Been running into what appears to be a node issue this evening. Have had a ping running against my first hop, which I'll assume is the node. Pings have spiked as high as ~500ms, but they're all over the place. No packet loss, just wicked ping spikes which are making me really suck at Rocket League (that's no good, that's never good!).
Most recent ping:
Ping statistics for 99.xxx.xxx.xxx:
Packets: Sent = 2321, Received = 2321, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 3ms, Maximum = 385ms, Average = 16ms
I'm network literate. Nothing going on my network, verified (I run a Sophos UTM gateway). Have rang pings from the modem to the gateway directly, same.
Can anyone help me out? What info can I give to assist?
Thanks in advance!
Solved! Solved! Go to Solution.
Despite the fact that I've posted PAGES of ping graphs showing the issue, Rogers today performed a 50 ping test to my connection and deemed the issue as "Customer specific" and closed my ticket. I'm at my wits end, and can't believe anyone with a network certification so naive to think that a 50 ping sample trumps a MONTHS worth of ping logs showing otherwise.
It's unfortunate to see that Rogers new emphasis on customer service seems to amount to no more than lipstick on a pigs behind.
Honestly, I'm not even sure why I stuck around to help Rogers find the issue - I should have just jumped ship as soon as it happened, but instead I thought that if I collected enough data and proof they could locate the issue.
@MIRRRRR what modem are you running, a black CGN3xxx modem, or the white CODA-4582. It its a black CGN3xxx, modem, can you have a look at the back of the modem for the product sticker which indicates which CGN3 model it is and please let me know what the modem model is.
Ok, for now you can't ping the CMTS which is the first hop after the modem. There is some issue with the modem which causes the first hop ICMP ping return to fluctuate up to approx 100 ms. If you have ping returns beyond that, there is something else going on.
What I would do for now is call tech support, ask the CSR to:
1. run a signal check on the modem; and
2. determine if the DOCSIS 3.1 OFDM channel signal level and signal to noise ratio is within spec; and
3. check the background noise level for the DOCSIS 3.0 upstream channels and OFDM channel.
Edit: I've been checking on this and there doesn't appear to be any effect for ICMP pings to targets beyond the modem. UDP performance is ok from what I can see so far which is important for gaming. I'm running a UDP out, UDP in test at the present time, which will take another 24 hours to run. I'll have a better idea of what UDP looks like after Friday night.
Tried that earlier. I was told there were 'pockets' on the node. Not going to lie, I didnt last long after that. Was told it should 'iron itself out'. OK?

Are you in a condo/townhouse/highrise or house? Your DOCSIS 3.0 signal levels are very high, which is unusual. The signal to noise ratios are ok, as are the upstream DOCSIS 3.0 signal levels. The OFDM channel info isn't correctly indicated at the present time, but, tech support has access to the correct info.
Detached house. Newer subdivision, maybe a dozen years old now.
Please add a post there so that @RogersDave can have a look at that in the morning. Put in a link to your first post this evening for reference purposes. To copy the post link, copy the link info for the post number at the bottom right of the post. Its a post number and link all in one. I don't think I can do anything for you tonight, but, Dave should be able to have a look at the modem and CMTS to see whats going on.
Edit: You're connecting to the modem via ethernet, correct?
I'll ask one of the mods to move this thread over to the trial feedback
Unfortunately, no access. I just swapped out a CGN3AC last week that was locking up every 20 minutes, and this is what they gave me at the Rogers store.
