Unbrick netgear WRG614v5

Hello, whilst updating my netgear WRG614v5 wireless router, my web browser crashed, and now my router doesn't work. Is there any way of flashing the firmware.  some of the guides i found confused me.

Thanks

Is the router still PINGable over LAN??

try pinging the router's known IP address from a host on the SAME subnet, and checking if TFTP is available on the router.

i tried to ping 192.186.1.1 which is the default ip address of the router. It tried using a static ip address as well, but that didnt help.

Static IP set up:

ip: 192.168.1.60
subnet: 225.255.255.0
gateway: 192.168.1.1

DNS: 192/168.1.1

have you ever changed the default router IP? if so, you should use that IP.

additionally, you may use -t parameter to PING the router continuously, turn off the router and wait for a while, then turn it on again to see if there is any responsible PING results while the router is booting up.
Your help has saved me hundreds of hours of internet surfing.

how do i change the router ip?
Darr247

Well, I can't find any documentation on a WRG614, so I'm going to presume you actually have a WGR614.

They have a recovery procedure on the website

http://support.netgear.com/ci/fattach/get/109/1311011828/redirect/1/filename/Firmware%20Recovery%20for%20Routers%20v1.1.pdf

Do you have the original CD that came with it?

That's required, because the router-specific firmware the recovery program accesses is on the CD, too.
Get the wgr614v5_1_0_9_1_0_6.chk firmware file while you're there, because if you have the CD you'll need it to upgrade to the latest after recovery, and if you don't have the CD you'll need it to 'put' it to the router with tftp if you get it to respond to pings.
Darr247

If you remember the router's IP, use that to try the pings.

While bricked it may not be possible to reset it. You can try a 30-30-30 Reset, but it's possible the reset button is ignored without a firmware routine to enable it.

I tried the 30-30-30 reset but it did not work, also i do not have the original disk.

When i ping the router using the command "ping -t -w 2 192.168.1.1", it it says "Request timed out", i also tried plugging it in and unplugging the router, but i got the same error message. occasionally when i unplug the router i would get the error message "general failure".

Hmmm...
you should be seeing something like

At that point you should plug it back in and continue watching for a response.

It might respond for only 3 seconds or so, within 20 seconds after you plug it back in, and when you see the first response you would immediately switch to the tftp client (which would already be setup, ready to start sending) and start the 'put'. Then go back to the command window and do Ctrl+C to stop the pings.

But if you can't get it to respond at all like that, you would need to disassemble it and try to find a place to connect a jtag cable, possibly having to solder in a serial port header (if there's even a provision on the router's motherboard for such a header).

You don't recall ever changing the router's LAN address from the default 192.168.1.1, right?

there is no 192.168.1.1 in your ARP -A, that means the router is not connected at all.

if there is a 192.168.1.1 line there, that means the router is connected but not responding for PING.

i have the router connected to the computer. does this mean that the router doesn't assign itself an IP address when it boots?

i think so, as bricked. :(

i guess Darr247 may share some hints to unbrick the router by short-circuiting a few pins on the motherboard... i did once for my Linksys router.
Darr247

No; do not short pins.

Here's a procedure for making your own JTAG connection
http://www.myopenrouter.com/article/10341/Recover-Your-WGR614L-Using-a-Serial-Console-Windows/

If you take it apart and your WGR614v5 board looks just like those pictures, that procedure should work.

Here's a source for the cable they say is no longer available from Mouser
http://www.amazon.com/dp/B004LBXO2A
I would also get a set of these connectors
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=180878451107
and clip off 3 of those pins from one of the connectors, to  insert in the #2, #5 and #6 holes of that cable's plug, then have someone just hold the pins in contact while you follow the putty/tftp directions. Unless you're very proficient at soldering.
Darr247

Or, you could watch for another WGR614v5 with the CD on ebay, craigslist, et al, and hope the recovery program on the CD could fix it.
