Heb de v2 versie afgelopen zondag aangeschaft. Meteen WRT-DD erop gezet. Tot gister werkte draadloos heel goed maar sinds vannacht niet meer. Waar ik eerst full bereik had heb ik nu maar 1 blokje zeer slecht bereik. Factory reset gedaan maar helaas niet geholpen. Nu wil ik de netgear firmware erop gooien maar krijg een "De Upgrade is mislukt." melding.
Weet iemand hiervoor een oplossing?
Firmware opnieuw flashen via TFTP dan
First of all, You must download the file tftp.exe from:
http://www.tftp-server.com/tftp-download.html
(92 kB version - second link)
Second, download the file with WNDR3700_xxx.img original firmware from:
http://kb.netgear.com/app/answers/detail/a_id/12863
(ex.)
Place both files in the same directory ex. c:\WNDR
Than:
- plug the PC into LAN port 1
- set the pc to a static IP of 192.168.1.2
- power on the router
- press and hold the RESET button as soon as the switch LEDs light up.
- keep holding RESET until the power LED begins to flash orange and then green.
- only the power LED is flashing green (and of course port 1), release RESET and than
Run cmd on PC and go to c:\WNDR and type this code:
tftp -i -v 192.168.1.1 PUT <filename>
(replacing <filename> with your firmware image, of course.)
The TFTP transfer will happen VERY quickly. This is because the image is stored in RAM before flashing. Unless you can access the serial console, the router gives no indication it is now writing the image. What you can do is try to TFTP it again. If TFTP now fails, that's good, the router is busy flashing the image. If TFTP works, the router refused to flash the previous image.
After a good 5 minutes (or less), the power light will turn solid orange. The router should now be booting into the image.
