Get tftp.exe from:
<ftp://ftp.linksys.com/pub/network/tftp.exe>
Get the firmware from:
<http://802.11junk.com/jeffl/crud/BEFW11S4v4/v1-52-06/befw11s4_v4_v1.52.06.bin>
Rename the firmware filename to "code.bin"
A note on tftp & the befw11s4_v4:
Do not try to start the tftp pgm at the same time as the befw11s4_v4
is powered up (as with a wrt54g).
It seems the befw11s4_v4 will (only) respond to a tftp firmware
download anytime _after_ it has been powered up.
Therefore I suggest disconnecting the befw11s4_v4 from all lan & wan
connections, other than the computer doing the firmware update.
Power up the befw11s4_v4 & check you can "talk" to it.
Reset the befw11s4_v4 to factory defaults via the HTML interface.
You should now be connected to the befw11s4_v4 at 192.168.1.1, login
"admin" & password "admin".
The router is now ready to accept the tftp firmware update.
From your computer dbl-click or run tftp.exe.
Enter the following:
Server: 192.168.1.1
Password: admin
File: [enter the location of the "code.bin" file you just renamed]
Click "Upgrade"
It didn't take long to flash the upgrade, 15 sec. as I remember.
The tftp pgm will respond with a upgrade complete.
Wait a minute or so then try going to 192.168.1.1.
It should show "Firmware Version: 1.52.06" :)
I did a hard reset after flashing the new firmware (hold the reset
button depressed for 30 seconds).
I have 15+ hours on the 1.52.06 code & it is running OK.
NOTE: This code has no "release notes"! There is _NO_ support for this
firmware.
I have attempted to describe how I got my befw11s4_v4 to run 1.52.06
firmware.
Your results may be different.
It may fix some problems that I & others were having with the 1.52.02
firmware.
My befw11s4_v4, running 1.52.02, would lock up or "freeze" at anywhere
from 5 minutes to 12 hours from power on.
It is not doing that now.
