Corporate wifi Shows - Connected NO INTERNET - Windows 10 Users, feedback from the users - Wifi Sucks

Team,

We have some weird issue going on for many months, we did much troubleshooting, including the driver upgrade on the clients. but the issue still persists and the challenge here is it is very difficult to collect the real-time logs because we don't know then the issue re-correct. 

 

to troubleshoot this issue we have test SSID as well created, where only very few users associated with this test SSID. 

 

attached is the configuration for our test SSID.. Experts - please kindly review the config and tel us what we are missing from the controller side. we are not sure what is the cause is it controller or client, et... 

 

issue: -

When the users are in the corporate wifi - all of the sudden user wifi shows Connected  "NO INTERNET"

 

Workaround-

Users will have manually disconnect & re-connect. 

 

Client type - Laptop (Windows 10 Image) - also attached the client WLAN report for reference (

Wireless Adapter - Intel various model 

 

WLC - Cisco 5520

Version  - 8.8.125 (We have tried many previous versions)

All the AP's are added in flex connect mode with WLAN & flex connect groups. 

AP Model - Cisco 3802 

Authentication - We were using ISE, then this SSID we have put it on Microsoft radius auth  - the issue is with both auth method.

The client does have the IP address but nothing is reachable from the computer.

I just got an update from the team, they already tried this intel version with wlc 8.5.135 and we had the issue.
We did recently upgraded our controller as well to 8.8.125

thank you

So when this is happening:
1. Are the users getting valid IP addresses?
2. If they still have valid IP addresses, can they ping the default gateway?

If the issue is when they roam, it’s because of the wlan to vlan mapping that might be missing. You should review this and make sure all the vlan mappings on the AP’s are correct. What happens is basically a black hole. Users roam back to an ap and it starts working. I have typically used a cli script to blast all the vlan mapping back to each ap. Reload, ap reboots sometimes corrupt these settings.

Thank you for your reply.
Our issue is not related to the Roaming, the client Wifi sees the error all of sudden in the same place.
