What is the value of cisco ap9115 route detection default?

[CCC3]

AP9115 is joined on WLC3504.

I don't know what the default value is
Rogue detection was checked.

Will this setup affect the wireless?

After tasks such as poe replacement or ap reboot, the terminals are connected wirelessly, but there is a phenomenon in which they are connected in the state of 'no Internet connection'.

Is this symptom related to that setting?

'no Internet connection'.

with the description mentioned - personally not thinking that issue WLC.(other side may be)

Latest version of windows try to open a edge and check the internet connection, if that fails that shows no internet.

check are you able to nslookup and able to ping 8.8.8.8 and open browser and check any of the web site reachable ?

Do you have any firewall between WIFI clients to internet. ?

[CCC3]

There is no firewall between the client and the Internet,

What's unique is that it doesn't appear in a specific model, but it appears in both mobile phones and laptops

It means that if you erase the ssid and log in new or perform network initialization several times, the Internet will connect.

I don't think there's any problem with authentication because it's psk.

I'm using ap in flexconnect mode, is there anything else I can see?

[balaji.bandi]

 perform network initialization several times, the Internet will connect

is this for all the clients or devices ? or any specific

what code running the WLC ?

So after reboot AP all works is this what you mean ?

[CCC3]

It is the desktop that connects normally after several network initializations.

What code running the WLC means

What happened this time occurred after the replacement of the poe, but I understand that before that, it was also after work such as a reboot of ap.
