I would not have the firewall/router/WAP on a shelf in the kitchen but in a more convenient location within the house.
The PC which i use far more than any other device is in the kitchen (by far the biggest room in out small house) the PC has wireless built in but i have always used Ethernet for the higher speeds we have laminate floor so i don't really want to pull it up my DIY skills are not the best, i may just bite the bullet and go for the 500 package as if my understanding of this is right the huge jump in speed would guarantee our Wi-fi speeds are much higher than what we are getting now or would get on the 150 package.
