Needing some help with Internet Speeds (sorry if wrong category)

[ILikeRTS]

So for some odd reason, all the laptops in my house don't load webpages quickly. Phones and other handhelds work fine, and ethernet connected desktops do too, but laptops and everything else are unbearable.

I was wondering if this is either:
a) a problem with my laptops
b) router needing upgrading (its fairly a new Asus RT-AC56R Dual Band)
c) Internet service needing an upgrade
d) other (meaning what ever you guys can deduce, if you are willing to help)

Do other wireless devices work fine at full speed? If so, does the laptop get faster speeds when plugged in via ethernet? Also, does it gain speed if you move it next to the router? It could be something as simple as a power saving feature, does the laptop gain speed when it is plugged in instead of running on the battery?
