disconnect on loading new area

[LordBraindead]

As the title says, whenever a new area is loaded (login, teleporting, entering a house) there is a 4 in 5 chance that I get disconnected and returned to the login screen.

These disconnects have happened now and then in the last week but are happening all the time since yestersay.
Once I manage to log in, the client is stable. I went foraging for an hour without problems but crashed again when entering my house.

Im running Win7 HPr 64bit and have a Radeon HD 3450 Mobility with the latest drivers and triple buffering dissabled.
The problems occur with enders and the native client.
Salem and java caches where cleared without success.
Reinstalling Java 6 didnt help either.

If you're crashing, you should be getting an error report. Post the exception(s) that are occurring.

At the time of posting, I hadnt gotten any error reports but my girlfriend managed to get this one today.
Im not sure if it is related but its worth a shot.

I don't think there's any direct fix on this. Given the information, my guess is some sort of network problem. It could be intermittent and will only be an issue for a day or two. You might be able to do something on your end to resolve the matter. Check your security software and router to make sure proper permissions are had and ports open (TCP 1871, UDP 1870). Check with your ISP to see if there's any network connection issues.

Thank you very much. At least I can stop fiddling around with my graphics card then.

I got a few programs that might cause problems with ports, gonna check them now.

Hello,

i got the same problem as is mentioned above.

I get disconnected when i load in a area with many buildings, for example when i get out of my hovel.
I sometimes have to try 20 times to get in the game, but after that it is stable.

Can anyone help me?

Using java 6 on windows 7 64bit with Enders client. Edit: with the original client i got the same problem.

I dont have enough knowledge of internet etc. to be able to tell what went wrong but apparantly it has got something to do with my internet connection. I am using a system that transfers the internet signal over the electric power net, so that I dont have to use cable from the router to my pc.
I reconnected that system because of the advice given above and it seems that the disconnection on loading area has significantly decreased. Not totally stable though, but maybe i should use a direct cable for that...
I hope this information will help other people having the same issues. If anything happens i will make a new post.

[MagicManICT]

Thanks for the follow up on that, Klabam. It's the small details sometimes that can be most important.

I can't really comment on the electrical wiring based networks as I've never dug too deeply into them. (They weren't much cheaper than shoving 50 feet, about 15 meters, of cat 5 through my walls.) The only thing I do know is that they can have noise issues based on the electrical supply running through them.

[Klabam]

Thanks for your reply.

Well i am still figuring out if the network is the problem.
The reason of that is because the disconnetion only happens in crowded areas. When i connect whil i am in Jamestown, my hovel or the wilderness no problems occur, but when i am near my homestead with buildings all around the problem is there. It sometimes takes up to 25 tries to connect...

Do you think that my network configuration would have effect on the place i log in? More data or something?

So when anybody else has a solution to the problem, please feel free to respond.

[Klabam]

Update:

The more i build the more difficult it gets to get into the game. I build a part of a stone wall and now it is almost impossible to get into the game. I am thinking about quitting, because having to try to connect about 50 times aint fun... But sometimes it is "only" like 5 times...
It also happens when i get out of my hovel or when i return from Jamestown, so i cant even lit a torch from my stove whitout much troubles getting into the game again.

Again: if there is anything i can do to solve the problem, please help me.

I also found out it has got nothing to do with the connection. I am using a glassfiber connection and using a direct cable to my computer does not make any difference. Also when i connect in the middle of the woods, i dont have a problem. It only happens in build location like my homestead or near the homestead of my neighbour.
