  • Accessing Advanced Wireless Settings for Intel Wireless Adapters

    “Does it matter which wireless adapter is in my new laptop?”

    I get this question whenever a coworker or friend is buying a new laptop. My first answer is that it depends on what they want to do with it. For basic users, no, it usually doesn’t matter. Any old wireless network adapter (WNIC) will provide the same level of functionality – from their perspective.

    Administrators and IT security staff usually want to do more with their WNIC. I always advise those people to buy a laptop with an Intel WNIC.

    Firstly, the Intel design and build quality are superb. They are miracles of tiny performance. For example, here are a couple of photos of a brand-new Intel 7260 dual-band 802.11ac adapter that I received today. I added a US dime in these photos for scale reference.


    Figure 1. Front of the Intel 7260 dual-band AC adapter.


    Figure 2. Rear of the Intel 7260 dual-band AC adapter.

    Do you see what I mean? The design is clean, yet this sucker is powerful. However, the power is only really unlocked when you install the Intel PROSet drivers.

    Windows drivers are able to expose increased device capabilities. This is especially true in the WNIC category. As an example, I have a Lenovo laptop configured with several WNICs as shown in Figure 3.


    Figure 3. Two Intel WNICs and one run-of-the-mill WNIC.

    First I’ll show you the very basic WNIC settings for the 802.11 USB Wireless LAN Card device. I just right-click on the adapter and choose Properties to bring up the connection properties dialog.

    Now I click Configure, and as you can see in Figure 5 this is a RAlink USB adapter.

    Clicking the Advanced tab shows me the sparse configuration options available for this adapter.


    Figure 6. So very few options…

    There’s not much to optimize or configure here. Now compare that with…

    Intel PROSet Wireless Drivers Are Awesome

    I’ve already installed the Intel PROSet Wireless drivers from the Intel Download Center. Now when I bring up the properties and show the Driver tab as shown in Figure 7 I can see that these are Intel drivers, not Windows inbox drivers.

    Finally I can bring up the Advanced settings tab as shown in Figure 8.

    Amazing! I can now adjust just about any capability and setting on this Intel WNIC. These settings are retained across system restarts, so once I optimize the configuration I’m not required to do it again.

      Should the FIPS box be checked in 802.11 settings? I am not sure if i unchecked it during one of my “tinker cluelessly” episodes!
