I understand that the WiFi radio will not turn on after installing the Intel® Dual Band Wireless-AC 7260.
Some system manufacturers provide a software switch besides the hardware switch you already know. I suggest you checking with the manufacturer if your model requires any other software tool or relevant (BIOS) updates.
There are a few things to consider when installing or upgrading a half mini PCI Express wireless adapter:
- Just like any other device, not all wireless adapters are physically and electrically compatible with all systems.
- The system BIOS could be designed to accept certain wireless adapter models only.
- The installation of these adapters is subject to country-specific regulatory approvals which include the system, wireless adapter and antennas.
You may also contact your system manufacturer in order to obtain a list of validated wireless adapter models that are compatible with your system.
