That's a feature of some routers. However you may cause Netflix to get laggy.
Did you optimize your network? Such as wire up the Netflix connection (WiFi is shared!) and try the DNS 18.104.22.168?
Ok so I have decent internet it runs fine when I'm only one using it. But I have family who like to watch Netflix but when they I can't do anything on my laptop it's very laggy. Is there any way I can prioritize to where I get most of the Internet to my computer?
