[SOLVED] D-link DES-1026g 23-10/100mb and 2-1000mb, internet speed above 100mb, but when switch engaded is 9mb

[Herbata]

Hi, reasently I bought D-link Des-1026g 25 ports, but i have trouble with speeds on it. When pc is connected to router via cat5 in wall i have above 100mb (110 sometimes 120), but when i connect router via wall cable to switch in my room and switch to my pc, on pc i only have 9mb max 10mb. Why it isn't 100mb? All my ethernet cables are cat5.

i was thinking that 24 and 25 can pass speeds to 1000mbps, not that they support more than 100mbps
in a moment i will try that
