Introduction

Ever had a great day on site derailed by a homeowner shouting, “The Wi‑Fi’s down!”? It’s common now. Families stream, work, and secure their homes over the internet. When you pull a breaker, bump a router, or dust out an ONT, you’re not just cutting power—you’re knocking out someone’s work meeting. This guide shows why dropouts happen, how to prevent them, and exactly what to say in your proposal so you don’t eat blame, time, or margin. We’ll keep it practical: quick fixes, planned outages, and a tight handover so everyone stays calm and productive.

Key Takeaways

• In general, weekday occupied-home jobs often have someone working from home; a 5–10 minute network check can prevent callbacks and tense conversations.
• Commonly, adding clear outage windows and assumptions to your proposal reduces back-and-forth by about half.
• Many contractors find a small UPS on the router/ONT keeps internet up through planned short power cuts, avoiding most Wi‑Fi complaints.
• A simple before/after connectivity check (and a photo) at handover commonly saves 30–60 minutes of follow-up.

The Internet Dropout Problem in Occupied Homes

Why It Happens on Jobsites

• You shut off a circuit for safe work; the router or ONT was on it.
• Someone moved a mesh node to make space; coverage drops in the work area.
• Dust or heat builds around networking gear; it overheats and crashes.
• A ladder, vacuum, or tool pulls on low‑voltage fiber/Ethernet—loose plug, no internet.

In general, contractors report that 20–40% of weekday service or interior jobs now bump into internet complaints at least once during the day. That’s not because you broke anything—it’s because home networks are fragile and scattered.

Why It Matters

• Lost time: Commonly, a single dropout can cost 20–30 minutes of troubleshooting.
• Client trust: When kids can’t attend online class or a parent drops from a meeting, emotions spike.
• Reviews and referrals: It’s common for minor disruptions to spiral into refunds if expectations weren’t set.

Quick Fixes You Can Implement Today

Five-Minute Network Walkthrough (Before Work Starts)

1. Ask: “Where’s your internet coming in? Where’s the router? Any mesh pods?”
2. Locate the router and ONT/cable modem. Check power strips and extension leads.
3. Identify what circuit feeds them (quick outlet test helps). Note any obvious trip hazards.
4. Snap a quick photo (for your records) and confirm with the client: “If this outlet loses power, your internet will drop.”

In general, this 5–10 minute check commonly saves 30–60 minutes of later troubleshooting.

Minimal Kit That Pays for Itself

• Outlet tester and non‑contact voltage tester
• Low‑dust covers or a plastic tote for gear in dusty rooms
• Short Ethernet patch lead and spare power strip
• Compact UPS (600–1000 VA) for router/ONT in sensitive homes

Fast Triage If Wi‑Fi Drops

• Check power first (router lights on?).
• Verify cabling seated (ONT to router fiber/Ethernet).
• Reboot sequence: modem/ONT first, then router (wait 2–3 minutes each).
• If ISP issues: note time, lights, and advise client to call their provider.

Plan and Communicate Outages

Set Expectations Before You Start

In general, 1 out of 3 interior electrical or plumbing jobs needs at least one 15–30 minute planned shutdown. Tell the client early, put it in writing, and give a window.

Suggested language you can adapt:

• “We’ll need a 20–30 minute power‑off window between 10:00–12:00. Internet may drop during that time.”
• “If you work from home, please plan a hotspot or schedule calls outside this window.”
• “We’ll confirm internet is restored before we leave.”

Commonly, putting these 2–3 sentences in your proposal assumptions reduces back‑and‑forth by half.

Use Donizo to Lock It In

Speak it once, send it fast. With Donizo, you can capture these notes on site with voice, generate a clean proposal PDF, send it by email with client portal access, and get a legally binding e‑signature. Many contractors find this “say it → send it → signed” flow cuts approval time to same‑day on small jobs.

• Free plan: unlimited proposals with voice/text/photo input and e‑signature (PDFs carry a watermark).
• Paid plans: add custom branding on PDFs, invoicing and payment tracking once accepted, templates, and more.

Keep Internet Alive During Short Power Cuts

Practical Options

• UPS on Router/ONT: A 600–1000 VA unit commonly keeps gear online 30–90 minutes.
• Temporary Reroute: If your work circuit feeds the router, plug the router into a different live circuit using a safe, tidy extension.
• Phased Shutdown: Kill only the breaker you need, not the main, when safe and permitted.

Safety and Compliance Notes

• Avoid any backfeeding risks with generators. Use listed equipment and follow local code.
• Keep low‑voltage fiber and Ethernet away from sharp bends and crush points.
• Don’t enclose hot routers; maintain airflow to prevent thermal shutdowns.

Example: Panel Work Without Panic

Problem: Panel replacement requires a full‑day power off.

Solution:

• Day before: install a UPS for the router and ONT in a cool, protected spot.
• Confirm the ISP line and router location are away from the work area.
• Provide the client with a realistic no‑power window (e.g., 9–3) and remind them to hotspot.
• Handover: verify internet back up; document with a simple speed test.

Outcome: Many contractors report that this approach avoids mid‑day conflicts and review drama, even on long outages.

Prevent Accidental Disconnects on Site

Situations and Fixes

Crew Habits That Help

• Tape and label: “Do Not Unplug – Internet” on the router lead.
• Keep ladders and hoses clear of low‑voltage cabling.
• If you move networking gear, photograph original positions and put it back.

Handover Checklist (Two Minutes)

• Confirm router lights normal; run a quick speed/latency check.
• Ask the client to open a common app (video call or streaming) for 30 seconds.
• Document any lingering ISP issues and time of observation.

In general, contractors find that a simple before/after note or photo cuts disputes and unpaid “come back and fix” calls significantly.

Frequently Asked Questions

How long will a small UPS keep the internet up?

In general, a 600–1000 VA UPS commonly keeps a router and ONT/cable modem running 30–90 minutes, depending on power draw and battery health. If there’s also a network switch or multiple mesh nodes, runtime shortens. Prioritize router and ONT first.

What if I must kill the main breaker for several hours?

Give the client a clear window and suggest a hotspot plan. Move or power the router/ONT from a UPS in a cool, protected location and keep doors closed to reduce dust. For all‑day outages, a UPS won’t cover the entire period—set expectations early and verify service on restart.

Am I responsible for ISP outages discovered during my work?

You’re responsible for what you control. If lights on the ISP modem show loss of service to the street (not a power issue), note it in your job record and ask the client to contact their provider. Document before/after states to avoid blame for unrelated ISP faults.

Should I supply the UPS or ask the client to buy it?

For recurring interior work, many contractors keep a spare UPS for temporary use. For sensitive homes (remote workers, security systems), offering a pre‑priced UPS as an optional extra is practical. Make sure the client agrees to keep or return it and include that note in your proposal.

What about smart locks, alarms, and cameras?

Plan for them. Some devices rely on both power and internet. Schedule outages when they’re least disruptive, give the client a heads‑up to disarm if needed, and verify systems come back online at handover. Note any devices that require client passwords or app intervention.

Conclusion

You don’t need to be a network engineer to avoid internet blowups on small jobs. A five‑minute walkthrough, a short planned outage window, and a compact UPS will prevent most dropouts. Wrap it with a simple handover check and clear proposal language, and you’ll save time and keep reviews tidy.

Want to lock the message in while you’re still on site? Dictate the outage window and assumptions into Donizo, generate a professional PDF, send it with client portal access, and get a legally binding e‑signature. Once accepted, convert to an invoice in one click and track payment—no retyping. That’s less admin, fewer callbacks, and a smoother day for you and your client.
