Consistently INCONSISTENT Internet Connectivity / Latency

We moved into this house 6 weeks ago, and 5 technicians and 3 brand new modem / router combos later, my internet connectivity / latency is still horrible. I am directly connected to my modem, and I can barely use my internet.

 

Every time someone from TWC comes out, they check the lines and apparently everything is "working as it should", yet I still have extremely high latency to the point of unusable internet. This is even happening during the night (midnight - 6am) when there is no internet activity.

- All of my devices are experiencing slow internet latency (iPhone, iPad, SmartTV, 3 computers). Even when only one device is connected, I am having the same issues. 

 

- I have tried using 3 different modems (All DOCSIS 3.0, and 300Mbps +)

- I have tried using 5 different ethernet cables (combinations of cat5, cat6)

- I am restarting my modem/router several times a day because it will temporarily (for about an hour) lower the ping and stretch out the times between time outs and extremely high latency.

 

Below are some ping results (very odd how consistently inconsistent they are). These results were taken during the night, when there is no activity (no computer updates, watching Netflix, nothing). NetGear information is posted below this as well.

Re: Consistently INCONSISTENT Internet Connectivity / Latency

no modem logs or error count data?

Re: Consistently INCONSISTENT Internet Connectivity / Latency

Obviously not.... Not sure exactly what to post here... I"m a bit new to troubleshooting this, would you have any instructions on how to obtain that info. I just posted some info I have seen other users send.

Re: Consistently INCONSISTENT Internet Connectivity / Latency

Are you internet only? DS level is low, indicates a splitter or two in line....

 do a plain cmd level tracert to google.com, need to see all the hops

How many devices are connected and why are you using an obsolete 8 ch modem?

 what model is it?

 Are any devices running cloud or sync?

I doubt you're unplugging the smart TV, it is indeed connected when turned off, same as with other devices.

 What speed are you paying for?

Re: Consistently INCONSISTENT Internet Connectivity / Latency

How about:  Why does your modem have a temporary bootfile?

See that funky looking jumble of letters and numbers?  That's a temp file, kind of like your modem's last known good configuration.  Billing service codes need to be checked, might not be current codes for 2016.  Or maybe they are and your modem just needs a "hit" to update it.  You never told us what speeds you've got setup in billing.

 

And no, downstream/Rx levels are not too low.  Tx seems to be fine, at least what you shared.

 

WIthout a list of error log messages (including MAC's) I can't even comment on ingress properly, but that's a possibility too (and I don't just mean in your home, it could be a neighbor with such bad ingress (i.e.: when they turn on some junky equipment they have connected it's so extreme that it even causes you internet issues).

 

I'm frankly not even clear if this is a netgear gateway modem (modem + router combined) or two separate devices.  The community here would be more helpful in giving advice if we understood more about your LAN topology (what connects to what, model #'s and such too).

Take a look at this ol' topic another community member made, it's quite thorough.

Re: Consistently INCONSISTENT Internet Connectivity / Latency

Correct, internet only. No splitter as far as I'm aware of. We have about 4 devices connected (depending on if our phones are on WiFi - Home Computer, Laptop, Work Laptop, TV). 

 

I wasn't aware my modem is considered obselete. It is a NetGear N450 Model No: CG3000Dv2. It is on the approved list for TWC and was one of the ones mentioned when I was on the phone with support. 

 

I am not running any cloud or sync on my devices (occassional Windows update should be all). 

No, we are generally not unplugging the TV, or any other devices as there is no difference (from what I can tell) . I can have only one computer plugged in (I tested this a few weeks ago) and still very unreliable speeds. I would be happy to try again if there may be some improvement to my speeds / connection somehow.

 

Paying for Standard (15 / 1). 

 

Tracer T is below. Keep in mind that it is "earlier" in the day, and my pings "reset" earlier in the morning, meaning that the longer the day goes on, generally, the higher my pings go (whether we are doing something, or away for the weekend with no activity). The timeouts about every 10 seconds on my original post now only have pings of approximately 500-1k. Later this evening, they will begin timing out after they hit about 3,500+. 

 

I cannot attach a graph, however, a text display below is of our average pings per hour while we were away a few weekends ago. Once graphed, you can see the pings continually climb and get higher, then go lower, and climb again. This pattern repeats daily.

Re: Consistently INCONSISTENT Internet Connectivity / Latency

Thank you for the info on what to post. Please see below. I am happy to provide more information or clarification if need be. 

