Hello, I am currently trying to find out why I am disconnecting from servers when other competitors seem to be fine or doesn't get disconnected while only I do(Doesn't always happen, but it's a pain in the ass if it does!)

I have moved my attention from the servers(They can't be all crap or lagging all the time, can they?) onto my connection, router/modem.

This I posted somewhere else:

Well, I am trying to find the "bug" in the system to race without disconnections.

Can you tell me some things: What is considered a good modem? What should it be able to handle? I have no clue about that stuff, sadly.

Also, how fast the connection should be...

This one here looks like the Linksys modem we have:

http://homestore.cisco.com/en-us/switch ... ewprod.htm (It looks similiar to ours)

What I believe the connection itself is able to perform:

ADSL plus 16000/1000 kbit/s I think... From here:

http://www.solnet.ch/produkte/zugang/adslplus/

Trying to get to know how good it is, there seems to be a 20000/2000 option, but more expensive and not that much better.

Oh:

We have 3 PC's. The router, which is at the same time the modem I think, is connected to my father's PC and the #2 slot is for my laptop.

Does a router/modem like the linksys require a software to be installed on the main PC that it is connected to? And if, do the other PC's need that too?

Best thing would be that I order everything to make it a "racing connection", but you need money for that.

Btw: "rTractor" runs rather fine, I don't get that stuff often when driving in the GPVWC.

This connection exists since about 2007 I think(Before LFS). But only started to get serious during winter 2009 when I got LFS and thus needed the connection for more.

I'd really like to spot the trouble-maker in the system, I wanna race without worrying about the connection(It's not always like that, but it gets annoying when it does).

Well, basically, I need to find out if our modem/router we got in '07 is a total w*nker of equipment or not. Maybe it can't handle the connection's performance?

Or if it is the connection, but I don't really think it is the problem.

Any help is appreciated.

Note that I am a layman, I don't really have a clue, that's why I ask. We also didn't set up the connection and router, it was probably done by network professional, who's retired now from his job.

Getting more and more suspicious about our router/modem, as Tom Parker wrote about his router also causing him to lag or disconnect. Maybe that Linksys modem we have can't cope with the connection speed and makes and makes an "emergency disconnect"?

Anyone able to see what the problem is and can give me a hint?

How are you connected to the router ?
Wired or wireless.

Wired. My father's PC uses port 1, then my laptop on port 2.(Port 3 for my old PC that's now my brother's).

I don't mix up things with router/modem?

It was never a question before, if wired or not. Wireless has some problems, while wired is more "rock-solid", at least in my opinion.

Maybe the modem isn't configurated well enough? But I don't even know if it can be configurated, such a small one...

There are various things that can interfere with wireless (microwaves/lawnmowers/vacuum cleaners/...), which is why I asked.

I presume you have already checked that no other PCs are doing any bandwidth heavy tasks at the time when you have issues (streaming/p2p/etc) ?

The speed of your connection should not be the issue, people have and can game using a 56k dialup modem. What is more important is the quality, how much packet loss between you and the LFS server.

You can use WinMTR to test for packet loss, but will need the IP of the server concerned.

No, I've told my family, and they aren't that much on their PC's, I don't think it's a problem with the bandwith.

Which server do you mean, a LFS server I'd be connected to?

Yes, I mean the IP of the LFS server.

Even if the other PCs are turned on and not in use, they could be getting windows/AV updates etc.

Hmm, true. AV updates are rare though, at least it seems so, and the PC's aren't "on" at the same time as my laptop.

Where is it possible to see the IP of a LFS server?

That means I need to check nearly every NDR server aswell as the Apex Cup.

To get the IP you would need to ask the admins of the server.
They may be unwilling to give it out.

It could be that a lot of servers are covered by a single IP address (500servers for example).

Yeah, that could be troublesome...

How does the packet-loss program work? I enter the IP and it tells me how much gets lost?

It gives output like so...

Sorry for the following, didn't exactly know how to post it

This is a test with the NDR.GTAL server(Thanks to Boothy):

Showing some small amounts of packet loss, but not much really.
Are you having the timeout issues at the moment ?

Right now, in this moment, no.

A week before, at the last iTCC round, I disconnected in R1 and R2.

I lost connection in the main race of the Apex Cup too, after 21/24 laps.

Maybe it's getting heavier with people from the whole world on one server with 30 cars...

Could be time of day/week related.

Your ISP may be filtering or have times of busy traffic (causes loss) during peak evening time and at weekends.

I suggest running the test in these periods.

Oh great, sounds like my connection has periods like a woman

Thanks for the help so far though, Bean0

On Saturday, I ran another test, just before the GTAL race. I got about 3% packet loss, that seemed alright, and it was indeed running smooth.

But come Sunday evening, when being on the Kyoto 250 server, I had about 4 disconnects, before I finally went to the router and re-plugged it with rage.

At least it worked again without problems, but because I was in a hurry, I couldn't test that time.

Still can't locate the problem, it's as you say, maybe heavy traffic.

As for the idea that the router may be broken, wouldn't it be rather 50-50, it either works fine or doesn't work at all?
