Because there probably is no "new dealer", this story doesn't make sense. He's either a homeowner who somehow got Composer on his computer and is trying to go around the entire C4 dealer system and not pay anyone who is actually authorized to open up the software. Or he's an ex-employee of a Control4 dealer pretending to be the "homeowner" to drum up some sympathy. Still has Composer on his computer but no real dealer login anymore, and he hit a road block and can't perform the work he promised. If the "new dealer" calls in surely they would transfer the license, even if there was a small fee, why wouldn't they?

100%

But you didn't buy the driver from Blackwire, the dealer did, right? This is like showing up at Target with a receipt from Walmart and asking for a refund on something somebody else bought. I see your point of view but if you are not a Control4 dealer, employee of a dealer, employee of Control4, etc, you shouldn't have access to Composer or any drivers, pretty sure that's a violation of the dealer agreement

I would not use Load Balancing, the Ruckus reps do not recommend it unfortunately, and if you insist on having 2.4 at full blast everywhere to support 2.4-only IoT devices in every zone you are kind of out of luck as far as co-channel interference within your LAN zone. I would just set your signal strength to auto on both bands, set 2.4 to Background Scanning, set 5 GHz to ChannelFly, and things will stabilize over time. If you are not able to use 802.11ac for some reason, a legacy 802.11b device could be over-contending for the medium and causing a ton of retransmissions. This could also be caused by poor SNRs and environmental interference, forcing all clients to bump down their PHY and MCS index further down the table. Or even just from your overall network design and congestion, especially if the WAPs are not on the Core switch or you have streaming devices 2-3 switches away from the router. Regardless, your network-wide overhead from creating another 802.11b only wifi network would exceed any performance hit taken from a single legacy device. Under Clients, go to Show Details and let us know, what is the RSSI, SNR, and MCS info (at the very bottom) for some of the clients you would expect to be using 802.11ac?
