Best regards Hendrik!!! Most probabily the provider's router is buggy but it solved the problem. The solution was that reported by article pointed by you:
In the mean time, anybody running a current kernel who is having trouble connecting to a needed site can work around the problem with a command like: echo 0 > /proc/sys/net/ipv4/tcp_default_win_scale or by adding a line like: net.ipv4.tcp_default_win_scale = 0 to /etc/sysctl.conf. ------------------------------------ anlater http://studioinglaterza.blogspot.com/ ------------------------------------ __________________________________________________ Do You Yahoo!?
