Whole-Home Wi-Fi & Network Solutions
Eliminate slow speeds, buffering, and Wi-Fi dead zones with professionally designed whole-home Wi-Fi and network solutions built for modern luxury residences and demanding commercial environments. Today’s properties rely on robust connectivity to support smart home automation, home theater systems, 4K and 8K streaming, video conferencing, security camera systems, automation platforms, and remote work without interruption.
At Audio Video Long Island, we provide whole-home Wi-Fi installation and professional network design for residences and commercial properties throughout Nassau County and Suffolk County, including high-end homes in Roslyn, Brookville, Old Westbury, and surrounding North Shore communities.
Enterprise-Grade Wi-Fi & Network Infrastructure
We deploy enterprise-grade networking hardware and advanced mesh Wi-Fi systems to create reliable, scalable network infrastructures. Our solutions are built using professional platforms such as Ubiquiti UniFi network systems, allowing precise control, monitoring, and optimization of wireless performance throughout the property.
These systems ensure every connected device, from smart TVs and media rooms to automation controllers, access points, security cameras, and IoT devices, receives a strong, consistent signal with minimal latency. This level of performance is especially critical in large estates, new construction homes, and commercial facilities across Long Island and the greater New York area.
Professional Site Assessment & Network Planning
Exceptional Wi-Fi performance begins with proper engineering. We conduct a comprehensive technology site assessment that evaluates floor plans, square footage, construction materials, interference sources, and device density.
For properties in areas such as Great Neck, Manhasset, and Glen Cove, where larger homes and complex construction are common, this planning phase is critical. Based on our analysis, we strategically deploy wired and wireless access points to eliminate dead zones, balance network load, and ensure seamless coverage indoors and outdoors. UniFi access points are positioned for optimal performance, while structured cabling solutions and professional switching infrastructure provide the backbone for long-term reliability and future expansion.
Secure, Smart, and Segmented Networks
Performance alone is not enough. Security is essential. We implement advanced firewall protection and network security using platforms such as SonicWall firewalls, delivering enterprise-level threat protection for residential and commercial environments.
Our security approach includes firewall configuration and intrusion prevention, encrypted network traffic, network segmentation for smart home systems, AV and security devices, and secure guest Wi-Fi networks isolated from core systems. This layered design is ideal for luxury homes, offices, and mixed-use properties throughout Long Island where privacy and reliability are non-negotiable.
Scalable Networks Built for the Future
Our Wi-Fi and network solutions are designed to grow with your technology needs. As new smart home systems, home automation platforms, commercial AV systems, or business applications are added, the network can expand without replacing the existing infrastructure.
This future-ready approach is especially valuable for clients in fast-growing areas across Nassau and Suffolk County, where homes and businesses often evolve with new construction phases, renovations, or technology upgrades.
Reliable Connectivity Without Compromise
Whether supporting a fully automated luxury smart home, a waterfront estate, or a professional commercial AV and IT environment, our networks are engineered for speed, consistency, and long-term reliability. Clean installation, thoughtful system design, and ongoing network support and maintenance ensure dependable performance day after day.
Audio Video Long Island is trusted for whole-home Wi-Fi installation, UniFi network deployment, SonicWall firewall integration, and secure, high-performance connectivity solutions throughout Long Island and the greater New York region.

We make digital safety a top priority alongside performance.

As you add new smart TVs, security systems, smart appliances, or expand your business operations, your network needs to be ready to handle the increased demand.

I recently had Audio Video Long Island come in to completely upgrade our home’s tech and entertainment system, and the experience was amazing from start to finish. Their team installed a beautiful custom TV wall, clean wire-free media setups, smart thermostats, and a wall-mounted iPad control station. Everything in our home TVs, audio, lighting, thermostats, and more is now fully automated and controlled through one simple app. Every install looks sleek, modern, and seamless, and you can tell they take pride in making the home look elevated, not cluttered. The attention to detail is unmatched straight lines, perfect placement, hidden wiring, and super clean finishes. Having everything in one app has made life so much easier. No more juggling remotes or apps I can adjust the temperature, turn on the TV, switch the audio, or check cameras all from one place. If you want a luxury quality smart home setup that’s done right the first time, Audio Video Long Island is the company to call.

We couldn’t be happier with the full AV and security setup for our bar. We hired this team to handle everything for our new bar — projector and TV installations, a multi-zone professional audio system, POS setup, alarm system, and all the security cameras throughout the space. They took care of the entire build from start to finish, and the results are incredible. The TVs and projector look amazing, the audio is crystal clear in every zone, and our POS runs flawlessly. The security system gives us full coverage and peace of mind, and the whole network is fast and reliable. They really knew how to design the space to match our needs and kept everything clean and organized. If you’re opening a bar or upgrading your setup, this is the team you want.
