Product: Probook 4540s
Operating System: Microsoft Windows 7 (64-bit)

I recently set up a new modem and router capable of using 5GHz. However, my Probook isn't detecting the network. My adapter is an Atheros that is 802.11b/g/n compatible; from what I have read, this indicates that my computer is capable of receiving a 5GHz signal. How can I enable this feature on my Probook?

Hi:

 

There are many 4540s' with different product numbers, which means they all have different options.

 

Most likely your 4540s only has a single band wireless card.

 

If you let me know what model wireless card your notebook has, I will let you know if it is a single or dual band card.

 

It it is not connecting to the 5 GHz band, I can almost assure you it is a single band (2.4 GHz) wireless card only.

That is a aftermarket upgrade that gives you 5g band. By factory default your wifi is 2.4g only. Getting 2.4/5g is dual band and most laptop don't come with this option you must order it installed to get this option if that care is available to your laptop model.
