Not sure exactly when this became a problem, but it's been happening at least the last couple of months. I think it started when I switched my router to a TP-LINK Archer C7.
Sometimes it will say PC available locally at first, but then will switch to saying available remotely or even not available at all. I can usually manage to connect but it's slow, get resolving connection messages, etc.
Are there some router settings that would fix this? Or maybe totally unrelated to the router?
Any thoughts greatly appreciated.
