How do I troubleshoot client device issues? 

Jul 02, 2014 09:13 AM

Product and Software: This article applies to all Aruba controllers and ArubaOS versions.

 

The first step to troubleshoot client device issues in a wireless network is to have a clear understanding of the issue being reported so that the next steps can be efficiently chosen.

 

This table lists several symptoms and possible causes to help you scope the problem.

 

Symptom

Possible Cause

Issue is isolated to an individual.

Might be a NIC-, supplicant-, or driver-related issue.

Issue is isolated to a geographical area.

Might be a RF or other physical layer problem.

Issue affects a group of people on a certain SSID.

Might be an access point (AP) configuration problem.

Issue affects a group of people on a common group of APs.

Might be an AP configuration or a Layer 2 or Layer 3 problem.

Issue is isolated to a certain application.

Might be a routing problem or an application layer problem.

Issue is isolated to a particular server.

Might be a routing or server problem.

Issue is isolated to a particular time of day.

Might be a non-802.11 device, firewall, or service issue.

 

Other things to check:

 

  •  Has anything changed in the WLAN equipment configuration? (All the Aruba Mobility Controllers have an audit log that tracks every GUI and CLI configuration change).
  •  Has anything changed in the network?
  •  Has anything changed in the area of the reported problem?

This flow chart shows you where to start troubleshooting when a problem is reported for a mobile device.
