Along with installing the latest  security patch, I tried to go from Cisco WLC 7.4 to 7.6 this weekend.  However, it broke our web auth.  I had lots of error messages from the controller about improper web requests.  The release notes mention something about fragmented requests no longer working, but I didn’t think our web auth additions were complicated enough to cause anything.  Has anyone else seen this?

The issue I saw when I upgraded was that on the web-auth failing was that on the “Management” tab of the WiSM-2, under HTTP-HTTPS, the “WebAuth SecureWeb” was enabled by default.  Our Mac laptops did not like that, so after disabling that option everything was working fine. 




Were you running 7.4 with that disabled as well and 7.6 turned it back on? We are running SecureWeb without issue, however we use web-passthrough.




Did you see this on your anchor controller?

Yes.  It was disabled on 7.4 and was enabled on the upgrade to

Our guest/visitor SSID is web-passthrough.  The welcome/landing page is locally hosted, and is HTTPS – however, we were running previously (not the 7.4 code).  Going from to the (we had gone to actually due to the HA clustering in non-VSS chassis, and then had to upgrade to for a new building deployment of the 3702’s), the “WebAuth SecureWeb” option was enabled by default.  I disabled it, and our captive-portal web-passthrough SSID worked normally from then on.


Yep, it was the anchor.  We had webauth secureweb enabled in 7.4, and it worked ok.

We have the same issue here.





See my post:


Just upgraded our Cisco 5508 to along with the FUS to 1.9, and still having our Web Auth fail with Login Error. (Layer 3 tab set to web policy – authentication). We were at 7.3 before.

The other WLANs are fine, including a non web-auth WLAN using the same Radius boxes.


We can’t really roll back because we need 7.6.1 for all our new 3702 APs.

We tried the fix below (disabling WebAuth SecureWeb), but it’s still failing on login.

No, I just bailed and went to the 7.4 patched version,  I should have done some troubleshooting and opened a TAC case.  Even though this was off-hours on a Saturday I thought, “Yikes!  It’s broken, fix it quick!”

Thanks for getting back to me. I might have to open a TAC, since we are deploying hundreds of 3702s this summer, and need 7.6.
