet is sent by the CMTS, the modem responds, "Ok, send the next". If the upload side is heavily congested at the CMTS, that will slow the response time and potentially result in a retransmission by the CMTS, slowing this down even further. So, the pingplot can be used to some extent to determine if latency is a problem at your CMTS, but it needs a long run to see the changes in latency that occur during the day. Just to note, the latency changes on a day to day basis, so, although you can generalize, low latency in the early morning hours, higher latency in the afternoon and evening hours, those times where you see higher latency will change from day to day.
8. Are you able to get IPV6 running on the router? The following settings can be used:
Connection type Native
IPv6 LAN Setting
LAN IPv6 Address No entry this will fill in on its own after a reboot where the router negotiates with the CMTS.
LAN Prefix Length No entry this will fill in on its own after a reboot where the router negotiates with the CMTS.
LAN IPv6 Prefix No entry this will fill in on its own after a reboot where the router negotiates with the CMTS.
Auto Configuration Setting Stateless / Stateful I've tested both in the past and prefer to run stateful as it offers more protection for IPV6 operations
IPv6 DNS Setting
Connect to DNS Server Automatically Disable If this is enabled the router and connected devices will use ISP's IPV6 DNS
IPv6 DNS Server 1 2620:0:ccc::2 (OpenDNS) Note: these can be set in a different order, or, you may
IPv6 DNS Server 2 2620:0:ccd::2 (OpenDNS) prefer to use your own IPV6 DNS.
IPv6 DNS Server 3 2001:4860:4860:0:0:0:0:8888 (Google)
Auto Configuration Setting
Enable Router Advertisement Enable
Note that after you fill in or enable the settings as shown above, you have to reboot the router so that it picks up the IPV6 IP address from the CMTS.
10. With that cable setup you have a -7 dB drop from the incoming cable to the modem. Thats pretty interesting as it would put the original signal levels around 10/11 dBmV. Thats a little high and it could probably be dropped with an attenuator, however, over time, as the external RG6 or RG11 cable degrades, those levels will very slowly drop, so, having them above 0 dBmV to start with is fine, 10/11 dB might be a little too high.
Are you running the 2.4 Ghz network on the router? If so, separate the modem and router using something like a 10 foot Cat 6 cable. I have mine connected in that fashion, sitting about 8 to 9 feet apart. The modem does have additional shielding to protect the DOCSIS tuner from the 2.4 Ghz networks, but, this is worth experimenting with, to determine if the routers 2.4 Ghz network is causing some grief for the modem.
@RogersDave - I'd like to remind you that on April 21st, you specifically said firmware 18.104.22.168T2 was known to have the Guest WIFI bug and "..wait until Monday when I'll start pushing out the latest firmware (22.214.171.124) to everybody which resolves this issue". Of course we now know firmware 126.96.36.199 did not resolve the bug. Then I was told firmware 188.8.131.52 would resolve the bug. Again the same thing. Come on, a regression bug that has existed at least since April, and it still exists after all this time, numerous releases, and countless assurances?
I do not know who is responsible for what and perhaps your hands are tied. However, obviously patiently waiting means no results, so who do I need to escalate this to?
I have version 29 but I don't have the USB functionality displayed. Could you please push this functionality to my modem?
I have CODA modem
Every couple hours lost IPv4 address(no device can get IPv4 address, IPv6 is okay)
reboot doesnt help
set IP stack from Dual to IPv4 only doesn’t help.
to fix, only way is to factory reset modem and re-setup again.
im on regular gateway mode, please fix.
I set a manual IP address on one computer and it resolved the issue, so you could try that.
Hello @RogersDave and others
Could someone please tell me what the fastest speed the Rogers Coda modem supports for wifi? I need to get a USB 3.0 wifi card and wanted to know what speed to get.
Also, any recommendations for a wifi card would be appreciated. I currently have this one and want to upgrade it: https://www.linksys.com/us/p/P-AE3000/
