Systems and methods for guaranteeing end-to-end QoS for wireless connections over a cable network are disclosed. Provisioning of on-demand guaranteed bandwidth connection over a cable network uses mechanisms from DOCSIS domain and Wi-Fi domain. A multi-domain orchestrator is implemented to control both domains. A bandwidth request is received from a client device connecting to a network service provider access point. The bandwidth request is updated for both domains with results of speed test of the wireless link if the speed test results are lower than the bandwidth request. The orchestrator and client device negotiate the bandwidth request using a three-way handshake over PacketCable Multimedia (PCMM) protocol. If the available bandwidth on either the DOCSIS or wireless link is less than the bandwidth request, the orchestrator generates a new bandwidth offer. If the client device accepts the offer, the orchestrator configures the DOCSIS and wireless links using their respective domain protocols to provision the connection with guaranteed end-to-end bandwidth.