 

Main issues are computers and phones (computers are directly connected - except the Mac)

- Home (Windows 10)

- Work (Laptop - Windows 8)

- Home (Laptop - Mac)

 

  1. Your location. city, state, zip. Single or multi family complex.
    1. Twinsburg, OH / Single Family Home
  2. Services you get from TWC
    1. Internet Only (standard)
  3. Make and model of modem
    1. Combo: NetGear N450 Model No: CG3000Dv2
  4. Make and model of router(s)
    1. See above
  5. Firmware level in modem (or, post modem page)
    1. Firmware Version V3.01.06 (not sure if this is what you are looking for). 
  6. Confirm modem is Online or report otherwise. Login to your twc account and click on troubleshoot. Confirm modem with correct serial/mac has a green dot. See this example. (mac/serial masked out in this image)
    1. Modem is connected. Mac and Serial # confirmed.
  7. What are your purchased speeds? What are results from TWC speed test. down, up, ping, jitter?
    1. 15 / 1 (standard speed)
  8. List symptoms using a wired (not wireless) connection with date and time and any repeating pattern
    1. high pings every 10 seconds (anywhere from 500ms to 3500+). If these 10 second pings are not occurring, I am consistently over 500ms for almost every ping each second.
  9. Modem's signal, downstream and upstream, and event log pages. usually accessed at 192.168.100.1 or 192.168.0.1
    1. posted in a response below. 
  10. Description of your cable wiring from street and throughout house, include splitters, devices, cable type (rg6, rg59) and age, etc. and specifically the where the modem attaches.
    1. Wire from Street to outside of house > Outside of house to inside of house > inside of house directly to modem.
  11. Description of ethernet network from modem’s ethernet port to router(s) and to any additional devices including cable type, e.g., cat5, cat5e, cat6, etc.
    1. Main issues are computers connected directly (have cat5, cat5e, and cat6 cables)
  12. Any recent or coincident changes or upgrades to your system, or any neighborhood changes.
    1. Recently moved 6 weeks ago (had similiar issues at our apartment before moving, but it is much worse now)
  13. Run pathping (windows command) targeting a site that demonstrates problem, preferably one that is pingable, like rr.com. If pathping is not available as command execute tracert. (Linux command istraceroute)
    1. TracerT posted in a response below
  14. Mention if you only have connection problems while streaming movies/other or playing games.
    1. Streaming movies is actually okay oddly enough (the picutre is fuzzy, but does not stop and buffer very often, maybe 2-3 times per hour show).
    2. Games are impossible to play (with 500+ pings every 10 seconds, there are not many games that would not affect).
  15. Are any background tasks running that upload or download data automatically, e.g., backup programs, torrent client, file/photo/music sync, auto program/app update, etc.?
    1. I have turned off any automatic updates. There is no torrents, cloud, or syncing occurring.

----- END Modem Error Log -----

 

I'm pretty concerned looking at that error log (without further investigation or clarification from someone, I am not certain what all those errors mean), however, this is our 3rd DOCSIS 3.0, Wireless N modem in as many weeks and they have all experienced the same issues regarding my post subject.

19 hops to Google? Yeah talk about great routing.

Re: Consistently INCONSISTENT Internet Connectivity / Latency

Copy and paste a cmd level tracert to google.com.

 Are you in a new or an old development and is wiring underground? how far from the pole?

Signal level is low for no splitters, can you follow the line from the grounding block to the modem? Are there  wall jacks in other rooms? There are some really bad, 40 year old cables and amps still in use in the area, lotsa bad connections.

 the other issue is that the 699mHz and up channels aere subject to 4G lte ingress, Verizon has a bunch of pole top 4G sites like this one, however they're up at 741 mHz and up.

 luckily, we're only seeing 12 DS bonded channels, however has 7 more above the ones in use that are badly interfered with.

 

The 8 ch modems are obsolete as they can only handle a span of 16 channels and in many areas (not here yet) 24-32 channels.

I can follow the line, it is new as of 6 weeks ago. No jacks in other rooms. 

 

Older development, wiring is underground (where it connects from the street). All new wiring > Street > Outside of house > Inside House. 

 

Any recommendations on modems? I have been using 8 channel for a while now (looking back on all my old ones) and haven't had any issues before... but I guess they have to get obselete at some point =)
