i have an RB493AH as my core router in my home, and from time to time, the switch chip ports seem to just cut the data stream away from the rest of the router with a port not on the switch chip, while still bridging betwen themselves, as they should. (local network works, but the router becomes inaccessible thru Winbox and ping. Only accessible thru the port not on the switch chip.) The problem is usually solved after restarting the router, sometimes requiring 2. I've noticed that the problem is less likely to happen with lower CPU frequency. Also, there is a slightly swollen capacitor, that hasn't been changed, unlike all of the other ones. Here's the config, and thanks for any replies.
