How to fix the WIFI breakdown with CISCO Access-Point Aironet Series:

WiFi Troubleshooting Cheat Sheet & Video

Three easy step approach to basic WiFi troubleshooting:

1.       Check if the AP, where the client connects, is turned on and is responding to the pings or is listed in the WLC list of registered AP’s.

2.       Ask client to turn off Wireless adapter and explain step by step the issue they are experiencing:

a.       Verify that your client's wireless adapter is installed and working properly On a Windows client, select your wireless connection from the Network Connections panel and verify that its status is "Enabled."

b.      Make sure that the DHCP server is operational and reachable from the access point's LAN, and that the IP address pool has not been exhausted.*

c.       If the client is completely unable to connect, it is possible that either the client is out of range of the AP or the AP is dead.

d.      There can be a third party Wireless NIC application not letting the client to connect.*

e.      WiFi turned off in client’s PC.

f.        Ask the site technician to check if there are lights on the AP and to track the switchport the AP is connected to and verify whether the port is “UP” or not.

g.       Ask the technician to power cycle the AP.

h.      If the AP is reachable, verify AP configuration.

i.         If RADIUS is working but the client's access requests are rejected, look for an 802.1X Extensible Authentication Protocol (EAP) or user login problem. The client must support one of the EAP types required by your RADIUS server and must supply a valid login and password/token/certificate or other kind of credential.

3.       For slowness and intermittent connection issues please follow the below:

a.       Check for EMI (Electro Magnetic Induction) devices such as Microwave producing equipments, thick walls, metal gates etc.

b.      Check if the number of clients registered on the AP does not exceed 20 as recommended by Cisco.

c.       Check gain, power, signal and channel settings on the AP.

d.      Verify AP if the AP is running in good health. The CPU utilization, temperature and memory utilization should be below the specified threshold levels.

e.      Check the switch configuration and verify that the switch is running in good health. The CPU utilization, temperature and memory utilization should be below the specified threshold levels.

f.        Check for crash on devices if any.

g.       Check power supply to both the devices.
