    Random Packet Loss

    I have my theories, but I want input on it.

    I have a D-Link router/wireless AP that's about 2 years old. Ever since I got into my new house, I can be on my computer running ping tests and I will start seeing timeouts ever 10 - 15 packets. Sometimes it doubles up.

    I factory reset everything, and did not restore my settings to it (I have port forwarding), I did everything fresh.

    Worked great for about 2 weeks, now I am dropping packets again.

    Thoughts?

    Charter has been out here half a dozen times, fixed the cable from the main distribution box to my house (cracked insulation) and that fixed it for about a month. I can go directly from my cable modem to my laptop with no ping drops...when my cable modem is up and working ( I am now on my sixth modem)

    I was under the impression that the majority of packet losses stems from faulty cables. Did you make your own cables for inside the house? Are the cables outside the house done properly, with good tie downs to keep them from breaking contact in the wind? Does it happen more often when it's wet outside?

      Actually all during the recent super storms and during the snow storm it was find and dandy. It started happening in the dry...weird I know.

      The cable is a pre-made 50 foot cable I just strung along my floor. I haven't wired my house up yet (though I need to do it before Spring gets here)

        You're dropping when wired or wireless or both?
        How do we forget ourselves? How do we forget our minds?

              luckily it's random packet loss and not specific packet loss. Those are the ones you have to worry about!

                It's just the ones the Govt. are plucking out so they can find where I hide my pr0n.


                And it's wired packet loss.

                And when I mean random, it's not like it's every 5 or 10 packets. It will be the 9th then the 13th then the 11th and 12th...If it was a TX/RX failure say at the hardware layer, it should resemble some pattern right?

                  Electronic component failure rarely has a pattern to it, aside from higher current applications when the component has reached a threshold.

                    Set your local NIC interface to 100/FULL , make sure no auto-negotiate.
                    Do the switch side to if you can.

                    If that doesnt help

                    Try different cable.
                    Try another NIC or computer.
                    Update firmware on Router and/or Network card.

                      Well I haven't done anything at all and packet loss is gone. I guess Charter was doing some line work or something. Pisses me off, I have the worst QC from them.

                      I'll try those steps in the future, appreciate the suggestions.

                        Whats your target?

                        If its the gateway or another device (printer, dvr, etc), and still dropping you have a local cable/switch issue.

                        If its an external IP, don't go all the way out to 4.2.2.2 or 8.8.8.8.

                        Start with your gateway, then the Isp gateway/dns and then go out further.

                        As soon as you see packet loss, stop.

                        Edit- now saw your last post.
