    Alright, so lately I've been having terrible ping spikes while trying to play games... I have an image here that shows what I mean:

    [​IMG]

    Here is another, it's the same run just for a bit longer:
    [​IMG]

    The first one is my router, the second one is my modem, and I *think* my third one is my dish (I have some wireless internet, and before you say that's the problem - it's not. This is a newly developed problem and it has been good before.)

    The most common one to read higher than usual is the second one (see the avg column).

    I'm not sure how ping is read, but it is either the modem or the dish depending on how this works... It shouldn't take on average ~60ms to get from my modem to the dish.

    looks like a peering issue with your ISP to the backbone providers. something on your ISP's end not yours.

    How come the ping jumps so much with the connection between the modem and the dish then? To me that looks like a local problem since it jumps before it leaves my house. (sorry if you answered that, but I don't know what peering issues to the backbone servers means :p )

    Ah, I was looking at the next one down. how far is the wireless from you antenna to the one on the other end? you are seeing an issue on that link. as well as the one were your ISP gets their bandwidth from.

    I'm fairly certain it isn't a distance thing since nothing was moved or changed, then all of a sudden this started happening one day (3 months ago?) and it wont go away. It doesn't happen constantly this bad though, it's very inconsistant. The parts don't have that much wire connecting them either (it's less than the max distance for the type of wire - I can't recall the name right now though...). Unless you mean how far am I away from the tower? If so, then I'm really close - only like 3 miles away. I can pretty much point the dish any direction I want and I'll have a nice signal :p

    My ISP isn't that great in the first place, but I could get a constant 80ms ping to a bunch of servers that I like before this happened. It is the best internet I can get where I live so sadly upgrading isn't an option. :(

    I don't think it's the ISP at all actually since the ping jumps between Hop2 (modem) and Hop3 (dish) most frequently. It does happen between Hop1 (my router) and Hop2 (modem) occasionally, so I personally think it is Hop2 (modem) that is causing the problems.

    I don't think youy're reading this right

    192.168.01=is definitely your router, so we can ignore that and go on.

    172.29.78.1=is an internal address--it could be your modem, I suppose, but I wonder if it is a router on your ISP's internal network. Your "modem" may not actually have an IP address. Your dish certainly does not have an ip address. Does a cat5 cable have an ip address? No, it is just a means of signal transmission. That is all your dish is. It would not need an ip address.

    I'll be honest, I don't know. When you log into your router, what is your external (wan) ip address?

    216.197.147.33--definitely a router on the edge of your internal network.

    You say it cannot be your wireless because it worked fine before, but why do you assume that what once worked fine is still working fine? Why can't it be your dish is dirty or misaligned? (misaligned is not the same as not pointing in the right direction)

    Why can't it be signal disruption? It is the most obvious answer

    A small update, tonight it seems like the ping is jumping at the second Hop instead of the third. The average for the second Hop tonight is 113 after running for about an hour and the second hop is just barely above that at 130 which I feel is somewhat reasonable. The max for the second hop is 1013ms and the min is 6ms... That's an extremely inconsistent internet connection if you ask me.

    I use 192.168.01 to log into my router (I just type that into the URL bar of a browser and it takes me to the setup page) and I use 192.168.100.1 to show the status page of my modem.

    Well, what I meant when I said I don't think it's my wireless is that I didn't want people just coming in here saying that "you are on wireless internet, that's your problem." There is quite obviously a problem with one of the parts communicating with another part so I was just trying to avoid wireless internet haters.

    I plan to try aligning the dish again tomorrow if it's not bitterly cold and windy again, but I seriously have doubts that will fix the problem. To me, the ping spikes happening at the second/third hop seem to show a problem very close to my router (which I assumed would be before the dish, but I'm not really sure).

    Hopefully that answers your questions and makes sense.. I'm falling asleep writing this. :rolleyes:

    that first 216 IP is going to be his WAN IP most likely.

    unless his ISP is dishing out private IPs and NATing farther up. which I doubt.

    call your ISP. something is not right.

    Sadly, I've called the ISP about 8 times regarding this issue and they just tell me to go to speedtest.net and get me to run a speed test, but because my download/upload speeds are actually OK despite the ping troubles, they don't understand that there is a problem...

    I don't know how to find my WAN address, but I found this site and it says my wan ip is 216.197.189.130.

    I also went and realigned the dish this morning, but it didn't fix anything :(

    the .33 address is what is causing your problems. you cant control it. your ISP is the one at fault.

    Last night it was the 172.29.78.1 that was causing major trouble, it would take 113ms on average (wow!) just to get from my router to there. That one has to be local doesn't it?

    I think the 172.... address is a network router for your entire wireless network

    Your high ping, in my opinion, is the router at the wireless tower. Your latency is always going to be higher as the signal jumps from your local router to the initial ISP router at the wireless tower station.
