[HSI] Outbound speed issues and packet loss(WA)

I live in Yakima and noticed some issues that cleared up yesterday around 7pm in a short manner. Today the problem came on around the same time, I noticed my upload speed was 1/8th or less of what it should be. Not sure if it is due to what ever problem that is causing this but I've noticed packet loss along all of charters network starting with the jump beyond my modem any where from 10% loss to 40%.

When the problem is happening, perform a tracert to whatever the destination is that you noted.

It's more along the liens of being continuous it hasn't cleared up, I've used pingplotter going off of a few different sites and all have had the same general packet loss. It's not always exactly the same each time it traces, at times it might be 10% off of one jump at times it's everything. Upload speeds are still the same as when I posted before.

Is your cable modem bridged to your router?

I would still prefer to see a tracert to any of the sites you listed. I'm not all that familiar with ping plotter and how it displays it's results.

However, based solely on the one plot you provided and depending on your answer to my question above, it looks like the initial packet loss is from your routers want port (if the modem is bridged) or from the modem itself if not bridged.

Just as an example, here is a tracert from me to twitter

over a maximum of 30 hops:

Also, if you're interested, you could use one of the several different ping/trace tools available from the DSLR website, found under the »/tools TAB.

This is an example of the line quality/ping test on this site. I just ran a test to my PC by way of example. In my test results, my first hop shows 100% packet loss results. This was do to my router being set to not respond to ping (ICMP) packets.

The issue seems to have cleared up, I'm also seeing normal upload speeds. The issue wasn't from my router, after that screenshot I connected my system directly to my modem and still had the same problem power cycling the modem didn't help. Hopefully I won't have this problem again, if so I'll post a tracert. Most of the time last night using this program I'd see issues that were a few hops beyond what you see in the screenshot.

Right on queue it started acting up nearly the same time as it did yesterday, it seems to be intermittent packet loss. Every few seconds it spikes to an extreme then somewhat clears up. I've tried running a tracert but the problem doesn't persist long enough between it's intermittent cycles to complete it.

Running pingplotter shows the same thing but shows the packet loss percentage spiking into the 70s to higher. I ran a line quality test while typing this message and this is what I saw.

Were you using your router for the ping plotter test?

What model cable modem do you have?

Based on the ping plotter test, the only packet losses occur at your home network, ie; modem and or router. There is no packet loss anywhere else along the path from the 2 locations and with the various bit rates.

SB6120 modem with a wired connection off of a WRT160N it's not the router since I've connected directly to the modem and the problem still persists. I'm finding it hard to believe that it would be anything on my end since it happened two nights in a row at nearly the same time. My internet was perfectly fine the next morning but once it hit that time it started again. I'm wondering if something along the connection before it hits the house was damaged or messed with by someone but I'm finding it odd how it only happens during a period. I see my upload is having speed issues so what ever is wrong it's effecting that more than likely pack loss on the upstream.

Here is the signal stats off of my modem.

Well...do to the timing (time of day) of this issue, it's going to be HARD to get Charter to actually look into it for any real troubleshooting. However, based on what we've seen in the ping/plotter results, I'm fairly certain the issue is at your premises and not on the network outside your home, there's just no way that I know of, on how to prove it one way or another. Is your SB6120 modem provided by Charter or is it yours?

If it is provided by Charter, go to your local Charter office and get another one. If its your modem, see if you can arrange a temp. swap with a local neighbor.

Is there anything in your home environment of an electrical or RF nature that might be active around the same time of these incidences?

Are there any additional cable splitters up/down stream of the coax connected to the modem?

Make sure any additional coax terminations are screwed on tight and that all of the actual connectors have no frayed or bare shielding between the barrel and the insulation wrapping.

The SB6120 is my own modem, use to have a modem from charter a few years ago but that was when they charged to rent them. Had that modem for over 10 years and needed to replace it, so I bought it to drop the extra 5 dollar charge but this was 3 or so years ago. As far as the line condition, way back when the line was put in this would have been before charter took over our area the line is a fairly sturdy thick cable. There are no splitters that run off of this cable on my premises, on the land there is a box which the cable goes to which I would assume anyone within general area connects to as well. Somewhat threw out it might have being messed with at the box end of the connection either by an installer or someone tampering with it since I noticed that the box doesn't close or lock properly.

If I have an issue with it again tonight I'll shoot charter a call, though it being Saturday in the evening not sure what kind of response I'll get. I just find it so strange it's a time of day problem it starts around 7pm and I think clears up between 7 to 10 am the next day. Also only causing problems on the upstream channel.

Do you have any "close by" neighbors that also use Charter internet? If so, maybe check with them to see if they experience the same issues. Also, this box/pedestal thats outside, where your home cable run connects to, how is your piece of the cable run connected inside that box?

For the part of the cable that's above the ground is fine, can't be certain about whats underground obviously. Not really sociable enough with my neighbors to even know if they have Charter for internet. I might have been a bit quick to state the internet returns to being perfect during the day, it might be that the problem is less severe. I ran a line quality test when it seemed the issue clears up and it's showing a 2% loss on one of the connections that run the line quality test on the last hop to my connection Test 1 Test 2. Tough it's not as bad as it is when it hits that time of day when it starts doing this and this I would assume if it's working the way it should I should expect no loss at all.
