Changing send and recvspace on a router has no effect, except unnecessary taking away memory space. When my ADSL line was upgraded to 896 up /7296 down the only thing to speed up ftp download speed on my workstation was to adjust net.inet.tcp.recvspace to 65536. On my old Pentium II router, I did not have to change anything, those settings are still the default: net.inet.tcp.recvspace=16384 net.inet.tcp.sendspace=16384 [snip] Adriaan
