We have a 192/384 Frame Relay for our internet connection. When one computer is downloading a file the rest of the computers on the network see ping times of over 800 ms and can prevent them from browsing the web or downloading other files. The router we have is a Netopia 4622. Even if I put a bandwidth limit on the firewall to 20K and try to download a file the ping times go up to 800 to 1000 ms. Verizon says we are going over 384 causing dropped packets. I've had dial up and ISDN connections that allow multiple downloads and web access and the ping times never went above 100 ms. Can a setting on the router cause this problem or is this a line problem?
