Multi-WAN & Failover

For When Your Internet Simply Cannot Go Down

Card readers offline. Phones dead. Cameras dark. For some businesses — and some households — a dropped connection isn’t an inconvenience, it’s an emergency. That’s what multi-WAN is for.

We combine your primary provider with a second (or third) independent connection — Starlink, T‑Mobile 5G, or other wireless solutions, complete with outdoor modems and antennas for solid signal — and configure automatic failover. When one connection drops, the next takes over in seconds. Available for businesses and homes, statewide.

Common Questions

Business Services FAQs

Can you fix Wi-Fi dead zones in my office or home?

Yes — that's one of our most common calls. We design Wi-Fi coverage properly using professionally placed access points, not a pile of range extenders, so you get fast, seamless coverage everywhere. Businesses and homes alike, statewide.

Do you install network cabling?

Yes. Smaller runs we handle ourselves; for larger structured-cabling jobs we bring in our cabling partners throughout the state — crews who know us and work with us regularly — and we manage the whole project, so you still make one call and deal with one accountable local team. Every run is clean, labeled, and tested.

Can we keep our existing business phone number?

Yes. We handle number porting so your existing numbers move to the new phone system with no interruption. Your customers never notice the switch — except that the experience gets better.

What does IT support for a small business include?

Whatever your business needs to run: workstation setup, email and Microsoft 365, backups, network security, printer and point-of-sale headaches, vendor wrangling, and fast help when something breaks — including computer and device repair for your team.

Do we need a contract, or can we call as needed?

Both work. Some clients keep us on for ongoing support; others call when something comes up. As you grow, we'll recommend the arrangement that actually fits — not the biggest one we can sell.

What is AI detection on security cameras and why does it matter?

Instead of alerting on every branch moving in the wind, AI detection recognizes people and vehicles — so you get a notification when someone approaches the building at 2am, not 400 false alarms a night. And with our systems, you own the footage — no forced cloud subscriptions.

What if our internet absolutely cannot go down?

That's what multi-WAN failover is for. We combine your primary provider with a second independent connection — Starlink, T-Mobile 5G, or other wireless solutions, complete with outdoor modems and antennas — and when one drops, the other takes over automatically in seconds. We build these for businesses with critical connectivity needs and for homes, statewide.

How fast can you respond when something is down?

Call-taking hours are Monday–Friday 8–5, and small businesses with a critical issue can leave a message 24/7 — we'll get in touch ASAP. Being mobile and local means we can often be onsite the same day.
