Resources to help improve or fix connection issues.

Click or the topic for details:

Is your driver up to date?

You don't need to update to the latest version unless you encounter issues. You can resolve many issues by updating an out-of-date driver. Download the Intel® Driver & Support Assistant to automatically install the latest wireless driver and software for your Intel wireless adapter.
You may also manually identify your current driver version and download the latest driver available for your Intel wireless adapter.

Note

Your computer manufacturer can customize drivers and software to enable or alter features, or provide improved operation on your computer.
Contact the manufacturer for the latest updates and technical support information.
If you can no longer get driver support from your computer manufacturer, you can download generic Intel drivers.

Is the Wi-Fi radio on?

If your computer does not see any Wi-Fi networks, verify if the Wi-Fi radio is On.
Select your operating system:

Windows® 10Select the Network icon Network Icon  on the task tray at the bottom right of the screen. Click the Wi-Fi button to turn it on.

Windows 7*Simultaneously press the Windows and X keys. Alternatively, right-click the power iconPower Icon in the task tray on the bottom right of the screen to launch the Windows Mobility Center.
Select Turn wireless on if wireless is off.
Location of Turn off Wireless button

Some computers have a physical switch that controls the wireless radio and overrides the radio control mentioned above. See tips to enable the hardware switch for further details.
 
Is the Wi-Fi adapter enabled?

Go to Start > Control Panel > Network and Internet > Network Connections, and then right-click the adapter. If Disable is displayed as a configuration option, that means the adapter is enabled.

Is the access point or Wi-Fi broadband router functioning?

Verify that your system can connect to your network and to the Internet. Use the Intel® PROSet/Wireless Software manual diagnostics tool to check for possible issues. Contact your access point vendor or Internet service provider for assistance.

Is the network adapter detected?

If you get an error message on boot or at logon, review possible issues and regulatory requirements.

How do you check for sources of local interference?

Check for sources of interference, particularly if using IEEE* 802.11 Wi-Fi adapters working in the 2.4 GHz spectrum. Possible interference sources can include:

  • Cordless phones that operate in the 5 GHz spectrum
  • Microwave ovens
  • Bluetooth® technology-enabled devices
  • Other 802.11 Wi-Fi networks
How do you identify interference or contention from other Wi-Fi Networks?

Make sure the channel your access point or wireless router is using is not overlapping or in use by another nearby access point.

  • Software tools such as MetaGeek inSSIDer* help you select the best channel for your access point or wireless router.
  • If using 2.4 GHz band, use only channels 1, 6, or 11.
  • If using the 5 GHz band, use channels 36, 40, 44, or 48.
How do you disable automatic channel selection?

Some access points or wireless routers try to automatically select the best channel to use. The auto-selection can happen at startup or on-the-fly during normal operation. If you are experiencing random disconnects from the network, try the following:

  • Disable the AUTO setting and manually select a channel.
  • Software tools such as MetaGeek inSSIDer* help you select the best channel for your access point or wireless router.
  • If using 2.4 GHz band, use only channels 1, 6 or 11.
How do you verify and adjust power management settings? How can those settings cause potential connection issues?

The power management or the Power Save Polling (PSP) setting lets you select a balance between power consumption and Wi-Fi adapter performance. See Setting Wireless Adapter Power Management to learn how to change the setting.
You may have connection issues with a Wi-Fi Access Point (AP) that does not support the PSP feature. See Power Save Polling Causes Connection Issues with Access Points for details.

Note Lowering the power management setting can cause the battery to discharge more rapidly when not connected to a power source.
How do you check roaming settings?

Verify that the adapter property setting for roaming aggressiveness is not at the minimum or the maximum. Learn how to configure the adapter settings.

What are the recommended 802.11n settings?

Review the recommended settings for 802.11n connectivity. These include using WPA2-AES security and 5 GHz. If you are using 2.4 GHz, we recommend narrow channels.
 

Note We recommend using channel bonding in the 5 GHz band. We recommend using channel bonding because of the limited available non-overlapping channels in the 2.4 GHz band.
