Very frequent internet drops and slow speeds for over a week

Hi, 

I have very frequent drops in internet and slow speeds, this has been happening for a week. I use I a wired connection to device with wifi options off. Any help very much appreciated as the drops are enough that I disconnect from a work portal each time this happens.

    Looks like the Hub is getting the full speed for the 250Mb Tier?  Also your wired device looks to be limited to 10/100Mb connection?

    You will need to setup a BQM here  www.thinkbroadband.com/ping  Post a link to the shared graph for comment.  Thanks

      Hi Adduxi 

      I seem to have mark this as solved by accident! Anyway, yes Hub is getting the 250mb tier as expected but device is 100mb/10mb and sometimes less. Link to the BMQ I have set up here...

    For a wired connection to max at 93Mb/s indicates a 100Mb/s connection is limiting the speed.

    Connections often fallback to 100Mb/s due to a network cable fault, it may also result in service drops.

    Having same slowness issue today.  It seems there are some hubs are dead when I do a trace route.  Download speed drop below 0.1Mbps while upload speed seems normal.

    I have called the fault team but they said they don't see any problem. (Of course they didn't see it because the connection indeed is up, but just the speed is extremely slow.)

    Not all routers respond when running trace routes.  This is quite normal.  Get the BQM up and running and use the FULL tests on samknows for speed testing. Also post the power levels, Pre and PostRS errors and network log from the Hub

      I just signed up BQM, but the graph is still empty right now, I guess need to wait ?

       

      For samknows speed test, it doesn't recognize my router which most likely because it's not a consumer grade router, it is a commercial grade Netgate pfsense router.

        Okay, Samknows only works with the Hub in Router mode.  The samknows client is baked into the Hubs firmware.  Also VM will insist on the Hub being in Router mode as well for all their troubleshooting.  They do not support any 3rd party Routers, so you will be on your own troubleshooting pfsense. 

        How does a direct wired device perform when using the Hub as your Router with e.g. a laptop?

    When Downstream is poor make a call to 0800 561 0061 and see if there is a known fault in your street.

    Also check the Hub Upstream / Downstream connection stats are in the normal ranges.

    Do be open to examine all of your own kit, many many days have been wasted by folks that
    asserted their kit was perfect only later to find a faulty cable or whatever needed attention.

      It's a bit more complicated that you might think.  

      The download and upload speed is working fine on some sites while others are just painfully slow.  Both speedtest are done within 5 minutes.  One test site is Swish Fibre while the other is Zen Internet.  Both located in London.  As you can see one is extremely fast while the other is painfully slow.

      At least I can proved that there is nothing wrong within my LAN because I am able to reach very fast speed on some website.  That rule out there are issues within my LAN.

      From what i can see so far, I believe some hubs along the way from Virgin Media to some destination is having network issue.  If you happen not hitting those affected hubs alone the way, you will be fine.  If you hit those affected hubs alone the way to your destination, the download speed will be VERY bad.

        I was trying to do speedtest on Swish Fibre again.  Wireshark showed that the IP address of Swish Fibre is 31.22.12.17.  So I ran the following command on my PC 

      tcping64.exe -t 31.22.12.17 8080

      ** Pinging continuously. Press control-c to stop **

      Probing 31.22.12.17:8080/tcp - Port is open - time=26.723ms
      Probing 31.22.12.17:8080/tcp - Port is open - time=42.018ms
      Probing 31.22.12.17:8080/tcp - Port is open - time=25.073ms
      Probing 31.22.12.17:8080/tcp - Port is open - time=23.884ms
      Probing 31.22.12.17:8080/tcp - Port is open - time=23.858ms
      Probing 31.22.12.17:8080/tcp - Port is open - time=27.197ms
      Control-C

      Ping statistics for 31.22.12.17:8080
      6 probes sent.
      6 successful, 0 failed. (0.00% fail)
      Approximate trip times in milli-seconds:
      Minimum = 23.858ms, Maximum = 42.018ms, Average = 28.126ms

       

      The TCPing seems normal, but as you can see the download speed in speedtest is VERY bad tho

    try 

    ping -t -l 1472 31.22.12.17

    and run a speed test as ping is running and test with TCPing

      ping -t -l 1472 31.22.12.17

      Pinging 31.22.12.17 with 1472 bytes of data:
      Request timed out.
      Request timed out.
      Request timed out.
      Request timed out.
      Request timed out.

      runnnig speedtest while doing TCPing shows no difference in tcp ping time.

    One more thing, it seems the routing table did change somehow.  Doing the test to Swire fibre just now...the speed is back to normal and no longer have issue like you saw in previous post.

     

     

     

    However, other sites experience same issue

    not a good sign that VM DNS is showing packet loss...also ping is a bit high and TTL of 60 which would suggest you have two NAT routers?

    can you run

    tracert 194.168.4.100

    what about ping to VM WAN gateway your on?

      I have the VM engineer to come and check.  They have a tier two ticket.  Something wrong on the node out on the street.  However, it takes up to 5 days to resolve..............................

      As you can see in the screenshot, download speed is fine, but download speed is having problem on their diagnostics, which is matching my experience of the problem.

        I'm glad to see you are getting 2nd line support.   Hopefully they will be able to resolve it.
