Unstable Cisco Aironet 1231

I have one Cisco Aironet 1231 access point. It does not use any kind of (server) functionality outside the Cisco device. I have one SSID and uses WPA-PSK (TKIP).

The configuration seams wary straight forward, but something is wrong. The access point seams to be unstable. The clients use long time to connect to the access point and it looses connection a lot of times a day. Can I do something to speed up the ?negotiation process? ? What could be the course of instability?

The configuration was made with the ?web configurator?, but I have a SSH/telnet dump:

Best Regards Martin

Martin,

Your config looks fine. What could cause your clients' problems? Let's see ...

- 802.11 interference from other nearby 802.11 devices

- non-802.11 interference from other nearby 2.4GHz devices

- flaky clients

- poor RF coverage

Tools to use here:

- spectrum analysis

- site survey tool

- wireless sniffer

- client debugs (driver dependent)

Regards,

Aaron
