I was playing with ip address in my RB411AH and changed the ip interface in the ip address box from ether1 to bridge1 (i have a lan port and a wireless card installed). neighbor and winbox can find the routerboard, but they can't access to it. it is installed at the top of a tower and i have no access to it. anyone can help how to access or reset it from my computer? I have no experience of working with telnet to setup routrtboards. tnx

you can try to use mac telnet to access it

tnx for reply. i have another RB411, i have tried to test it with this one, but i can't access to it via telnet. it can find it, but it says time out when i am tring to access to it. is there any helpful tutorial on how to config the board or reset it ?

There are pins on Router Board you can short while you boot the system up...
