1. Restart your router. Just take out the power plug, wait 10 seconds and put it back in. This resets your router and will make your home network faster and more stable. Why this works? Routers are in essence little computers, with software. Software will have small memory leaks and some processes will stop working correctly over time. That’s why it is a good idea to reset your router once in a while. Our recommendation: once a week.
2. Put your iPhone or iPad and your TV on the same router channel. Some routers (dual band) have create both a 2.4Ghz and a 5Ghz wireless network. For the best performance, put your iPhone/iPad and your TV on the same network. Preferably the 5Ghz network. But definitely not the iPhone/iPad on 5Ghz and the TV on 2.4Ghz, because that will negatively impact the performance of screen mirroring.
3. Use an AC router. Newer routers support Wifi AC. Older routers might only have Wifi B and/or G and/or N. B, G and N are not really up to scratch anymore for modern networking tasks, so go for an AC router. If your router supports AC also make sure that your router is set to use either the Wifi AC networking.
