Attempted to setup my laptop as a WiFi access point with no success. The laptop is running Lubuntu 15. In an effort to not waste more time on fiddling with Hostapd and other Linux packages, I just ordered from Newegg.com a $17 WiFi-N router that runs OpenWRT. It should be here in a few days. This should clear up any possible bottlenecks due to running the WiFi network from a RPi.
