Re: Rogers packetloss


said by HiVolt:

What drives me nuts about my particular issue, is that it's completely random, completely unpredictable, and can go for days without issue, then strike with a vengeance for 4-5 hours sometimes twice in a day.

Imagine how our maintenance techs feel.
They are watching to see it happen from outside your place.
They need it to be happening in order to track where it's coming from.
They could spend all day waiting for it to happen, and it doesn't.

Or worse, they tweak something at the same time the customer causing the noise turns off what is causing it.

They think they fixed it.

Rogers can't be forthcoming about problems they aren't aware of.

Rogers had 6 open tickets in our complex for the same noise problem I was generating TPIA tickets for (that was virtually identical to hivolt's problem), and Rogers closed our tickets with 'no problem found everything in spec' for weeks.

When I said "not forthcoming" I was being polite in someone else's thread. Is all.

Mine's been much better, only a few periods of much less packetloss (registers as blue in smokeping rather than purple/red).

Maybe they've done something, though they didn't quite find all of the noise/interference...

Experienced this around 20-30 minutes ago, lasted around 5 minutes. This has been happening to me every day for the last week.

I've noticed it happen twice a day consistently.

Everyday around 3 PM , it will last for 5-10 minutes.
And around 30 minutes after mid night.

I live in Downtown Toronto

Since July 2, we upgraded our business service with Rogers to their new static IP 150x10mbps package and received a new modem, we've had the same issues. Random packet loss at least once or twice a day but can be bad enough that our internet is intermittent and unusable for hours. Being a business requiring 100% uptime for our VPN, Citrix and other hosted services, this packet loss is definitely unacceptable. We've had 3 rogers techs come in to troubleshoot to no avail. Even Rogers phone support confirmed 56% packet loss on one occasion. Just letting everyone know we are in the same boat as you. We're in North York, Finch/Dufferin area.

Mine's been working fairly well recently, looks like they fixed the issues in this area...

Now if they only did it the first time they detected the packetloss and didn't send the the contract techs who just want to replace lines/connectors because they get paid extra for them, it would have been peachy.

Same packet loss issue here just like Mash posted above, Steeles/Dufferin area has been going on a month now, techs replaced lines and new modem and no fix so its an internal Rogers issue. They need to get this nonsense sorted.

What's the best way to tell if I have packet loss? What program should I run? Last night I had connectivity issues and I was trying to ping www.rogers.com and I was getting lots of failed pings. This has happened a few other times in the last week, primarily during prime time. I am in Scarberia near Markham and Kingston.

HiVolt uses PingPlotter. I use a simpler tool called PingInfoView which you can download at »www.nirsoft.net/utils/multiple_p···ool.html . I ping a few common sites like google and rogers and also my router's gateway address. It gives me an idea if there is packet loss but won't show the route packets travel.

When things were bad packet loss would get as high as 20-50%. When things are good it is 0%.

Thanks - so this really isn't much more than running "ping www.google.com -t" except you get better stats and a better UI.

Ok so tonight between 8:17 and 9:57 I received lots of ping failures according to PingInfoView. I started running the program it at 5:33 and was rock solid until 8:17 and it has been solid again for the last 47 minutes. I see lots of red lines on PingPlotter that correlate to this as well.




Is this indicative of Packet Loss?

It looks like I also had a lot of packet loss between 3am and 9am this morning. Does Rogers use Sunday mornings at this time as a maintenance window?

Can you post in the DOCSIS WAN downstream and upstream tables from your modem. I don't need to see the IP address and other data, just the tables themselves. I'm wondering if the issue with packet loss is in any way associated with problems with Signal power and Signal to Noise ratios.

@99.224.154.x
Your Downstream Signal strength is too low and your Upstream is too high. The Downstream target is 0 dBmV, while the upstream should be around 37 to 40 dBmV. My guess is that your downstream signal power is on the edge, and for some reason, its probably dropping during the periods where you see packet losses. You probably have a cable or connector problem between the external connection point and the splitter which is used if you have more than one service, such as tv or home phone. The external cables and connectors don't last forever and require replacement when they start to fail. Unfortunately, they don't just fail completely, which would make the problem much easier to diagnose. Usually they start to fail intermittently, which causes nothing but frustration. Best thing to do is call in to tech support to arrange for a visit from a field tech. Tech support should recognize the signal power issue if they look at it. If you get any dropouts on anything, computer, tv, or phone, call tech support. Put them on speed dial.

What service plan are you on, and what is your typical result for a speedtest. Just wondering if you are connecting the CGN3 to anything with 10/100 Mb/s ports which causes the CGN3 to throttle back the download rate due to a bug within the firmware.

I have the Ultimate 250/20 1TB service. The only thing connected to the Ethernet ports of my CGN-3 Gateway is my Asus RT-N66U router (which has gigabit switching) which then connects into a 24 port gigabit switch. The Gateway is in Bridge mode.

