Packet Loss and excessive Ping times
CODA-4582 Modem in Bridge Mode. - Commercial Router and computers hardwired
I know it sucks, but can you try in gateway mode without your router in the picture? Also try with a different computer, just to ensure that it's nothing with your setup.
I've recently switched to the gigabit plan with the CODA-4582, and I'm having serious issues with my download speed.
Starting with firmware .13, I did a speed test, and the results were excellent. Signed up for the beta firmware to receive .24, and there was a definite speed loss on the test, but I chalked that up to network traffic.
From there I switched to bridge mode and my router, only to find a slightly higher ping than I was expecting, but then also lag swings that made games completely unplayable. (Since then, I've disconnected the external router entirely, to take it out of the troubleshooting equation.)
Having done a number of factory resets and power cycles, this is the graph of all the speed tests I've done, mostly using a single machine over ethernet directly to the modem.
I'm open to any ideas, here.
This is the DOCSIS WAN info (I have an IPv6 address, but not 3.1 enabled, as far as I can tell)

Packet Loss and excessive Ping times
Might I suggest editing your post ASAP to remove those links as you're leaving your IP address exposed for all the internet to see.
Are you very familiar with PingPlotter? There are a lot of great articles that provide some detailed explainations of results you're seeing. Unfortunately when I attempted to download the data file it only gives about 1 minute of the original data so unfortunately I can't troubleshoot too much.
Just going off the images attached,there appears to be major latency at hop 9. I would suggest trying to ping Google or Rogers. Secondly you seem to have major packet loss happening at your router/modem (50%) but upon closer inspection it seems you may be pinging REALLY frequently. Do you have your interval set to 0.5 or 1 second by chance? I suggest keeping it on 2.5 seconds.
If you want more help with PingPlotter, send me a DM and I can take another look!
I would suggest the following:
- factory reset the modem
- turn off the 2.4 Ghz band
- Connect a CAT 6 or CAT 7 cable in port 2 into your PC and run some speed tests from these sites:
You should be getting good speeds and if not, it could be congestion on your node. Contact Rogers Support and they can troubleshoot things for you.
Havent been fully watching this thread, since I didnt have this modem, till this weekend.
My original CGN3.. well started to go wonky. Where it was still conntected from rogers side (uplink/downlink, etc still there, rogers could see it) but no LAN side.. no connectivity at all from wired/wireless/static/dynamic. Cant get to the modem interface. Swapped it out and was given a new CGN3, and same thing, something wonky with the current firmware?
So was swapped out for the CODA.
Generally that one was working fine for about 1/2 the day. Then thats when stuff started getting wierd.
Not in bridge mode.
Randomly, a good chunck of the devices.. would not be connected.. well they would connect to the wifi.. but not getting an IP address properly..
Any of my devices which were IPv4 only. Were connecting fine.
Anything which had a STATIC IPv4 addres, was fine.
The issue seemed to be with devices which were on dynamic.. and getting both IPv4 and IPv6 addresses?
My iphone/ipad were ones which were effected. They are not able to turn on/off IPv6.. it appeared it got a v6 address.. but wouldnt keep properly the v4 address.
And from what i could find.. very little control over the v6 DHCP in the modem itself?
Since then.. swapped over to bridge mode. Using an Asus RT-N66U.
Currently, have v6 OFF with it.. just v4 only.. and appears to be working fine.
