Can't Access aAP ac after setting it up.

RouterOS General
1

I’m using a cAp ac with RouterOS 6.49.13.

I followed this excellent guide to make an Access Point with VLANS. I works great. http://forum.mikrotik.com/t/using-routeros-to-vlan-your-network/126489/1

However, after configureing the device as an access point I can’t get into the router anymore with Webfig or Winbox. I’m locked out. The computer that I’m using to access the cAP ac is 10.2.10.50 / VLAN 10. I suspect the issue has something to do with my computer not being in the correct IP range or VLAN to access the AP, but I cant figure it out.

Attached is my complete .rsc file. I’d really appreciate some help figuring this out.

I think these configs may be the issue but I’m not certain…

Thank you.

Recommend using ether2 to configure the device OFF Bridge.
Below is an examplle.

Change the ipv4 settings on your desktop or laptop to something like 192.168.36.5 gateway 192.168.36.1

/interface bridge
add ingress-filtering=no name=bridgegym vlan-filtering=yes
/interface ethernet
set [ find default-name=ether2 ] name=emergaccess
/interface vlan
add interface=bridgegym name=homeVlan vlan-id=12  { mandatory, trusted vlan must be identified in /interface vlan - do not put any other vlans here!! }
/interface list
add name=ADMIN
/interface wireless

Have you tried through Winbox using the MAC address (which can hopefully be found in discovered)?

Also use safemode when implementing config changes. After about 15-20 seconds, without any issues undo safe mode, to keep the changes and then turn it back on.

Thanks. I did try this but it did not work.

Anav, Thank you! This was very helpful. I got it working. Normal routing is on ether1. Admin access is on ether2 via 192.168.36.1 like you recommened.

I wasnt 100% certain about which parts of the example script “AccessPoint.rsc” at http://forum.mikrotik.com/t/using-routeros-to-vlan-your-network/126489/1 to remove when I added your example script. Attached is my working script. If you see anything obvious I should remove/change/improve/ make more rubust I’d appreciate it.

Thank you again!

Yes.

  1. Major omission! Without this you will not be able to reach the AP for config purposes through normal networking ( winbox on base vlan etc…)
    /interface list member
    add interface=BASE_VLAN
    add interface=emergaccess list=ADMIN

  2. Minor omission
    /ip dns
    set allow-remote-requests=yes servers=192.168.0.1

  3. Personal preference. I always manually write down the untagging on /interface bridge vlans so that they are displayed on an export of the config and to double check against Bridge ports. Also if someone else takes over the config, it will be clearer…

/interface bridge vlan
add bridge=BR1 tagged=ether1 untagged=wlan1,wlan2 vlan-ids=10
add bridge=BR1 tagged=ether1 untagged=wlan1_zz_20,wlan2_zz_20 vlan-ids=20
add bridge=BR1 tagged=ether1 untagged=wlan1_zz_30,wlan2_zz_30 vlan-ids=30
add bridge=BR1 tagged=ether1 untagged=wlan1_zz_40,wlan2_zz_40 vlan-ids=40
add bridge=BR1 tagged=ether1 untagged=wlan1_zz_50,wlan2_zz_50 vlan-ids=50
add bridge=BR1 tagged=BR1,ether1 vlan-ids=99
