Globe icon and no internet on windows laptops

[Ramanshu]

Facing globe no internet at windows laptop as soon as connected on ssid getting ip able to ping gateway but not dns and working fine on LAN. Have 3504wlc setup. Issue is occurring on 10-12 endpoints(same) out of 100. Observed working and non working laptops getting connected on same ap as well. I don't think its Wifi and network problem as working laptops are also on same vlan and are able to reach dns. DHCP is configured on core switch. DNS is on AD server.

Does your dhcp scope is big enough?  What the logs from your DHCP server says about the mac address of the failing client?

DHCP apipa problem got resolved automatically but now can't reach dns due to which getting no internet and globe. Have updated the issue post.

Thanks in advance...

What WLC? Apparently 3504

What version of AireOS?

What AP model?

How is the SSID configured: open/auth, if auth what type, flex local switching or central switched etc etc etc?

This is basic info required to begin helping with any wireless problem!

Then what OS is the laptop running?

What wireless NIC?

What driver version running on that NIC?

Have you tried updating to latest AireOS to eliminate known bugs? https://www.cisco.com/c/en/us/support/docs/wireless/wireless-lan-controller-software/200046-tac-recommended-aireos.html

Have you tried rebooting the AP?

Have you updated to latest driver on laptop and checked with vendor support?

Have you run debugs on one of the affected clients and put the output through https://cway.cisco.com/wireless-debug-analyzer/
