There are three networks to consider when talking about your router; WAN, LAN, and WLAN. WAN is the traffic coming to and from your router to the internet. LAN is the traffic around your private network. WLAN is the traffic coming from wireless devices to your LAN. So just like GF prioritizes different traffic from LAN to WAN, WISH prioritizes traffic from WLAN to LAN. The thing about prioritization is if there is no bottle neck to begin with, it only makes it worse. Think of putting a traffic light at a intersection with very little traffic, it just creates traffic. Now if you had like 10 wireless devices all connecting at once, and you started seeing your connection rates drop, then yea, WISH can help. Otherwise it will just, as most observe, slow down your wireless.
