Flex Connect Smart Phone Issues

Hi All

I have a 5508 controller with 7.4.100.0 code supporting Cisco 1142N and Cisco 3602I and Cisco 3602E APs.

I have flex connect set up with a guest WLAN configured with web auth.

I am using local switching and central web auth.

A laptop connects fine to the guest SSID.

An iPhone and Android phones fail to get an IP address.

An Android tablet shows the same issue.

Anyone seen this before?

Regards

Roger

Re: Flex Connect Smart Phone Issues

A few things here. The version you are on isn't a good code. I suggest looking at v7.4.121.0. Since this is WebAuth and other devices are fine... Does the devices see a splash page or doesn't get that far because of not getting an IP? Can you post your show WLAN

What state is the client in also?

Flex Connect Smart Phone Issues

Hi Scott

The WLAN is configured as Open with Web Auth. FT is disabled.

The client doesn't get an IP address so no splash page as yet.

The client is an Web-Auth Reqd state.

Re: Flex Connect Smart Phone Issues

I have many customer where I'm also doing FlexConnect and using the WLC for WebAuth and I have not seen an issue like that at all.  Either all the devices have issue or none... Is the issue with all iPhones and iPads or a few?  Can you post the show wlan

You are not anchoring or are you?

Thanks,

Scott

Roger,

The WLAN looks fine... nothing has changed on the WLAN and this has been working for a while?

Thanks,

Scott

Flex Connect Smart Phone Issues

Hi Roger,

As Scott sugested upgrade to 7.4.121.0 & start troubleshooting.

Knowing the code you are running is buggy, not point spending lots of hours to troubleshoot with a code like that. Also upgrade your FUS to 1.9.0.0

Flex Connect Smart Phone Issues

The issue was an extremely strange problem with a DHCP Server.

It was resolved by temporarily moving the DHCP scopes onto the firewalls.

The DHCP Server just happened to have issued IP addresses to the test laptops but then stopped working.

The server is currently being rebuilt.

Re: Flex Connect Smart Phone Issues

So since the issue was with smartphones only, was it due to the lease for those addresses?
