You note that your monitor is inches away from the router, which reminds me of this post:

I just learned (from a Support reply) that the Sense monitor may go off-line if the WiFi signal is too strong! The recommended range is -30 to -70 (dbm); the support staff looked at issues I was having and reported that my WiFi signal strength was often -27 … and that the WiFi chip can get over-saturated and take the monitor off-line.

You also said you directly plugged it in, which should resolve the issue if the above were a problem. In any case, opening a support ticket is a good place to start.
