What is WiFi speed. I use an android device.
What internet service do you have? I use the Speedcheck app on my Droid Turbo 2 phone to see my speed when connected WiFi to my Comcast internet service at home. On my desktop, hardwired to my router, using speedtest.xfinity.com, I get about 170 Mbps download and 6 Mbps upload. On my Droid Turbo 2, connected WiFi to my router, I get about 33 Mbps download and 6 Mbps upload.
wi-fi saves using data but can be risky if unsecured, public wi-fi.
