Coonection lost?

[Luke]

Everything is working fine, except that every few minutes game disconnects from the server I'm playing on, saying "connection lost".

Now, I can't figure if it's just my connection that sucks or something else.

I'm running on winXP. I paste the log from game start to first disconnection (highlighted in red).

Port is correctly forwarded and firewall correctly set.
Btw, the problem began only 10 days ago or so (dunno exactly when, but if it happened before it was much less frequent so that I can't remember).
Ideas?

[Karl]

are you using a wireless connection? Is there anyone else on your network playing Altitude?

[Luke]

I am using a wired connection and no one else is playing.
I tried with the laptop (ubuntu, wireless) and the problem persists.

So I suppose it's just my internet line that is going mad.
Or it's something with the router. The only thing to do is port-forwarding UDP 27272, right?

[lamster]

Yes, all you can do is set up port forwarding and make sure there are no background processes / other people on your network that could be disrupting your connection.

It's sometimes interesting to run a looping ping against a stable internet destination (for example one of google's servers) and against the game server you are playing on (e.g. vapor.nimblygames.com for the "Official #1/2/3" servers) to see whether you have a general connection problem, or it's just the server (or a specific region of your network) that's acting up.

Under windows, open a command prompt (start -> run -> cmd) and type
ping -t google.com (under linux you should omit the -t parameter)
Open a new command prompt and
ping -t vapor.nimblygames.com

Then play on Official #1/2/3. When you're disconnected, immediately tab over to the command prompts and stop the ping processes. If both pings spike (or record lost packets) just before disconnect, you have a general internet problem. If only the game server ping spiked, the game server may be having issues.

[Luke]

This is funny.
While running a looping ping everything is fine.
If I stop it, after some time i get disconnected as usual.
So probably it's my connection unstable?

Anyway, I can just start the ping stuff before playing (I put that in a .bat, so I do not even have to type in the console :P).

There are no problems in having the looping ping running for a long time (till i stop playing)?
