Early morning test, can't possibly be node congestion before 6AM.. 357 / 11
Single client; direct connect to gateway in gateway mode (not bridge); IPv4 with IPv6 disabled; no DC3.1 binding; service provisioned at 1000/30; upload nerfed to around 8-12Mbps; download jumps between high 1XX and low 3XX; download test tends to started "faster" and then tail off slower.
Only custom settings I made to the modem are infinite DHCP LAN lease and custom DNS (18.104.22.168/etc.) 22.214.171.124 if any techies want to take a look while I'm at work
On a whim I ran more speedtests back to back to back to Rogers Toronto server after a modem reboot:
Test 1: 587/20 http://www.speedtest.net/result/5881326977.png
Test 2: 445/19 http://www.speedtest.net/result/5881331237.png
Test 3: socket-download01 error
Test 4: 427/18 http://www.speedtest.net/result/5881336531.png
Test 5: socket-download01 error
Test 6: 383/17 http://www.speedtest.net/result/5881343037.png
Test 7: socket-download01 error
Test 8: 433/17 http://www.speedtest.net/result/5881346335.png
Ran a speedtest this morning and it is back to a crawl:
No wifi internet access on either the 2.4 or 5ghz. I am on my second CODA in two days, not really confident in switching to a third. Can you help??
Good morning Community,
It has been a busy night and I couldn't follow all the messages being posted but I'll try to summarize the main issues that were reported here yesterday and overnight.
Modem rebooting automatically: in most cases, these are modems that were activated on Tuesday or Wednesday that had IPv6 enabled. The modem will reboot once to accept the new configuration file that disables IPv6. It should be a single occurrence, if it is more frequent, let me know.
5 GHz WiFi performance: There are some reports of poor performance of WiFi, especially on the 5GHz band. This is being addressed with some improvements coming in the next firmware, likely before Christmas (it wasn't ready to launch in time). I also expect further tuning in the upcoming releases. One important note is that the antennas in this modem are all located at the top of the unit. For best performance, the unit should be installed upright (when facing the modem, the Rogers logo should be at the top) with nothing siting on top of the modem.
Pixel and Pixel XL frequent disconnects: I have been tracking this one and collecting traces for Hitron and Google. I was asked yesterday for a set of traces to put a fixed IP (instead of DHCP) on the phone. Since then, I haven't experienced any disconnect. This may be a temporary workaround for some of you but still work in progress.
Speed issues: a few of you have reported horrible speeds. There are quite a lot of reports, too many for me to respond individually. We are trying to assess if it is a modem issue, an incompatibility issue or a core network or peering problem. In order to triage the results, would it be possible for customers affected to perform the following:
Report the following information:
I understand that speedcheck.rogers.com may not give you the best top speeds but it will help us determine where the issue lies. Also, step 1 and 2 above are quite important at this point of the investigation.
Thank you all for your assistance.
Trying to understand if I should be replacing the 3552 with the new CODA or wait?
3552 has been very stable, even if the latency isn't amazing.
Speed test shows ~860/40.
Speeds and ping have been alot better since I've upgraded to the CODA modem. I haven't experienced any of the issues mentioned here so far...
Will do tonight.
Can you clarify if it is critical that wifi (both) be disabled as well, to prevent other things from connecting to the modem other than the PC performing the test? Or is it mainly a PHY issue being looked at?
Note that I don't consider my speeds horrible (2XX-3XX down, 1X up) but it's notably different to before with the old modem, so it is worthy of analysis.
This is on a Gigabit connection, I do not have IPv6 enabled or (DOCSIS 3.1). My modem reboots itself a few times, and overnight the Wifi had no connection and my speeds went low as above after having 500Mbps+ download last night. My Voip phone is unusable which is my biggest issue with this modem when speeds go low.
