I just got s4 today, trying to sign into my wireless network every which way, i'm having no luck. When I unsecure the network, the phone connects, but i live in an apartment building; I can have my wifi all open. I tried everything, all my other devices work fine on the secured network except the s4
ditto..its actually snapping out some pretty decent wifi speeds compared to my last phone..with that being said though this phone is going back and i'll be changing up to the One..to many other issues im having with this phone to want to risk passing my 14 day marker.
There are compatibility issues with some routers. I had these problems with a Dlink DIR-655 router. After research on other sites indicated the incompatibilities I went out and bought a newer router. For you information, I got the Dlink DIR-836L and have no problems any more.
