INTRODUCTION:
This document discusses the procedures for performing a wireless upgrade
of a Belkin F5D8231-4 v4 running firmware version 4.00.16.
NEW FOR THIS RELEASE:
Wireless upgrade status should NOT be checked by refreshing the
device's "Home" page. Once an upgrade is started (by clicking the
"Check Firmware" button), a small "chkfw" browser window will appear
which will report status.
If all goes well, the chkfw browser window will display "Success"
in 60-70 seconds. The device will then reboot in 4-8 seconds.
See the "OPERATIONAL PROCEDURES" section for more information on checking
status.

mirror site on the "Choose Download Site" dialog.
e. On the "Select Packages" dialog, on the line that starts with
"Base", click the circular arrow icon until the line shows
"Base () Install".
f. On the "Select Packages" dialog, on the line that starts with
"Devel", click the circular arrow icon until the line shows
