The Intel® Dual Band Wireless-AC 7260 requires 2 antennas for proper operation. If the PC only has one, it means that it was not designed to use this type of adapter.
Please keep in mind that custom integrations are not supported by Intel since this may lead to installation errors, connection issues, software error messages, and in some cases it may even be illegal.
Intel does not recommend end users install or upgrade the various Intel® Wireless Adapter. You should always contact the Computer Manufacturer or its authorized representative to check which adapters are supported by your PC and have it replaced with them whenever possible.
