Does the set up take time, Will it give me signal for my Netflix, YouTube and phone? My Netflix always lags and i can't watch anything without it loading for long periods of time. Would it give me just enough speed to watch a movie without lags?

It may or may not be the speed of your internet. If your Netflix lags and it’s close to your current device, the WiFi extender won’t do anything for a speed increase. You may want to look at upgrading your internet modem/router. Or contacting your local internet provider to determine your current speeds. Sometimes routers slow down your speed. I used to have a linksys router and it cut my speeds in half. Switched to an ASUS router and oh my god...download speeds were so fast! Check it out with your internet provider first. Or download Speedtest app to see your current actual speeds.
