MikroTik hAP AC Lite - VLAN questions/problems
Hi,

last week, by mistake one of my colleagues removed the LAN VLAN 1 from his hAP AC Lite settings. After that, he couldn't access the hAP anymore, so he gave it to me to check. I could access it through the WAN port, went to the settings and added the LAN VLAN 1 again. Now the confusion started:
 
  • When adding the LAN VLAN 1, this setting was never saved. Next time I checked, the field sayed "untagged" again. I've tried that several times, without success.
  • Adding LAN VLAN 5 for example worked without problems...but reverting back to VLAN 1 didn't.
  • After a reset of the hAP, the LAN VLAN 1 was automatically set again - what leads to another question...
  • ...why is it set for LAN VLAN at all? according to the documentation: by default the WAN uses VLAN 1 and the LAN is Untagged on single port devices. 
The LAN ports are accessible again after the reset, but I really don't understand what's happening here...is there something mixed up in the firmware?

Thanks

I don't have a hAP ac lite up and running nearby to check, but most of your post confuses me.  On this device you do not get to control the VLAN settings of the ports, it's one way with no changes.  (I think) Port 5 is WAN, and that's only used to connect to outside network.  Port 1 is the only port with VLAN2 which is AREDN dtd so another node for example.  Ports 2-4 are LAN and so is the wifi if you have it set for access point.

I don't understand your post at all, unless you went deep into the code via ssh perhaps, you don't control which port has which LAN.  You have to have a hAP ac2 or ac3 to change port assignments.

I do, and just checked.  Confirmed, the hAP ac lite does not allow you to change the port or VLAN assignments.

(I think) Port 5 is WAN, and that's only used to connect to outside network.  Port 1 is the only port with VLAN2 which is AREDN dtd so another node for example.  Ports 2-4 are LAN and so is the wifi if you have it set for access point.


Close.  Port 1 is the WAN port (used for tunnels.  Port 5 is the DtD port and VLAN 2.
