Problem with wn2000RPTv3 firmware update

Hello everyone,

I have a problem with my Netgear wifi extender. It a WN2000RPTv3.

I was trying to update its firmware but i didn't know that i had to be connected with ethernet and not with wireless to it... So, i tried in wireless.

Now my extender has a blink light green and when i try to connect it to my pc with ethernet, my pc don't recognize it.

I don't know what to do. I tried to reset it but the green light persist.

I read on internet that i may try to update its firmware using a tftp2.exe but i don't know how.

Someone can help me?

the symbol that blinks is the status light

Thanks in advance and sorry if my english is not perfect
