Wireless icon shows disconnected while I am connected!!

Hi to all,

I am testing a cisco Wireless access point 1250. The authentication/Encryption details on the AP are as follows:

- Authentication:  Shared
- Encryption: WEP  
- Encryption key : 40bit
- Transmit Key  (1 to 4):  1

I use exactly the same setup on my 3 clients (WIN XP).

I also use MAC address filtering with this setup. On this setup  I have tested many scenarions (add- remove MACs from the list, use different Transmit key etc) and the Client to AP association is working as expected depending on the setup I have on the Cisco Access point.

The strange thing is that when I use the "Shared" Authentication with WEP encryption, the Wireless icon on all 3 laptops shows "Disconnected" always while I am connected to the access point and also have internet access through the  AP.
I don't have the icon problem when I use the "OPEN" authentication with "WPA" Encryption.

Do you have any ideas on why this is happening and how can I corrected. Is this on purpose maybe due to WEP encryption or something on WIN XP ?

Hi before I go any further is there any reasons why you use WEP? It has proven vulnerabilities and it can be hacked into within minutes. Please change it into wpa or something and now check the connectivity icon

Hi and thanks for the suggestion which is very interesting.
 The main reason I changed to WEP was because the MAC filtering wasn't working with WPA (unless I have missed something on the 1250 AP settings), so I tried WEP which MAC filtering works ok with.
I will change it back to WPA. Do you have any suggestion for the WPA with MAC filtering? I am just trying to make this setup as much secure possible.

Thanks a lot

Are you in a home enviroment or business-small-medium. If you are in a home network a passphrase will be secure enough to protect your WIFI. if you are in medium to large business I would recommend certificate based authentication.

I am preparing to deploy this AP in a small-medium business environment. I hope that the 1250 supports certificate based authentication without external server. I will change it back to WPA and I will  have a look on this suggestion.
Thanks for the help again.

It was a suggestion but I would give excellent grade to a detailed explanation of "how to deploy..."
