I just got in several RB411L boards to install into CPE. 1 worked ok. The other 2 had problems. They would not communicate with my notebook. My notebook says it is connected but winbox does not show ip address or mac address. I tried to Netinstall 4.17 and they took it. but when they reboot they just keep rebooting about every 30 seconds and never communicate with my notebook.
Now I can't get netinstall to communicate with the rb411l any more.
I tried different power supplies both 24v and 15v, different cat5 cables too.
I have ordered the good old Rb411 to replace these. I just don't like not having a serial port to see what is happening.
