Who I have the same questioned this topic

I have had a Samsung network extender for several years. It has always worked fine. A week ago it stopped working, the Sys light flashes red and the GPS light stays solid red. Nothing was done or changed to the unit or computer. It appears like it can't find a GPS signal. I have checked all connections, the GPS antennae and cord and everything seems fine. It sits in a very large window with completely clear access to the sky. This is the same place it has been for years with absolutely no issues. I live in zip 98250. Any suggestions?

Thanks!
