Cisco WLC 5508 L3 web auth doesn't work on Broadcom 802.11n

Level 1

So I have

- Cisco WLC 5508 with OS 8.0.120

- AIR-AP2702I

- 2 Laptops with Broadcom 802.11n wireless card

- Laptops with other wireless card

- 2 SSIDs, SSID_A with web auth and SSID_B with normal WPA/PSK

Scenario I have tested so far,

- Laptops with other wireless card connect to SSID_A (success)

- 2 Laptops with Broadcom 802.11n wireless card connect to SSID_B (success)

- 2 Laptops with Broadcom 802.11n wireless card connect to SSID_A (both fail)

- 2 Laptops with Broadcom 802.11n wireless card (qualcomm LAN card) connect via ethernet LAN with L3 web auth (success)

log for normal device connect to SSID_A:

*apfMsConnTask_0: Jun 20 19:12:04.755: #APF-3-ASSOC_TRAP: apf_80211.c:15482 Client Association: MACAddress:ac:c1:ee:89:70:99 Base Radio MAC:00:2c:c8:67:33:90 Slot:1 User Name:unknown Ip Address:172.20.40.31

log for Laptops with Broadcom 802.11n wireless card connect to SSID_B:

*apfMsConnTask_0: Jun 20 19:25:36.442: #APF-3-ASSOC_TRAP: apf_80211.c:15482 Client Association: MACAddress:f4:b7:e2:a6:55:cd Base Radio MAC:00:2c:c8:67:33:90 Slot:0 User Name:unknown Ip Address:172.20.44.10

log for Laptops with Broadcom 802.11n wireless card connect to SSID_A (fail one):

*apfMsConnTask_0: Jun 20 19:05:11.616: #APF-3-ASSOC_TRAP: apf_80211.c:15482 Client Association: MACAddress:f4:b7:e2:a6:55:cd Base Radio MAC:00:2c:c8:67:33:90 Slot:0 User Name:unknown Ip Address:unknown

It seems when Laptops with Broadcom 802.11n connect to SSID_A it doesn't get the IP, so I can't ping nor directed to 1.1.1.1 at all.

We are still in testing phase and so far, only this broadcom 802.11n has problem like this, I'm afraid there are another devices who had similar problem like this.

Any way to solve it without removing the L3 web auth?

Thanks in advance

Can you go to Controller->Interfaces->{select the interface} and check if global proxy mode is enabled/global. Can you change that to disabled and check once?

I change it to disabled but still no change,

results:

- other laptops connect to SSID_A (success)

- laptops with Broadcom 802.11n wireless card connect to SSID_A (fail)
