Well as this seems not only to affect routers but also turns some ISPs to shut off the connection for some people I think this problem should get a lot more attention.

FireBreath,
yes it is probably an issue with the router.
Finaly checked mine and it also "hangs up" because of to many connections.

Doesn't change the fact that every other game out there can be handled by my router.

Holy Shit guys, lets be clear on one thing...
Its a SERVERBROWSER ISSUE... A DayZ ISSUE.
Its NOT a router issue.

EVEN if a stronger router can "solve" this issue, the issue is caused by the game.

If I eat 100 different brand of apples and I am allergic to ONE brand of apples then I am not starting to eat bananas. I am allergic to that specific brand of apple and I will just avoid that specific apple...

You get the point?

Can someone confirm that this is a "router problem".
E.g connecting the computer directly to the modem and look if the problem just stops?

Would do it myself but with my ISP I cant just request to change the mac adress.

@Dogmeat:
The number of Servers should be irrelevant.
The Serverbrowser shoud NEVER flood the router/pc so much that it just shuts the connection of.
I mean it is a serverbrowser... not and HD Videostream @ 4MB/s

So I finally have time for it and can confirm that this bug still exists in .30

I can also confirm that this bug still exists in .29

As far as I have read you can change the "connections at once" in DAYZCommander.
But i havent seen a option in DayzStandalone for that.
