How do I find out if my laptop's Wifi receiver supports 5Ghz networks?

0 like 0 dislike

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

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)

No, that wireless card does not appear to support the 5GHz band, just the 2.4GHz:

Bands   2.4 GHz

You can also tell it does not support the 5GHz band because it is only 802.11b/g compatible. b and g don't use 5GHz, unlike a (always), n (sometimes), and ac (always).

Sometimes is not a good answer.
@EvanCarroll I think you meant “‘sometimes’ is not a helpful answer”. You’ll note that my answer is not, in fact, simply “sometimes,” but rather pointing out that by examining the protocol(s) supported, one can usually infer whether the 5GHz band is supported. If you see a or ac, you have 5GHz. If you see n, you might (but probably not if you don’t see a, since otherwise there is little reason to drop backwards-compatibility with a).

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
