AFAIK, the password you set in QuickSet, you'll find it in Webfig, under Wireless/Security Profiles, as WPA/WPA2 preshared keys.
You can check that is the same password by un-pressing the Hide Passwords button on the left-side menu
Ok, good point for verification. Thx.
.
But it would be better to use WinBox and to switch from using QuickSet to configuring in-depth your router.
As I'm a Linux user and since Winbox is a Windows application, I prefer the web interface (Webfig).
Of course I could try to run the Windows EXE Winbox under the WINE environment in Linux,
but I think there is no need for this as there is the Webfig avail.

Depending on your Samsung phone, it may be the case that you need to better setup your Wifi networks, to see better speeds.
The community here might be able to help after looking @ your current setup. You can post it here (using CODE display to see it better):
To do that, go to New Terminal and input these 2 commands:
/interface wireless
export hide-sensitive file=anynameyouwish
Ok, here is the export. Can it be improved to get higher wireless speed?
