I have two CCAs here with zero issues at all. And I'm using crappy Linksys consumer-grade routers loaded with DD-WRT. The CCAs play in perfect sync here with no dropouts, and one is a bit of a distance away. Doesn't matter if I cast with computer, phone, tablet, etc., they just work. Definitely the router is a problem if there are dropouts, or a weak signal. Remember that interference from neighbors (other WiFi traffic) can still wreak havoc even though you may show a strong signal in the house. And there are definitely pockets of good and bad reception even just several feet from a WAP (wireless access point) in the same room, as I've noticed with a signal strength meter. For other reasons, I am going with a pro-level WAP in a few weeks. It's not inexpensive but I just want to do the job correctly from here on out.
