Normaly i using two networks, first one is in my office (normal cable) and secound  what  i use is inmy house (router + wifi inmy notebook)
From yesterday i cant play in WA inmy house coz snooper  make me disconect with any information, and when i try to enter using WA i see message
" Server error: Closing Link eVo'Berria[Username@255.255.255.255] (Banned)

what should I do?

I had a similar thing once where I was logged into WN already with snooper and when I tried to launch it failed But I think it said something more along the lines of  "username already in use" rather than "banned"

Try changing username and logging in that way, I doubt this is what you meant but thought I would offer a possible simple solution.

The other is reset your router.

gl either way I'm sure it wont be too serious of an issue

 thx man, i know then it cant be big problem...but i tryed to reset router, chenge username and others .......
its just annoying   i cant play
