I get 'AP Mode Not Supported'
If you are running Connectify on Windows 7 or higher then you should be able to share Connectify via AP(Access Point). If this is not the case, please be sure to check that you have the latest wireless drivers installed for your wireless device by visiting the wireless card manufacturer's website or the computer manufacturer's website. If you have an older wireless device that does not support Hosted Networks(AP mode) then you might need to purchase a USB WiFi adapter. You can check this information by opening the command prompt and entering the following command:
netsh wlan show drivers
If your device says 'Hosted network supported: No' then you will not be able to run your hotspot in AP mode. As mentioned above, you can try checking for driver updates that might include support for Hosted Networks(AP mode), but if it doesn't help then you will need to purchase a USB WiFi adapter that does.
Microsoft Surface Users: The Wi-Fi adapter used by Microsoft Surface tablets (all versions), the Marvell AVASTAR, does not support Hosted Network. Older drivers for this card reported that they support Hosted Network. However, all attempts to start Hosted Network fail. Microsoft has confirmed that these cards do not support Hosted Network. If you are running Windows 10, Connectify can create a hotspot using a Surface tablet by using Wi-Fi direct. Connectify is the only Windows hotspot software to support the Microsoft Surface tablets.
Some common wireless adapters that do not support Hosted Network/AP mode are:
Intel 3945 ABG
Intel 4965 AGN
Unfortunately, AP mode is not supported on Windows XP and Windows Vista.
