That's a single-band card -- 2.4 GHz only.
The system uses the now obsolete half miniPCIe (not the current M.2/NGFF) form factor, so you'll need to look for a dual-band card in that format.
The Intel 7260 card should fill your needs.

You need the half mini PCIe format (make sure you don't buy an M.2 2230 or any other M.2, which won't fit this old system).

Those should work as well.
Remember to uninstall the driver for the existing card before you shut down the system to install the replacement.