In terms of cable connections the cable comes into the house from outside goes through a 1x2 splitter (which is from Rogers) and one output goes to the Gateway. The other output goes to a 4 way powered distribution amp (also from Rogers) that drives three cable STBs as part of my HTPC SageTV whole home PVR solution. But does it matter what is downstream from the first splitter? I have used this setup for about 7 years although my modem/gateways have changed a few times. The cable splitter/amp setup has been constant.

My internet has been pretty solid since the CGN-3 firmware issue was fixed several months back.

How can I have such different signal strengths on upstream vs downstream? Doesn't the cable follow the same path?


Datalink

@99.224.154.x
Ok, it looks like you have gigabit service throughout your home. With that, you should be seeing peak downloads of 325 Mb/s and 20 to 21 Mb/s up at each wall connection port. That is of course if the house ethernet wiring and connectors are set to support gigabit connections. If not, you will only see 100 Mb/s max at those particular wall ports. Can you tell me what you get for download speedtest results at the wall ports, if you have checked them out of course...

If you are not seeing dropouts on your tv service that is probably due to the distribution amp.

The difference in the signal strengths is due to the measurement point. Remember that the downstream measurement is the final measuring point which happens to be at your modem, after the signal originates from the local neighborhood node, travels down to the local cable box near your house, and finally through your external cable, the splitter and to the modem. All cables have a known electrical resistance per foot which results in final decreased signal levels at the far end of the cable. I don't know what the original output level is at the node. Maybe its as high as 35 to 40 dBmV. But, after all of the cable and splitter losses getting to your modem, the final level should ideally be around 0 dBmV. As for the upstream side, you are seeing the output level at the source, instead of the final end point. I suspect that it is high due to a failing cable or connector, so you might be getting feedback from that point back to the modem, which is pushing up the output measurement.

Maybe during peak usage times there is increased demand on the local node which is causing a minor drop in the voltage levels in the neighborhood. At 0 dBmV, that might not be a problem, but at -9.1 dBmV, which is your worst case channel, that minor drop might just be enough to cause problems.

Hope this helps

Right now I am getting speedtest.net results of 235/20 on my client - but there are some other family members using the internet. Occasionally I get the 320ish download speeds, especially if I connect directly to the Gateway, but normally I get 250ish download speeds once I go through my router.


Datalink

@99.224.154.x
320 Mb/s is good. That should be a normal max speedtest download rate when the signal levels are back at 0 dBmV. 250 through the router would probably depend on what monitoring functions you have enabled within the router itself. It might also depend on the cabling that connects the modem to the router, and then to the switch. If that is all connected with short, commercially produced cables, then I would say it’s simply a matter of how much the router is expected to do. Not so long ago I was chatting with someone using Merlin firmware on an Asus router. Turns out that download rates above 100 Mb/s are possible, but not when certain LAN monitoring functions are enabled within the Merlin firmware, which in turn disables the high throughput capability on that router. So, something to keep in mind is how much the router is expected to do, above and beyond simple signal distribution.

The other consideration is the condition of the house Ethernet and its connectors. If it’s all Cat 5e / 6 and all of the connectors use all 4 wire pairs within the cable, then in theory, you should see 1 gigabit capability, end point to end point. If you have a laptop handy which can accept 320 Mb/s download rates or above very easily, you can test your distribution system, connection by connection, starting with the gateway, and working your way down to the switch and then out to the rooms. Depending on the monitoring functions enabled within the router, I would expect you to see 320ish download rates throughout the house. For the switch itself, if it has indicator LEDs for 10/100 Mb/s connections and another LED colour for gigabit connections, you can see very easily which circuits have any issues and are not using all 4 wirepairs to run a gigabit connection. That will also depend on the device that the switch port is connected to, which at the far end, just might have a 10/100 Mb/s port. So, you would have to know which device has a 10/100 Mb/s port and which has gigabit port in order to correctly interpret the LED display on the switch. And then, the switch itself has a finite switching capability. If you look at various switch specs, you will see that they have different maximum switching capabilities, or throughput.

If you had any doubts about the ethernet cabling / connections you could buy a LAN tester to determine if the cabling and connectors are connected properly end point to end point. Here are a couple of examples you could use:

Much better tonight - one bad stretch from 9:00-9:30.

I run Merlin on my router. I know that I have, at times, seen 320 Mbps from the router but most time it peaks out at around 250. When I have tested this in the past it seems like directly after a router reboot I would get the 320 speeds but after 15 mins or so it would go down to 250. But this may have been before I started using Merlin. As long as it doesn't indicate a problem I don't really care as there really is no practical advantage between 320 and 250 since you never sustain speeds anywhere near that speed over the internet. Plus the 320 is the temporary speedboost. My cables are generally from Monoprice but some are the cables that come with devices that you buy like routers, IP cams, etc.

My wiring is all CAT-6 so that should be fine.

I have a LOT of devices on my LAN, although not always at the same time. The last time I did an inventory I think I was at about 65 devices that use IPs, not including switches with no IPs - I have a lot of Home Automation stuff, IP cams, etc.
