cisco 2500 wireless controller internal network

Superhornet — Mon, 03 Jul 2023 09:22:20 GMT

Hello I have a cisco 2500 series wireless controller with two AIR-CAP1702I-E-K9 antennas.
Here is my problem when I connect to wifi everything works I can access the internet from my phone or laptop. But on the other hand I don't see any computer or printer from my internal network. Thanks for your help

The printer or PC you want to see is also connected to the wireless?

Can you ping those divices?

If they are connected on the wired network, there is any firewall between you and them? Access list on the wlc or switch?

There is one feature on the wlc call peer to peer block, check if it is enable. But, it would be between wireless device only.

Wire ans wireless device share same subnet ?

So, I ran into a similar issue and I will say to not mix wired and wireless vlans if you need to communicate between the devices.

The issue is a setting under the advanced of the SSID called P2P Blocking Action. The default is disabled which seems like it should be fine, but the devil is in the details from the descrition:

Disabled—Disables peer-to-peer blocking and bridges traffic locally within the controller whenever possible. This is the default value.

The issue we had is it seemed to block arps leaving the controller so the device could not fin the host. It would start working after ~15 min probably when the host arp'd for something and the client learned the host. The only fix we had was to change the vlan and that was fine so long as it had to cross an IP boundary.

Hello, I just scanned the network connect to wifi. I find all the devices. from my smartphone I see them too. However, the service does not work. my smarthpone cannot find my hp printer. I think "mDNS" is not configure right

mDNS is simple to setup. You can follow this guide here

@Dustin Anderson mention, It better to separate the Wire than Wireless subnet.
it many issue not only mDNS
