The window for installing firmware via TFTP is very short, just a few seconds. The follow technique may help.
- Open two Command Prompts.
- In one window, start a ping -n 1000 192.168.1.1.
- In the second window, prepare but do not execute the tftp command (e.g. tftp -i 192.168.1.1 firmware.bin).
- Unplug the R7000, wait a few seconds, then plug it back in.
- The pings in the other window will fail and then start to work.
- As soon as the pings start working, start the tftp command.
