Mikrotik mAP lite as a commissioning tool

Good afternoon!

I was wondering if anybody else had tried setting up one of these little access points as a part of their tool kit for when they need quick wireless access to an ETC Network for troubleshooting, testing, etc.  MikroTik mAP lite

I'm having a bit of trouble figuring out how to get it set up.  The manual is helpful but a little hard to read, and the webUI isn't the best at describing which options do what.  As I'm not exactly a networking expert, I'm a little lost in all the vocabulary.
