    I have a cisco 2600 series router connected to a stack of 3com 4400 series switches. From the router I have a single T1 to the internet. If I connect directly to the port on the router with a x-over cable my internet connection is fine. But if I connect through the stack of switches my connection is unstable. I will be surfing the net and for some unknown reason I am unable to access any sites. I can still ping the router but no outside address. I am loggin in to an nt 4 machine running dhcp but that makes no difference if I set a static ip and don't log into the server it still will lose the connection. Any suggestions?

    Do you have a proxy server? The settings on that will prevent you from surfing sometimes. If not ... might be a DNS problem

    Are those managed switches?? If the port you are plugging into isn't configured properly you won't go anywhere. Do you even get a link when you connect to the switches...activitly LED's etc?? Try a XOVER cable to the uplink port on one of the switches and see what you get.
