Re: Wireless Clients are unable to obtain DHCP address

Mr.Mayhem · ‎11-08-2021

Am doing this in packet tracer. I am able to connect to my the AP's are getting an address through DHCP but my wireless clients are not and I am not able to figure out why. I have attached my packet tracer file. Any help would be very much appreciated.

Mr.Mayhem · ‎11-08-2021

a Wireless LAN Controller located on a remote network. This network includes two
WLANs: Admin and Employee.
3 VLANs
• All DHCP will be performed by R1; all hosts (PCs and APs) must use DHCP
• A loopback on R1 to simulate the Internet

Hi,

Did you configure the DHCP for the dynamic interfaces at your WLANs?

"A dynamic interface is used to connect the controller to a VLAN on the wired network."

Inside the dynamic interface you will say which DHCP serve will provide the IPs for your WLAN.

PACKET 7.2

Select the option DHCP, selects the interface and configure the right DHCP for each WLAN

I ended up getting it. I did not have my trunking set up properly also had an incorrect ip on my router. Thanks for looking at it.
