A few months ago I replaced my router with a new one (a LinkSys WRT1900ACS). It has been working properly. I also attached a hard drive to the router's USB port (works 'ok', too). In the past couple of weeks I occasionally get an message saying I need to update router's driver (see attached). I discussed with Linksys and they are not aware of this message. Linksys confirmed that my router's firmware is current. I've searched the net with little success. I'm reluctant to use this update since I don't know the source. Can anybody shed any light on this? My OS is Vista.driver.png
Your help will be appreciated.
Thanks,
