I was looking through the BBQGuru website and noticed that they have a new version of their firmware. When I bought mine, late 2013, it had v1.2...they are up to v1.7.
I installed it and it is working way better than v1.5. Now it can scan available networks and you can select the network you want to join.
It was pretty easy to install the new version, but hit me up if you have questions.
