Hi, i have this specs

2GIG RAM
80GIG HD PATA
4NIC - DLINK


Captive Portal Enabled.

and it reaches 100% CPU, always 40-70% and sometimes 100%

system --> advanced --> networking is OFF.

top -S -H give me this ..

  PID USERNAME   PRI NICE   SIZE    RES STATE    TIME   WCPU COMMAND
   11 root       171 ki31     0K     8K RUN     85.7H 40.77% idle
   12 root       -68    -     0K   152K WAIT   484:11 11.38% {irq17: vr1}
   12 root       -28    -     0K   152K WAIT   189:06  5.18% {swi5: +}

How much traffic are you passing at that time?
using top -SH is a better measure in my opinion. If you open an ssh session and run top -SH and then open the webGUI to view the dashboard you'll see the CPU usage go up considerably. I.e. simply viewing the dashboard on a system of that type uses CPU cycles. On my own low end P4 it uses quite a lot!

Which options in System: Advanced: Networking:?
