There are several reasons why your laptop does not recognize new hardware when you install an Intel® wireless adapter.
Some original equipment manufacturers (OEM)s limit the computer to only specific wireless adapters causing an installation error when booting with a different wireless adapter than previously installed in the computer. Intel recommends you contact the manufacturer, vendor, or the source where you obtained your computer regarding availability and support for upgrades of the various Intel® wireless adapters.
Regulatory requirements must be met by the laptop manufacturer to determine if the Intel wireless adapter can be installed in your system. You should contact your laptop manufacturer for more details.
The peripheral component interconnect - special interest group (PCI-SIG) updated their standard, changing the voltage on some connectors. This change affected the Intel® wireless cards which are based on the PCI Express* (PCIe) standard. Due to this change, installing an adapter with the updated PCIe standard version in a system with different voltage standards can cause damage to your wireless adapter, your laptop or both.
Installing or upgrading the various Intel wireless adapters by end users is not supported by Intel.
Replacing an adapter associated with specific wireless software with a different type of adapter may cause your adapter to have issues connecting or give software error messages. For example, if you replace a Wi-Fi/WiMAX adapter with a Wi-Fi-only adapter, you may receive WiMAX error messages and will no longer be able to connect to the WiMAX network.
