Roaming in 2AP diferent network

Is any idea to build seamless wireless with roaming in diferent wireless network?

Please help me.

Hi sir

you can do it using WDS and brigde mechanism offered by Mikrotik APs/RouterOS.

Several topics on the forum give interesting and working solution to roaming needs.
Just as an example take a look to this :

Hoping it helps you


have a nice day

Thanks for idea, I ever tried using WDS and bridge to build seamles wireless roaming but it just running on same subnet (network AP1=AP2). My scenario is just wireless network support roaming in different subnet AP

for example: AP1 set on network 10.1.1.128/25, AP2 set on network 10.1.1.0/25. First client start connect to AP1 he get IP 10.1.1.130/25. Then he move so that he loss connection from AP1 and automaticaly connect to AP2 (still using 10.1.1.130/25) and his device still can connect to in ternet.

any other ideas?

I see.

Whenever you do not need to implement AAA policy, you can just enable a DHCP service on the Wlans (configured accordingly to your already existsig networks pools ) and using the same wireless security profile on both APs.

Otherwise, a PPPoE Service running on the AP + Radius Service will be a possible solution if you need authentication and protection on the wireless netwrok.


The client has a PPPoE client instance with user / password and on both AP you have a pppoe service running on the Wlan1 .

To authenticate :

  • manually duplicate the same users db on both AP /ppp secrets (useful just if you have few users)

  • freeradius server . in this case both Ap acts like NAS clients to that radius server.



    Hoping this will help you.

thanks guys! Sory, but I still dont understand your clue :frowning:

When device move to other AP on different subnet, how router know that packet data send/forward to client(10.1.1.130/25) via AP2. I mean that normally router will send/forward data to 10.1.1.130 via AP1 (10.1.1.130 => same subnet with AP1)


In pictur below, after client moving to diferent AP, is data flow become (b) or (c)?

Hello,

I need to serve wifi ip phones exactly as pictured on the first post. Which solution can help with it? Client should switch from one AP to another if another signal becomes better. How to do it? I read the forum but still do not understand can I make it with Mikrotik or not?

Its simple.

Set up both APS. Set them on the same SSID, but on different non-overlapping channels. (2 and 8 for example)

Thats assuming you can feed them all from the same DHCP server.

It’s not so simple, if I go from one area to another client will not switch to better network if first is still exist, so voip client will disconnect the call

It depends on the client OS - roaming settings on the client device. If the both APs are bridged in the same Layer2 network then the roaming usually will be seamless.

I tried with windows 7, windows xp default settings and Zyxel wifi voip phone

if a signal from a first AP still available but with low level, client will not switch to another AP with higher level.

check the roaming options in the wifi interface configuration in the windows.
Also make sure that the SSID is the same on both APs.

Uldis,

I will check, but it would be great to have a solution for some common default settings

It is so simple.

WHat you are trying to achieve is seamless handoff - go get a Ruckus access point and WLAN controller.

The client device is the problem here, not your WiFI setup. You have no control when the client will switch channels but you do have some options:

  1. Turn the power output down on the access points so that its not possible to have low signal nearer the other unit.
  2. Ensure wide space and non overlapping channels to aid the client device is switching.

This does work. We have many sites with barcode readers that roam at L2 level across huge warehouses. As Uldis says, check all settings. See what options are available on wireless client devices - Intel cards have a ‘stickyness’ setting that forces the client to switch on lower signals.
