RouterBOARD Troubleshooting
This page describes methods of testing if a RouterBOARD device has troubles. Before contacting support, or RMA department, please carefully try ALL of the mentioned methods:
Can't connect over IP or MAC
- Try to connect over a different ethernet port
- Try another cable
- See what is output on the Serial console (next sections)
Boots, but stops loading after BIOS info
- Check if the baud rate of your terminal program is set correctly, usually it's 9600 or 115000
- Try using mac-telnet, or mac-winbox to connect
- Make sure your RouterBOARD's BIOS is set to boot from NAND
- If all else fails, hold the button next to the LEDs to load backup BIOS
Starts, but an ERROR interrupts loading of RouterOS
- Enter the BIOS, set it to boot from "ethernet, then NAND" and reinstall OS with Netinstall. In most cases, it will not hurt the configuration or license.
- Examine the error message and see if it's meaning leads to a logical solution
- Contact support with the error message
No information on the console output
- While turning on the device, hold the button next to the LEDs to load backup BIOS
- Check if the baud rate of your terminal program is set correctly, usually it's 9600 or 115000
- Check Power jumpers, are they set according to the manual?
- do any LEDs blink or turn on? Clarify their meaning with support
Operational Problems
CPU load 100% or slow traffic speeds: Check traffic coming to/through router with Torch Tool. Disable interfaces. See if a P2P user, or an attacker is not causing it.
Wireless card disappearing: Check if the pigtail or something else metallic is not touching the wireless card's metal parts.
