Hi - I am working on an issue and need urgent help as it has been going on since couple of weeks.
We have Anchor (Main) WLC which is working as DHCP server with a lease of(192.168.128.11-> 192.168.129.255) range for guests / visitor wifi.
There are 3 Foreign WLCs connected with WLC which have several APs connected.
Users when connect to wifi are asked for sign-in page where they put username/password (goes to authentication servers) and can then log in and do browsing.
Some users complain when they log in, but they cannot browse. For some users its fine.
What I have done so far:
1. On Anchor controller DHCP leased is set for 1 hour and it has /22 pool but normally during peak hours maximum 150 - 200 appear in leased table. so I ruled out DHCP leased problem or expiry timing issues.
2. I ruled out APs as well as it happens randomly.
3. But on foreign controllers some times, I see below messages :
apf_radius.c:2066 'AcctStop' clt MAC: c8:v6:f5:8a:e6:ab AP MAC: 00:c8:7d:9c:b8:d0 Role 'Handoff' PemState 'DHCP_REQD' SSID 'Visitor' Connected for '4' secs

4. On Anchor WLC I see this in logs:

On non working users, I ran ipconfig / dnlookup / ping to gateway which look fine to me as IP is assigned correctly via DHCP Server / Anchor WLC.
The issue is that they cannot browse. This is intermittent.
What the above logs mean on the Foreign WLC and Anchor WLC ?
Apart from that any other suggestion would be helpful as this is an urgent issue and going on since 2 weeks.
Thanks.
