Hi guys, great source of help and information, keep up the good work. Hopefully I will be able to contribute some day ^^ Problem: Intermittent connection to internet, happens every 5 to 20 min, none time specific, drops anywhere from 1 sec to 2 min. 2 xp machines hard wired to modem 2 feet away, win 7, 3 android, 2 ipad, 1 mac, wireless connected. All platforms drops at same time. Facts: Time Warner sent out techs to visit 4 times, replaced modem once, verified wiring good/solid, replaced underground wire from street box to house connector. Observation: During drop out, unable to ping, pathping, or tracert. modem show no disconnection of any sort, lights blazing as normal. tech support from isp says connection is solid.

Ping statistics for 24.28.199.168: Packets: Sent = 3539, Received = 3449, Lost = 90 (2% loss), Approximate round trip times in milli-seconds: Minimum = 74ms, Maximum = 412ms, Average = 85ms I believe the problem lie out side of my house, a line from upper connection possibly crossed or grounded with someone else. Question: Is it possible that I have a worm/software/malware/hardware that's crawling on my network, and preventing all my platforms from solid connection? Any input is highly appreciated, and thank you very much for the time you have spend reading and pondering this. Sincerely, James

Have you tried an alternate DNS ? Possibly OpenDNS

Just found out something interesting. I was downloading a few TV episodes on bitcomet just now, and the drop packets started, I was unable to browse the net, unable to ping as usual. However, the interruption did not effect bitcomet's download, as matter fact the download speed picked up more. So now I am guessing it is not ISP related or hardware related. Possible network type malware/worm is blocking ports on my home network. Any thoughts on the subject? I started a thread in virus forum already, hopefully they might recognize it better.

While we do not, by agreement with Forum TOU, assist with the use and funcionality of P2P/torrent applications, I can invite you to rid one or more of your machines from any installed torrent application, then turn-off or disconnect all remaining machines. Then, if you deem it important (particularly if you know that you have configured the router to open various ports), power-cycle your modem and router, or better, completely reset both router and modem to factory default (tedius perhaps but useful) and then run with the one or more machines that have been cleared of bit-torrent. If your observation and hypothesis is correct, these freshly cleansed machines and network components will function properly and will not demonstrate the packet-drop phenomenon. If the above experiment proves out the result, then you have your answer. If not, then one or more of your machines may in fact be infected with unwanted software that was not removed by uninstall of torrent application and you would then be well advised to use the services of our excellent Malware Removal forums.

I fully appreciate about not supporting torrent, but that was not the subject I was asking, it's was a simple observation. Anyway, thx for the time and input. I have figured out the problem area. Turns out to be that my Motorola Surfboard cable modem was the bad connection. For some reason, the firewall on it will drop/block packets at will. solution was to set it to bridge mode, and use my own dd-wrt router. Hopefully this might help someone else out there, and I know there is a lot of them ^^ good luck.
