Sounds like a duplex mismatch to me. Are both ends set to auto-negotiate and have they both negotiated 100mb/full? Have you checked for errors or discards on the interfaces at either end?

Ok, Im going bonkers. We are getting ping drops from our Mikrotik devices to the other. Our main router is PC based with one of those 4 port RB cards in it. Starting the other day out of the blue the net started acting funky and we were getting large pauses. So I started pinging. Get ping loss from the main router to everything. average pps going through the router 585 and transfers around 4m at the moment. We switched out the pc and even used an integrated ethernet port on the new pc to check connectivity to the other devices via means other than the RB 4 port ethernet card to make sure that wasnt going bad. But no improvement STILL getting pings loss. Switched cables. STILL. Latest OS. Now here is the wierd part I do not get. We have our backhaul radio connected directly to the onboard ethernet port on the pc router. Running a ping from the pc router to the radio port in the ping specifying to use not ANY but the backhaul port as we labeled it will get us around 10-15% packet loss. While at the same time running a ping from the bachaul radio to the router gets 0% packet loss using the same method. How is this possible? PC PORT (ethernet cable) RADIO ETH = Lost packets Radio ETH (ethernet cable) PC PORT = 0 Lost packets ? -------------------------------------------------------------------------------- WISPA Wants You!
