I was disconnected to three AP’s while trying to reconfigure. Now they have 0.0.0.0 IP and will not connect using winbox. Yes that includes trying to use the MAC address. WHITE HOUSE 1 works perfectly. The others just do not connect.
Was your PC connected via cable to any of unaccessible AP’s?
There could be issue with firewall/filter.
Also, is there any routing protocol involved in your setup? CAPsMAN? Its hard to blind guess issue without posting your config.
I disabled everything. Firewall, Antivirus, Network cards even alternated between wireless and cable network. Still notihing.
Network adapter, have some IP?
Is needed to connect via mac-telnet, can be any IP with netmask (static or dynamic).
Example: IPv4 link-local or some 10.1.1.3/29.
Also, update the winbox to last version (3.11).
Nothing seems to work 
I could send you team viewer details you try. I am out of other options.
We can try connect via team viewer.
Do you use irc? You can found me in Rizon Network on channel #mikrotik
Hows about you just mail me on crawleyobara@gmail.com then we move to team viewer
Ok, it’s easy too.
This is why i have enabled IPv6 option on my routers. Always can connect via IPv6.
I have the same problem.
RB750Gr2: More or less default Home AP config. Firewall filters all off. PPPoE on ether1 OK. No LAN IP address set. Tried ether 2, 3, 4 or 5 cable to MacBook Pro. Winbox visible but unable to connect via MAC address. Winbox access via Internet is OK. I haven’t spend much time on this yet. Will report back with more info.
On the other:
RB2011UAS-2HnD: No IP address, minimal config, currently it’s just working as a VLAN switch, ether 2 cable to Hackintosh: No problem. Winbox able to connect via MAC address.
Something else you can try is to log into the one you that you do have access to, and try to connect to the others from it using:
/tool mac-telnet
I had connected in the network of K79, but three Grooves are inaccessible. Only one groover is working. I tried to connect by mac-telnet via the only groove and without success. I only saw packets of broadcast and discovery from Grooves, nothing else. Also, the winbox isn’t a problem, because not connect using versions 3.9 and 3.11.
I suggested to he to reset physically these Grooves and update to ROS 6.38.1.
All ports from RB2011 are in bridge, except the ether1 which is WAN.
There it is again. Mention of IPv6. Often times, when I hear about IPv6, someone is saying something about network problems disappearing.
I work for a small company with a network of less then 255 devices.
I’m having that 0.0.0.0 problem, myself. Would it be worth it to migrate to IPv6? What are the drawbacks?
My company has a server running DNS and DHCP and a virtual machine running Unifi Controller for Ubiquiti Access Points.
I suggest running both until you’re ready to leave IPv4 behind. IPv6 has many advantages, and the time running both will give you time to learn IPv6 without the crash course effect.
