FurryNutz,
Thanks for the reply.
I am located in Canada, is there another forum for regional specific questions ?
I have contacted support over email and they kind of dodged WPS question and pointed out that I can use parental control as a mac filter (but the firmware is so "watered down" that you can't directly edit parental control device list, you need to wait for a device to infiltrate your network, get allocated an IP and appear under the "connected devices" then you can filter it out).
I hope they have WPS disabled in the firmware but unfortunately its not the case, as the WPS code is stickered right at the bottom of the router and I verified its enabled using a WPS scanner app on my phone.
Yeah I know about DDWRT, but since I just got the router I thought its a little bit early to void my warranty going 3rd party

I will follow up with support and let you guys know how it ends up.
