How to fix this problem? What is the command for restoring these cookies back?

Hello,
The cookie contains vital information about your router including some very specific hardware settings, base MAC address and other data. Unfortunately, there is no command to replace it automatically, rather it has to be refilled with sensible data again.
It would be the best to find another working 1711 router and take its cookie value as an template. The MAC address would need to be located in the cookie and replaced with new unique value and then restored into the failed router. There is a procedure to do it from the ROMMON but I would rather not talk about it right now as it would be possible to "brick" your router completely. However, please do try to obtain the cookie from another working 1711 router. WIthout it, it may be impossible to recover your router.
Best regards,
Peter

Be advised thar even with the correct programming information, the hardware itself can be faulyt, and nothing can be done to restore it.
