    Exclamation ping spikes

    Hi there,

    I'm hoping someone can point me in the right direction with these ping spikes I've been having. I'm with a business high speed company in Canada (Bell). The bandwidth usage is unlimited and they say they aren't doing anything to curb P2P traffic.

    My ping at speedtest.net is a nice 18 ms usually. In an online game an average ping is 40 something. But after 5-10 minutes it will jump to the 700s and beyond. This will last for a few minutes, though exiting the game (and why not...I get a ping kick) helps it return to normal faster (~30 seconds instead of ~1-2 minutes). This happens with streaming video as well, though perhaps less often (which may have more to do with bandwidth demand). It seems to start up after 10-15 minutes and will return to normal as quickly as with the game if I pause the video. The spikes happen when surfing too, I just can't tell if the frequency is different since I'm not constantly using bandwidth as with the game or a video.

    Things I've tried:

    -new router (linksys E3000)
    -updated router firmware
    -changed MTU and channels
    -new cable between modem and router
    -new modem
    -windows 7 (64 bit) tweaks
    -updated all drivers (tried disabling sound)
    -The spikes happen to me (PC, wired through router) and the wirelessly connected laptop (mac), even if there's only one computer on.

    Things that are weird:
    -I call my ISP and say test the line I'm having a ping spike, and they say the line is fine. (Maybe they just don't catch it in time? But that just never seems to be the case).
    -The same thing was happening with the old router; I don't have a static IP nor have I played with the default settings other than the MTU and channel.
    -If I take the router off and wire directly from the modem, the ping spikes sometimes happen less often, maybe once every 1-2 hours. I don't do this often, so maybe it's been just a fluke that that has happened a couple of times.

    To me the problem must be in the line. Could there be a problem that the ISP wouldn't pick up? Something in the house? Something about electrical supply? My surge protector says that there's a building wire fault in all the outlets upstairs, but our building inspector tested them and didn't seem alarmed. Maybe they aren't grounded or something, I forget.

    This is driving me batty. If anyone has any ideas I would be more than grateful.

    Thanks!

    First, make sure you do not set any torrent program to load on Windows startup, and also, set a global upload speed limit into the torrent program to about 60% of what your ISP gives you.

    Do two tracerts and post, one with the router and one direct connect through the modem.

    Thanks so much for your help. Here is a traceroute I just did with the router. I was experiencing no real slow down of the connection:

    I was trying to get a ping spike without the router and it's been 30 minutes without one. My experience in the past is that it doesn't spike for 1-2 hours without the router. It seems strange that the old router and the new router would have the same performance issue if it's the router. I thought perhaps it was aggravating a pre-existing condition, but I can't imagine how that could be so. I did a traceroute when it was spiking (with the router) a few days ago. I'll post it here:

    Problem is not at your end, but in signal routes through the intermediate routers of atlas.cogentco.com

    Some other gamers are also reporting this problem:

    It is usually cogentco, but I really can't explain why taking the router off reduces the problem so much. Any ideas?

    When I talk to the ISP, this little tidbit of information makes them tune out. Last night the tech support guy told me the problem was with the game host and to talk to them when I get a ping spike. When I reminded him that it happens streaming video at various sites and even just surfing, he just repeated it. So I said thanks, I will contact the world wide web when I had a ping spike, see what they can do about it. Very helpful.

    Could be the router is emitting electrical interference and affecting the modem. Problem can be solved by relocating the modem a few feet away from the router. In fact, the modem should be kept away from ALL other electrical devices. I place mine on the floor under the comp table.
