Band-steering directs clients to 5GHz to get them off of the 2.4GHz which is usually cluttered by IoT devices and microwave ovens. :P If using 5GHz helps, that's a faster band anyway, and shorter range. I've had good luck with it and use it on my laptops and phones and leave my cameras and IoT stuff on the 2.4. Glad it's all going better for you!
