Is there any way to improve the time it takes to associate with an
We have a product here which needs to be able to roam between
multiple wifi access points without losing communications for too
long. Our initial implementation used a serial port to wireless
embedded device that took about 9 seconds to associate with an access
point (measured by pinging the devices IP address and timing from
power on of the device to the first ping response). We have now
switched to using mad-wifi minipci cards on an embedded Linux box,
and this device takes about 25 seconds to associate. Is this normal?
Here are our system specifications:
Symbol Wireless network with 3 WAP's connected to a single switch
Soekris 4526 with 133 Mhz AMD ElanSC520
Wistron CM9 Mini-pci cards, which use the Atheros 5004 chipset with
the 5213 main chip.
Our network is set to Open authentication and we use 128 bit WEP keys.
Any comments would be appreciated.

You can help us improving on this issue by delivering more details.
Ideally, you would spend some time on determining what happens in the 25
seconds that are needed to associate, and which of these actions might
be optimized to lower association times.
