WIFI client devices unable to obtain IP

[nikolak]

Hello Everyone, 

I have very simple setup here. Three networks 10.0.10.0 and 10.0.20.0 with 176.16.0.0 network between routers. All networks are /24.

10.0 and 20.0 are client networks. WLC is configured on 20.0 network, and when i add LAP to that network client devices are able to see SSID and obtain IP address from DHCP server configured on R0. But when i connect LAP on 10.0 network even though it connects to WLC and form CAPWAP tunnel and SSID is visible clients are unable to obtain IP. 

When I set static IP on Smartphone like 10.0.10.50 i am unable to ping LAP on the same network with IP 10.0.10.1.

Please assist and thank you in advance.

Hello,

I have tried pretty much any option available, but could not get this to work either. Is this a project based on  a task list, or are you just experimenting ? I don't want to be cheap, but I think what you come across is one of the (many) limitations of Packet Tracer, where in this case the LAP and the WLC need to be in the same network, otherwise it won't work. I could not find a single example of a Packet Tracer project anywhere where the LAP and the WLC are on different networks...

First of all I want to thank you so much for your support.

This is just my experiment where I am trying to replicate my company network architecture and fill in my knowledge gaps. I'm ferly new in networking/cisco and last few days I'm trying to make this work but without success.

I will accept your answer as solution and move on with my work and move on to other things, but it was still worth it to cement what I learned.

Again, Thank you so much, really appreciate it.

A lesson for anyone else reading this discussion:

Packet tracer is a training tool - not a real network, not real devices.

It does not work like a real network in every way.

It is only capable of performing the limited training tasks Cisco has designed it for.
