Internet drops after creating VLAN's

Dear Support Team,

I recently purchased the following MikroTik products for my home network:

CCR1009-7G-1C-1S+ Router
CRS112-8P-4S-IN PoE Switch
cAP ax (C53UiG+5HPaxD2HPaxD) x 1 (Wireless for phones and laptops)
hAP ax² (C52iG-5HaxD2HaxD) x 2
RBGrooveGA-52HPacn (wireless for IoT)

I have configured PCC load balancing on the CCR1009, utilizing the combo port in the bridge, with ether1 and ether2 connected to ISP1 and ISP2, respectively. The CRS112 switch is configured as a bridge, primarily for PoE purposes. Wireless is set up on the CCR for the cAP ax and hAP ax² devices, which are functioning correctly. Additionally, I configured CAPsMAN for the RBGroove, designated for IoT devices.

I aim to create two separate networks:
10.10.10.0/24 for computers and mobile phones
10.10.20.0/24 for IoT devices

To achieve this, I created two VLANs, assigned the respective IP addresses, and configured DHCP for both. In the wireless configuration, I assigned VLAN 10 to the cAP ax and hAP ax² in their datapaths, and VLAN 20 to the RBGroove via CAPsMAN. However, after applying these settings, devices on both VLANs lose internet connectivity.

Could you please assist in troubleshooting and resolving this issue? Any guidance on the correct VLAN and DHCP configuration would be greatly appreciated.

Thank you for your support.

First … this is a user forum. Users helping other users.
No commitments, no strings attached.

Having said that …

Usually issues like these are best solved when the user provides an extract of current config on router.
(minus serial number, passwd, public WAN IP,…)

One comment already however:
I see you mention cap AX and AX2 being controlled via capsman.
And then there is RBGrooveGA-52HPacn … that device can NOT be controlled by the same capsman controller. Different wifi drivers, not compatible.
Or did you configure that one on legacy capsman ? For 1 radio ? A bit overkill then …

It might also help us if you provide a small drawing (can be on paper) indicating how all devices are connected to each other.
Makes it more clear to see what needs to be configured where.

Dear holvoetn

Sure, thank you so much for your prompt response.

I am attaching the current setup as advised. Yes as you suspected, while configuring I noticed the Wireless option from the winbox i used to configure ax devices and for RBGroove I used CAPsMAN option I believe it to be the old one.

My current configuration:

  1. Ethernet 1 ISP1 DHCP client
  2. Ethernet 2 ISP2 DHCP client
  3. Created bridge named Samcomm_LanBridge and added combo1 port to it.
  4. configured PCC to loadbalance and failover. (I followed the same what showing in the link https://www.youtube.com/watch?v=LPKzelijfeQ)
  5. configured ax devices for wifi (I followed the same what showing in https://www.youtube.com/watch?v=bHotZT41w3E&t=115s)
  6. similar to step 5, I configured capsman which showed me the RBGroove and congigured the same. Screenshot I uploaded in the attachment.

My requirement:

  1. I want two networks, one for all my device which connect to ax devices, another one for device which connects to RBGroove device. for example the wifi devices which I will connect to ax devices should get 10.10.10.1 ip address and the devices which I am going to connect to RBGroove should get 10.10.20.1.
  2. Both the network should have the internet from Samcomm_LanBridge

What I did:

  1. Created two vlan interface under Samcomm_LanBrigde vlan10 and vlan20.
  2. Created ip address for the both vlan’s
  3. Created dhcp for the both interface vlan with 10.10.10.0 and 10.10.20.0 respectively.
  4. Created vlan and tagged Samcomm_Bridge and combo1 in bridge under vlan. Named vlan10 and vlan20.
  5. And enabled vlan filtering to the briged.
  6. Added vlan10 to datapath in Wireless option for ax devices.
  7. Added vlan20 to CAPsMAN datapath.

what happened:

  1. If I update PVID of combo1 in bridge in router than all the devices can connect to internet and RBGroove unable to connect, what i noticed in the bridge->port window the caps1, caps2, caps3… the same interface was keepon chaning the name for some reason. I think the RBGroove was unable to connet.
  2. Also if i connect to vlan20 somehow, I wasn’t getting the internet.

Please help!

Thanks & Regards,
Yousuf Sait Ismail

Config pls ?

Hi holvoetn

Sure, added the configuration of the router. Also, what I noticed today is the devices connected via ax devices are working fine. However, the RBGroove is not connecting also the RJ45 ports in ax devices are also not connecting to the internet.
myconfigccr.rsc (5.38 KB)

Can you also adjust your diagram indicating which links are trunk (for which vlans), which are access (which vlan) ?

Sure, modified the diagram.
Wanted to mention that I haven’t configured anything in the CRS112. It just has the default configuration. All the ports 8 ethernet and 4 sfp ports are bridged together.

You might want to handle that CRS112 first then.
If you use VLAN, all intermediate devices need to handle it properly.

How are your access points controlled ? On which VLAN do they get their IP address etc ?

I sense something is still missing …

ax devices are getting the IP address from VLAN10 which I am adding in the WIFI controller Datapath.

ok, So I have to create vlan in the switch as well? I am just curious to know why the CRS112 has Router OS instead of Switch OS. Do you have any sample video to configure the same?..
