Getting packet loss on only one computer on the same network

  1. Hello,

    I am having issues with my internet. When I do a test on pingtest.net I get 4%-90% packet loss but when I do the same test on other computers in my house they get 0%.

    As I'm a gamer this is a huge issue because I experience exactly (I have experienced EVERYTHING in this description)

    "Much as it sounds, if you have anything less than complete success in transmitting and receiving "packets" of data then you are experiencing this problem with your Internet connection. It can mean much slower download and upload speeds, poor quality VoIP audio, pauses with streaming media and what seems like time warping in games -- your connection may even come to a total standstill! Packet loss is a metric where anything greater than 0% should cause concern."

    (from pingtest.net)

    Here are my netlyzr results:
    http://n2.netalyzr.icsi.berkeley.edu/summary/id=43ca208a-2675-3feb3837-18cc-4d34-9c63

    What ive tried thus far and didnt work:
    • Malware scan
    • Uninstalling firewall
    • uninstalling antivirus
    • I have used wired and wireless connections and still getting the same problem
    • FULL scan for viruses etc
    • used win 7 troubleshooter-doesn't have a clue
    I will admit I have torrented before (I have stopped now) and I used to get 500kbps down on bittorrent then I think plusnet(my ISP) somehow caught on and stopped it then I got 0.4 kbps...
    Maybe something to do with that has caused the issue.

    I still have Microsoft security essentials on my PC, if that might be causing trouble.

    If you need more info please ask.

    thanks

    Describe the network hardware (make/model how old) and your connections to it. I've seen ethernet slots on routers go bad, so swap the cable from one slot to another.

    Get a command prompt and enter this into it
    pathping google.com >google_path.txt
    it will take a few minutes to complete
    attach google_path.txt to your reply OR copy/paste the contents of it

    Actually, there's some info there.

    First issue is 1% loss getting from your PC to the router at 192.168.1.254 NOT GOOD :'(
    Try the same pathping using any other pc. If they all have losses from PCs to the Router, then replace the router. Otherwise, look for new firmware for the PC ethernet driver on the failing PC.

    Nodes 7 & 8 stink too but nothing you can do there. You did manage to reach google at 173.194.41.71 however. :)

    Okay so I tried Ethernet again and im getting 0 packet loss, it was my WiFi dongle, or the USB connecting it to the computer. However im getting still getting fluctuating ping. this may be due to the very long extension cable running to the router. We are going to replace the setup we have with a all Ethernet setup now so that there's no extension cable because who knows how much that old, outdated long extension cable is causing...

    Thanks for your help. Ill do another pingpath just in case.

    Is this better? I have 0% packet loss on pingtest.net now

    Much better & extension cables are usually problems at the connectors!

    jobeard TS Ambassador Posts: 9,023   +590

    Btw: you DO know that the limit end-to-end distance for a single ethernet cable is 100m (300ft). If you need more than than, insert a dumb switch as the junction box :)

    Yeah I did thanks, I learned form computing in school, they need fibre because its over 100m. They have those boxes too

    Hi Jobeard im one of benedrix's friends who linked me to this article, I have suggested to a lot of my friends including benedrix to use the test socket behind the main BT faceplate on the phone socket permanently to help cut out interference from any extension wiring that could be wired into the back of the faceplate, is this a good way of making sure we're getting max speed and reliability on our ADSL? or is there any problems with doing this before I recommend more people to do this?

    Hmm; you can - - but I doubt there will be any discernible effects.

    the setup like
    -/-/->phone.line--ADSL.modem--direct.PC.connection​
    would be sufficient to test the Line, Modem & the PC nic

    I dont understand that diagram :/. I have the new setup and it hasnt made any difference. Im still having issues on league of legends with ping:

    http://euw.leagueoflegends.com/board/showthread.php?t=1251919 (im benedrix)

    Also my dad, and on my ipod get 4mb/s on a speedtest but for some unknown reason I get less (0.6-1.5).why is this? (im still on wired btw and so is my dad)

    We found out we have ADSL1 and are requesting to upgrade.

    My friend(georgepen) just down the road from me gets 16mb/s so I dont understand why mine isn't the same/similar. Do you think he has better line quality? Or is it because I his ISP is better?

    That diagram would allow you to get max download speed. It does require you to trace the line that comes into your dwelling then you tap into that line and then run your feed to your ADSL modem. You'll need connection boxes shown in the diagram. Use Cat5 Ethernet cables or ultra phone line cables.

    Hi everyone
    Well I seem to be having a similar issue. I have 2 PC, storage drive and printer connected onto a Fritz router. All are connect with Ethernet cable. However since about a week have been having issues on my gaming PC. I have check with my provider who did a check of my line and found no issue. I ran the same check as mentioned in this topic.

    I have checked with a second router, swapped the Ethernet cable, check for new drivers for the motherboard.

    the wiring from your PC to the router STINKS - - replace it. Run the test again after the change and you must get 0/100 = 0% and if not,
    1. the router slot is defective (move the connection to a different slot)
    2. or the PC NIC is bad (look for a driver update)

    Thanks Jobeard

    I have already replaced the Ethernet cable and swapped the port on the router. I guess it is my Ethernet on my PC motherboard. I have check the internet and my current driver is the correct on (so windows tells me).
    Thanks Jobeard

    I have replaced the cable and swapped the port on the new router with the one which has a PC connected with not network issues. Still package loss. I have reinstaleld the driver even through the latest was already installed. So guess next step is to go out and buy a PCI Ethernet card. On board was a Intel 82579V gigabit network connection, motherboard is a Asus P9X79. If that helps.

    Nodes (1) & (2) are your equipment and wiring

    Hello,

    Recently I have been having an issue with packet lose on my PC. I just came home from school for the holidays and hard-lined my computer to the router. The problem is the random lag spikes in games. I can play a match and have no ping issues, next game and I will get "reconnecting" issues and my screen has extreme lag for about 10 seconds. While im back at school, I never have this issue. As well, there are 3 other computers hooked up to this router and mine is the only one having this connection issue. I tried running the pathping google.com >google_path.txt in a command prompt but nothing was happening.
