I have a suggestion. I was in a support chat today and support noticed my wifi sucks in my basement. Yep, I know. Even though my router is one floor directly above the Grobo, the EM interference with all my other computers and being slightly underground degrades the Grobo wifi signal. It was suggested that I buy a wifi extender, and I’ll happily do that.
My suggestion: everything else in my basement is hardwired via a switch that is also hard wired to my router from CAT5 run in my home’s walls. It’d be great if your arduino board had a hard ethernet port. I could directly plug it in via CAT5 and boom, networking issues resolved.
