Dell wireless clients not automatically associating to AP.

[lmoody]

We have a Cisco 5508 controller with 1142 LWAP's running version 7.4.100     We have several Dell laptops which will not associate to the access point UNLESS you stand directly underneath it, power off the wireless, turn it back on then eventually the PC will associate to the AP.   Once the PC is associated to the AP and user is authenticated then all is well.

Any clues as to why this might be happening?    Have tried updating the wireless drivers - downloaded from both Dell or INTEL.   This does not happen to all of our laptops.   However, without making any changes to the WLC or the PC's, we have begun to expirence this problem with laptop which previously did not have this issue.

Well for one, there is a major bug with the 1142 and v7.4. So you really need to downgrade to v7.3 MR1. You also need to check to make sure that these clients are not sticking to an AP as roaming is decided by the client devices.

What is the bug in v7.4?    Also, how do you modify the wireless so it does not stick to an AP?    

This problem occurs when the laptop initially powers up and does not associate to any AP, so I'm not sure it is an issue of sticking to an AP.

Thanks for the feeback.

CSCud97983 is the bug... you can open a tac case and get a TAC release or you would need to downgrade.

Thanks,
