Cannot ping to or connect in LAN controller in packet tracer

chukwuma — Thu, 14 Jul 2022 01:35:34 GMT

I'm using Packet Tracer and Everything was working just fine in a network I'm building.. Not until I wanted to add a wireless functionality to my network.
I then introduced a CONTROLLER to that switch,..gave it an IP addresses and a default gateway corresponding to a Vlan (subnet).

But my challenge now is I can't access the controller from the PCs browser(i.e the GUI), even after assigning the same subnet IP address to the PC.
If I try to ping the IP address of the controller, it also fails.

Please I really need our help.

I attached a diagram of the network here

A common mistake is for switch vlan 1 is considered as untagged but for controller vlan 1 is considered tagged with vlan 1 (not the same thing) , so lets start there, whats the native vlan you are using between switch and controller, try using something other than vlan 1 and match vlan on both sides and see if it works.

Thank you very much for this response, I sincerely appreciate it.
but as you see in the diagram i posted, i connect directly to the
controller with a PC. So there is no way I could change the native vlan
between them. (but if there is a way around there please let me know)

Thank you very much

The topology does not look right, configure a port in access mode, assign it to same vlan as controller management vlan on the switch and connect the PC to that port and then try accessing, provided you can ping the controller from switch first. I don’t know if this tool provides service port on controller, if it does then you can connect PC directly to service port and then access controller as well.

Those are tricky in PT. you can find and open a wireless controller sample in PT. Or you can zip your file and attach it here.

Ping WIRELESS PC to the AZ-RT01 fails because PC belongs to vlan 1 but its default gateway (router AZ-01) is in vlan 10.

Regarding Wireless LAN controller, I deleted one you have, drag new one, connect PC to it, change IP of PC to 192.168.1.x to match default IP of controller,. Now , you can set up new WLC to meet your wishes.
