FATAL ERROR MESS "NET_SENDPACKET ERROR.WSAEINTR

I am using a wireless laptop at a hotel using there connection. When I log
onto Stream to play community war games, it hesitates. and then I lose the
connection and I get the fatal error message Net_sendpacket error.weaeintr. I
have allowed the stream access on Nortons Firewall and Windows. When I try
the stream back at home it works. I am bored stiff at these hotels, can
someone please help me. I want to thank you in advance.
