Firmware update failed - router not working now

Greetings,

bjtjaden 

Both antinode  and michaelkenward have provided excellent information.

Please post the TFTP command you are running.  Please complete with the information applicable to your environment.

tftp -i [router IP] put [firmware filename].[file format].

Besides proper execution, TFTP reflash also depends on timing.  There is only an extremely brief window of opportunity after the router has been statrted when the TFTP command must be executed.  If you miss this, you have to start over.

To familiarize yourself with this "window" open a command promt and type

>ping [IP Address of Router] -t

then press enter

What you will see... 

A continious list of ping requests to the router...   they should show fail

Now restart the router, paying attention to the winodw.  fail, fail, fail....  reply, reply, reply...  fail, fail, fail..

It is during that brief moment (reply) when you must press enter and execute the TFTP command.  It might be helpful to have 2 command prompt windows open...  having the second one with the command poised to "go" when you press enter.

Let us know if this helps.

I have tried your solution but when I do the actaul TFTP command - I get the error message:  "Timeout occurred - Connect request failed".

Is that the actual error message?

As shadowsports says the exact details are important.

One common issue is that people do not put the firmware that they are trying to write to the router in a directory where TFTP can see it.

In the folder where you are running things like "ping", do a "dir".

dir:

If you don't see the firmware, then it won't work unless you feed the path into the "put" command that shadowsports described.

In other words, the [firmware filename].[file format]

can also include the path to get at the firmware:

[path]\[firmware filename].[file format]

but it is easiest simply to copy the firmware to the folder you are working in.

Windows will usually put you in the current user directory:

C:\Users\[username]>
