Client Connectivity Problem

Prasan Venky — Mon, 05 Jul 2021 07:04:33 GMT

Hi All,

We observed all the Nexus 5 model mobiles are not able to connect to Wi-fi network. Any changes on the WLC could help to resolve it ..?

Thanks in advance.

did you tried this ??

On your device, go to System Settings/Wireless & Networks/Wi-Fi, select the Wi-Fi network that you’re trying to connect to, and tap “Forget.” Then reconnect by selecting that network again and entering whatever password that may be needed.

If still fails then...just paste teh exact error what you are facing ???

What is the WLC code you are running. Hope it is not 7.5.102.0 code as it had some bug affecting chrome which is the default browser for those android/google phones

Hi Prasan,

If I find the bug ID, I will post here. But resolution is listed in bleow posts

1. https://supportforums.cisco.com/thread/2241465

2. https://supportforums.cisco.com/thread/2237455

We had the same problem (Android phones cannot get into guest portal https://x.x.x.x) with our Guest WLAN anchored to a WLC running on 7.5.102.0 code. Fix was the above work around if you want to stick with 7.5.x train.

Many thanks to you for this details. If i wish to upgrade it to 7.6 in my 5508 controller, is it feasible..?

I have 3600 AP's with AC module with Auto-anchor design.

Thanks in advance

I think 7.4 series code wont support ac module rit... ???

config network secureweb cipher-option rc4-preference enable

Do i have to enable this command on both anchor and foriegn wlc?? and also what is the impact..?

You need to reboot controller to take this effect.

If all your guest traffic is anchored to one controller, this is only required in Anchor Controller.

But those client get IP from any other controller, you have to do this on them as well

Yes right AC module not supported on 7.4, it is only supported on 7.5 and later versions.

If you have 7.5.102.0 on both wlcs then you have to run this command.

There are open bugs on v7.6 with the 3600's and the 3700's. So your really in a pinch. Your better off staying on v7.5 and adding the command:

config network secureweb cipher-option rc4-preference enable

The open issues with v7.6 is here
https://supportforums.cisco.com/thread/2233768

Your other option is to go with v7.4.121.0 and wait for v7.6 to be fixed, witch will either be a new 7.6.x release of v8.0

I executed that command on only anchor (HA configured) controller and found that anchor took longer time than usual in building a mobility again.(More than 5 mins Wifi was down than expected)

I donno why...? Is this command causing this delay ..?

(Note: After executing this command i did not have nexus5 client to test it... will test it and update here soon)

So you have anchor WLC's in HA using AP SSO?

Thanks,

Scott

Yes Mr. scott!!!

Re: Client Connectivity Problem

Scott Fella — Mon, 03 Feb 2014 04:46:58 GMT

Well HA AP SSO wasn't designed for anchor WLC's. This is used for WLC's that have access points joining to them. Redundancy for guest anchoring is done by two licensed WLC with a 12 AP count.

Now I don't think this has anything to do with your issue since you have defined or should I say isolated the issue with a certain device.
