I'm getting 50/5 speeds via ethernet, and 4/2 barely via WiFi. What could be causing this problem? I've run wifi speed test via my iPhone and 2011 Macbook Pro. I have a Linksys E1200 router V2 with the most updated firmware. I'm sitting 3 feet from my wireless router, with all other devices turned off. On a normal night, my family will be streaming video on the Apple TV and have a couple macbooks running, and possibly an iPad. Anyone have an idea of what might be wrong with the WiFi? What settings can I mess with?
