September 13, 201213 yr I have set the MTU setting in the network.cfg file to be 7680 which is the size jumbo frame my nic card supports. When I reboot the computer and run ifconfig, the MTU size is still 1500. The NIC is a TG-3269 - TP-LINK Gigabit PCI. Here is the config, any Ideas?. # Generated settings: USE_DHCP="no" IPADDR="192.168.1.125" NETMASK="255.255.255.0" GATEWAY="192.168.1.1" MTU=7680 DHCP_KEEPRESOLV="no" DNS_SERVER1="209.18.47.61" DNS_SERVER2="209.18.47.62" DNS_SERVER3="192.168.1.1" Thanks, David
