Upgraded from legacy 1Gbps to 1.5Gbps ignite now Internet is unreliable.

I plan to stick around

Going from the Hitron 4582u to XB7 about a week ago and ever since my internet has been very flaky...  reduced speeds, increased latency.   Its only been a week but I notice much more buffering on netlifx at night and sometimes long pauses hitting websites.  Ive lost connection on MS Teams calls on work.  This worked fine prior, so I am wondering if there is something going on.  Almost want the Hitron back!

 

I am not using the XB7 as a gateway, I changed it to bridge mode and use my eero pro 6 mesh system (which I used before).  Only change was the cable modem.

 

Putty my line stats in here:

In the logs I get the same error everyday at the same time.  All seemingly revolving around DHCPv6/IPv6...

Any help would be appreciated.

@BuddyRich your downstream QAM channels (1 to 32) are too high, in terms of their signal level.  The upstream is also high, but, within limits.  That's a very odd combination.  Are you in a house or apartment/condo/highrise?

 

If you're in a house, can you read thru the following post, specifically part 2 and then check the cabling in the basement to see what's present?  Please let me know what you find:

In a detached house.  Wires are underground in this neighbourhood.  Cable is just a regular RG6 cable from the outside to the modem though its attached to a grounding block similar to the other post but nothing else.  (ie no splitters, etc...).  No other coax...  This was a self install (no tech visit) as it was just a 1Gbps legacy with Hitron to 1.5Gbps /w Ignite.

 If both signals are "high" I could try putting a splitter (if I still have one kicking around) in there but would that degrade the upload signal too much, as you said its also high but within limits?

 

What confuses me is the hitron worked fine with the same linestats and I believe both the XB7 and it use the Intel Puma 7 chipset...

 

 

 

 

Re: Upgraded from legacy 1Gbps to 1.5Gbps ignite now Internet is unreliable.

Its possible that you have a Technicolor XB7.  I believe there are Arris and Technicolor versions.  I don't have the model numbers at my fingertips at the moment.  I suspect that the Hitron 4582 might be more tolerant, or, handle less than optimal signal levels better than the XB6, 7 or 8.  Don't quote me on that, just a thought at this point in time.  

 

If you had a two port (output) splitter you could use that to drop the downstream signal levels.  That will push up the upstream signal levels by 3.5 dB, which would still be ok as there is room until you hit the 52 dBmV limit.  A larger splitter would drop the downstream levels by 7 dB and push up the upstream levels by 7 dB, which would put the upstream levels into the failure point.  If the upstream levels were sitting in the normal 36 to 40 dBmV range, you could use a larger splitter, but, since their already high, that limits the manoeuvring room above their current levels and limits the size of the splitter that can be used.  That's where a Forward Path Attenuator comes into play, to drop the downstream signal levels and leave the upstream levels where they are.  Unfortunately, it looks like Rogers doesn't use Forward Path Attenuators.  One of these days I'll have to have a conversation with a Rogers tech to see what the exact policy is and what Rogers tech have on hand.  There has to be a better solution other than using a splitter to address situations like this.  Ultimately, the best solution is to address the cause of the high signal levels at the source, which is the neighbourhood node or possibly in a downstream amplifier.

It is the Arris.

From the hardward info panel in the admin gui:

 

TG4482A
Vendor:ARRIS Group, Inc.
Hardware Revision:10
 
I guess I will log a call with Rogers.
