Hi

I can't flash the firmware on a Netgear VEVG2500.

I red carefully all the information on the peacock thread.

I use tftp.exe on windows 10 and disabled all antivirus, firewall and connections except the LAN.

I get the error message "Unable to get responses from the server" all the time.

I assigned a static IP to my computer. I can ping the router.

According to the ping -t command, TTL is always 64, never 100 or 128 even immediately after a 30-30-30 reset or after pluging back the power. Is it normal?

I leaved the password field blank, but when I enter a wrong password, I get no authentification error.

This router is a ISP branded unit but flashing the firmware is still posssible: some open source firmware are available on Netgear's website especially for this product: http://kb.netgear.com/2649/NETGEAR-Open-Source-Code-for-Programmers-GPL?cid=wmt_netgear_organic

here's its datasheet: http://www.dsl-cable.net/site/doc/dsl/numericable-fr/netgear-vevg2500-spec-tech-const.pdf

Some help would be much appreciated... thanks!

server need to be 192.168.0.100 (by default)
tftpd32 works well for me.

Can you post a small wiki on how you manually launched tftp and managed to flash the router? I'm having the same problem
