Is the advice in this thread still solid?
I've been having problems getting WiFi on my iPhone in my house for a year now (strangely, no problem from my iPad - my iPhone is a 4s, my iPad is current generation).
I think, as an intuitive guess, it is my shitty old Netgear Rangemax Wireless Router.
Now, I just got my Roku box, and sure enough, even though it is in the next room from the router, it is randomly dropping connection, 50% of the time says that a network is unavailable, etc. Pretty much comparable with my experience on my iPhone (and my attempts to stream video in the past on other devices).
So I'm going to try a new router, but I don't know what to get.
