i tried even RB miniROUTER, stil the same problem
CPU problem?

YES! Also please try to upgrade the BIOS Loader.
download it from: http://routerboard.com/rb500.html
then use the XMODEM feature in Hyperterminal to send the file to the router. Quote:
The boot loader is needed to initialize all the hardware and boot the system up. Newer loader versions might
have support for more hardware, so it’s generally a good idea to upgrade the loader once a newer version is
available. You can upgrade the loader through the onboard serial port using XModem protocol (programs
available for all major OSs). For example, you can use HyperTerminal for Windows or Minicom for Linux to
upload the boot loader. Alternatively if you have a DHCP/BOOTP and TFTP servers available, you can specify
the loader image as a boot image and choose the bios upgrade over ethernet option in the boot loader
configuration menu. The loader will get the image from the TFTP server and upgrade itself. The most current
loader image is available for download on > http://www.routerboard.com> .
The boot loader upgrading is supported also from MikroTik RouterOS. The procedure is described in the
MikroTik RouterOS manual.
Should the upgrade fail, you may try loading secondary boot loader, by turning the board on while the S1
button is pressed. If that works, you should try upgrading the loader again.
I have the same problem on RB112, even before and after upgraded RouterOS. The actual is 3.11.
How can I do that? (I have the radio in a remote station, so I can access it only through radio.)
