Hi guys!I am facing a peculiar problem with my 512K Triband connection over a 5-PC network in my office. We run 5 year old Celeron machines on Win2K with the D-Link router connected to one of them via ethernet. All PCs are connected to a hub.Of late, we are facing a peculiar problem where the connection normally chokes, or even dies out around 3-3.30pm. Also, connecting to Gmail thru an email client also becomes patchy. Changing the POP and SMTP servers from gmail.com to googlemail.com, and vice-versa, usually helps. Similarly, sometimes I cannot FTP from the other 4 PCs but am able to do so from the PC connected to the router. Same problem while browsing also.Can anybody shed some light on this phenomenon and how to get rid of it?
