CyberWRT для роутеров на CPU RT5350

[ssp]

This is the exact device I have (KY928A). Ordered 3 of these and have installed on my network for guesthouse/hotel rooms. With default firmware, the devices send bad broadcast traffic and respond to each other using unknown protocol and completely flood the network with broadcast storm. Need to replace the firmware with cyberwrt. How can I do this? Any help will be appreciated.
