Networking – WIFI: iPhone/iPad getting much slower bandwidth than laptop

I just got cable internet installed (Comcast). It claims that my down speed should be 25mbit. Over wifi, I get close to that on my laptop, but only about 8 on average with my iPhone/iPad.

I'm using testmy.net in the browser on all devices. I have an ARRIS / Motorola SurfBoard SB6141 DOCSIS 3.0 Cable Modem and a Medialink Wireless N Broadband Router. iPhone 5 and iPad 2.

I read somewhere that disabling WMM and the firewall on the router would help (is this even a safe idea?). I've tried both, and neither seem to make much of a difference, if any at all (sidebar: I've noticed that my download speeds vary wildly with cable internet… on my laptop, I'll get 12 down, then 22 five minutes later. Is this typical for cable internet?).

It's the Comcast router, don't change your Apple settings! Turn off your personal router. Using a pen, press the reset button on the top of the back of your Comcast box and hold for a FULL 30 slow count seconds. Let go and allow the router to reboot, say at least 5 minutes. Go watch TV for a while, don't rush this step! Come back and turn on your personal router. All fixed!
