N750 WNDR4000 big issue
Hi all, I'm french but I'll write in english, so excuse me if my english is not so good. I had an issue with my router, it was only delivering APIPA on LAN and cannot register to my internet...

Welcome to NETGEAR Community!
Try using TFTP in reverting the Netgear firmware.

If TFTP still fails, most likely the router is dead.

TFTP isn't the easiest thing to get right.
This doesn't offer much in the way of clues.

We don't know what you did to get there.
If a standard factory reset fails, there is more severe, recovery reset, that you could try:
- Press reset for 30 seconds
- Keep pressing reset while removing power
- Keep pressing reset for another 30 seconds while apply power
If you are forced to use TFTP try a web search for videos that guide you through the process.

Different device, but the approach is the same.- CorlyJun 01, 2021Aspirant
Thank you for the tips but I already knows how to use tftp.
I'm a Sys & Network admin so I uses tftp and routers through my job
The issue was the router cannot get an IP from my internet router, who delivers correct IP to others equipments.
And, without WAN, the Netgear router did not deliver correct IP, even with the DHCP correctly configured.
So I tried to upgrade the firmware : nothing better.
I tried to downgrade : same
I tried to put DD-DWRT : same
so I wanted to come back to the original firmware and power led started to blink
I already tried the 30/30/30 reset, and tftp doesn't work (server unreachable)
I think ther's nothing else to try, I thought it may exist another way to upload a firmware but I understood tftp was the last chance..
So, the router seems to be dead, I will see to buy another one ;)
thank you all for your help
