Client Disconnetion - IP: 0.0.0.0

bernd_breuer — Thu, 08 Dec 2016 10:30:31 GMT

Hello,

our smartphones have no internet after an indefinite time. Both androids and iphones are affected by this. The notebooks work without problems.

If I pull a log from the accesspoint the concerned mobile as ip address the 0.0.0.0. In Zonedirector monitoring, the phone has still hours later a valid ip address.

On Handys the hibernate is disabled. Sometimes the phone works for hours and then again only a few minutes. Even if it is permanently on the table.

This is of course very frustrating , especially since the Ruckus support could not help us.
Any ideas?

I recommend check your dhcp server.

Dhcp server always has enough free ip addresses.
And the notebooks always work.
The notebooks are in the same wlan and are served by the same dhcp server.

Check latency of packet.

Hi TRON,
What ZD firmware version and AP model(s) please?
Does it seem AP model specific, or specific WLAN only?

Hello Michael,

we have a ZD 1200 9.13.2.0 build 33 and 5 R500.
The accesspoints are distributed in the building on 2 floors.

We have 2 wlans and the trouble occurs on both.
But only with mobile phones.

Is it configure device acl?

Re: Client Disconnetion - IP: 0.0.0.0

bernd_breuer — Mon, 12 Dec 2016 10:38:44 GMT

We have no device acl und and no guest portal.
The guests are only in a different network.

I just capture the wlan traffic for the ruckus support.
This can only take a while until the error occurs.

Plz check device access policy again.

That is located under Configure > Device Access Policy.

It is applied WLAN > Advanced Options > Device policy.

If it was configured, It may not receive dhcp ip by the policy.

Regards.

The R500's are attached to a switch? Does the switch log display any dhcp errors?

Re: Client Disconnetion - IP: 0.0.0.0

bernd_breuer — Mon, 12 Dec 2016 16:58:24 GMT

DHCP Server ist the Firewall. There I see no errors.
All wlan zones are defined at the interfaces of the firewall.
The R500's are attached to the firewall.

Did your problem begin after you upgraded to 9.13.2.0 ?

Re: Client Disconnetion - IP: 0.0.0.0

bernd_breuer — Mon, 12 Dec 2016 21:10:08 GMT

No, this problem is one year old.

Re: Client Disconnetion - IP: 0.0.0.0

dtsblake_588878 — Tue, 13 Dec 2016 13:29:03 GMT

To narrow down the problem, you may want to manually assign IP addresses to a couple of test smartphones. If the smartphones continue to be attached to the Internet then your problem may be ruckus or your firewall.

hyosang_choi — Tue, 13 Dec 2016 14:09:14 GMT

Does it supply ip address at Firewall or server?

Re: Client Disconnetion - IP: 0.0.0.0

bernd_breuer — Tue, 13 Dec 2016 14:21:45 GMT

I will try static.
But why does it sometimes work for hours?
And the notebooks always work.
That makes no sense.

I experienced similar issue two times one month ago.

The main problem was dhcp server.

At that time, windows device works good, otherwise apple device works bad.

Reason was very lately reponse packet(dhcp-offer and ack) form dhcp server.

If you meet the problem ervery hours. I think problem is dhcp server.

Regards.

We have had some weird WiFi\Cell phone issues (only on some phones). Created a seperate SSID and only enabled B&G Also rolled back security to just AES. Phones have had no issues since...

Hello,

we changed the channellization from auto to 20 mhz in both channel 2.4 GHz and 5 GHz. In addition, each access point has now a fixed channel. Since then our wlan is more stable.My two test devices (iphone and android) run for weeks without interruption. Before the connection collapsed several times during the day.

Thank you for your support.
