Chromecast is a handy device that gives smart TV capabilities to your standard TV.Īlthough Chromecast has a lot of great features, it mainly relies on your wireless network for streaming videos which can cause problems, especially if your home network is not that fast. If you are among these users, there is a chance that you use Chromecast to watch your favorite movie or series on various streaming platforms.

While the latest televisions today have Netflix and other applications built-in, there are still users who own a TV that was released a couple of years back. This should significantly improve performance.Can’t stream videos using Chromecast properly due to random lagging? It uses peer-to-peer airplay, which means that it connects to your laptop directly via bluetooth and wifi, completely cutting out your router as the middleman. The next best solution would be to get a 2013 Apple TV. See if you can trouble the issue by either using a different router (a cheap TP-link router can be had for $20?) or mirroring another device like your iPhone or iPad and see if there is any lag streaming videos and stuff. All I can say is that the issue is either with your laptop or your router. I use an asus router at home with my 2012 ATV and airplay quality has been pretty stable. If you are just watching movies, you may want to try just airplaying the video rather than mirroring everything, which takes up way more resources. Rather, your Apple TV is constantly decoding the compressed signals from your MBP through and from your router, and this doesn't require any internet connection at all. I can be mirroring content through a router with a 1mbps dongle sticking out of it and quality can still be excellent if the wifi signal is strong enough. The quality of airplay mirroring has nothing to do with your internet speed.
