TomatoUSB

Hello,

I am using Tomato Firmware 1.28.0000 MIPSR2-112 K26 USB AIO-64K on my Asus RT-N66U.
I am very happy how it's running this firmware accept the true-put speed if a switch is connected to 1 of 4 ports.
If I connect 1 of the ports directly to my computer, I have full speed at 120Mps, but if I connect 1 switch between 1 of these ports, the speed drops to 30Mps.
Changed cables to CAT6, no results.
Is this an Asus RT-N66U or an Tomato issue and does someone have a solution for it?

Regards,
Arien

Nobody?
