WLAN PCMCIA card not associated

Hi,
the Cisco AIR CB20A Series WLAN PCMCIA card has got problems to
connect to my WLAN infrastructure environment
At the moment the WLAN is open to keep things simple and the SSID is
used in the Cisco CLient Utility.

Error message:
"your AIR-CB 20A is not associated"

At my laptop I don't see that the WLAN-LED is blinking.
the router can work with this 802.11g-card
I use the latest driver, no errors in the device management

regards
R.

???
The CB20A is a 802.11a only card.
It will never be able to associate with a 802.11b or g Infrastructure.

What "router" can work with a CB20A?

I am using a SMC 2804WBRP-G WLAN

explanation: I read in a different posting that there might be problems if
you use a Cisco .11b card with a .11g-router.
in my environment the PCMCIA-card and the SMC-router are .11g

A cisco CB20A will NEVER be able to associate with your access point

It is an 802.11A   wireless adapter (i.e. operate in the 5 GHhz range)

It will not be able to communicate to an 802.11 b or g access point
that operate in the 2.4GHz range.

If you want a Cisco card that will do this then you need the Cisco
CB21AG wireless adapter

False: as I wrote the CB20A is 802.11a !!!

and the SMC-router are .11g

g and a standards use same modulation in a *different* frequency band.
b and g use the same frequenzy band and g can be setup downward
compatible to b.
You'll need b or g cards (a a/b/g card will work too) for your SMC
AP/router.

Or a Cisco PCM352 or PCM342, 11MBit only.

Hi Merv & Uli

I was so sure that the 20A is an .g-adapter but you both are right.
Well, seems that I have to change it.

thank you anyway, really helped!
