Re: Disconnect/Packet loss to game servers

WHen I talked to comcast on the phone the other day they indicated a healthy signal on my end. Today comcast contacted me via twitter saying they checked the signal levels on my modem and there are some signal variances there that may be the source of the problem. So they are sending a tech out. I have tried explaining to them I dont believe its on their end. But the person is sure there is something wrong with my line somehow even though the traces dont indicate any of it.So now there must be something on my end if he sees variances on modem signal.

 

I have tried talking to the game developers, and of course first line support are people who dont know how to read trace reports and they wont esclate it. Also, they said 1% packet loss wasnt enough to be causing the problem so just open ports and it should be fine. I did that and still an issue.

 

Even though all the trace reports indicate nothing on CC end, what are the odds every game I play has a problem when they arent made by the same developer and utilize different servers.

 

Trying to do DSLReport on line test, and i am not pingable, i assume that could be an issue as well. Trying to figure out how to become pingable?

Perhaps those servers are actually located in London and Canada. That's why. And they who ? Comcast ? With the way that the currently used BGP routing protocol works, it is the host / sender that advertises the routes. A few years ago it was just standard BGP metrics that influenced the decision, but today nearly all backbone providers are using technology like intelligent route reflectors to engineer their traffic flows for better performance and to avoid point congestion. This can result in paths being used that are not latency-equivalent, but provide much better service much better service in terms of capacity and packet loss.

Re: Disconnect/Packet loss to game servers

It's something outside of the CC network.  All the traces are showing optimal sub 20ms ICMP responses during the traces.  Open tickets with the game providers and provide the traces and see if they can get the path changed through their providers.

Re: Disconnect/Packet loss to game servers

So I am at a complete loss then at what can be done. Because clearly I am having issues on all 3 games  which makes me think it would have to be on comcast end, but i have no proof now or any actual evidence of that Smiley Sad

Re: Disconnect/Packet loss to game servers

Can't tell you why they're routing the one game to London but the 3rd one you show is going to Canada as well.  1% packet loss shouldn't be enough to knock you out but, it could cause a blip depending on how often it's happening.  Open ports are more for the application to run from the remote servers.  Typically nothing really needs to be done though if you initiate traffic from your connection to their server since this results in a 2-way path.  Now, if you're using a firewall in the sense of a true FW there's a reverse path check that's done and depending on the rule sets can cause issues you wouldn't normally see in a consumer based router/firewall.

Re: Disconnect/Packet loss to game servers

I am confused as to why it would be london? When I am in the US and the game servers should be US located as well.  -Edit-- I was able to contact EA for Battlefield 1, they have a tool that tests packet to their servers, and its showing packet loss but only like 1% and they said I need comcast to open the ports which I already have on my router Smiley Sad

 

Also, please note that this is 3 seperate games from 3 seperate companies. I appreciate everyones responses though. The first one i posted was Battlefield 1, this next one is Rainbow Six and again I am guessing at the IP's.

It looks like the choke point is once it hits London.  As for the one hop with *'s probably has ICMP responses disabled for the hop.

Since the problems occur outside of the CC network there's not going to be much to do.  Providing the traces to the game provider could instigate them pushing the providers to change the route that packets take from the US at least for the London based game.  The US one though could also push Level3 to change their route as well.  It looks like the card they're using on ear2 might have an issue or oversubscribed the ports.  It's possible they have a link down on the chassis that provides IP traffic within the bundle as the AE designation is something you see on Juniper devices when configuring them for multiple ports into one virtual interface.

Re: Disconnect/Packet loss to game servers

I do not have ipv6 enabled on my router currently -No IPv6 address detected

Unfortunately the game servers wont give me their IP. I have pulled what I think are the servers IP which I got from SmartSniff.  When I do a ping to them, I am not showing packet loss, but during the game its giving me the packet loss icon. 3 different games which have no relation to each other.  Here is the Traceert to what I think is the IP

FWIW, The timeouts are not the problem. They are just routers at those hops that are deliberately configured to de-prioritize / rate limit ICMP packet based ping probes. Something else is going on. You do have high latency to the destination server in the first trace. But tracing to Comcast and to Google is not as effective of a test as is tracing to the game server(s) that you are having the problem with.

Disconnect/Packet loss to game servers

Recently I have been battling with a game that keeps disconnecting me from their server. I have done everything I can to eliminate it being on my end. Everything is port forwarded properly. I tested a few other games and noticed I was getting the packet loss icon in completely different games as well. My ping is still good, but the packetloss can cause disconnects. I dont appear to be getting speed issues (except for the extreme cold a few months back)

 

Below is my tracert to comcast and to google. Both indicate a timeout at one point. How can I get this fixed?
