Hi,<br>
<br>
I got an old 10/100 switch with some new cables.<br>
<br>
When I transfer using cross cable the speed is normal (1.5 mbps and up).<br>
When I use the switch with two 5mr cables the speeds are around 150-300 kbps:<br>
<br>
rsync/ssh/scp 250-300.<br>
smb 150-200 kbps.<br>
<br>
doing some tcpdump I noticed ACK retransmit around 3%.<br>
I've Changed the cables.<br>
iptables is not running.<br>
<br>
I'm pretty sure I'm missing something very basic.<br>
<br>

Oh no, not another EDIMAX switch problem. :-)<br>
<br>
Just kidding. Try setting your ethernet parameters to 100m bits per second, and half duplex.<br>
<br>
BTW, are you sure the cables are good? New does not always mean better, or ever working. :-(<br>
<br>
