|Be aware that what Linksys term as drivers are actually firmware updates. Routers don't need drivers in the conventional sense of the word.|
Drivers are an interface between the Operating system and the hardware. Routers do not interact with the Operating System therefore do not need drivers. They interact with the Network Interface Card which in turn interacts with the Operating system via drivers.
As it is a firmware update you will be installing be very careful you have the exact update for your router and follow the instructions to the letter. Get it wrong and you could end up with a piece of useless junk.
