Hello,

I'm having trouble updating my router to the latest version. It seems to me that it doesn't want to write the latest firmware for some reason.

I am currently running v24-sp2 (04/18/14) std - build 23919 and i have reset the router to defaults.

I have tried using the web update page, which simply stalls and does nothing.

Updating via ssh I get disconnected when I write the firmware, and then nothing happens:
Code:
root@49voor:/tmp# write wndr3700v4-webflash.bin linux
Connection to 192.168.178.4 closed by remote host.
Connection to 192.168.178.4 closed.


Using tftp I get a "transfer timed out":
Code:
tftp> connect 192.167.178.4
tftp> binary
tftp> rexmt 1
tftp> timeout 60
tftp> put wndr3700v4-webflash.bin
Transfer timed out.
tftp> status
Connected to 192.167.178.4.
Mode: octet Verbose: off Tracing: off
Rexmt-interval: 1 seconds, Max-timeout: 60 seconds



I enable syslogging, but none of the options logs anything.

Does anyone know what could be wrong?

Thanks!
Feday.

Reset the router and install thru GUI
Restart your PC and clear browser cache.
----
Connection to 192.168.178.4
tftp> connect 192.167.178.4

These IPs are definitely not from a WNDR3700v4 that has been reset to dd-wrt defaults ?????

I had to enter some basics to at least get my network back up and running. No internet is no fun Smile

This afternoon I did a 30/30/30 reset and tried using the webupdate again. Sadly I got the same issue and simply nothing happened.

What could this be? Question

I think 23919 is one of them weird builds but anyways ¬
On the WNDR3700v4
If you have a live WAN connection -
telnet in
Code:
cd /tmp
wget http://mrjcd.com/omg/WNDR3700v4/29519_wndr3700v4-webflash.bin
write 29519_wndr3700v4-webflash.bin linux
reboot

You can copy text if you want .. just hit enter after each line
e.g. --
'23919-29519-27858_NOTES.txt'

Just as a note 23919 does works as CB on the 5GHz. Speeds comparable to 29519.
27858 is fastest CB on 5GHz for me on the WNDR3700v4......

Or else -- If you don't have a live WAN or can't get one but can still telnet to router then -
With nothing connected but your computer to router via ethernet cable -
telnet in
Code:
erase nvram
erase linux
reboot

this will delete the firmware -- you will have to TFTP!!!
You should now have the flashy power light....but - you need to power-cycle
router
giving it at least 10 seconds off. Should reboot back to flashy power light.

You need to set a static IP on your computer (192.168.1.x --- greater than the 1 node)
Use your favorite TFTP client to TFTP new firmware to 192.168.1.1
I would recommend a netgear firmware so you can check that all is working ok. If you don't
have original netgear FW it let me know.... I have a few versions.
You can then install dd-wrt starting with a factory.img (the 23503-wndr3700v4-factory.img always works
for this ... you also should read wiki on the wndr3700v4) You can go staright back to dd-wrt but you
really should use the 23503-wndr3700v4-factory.img to do this... if you do, be patient because it
takes the wndr3700v4 a long while to fully boot up.
good luck -

Wooh! I got the router updated. Somehow doing the wget and write over telnet did work, where ssh just kicked my out.

Here's to hoping the version I've got on there now is stable!

The 29519(04/25/16) seems to be a good build for the wndr3700v4.
Glad to hear you got it going ---
