Windows – How to find out if the laptop’s Wifi receiver supports 5Ghz networks

networkingrouterwindows 7wireless-networking

I have a Windows 7 laptop which does not show 5 GHz wireless lans in the wireless network settings.

How can I find out if the 5 GHz range is just not configured (i.e. Switched on) or if this is not supported by the hardware?

Laptop is asus. 4 months old. Windows 7 Premium N55SL series

The laptop has a centrino wireless n 1030 and when i look in its properties, advanced tab
i see:

  • 802.11n channel width for band 2.4 and value is 20 Mhz only (other option there is auto)
  • 802.11n mode (opt. there are enabled or disabled) and its enabled
  • ad hoc channel 802.11b/g value here is 11 (you can add or subtract numbers)
  • ad hoc QoS mode here value is WMM disabled

other blahblah values and later i see

  • wireless mode and value is 3.802.11b/g (other opt. are /b or /g)

Driver is 14.2.1.1

I have a new fiber router that can broadcast on both frequencies so I would like to use them both (router is ok. My phone sees both the wifi networks)

The general solution on Windows is to run the following in Command Prompt:

netsh wlan show drivers

Look for Radio types supported in the output. If you see 802.11a in the list, 5 GHz networks are supported. Otherwise, as in this example, only 2.4 GHz networks are supported:

Radio types supported     : 802.11n 802.11g 802.11b
