Updating Firmware with aMac

Linksys provides Firmware updates for the router in a Windows self-extracting zip file (.exe extension).  Although this file tin can exist expanded via Stuffit Expander (you may have to modify the.exe extension to go Stuffit to work its magic) to get theCODE.BIN file that contains the firmware, the Windows-based TFTP client that’south included with the update won’t exist of much utilise on your Mac.

Read:  Canon 7d Mark Ii Latest Firmware Version

In that location are multiple means to upgrade the Linksys firmware with a Mac-but network:

  1. Use Kem Tekinay’sMacTFTP Client.

    (This will work no matter what firmware revision your router has.)
  2. Use the built-inJava upgrade client.

    (This volition piece of work only if your router has V1.22 firmware or college already installed.)
  3. Try using
    MaxGate’s MAC updater
    . (Thank you Jonathan Gahan!)
  4. Use
    MacTechnologies’ MacTFTP client
     (requires PPC and MacOS8.1 or higher).

TFTP method

Kem Tekinay ofMacTechnologies Consultin1000 has writtenMacTFTP Customer.  This fiddling shareware gem is a TFTP customer that supports both Transport and Receive to and from any TFTP server.  You just input the IP address of the TFTP server, blazon in the server’s password (if needed), select the file you want to transfer and hit the Start button. The programme is free for thirty days, after which y’all’ll need to register.
Go here to download MacTFTP.
(Thank you go again to John Strung for this tip!)

Java Upgrade Client method

In one case you lot get the
V1.22 upgrade
 into the router, y’all won’t have to hassle with a TFTP client again.  The V1.22 upgrade includes a Java-based upgrade page.

But, MacOs users who attempt to utilise the V1.22 firmware’s congenital in Java update page with Internet Explorer 5.0 or higher will probably find that it won’t piece of work.  Reader John Strung reports that you lot can go around this problem by usingApple’s Applet Runner to execute the Java applet instead of the IE5.0 Java engine. Here’southward what you do:

Annotation: You must accept V1.22 firmware or higher already loaded in the router in lodge to follow these instructions!

  1. If y’all don’t take the Applet Runner, download the MacOS Runtime for Coffee package.  Version 2.2 for MacOS 8.ane or higher is located

  2. Open the Applet Runner and unrestrict security settings in the Applet Runner’s preferences panel.

  3. Download and uncompress (using Stuffit Expander 5.0 or higher) the firmware.exe file from the Linksys FTP site.  (Yous might have to change the extension from .exe to .nix to get it to expand.)

  4. Motility the Code.BIN file in the expanded folder to the desktop.

  5. Blazon into the Location box in the Applet Runner.  (If yous changed the default accost of the router, change the192.168.1.1 to the address that you assigned to the router.)

  6. After the upgrade completes, remember to reboot your router and restore whatever special settings.


Updating Firmware with aLinux/Unix car

Here are the Linux/Unix commands to upgrade the router
(thanks to Jean-Christophe Hugly for the info!)


Notation:Y’all will demand to temporarily remove any admin countersign from the router before upgrading the firmware. (Linux tftp doesn’t embed the password in the tftp WRQ (write asking) parcel as the Linksys requires.)Restore the password later on you’ve completed the upgrade.

This assumes the Code.BIN file is in the electric current directory.

  • tftp <the fire wall IP Address>
  • fashion binary
  • put Lawmaking.BIN

Or instead of removing the countersign, you can try this command:

put Lawmaking.BIN Lawmaking.BINoctetpassword

wherepassword is replaced by your router’southward password.

(Cheers to Ben Galliart for this tip!)

Or you canpatch the Linux TFTP program.  You can download a patch from
 against tftp-0.sixteen-v.src.rpm, courtesy of January Vilhuber.



Updating Firmware with aOs/two automobile

(Thank you to Jean-Claude Desinor for the info!)

I have been using ane.35 with an OS/ii machine.

The process is the same as for Linux/Unix:

i) Temporarily remove the password through the Assistants Web Pages

2) Exit your WEb browser

3) Go to the directory where the lawmaking.bin file is located

four) Type “tftp router’s_address>” to outset tftp and connect with the router

five) Type “way binary” to become into binary mode
(If you want to see the packets being sent, type “verbose”)

6) Type “put code.bin” to upload the code

7) Blazon “quit” to go back to the control prompt.



Firmware upgrade tips

The post-obit tips may help you with the firmware upgrade procedure:

  • new_ani-8861420 Try thenew TFTP2 upgrade utility.
    Download from here

  • It’s a good thought to download a copy of the existing version of your firmware from the
    Linksys FTP site
    , so that you can restore information technology in example something goes wrong with the newer version of firmware that you are trying to load.  If you can’t observe your verbal version, simply download the latestreleased version.  If the Linksys FTP server is down, use the
    1.30 version from here
     (this is the entire ane.8MB self-extracting “.exe” file).

  • Does the upgrade plan successfully finish, merely you lot tin can’t bring up the Admin folio?

    Try backing off to the previous version of firmware and apply the“Advance” button on the Upgrade Firmware program and set it to sendFilename with path, and change theInitial delay to 1000ms.(Thanks to Timothy R. Davis for the tip.)

  • TheTFTP upgrade server is burned into the ROM of the router, and can’t exist erased.  If something goes incorrect with the upgrade and you become the dreaded steady “Diag” light on the router, only echo the upgrade.

  • If y’all are having a NIC connection problem, yous may accept an upgrade fail and not be able to resurrect the router.DON’T PANIC!!!

    Eitherconnect the router to another figurer with a different NIC, orconnect a hub between your computer and the router (don’t connect “Uplink” to “Uplink”, connect “Uplink to a NORMAL port), and retry the upgrade.

  • You might accept a problem upgrading or logging into the router if you utilise besidesstrong
    a countersign.
      Some versions of the firmware are reported to take bug with mixed upper & lower example letters, or with characters other than numbers and messages.  Some users accept been able to use their password successfully on the router, simply have it fail when trying to use the TFTP upgrade client.

    We recommend trying to use as potent a password as possible, but if y’all have problems, endeavor using a simpler password.  Y’all should also stay abroad from the characters “/” and “\” in your passwords, keep the length under 39 characters, andpractice non use any spaces in the password (your browser will interpret the space grapheme to ‘+’).

  • Some firmware versions reset the countersign to “admin”, then attempt that if your normal countersign doesn’t piece of work.

  • If you still take problems upgrading due to getting your password rejected,try entering a blank password, and so try the upgrade.  Be sure to restore your password subsequently y’all’ve successfully upgraded!

  • However can’t get the firmware to load?
    Come across this tip

  • Hither’s a copy of the installation instructions (Readme.doc) file that comes with the upgrade file:
