HOW TO UPGRADE THE ROUTER’S FIRMWARE
Linksys may periodically publish a firmware upgrade either to fix a problem or to
add features to your router.
Important:
Do not interrupt the upgrade process. You should not turn off the router or
press the Reset button during the upgrade. Doing so may permanently disable
the router.
Tip:
Your router automatically checks for available updates and installs them by
default. Use the following instructions only if the automatic firmware update has
been turned off.
