I can make a connection with an open hotspot with no problems and good quality. I need to log in to the server behind the hotspot via browser. Normally this goes smoothly and with no problems, but once in about a week the browser can not make any connection at all, giving an "address not found" error. The server is running as checked with the hotline. As I am not logged in, I can not access any other sites either. DHCP works, as I not only have an IP, but also a default route and a primary DNS. No firewall is installed on this system. Normally this error happens after the Dell went into hibernate. Rebooting the OS or subsequent hibernate cycles do not chance the situation. In fact, the situation changes sometime, somehow, but I don't know why it does in either direction. Does anybody know where I should look to find what the problem could be? </blockquote><div> When this error comes, are you able to ping to that machine using either the IP or the name of the machine ? Thanks, Raseel </div></div>
