Connectify can work in Ad-Hoc mode with just about any Wi-Fi device on Windows 7, Vista, or XP. However, to run in Access Point mode, you must be running Windows 7, and you must have a Windows 7 certified network device driver for your Wi-Fi device. You have this device driver if you own any Windows 7 logo certified Wi-Fi device (laptop, dongle, card, etc.). However, many older devices have also been updated with Windows 7 certified drivers.

Below is the list of devices that have been tested by Connectify, or reported by multiple users, as fully functional with Connectify. New drivers will probably still work fine, but we do not recommend updating your drivers for Connectify's sake if you are currently happy with Connectify's performance, even though the chance is very small that updating a working driver will cause a problem. The following devices are known to be compatible:

• Atheros AR5xxx/AR9xxx cards, driver version 8.0.0.238

Have we missed your compatible Wi-Fi card? Would you like to report a potential compatibility issue? Please let us know. There's nothing specific for any of these cards within Connectify -- we don't have to "add support" for your card to make Connectify work with it. That's the purpose of the network device driver, the bit of software for your specific card that makes it work with everything else in Windows. Connectify will fully function with a properly working Windows 7 certified driver.

Many of the compatibility problems with Connectify are due to older drivers. If you're running Windows 7, you can still have a driver from Vista or even XP. These will handle normal Wi-Fi tasks, but they won't support an Access Point mode hotspot, only a hotspot in Ad-Hoc mode. Older Windows 7 drivers commonly contain bugs that cause your hotspot to drop out after awhile, requiring the hotspot or even the PC to be restarted before it will work again. The fix in both cases is to ensure that Windows is fully up to date and get the very latest network drivers from your PC or Wi-Fi card company.

If you can't find new drivers, either from our links above or from your hardware vendor, you can try one of the "driver update" programs for Windows. If you have an Intel card, you can get the Intel utility for updates, which will find the latest driver for any Intel wireless device. For most others, we recommend Slim Drivers, a utility that is good at finding updates and not otherwise very bothersome.

While Connectify would love to support all of these older devices, it is simply not in our power to release device driver updates. Every bit of wireless hardware has internal details known only to their manufacturers. The purpose of the network device driver is to provide a standard interface to that hardware, so that programs like Connectify do not have to be written specifically to support dozens or hundreds of different devices. If there is no Windows 7 driver for your device, only your device's provider or chip manufacturer can provide the update.
