/at first sorry of my poor English/
today I've got this new AP [topic..], i configured it, and it was working fine while in a few minutes later the winbox connection was aborted.
I reseted the AP, but there are some mistakes with default settings..
the NIC of my PC is working, I tested it. On a router no ping replies, and the MikroTik Neighbor Viewer says, the router has no ethernet connection. IP 0.0.0.0
a page, what I've made while it was working, is still available via wi-fi.
I'm using MicroTik version of 2.9.27
