Suddenly my router has stopped responding to my systems. All the systems are installed with windows 10 professional operating system. And the details for my router are Netgear technical support
You’d probably have to contact Netgear. Not much Emlid or Emlid users can do generally.
If you look around on the forums here you will find you are not alone. Recent firmware versions have all been crap with issues like you describe. Some don’t get a week before having to take action vacuum. There are some that say one of the older, prior to the security fixes, works.
