HELP!! Need seamless IP environment > 2 APs MESH > 4-VoIP

MY REQUEST - Issue with MESH disconnects!?!!
Would SERIOUSLY appreciate if a Mikro-GURU - (or anyone else for that matter, that I’d be happy to call God - if they know how???)… With an annoying yet important (well to me) issue, I am stumped with!
PLEASE…

MY PROBLEM
We have 2 AP’s at 2 seperate locations linked together >> Both AP’s use the same frequency SSID: TEST-MIKROTIK >> In my attempt to make a single AP Environment - that ALLOWS/ENABLES users - (EG - those using a Voip phone >> to move seamlessly between the two AP’s - WITHOUT getting disconnected with the switch over…

MORE ON MY CONFIG
Currently I have each WIFi AP in Access Point mode; linked together by MESH. Using OSPF for ROUTING. Have NOT setup MPLS or EoIP? Each AP has it’s own DHCP server on the WiFi Interface!

Obviously with this setup - as the user moves from one AP to the other, the stronger signal, switches the client over (to maintain a strong enough signal strength) - and thus, assigns a new IP address for that wlan interface - This change-over obviously causes the disconnect!

HOW do you set-up seamless, singal, transparent DHCP. Should my DHCP server sit on the WLAN interface, or (if possible) should it sit on the MESH interface - (IP address range?). I have not been able to get one AP on the wifi interface to act as DHCP-SERVER and the other wifi interface to act as RELAY - for DHCP to work? What IP range/subnet should the DHCP addresses be? Do I have the Mesh and AP (Wlans set-up/addressed ok for this environment? Is it possible hence, to setup a single DHCP server, with one gateway to the NET! Or do I need to turn on broadcasting?? Can I similarily set-up a seamless - hotSpot environment? I have been using two small and older Cisco–Linksys Routers as my WDS environment before - and never had such complications to resolve…

Is there just a SIMPLER or BETTER way to do this?

MY ENVIRONMENT TOPOLOGY
Dynamically-Meshed AP’s(x2)

AP1-(wlan1)>>192.168.1.1/24 (?) --------------------------- AP21(wlan1)>>192.168.2.1/24 (?)
Gateway Internet Access (here) ------------±------------- Just Wifi Clients (here)
(RB493G) SSID: TEST-MIKROTIK --------------------------- (RB433) SSID: TEST-MIKROTIK

Mesh (AP1)>> 10.2.2.1/29 Mesh (AP2)>> 10.2.2.2/29

I have tried a whole range of different scenarios, and being a bit of a noob… would so appreciate some advice…

PLEASE!!! & THANKS !!! in ABUNDANCE & ADVANCE!!! :smiley: :open_mouth: :smiley:

Cheers…

Hi,

When you change IP you loose connection (aka new device for your VoIP server nad VoIP Client).
You have to maintain the same client IP over your entire MESH network.
You could try setting up a simpler soulution using WDS (downside is badwidth which is cut in half with each AP, but if you have a separate backhaul connection is is ok).

I would recomend separate Bachhaul connection and then make a bridge and use only one DHCP server on the main AP.
Also make sure you specify the signal stregth range so bad quality clients get disconnected or transfered to other AP with better signal..

Thanks for your response Huntah!..

The problem I am still having is allowing the DHCP server on AP#1 distribute its IP addresses across, over to the second AP! If I set the Ap#1’s WLAN IP address to 192.168.1.1/24 do I set the AP#2 to an address of 192.168.2.1/24 or something in the same subnet like 192.168.1.2/24 - then have the WLAN AP#1 act as DHCP server? And have no DHCP/RELAY setup on AP#2? I have tried a few different scenarios, (using DHCP-RELAY also) but the distribution of IP addresses is just not coming through to AP#2! Should I rather have the bridge or mesh act as DHCP Server? I’m not getting past this point! Is there anything I need to do with the firewall(s)?

Have tried this through:

1 > MESH-Dynamic
2 > WLAN AP WDS & Bridge
3 > EoIP
4 > etc

Anyone? Please!

Cheers…

Anyone got any suggestions on this… Would be greatly appreciated! THX

sorry for the late answer I missed your post..

Here is what I would do:

  1. Main AP has connection to ISP (wan) and localnet (Multiple APs).
  2. If you have backhaul connection between APs (ether, wlan) you must put all interfaces in Bridge (Backhaul, Wlan for AP-customers) on connecting APs.
  3. Put IP address from 192.168.1.x/24 to the bridge interface of connected APs (via Backhaul)
  4. Connecting clients will be get IPs from served from main APs DHCP Server (192.168.1.x/24).
  5. You could also make management VLAN for APs if you don’t want to access your APs from the same network as clients

If your SSIDs are the same on all connected APs the clients will roam between them with the same IP..

This is only one way of configuring such a scenario.. You can use WDS or Mesh insted on separate backhaul wlan.

Thanks huntah… Is there another way I can contact you, via email or tel… I would like (if I may) send you a detailed diagram with my setup, to see where I am going wrong - will pst solution here eventually… When it works… I’m still haven’t a problem, andI am sure is just one small thing I am doing wrong!
