hp 4540s with ralink adapter cannot detect wifi network

Hello I have a customer who purchased  HP 4540s notebooks with built in Ralink adapter cards. It does detect a lot of networks (2,4Ghz and 5Ghz) but not those of the Cisco AP's , connected to a 2504 controller. All other equipment can connect to this controller, but not these notebooks.

According to some forum posts throughout the internet, these Ralink adapters give issues with Cisco wifi, especially with windows 8.

My question is: Which wlan adapter card is confirmed to be supported by the 2504 wlc / AP1042 accesspoints?

Or does someone know if there is a list that can be checked?

Thank you for any help.

Kind regards,

Ralph Willemsen

There are a couple known issues around Windows 8.



Check to make sure you are not running version affected by these, or that you implement the workarounds.

Also, you might try turning off the aironet IE under the WLAN as this can cause some clients to have issues.
