Can a shiny new kitchen really turn your living room into a WiFi dead zone? It sounds wild, but plenty of folks run into this exact issue—strong connection everywhere except the one place you want to relax and stream your favorite shows. If a recent kitchen renovation left you with just one bar (or less) in the living room, you’re not alone. Let’s dig into why a simple upgrade can mess with your signal—and how to fix it.

How Renovations Can Affect Your WiFi Signal

Most of us don’t think about our wireless router once it’s set up. But home renovations—even if they don’t touch the wiring—can definitely mess with WiFi signals. Here’s how:

• New walls or surfaces: Materials like tile, stone, or even thick wood can block radio waves.
• Metal objects: Appliances or metal-backed cabinets reflect and scatter signals.
• Hidden electrical work: Even if nobody touched the outlets on that shared wall, new wiring or under-cabinet lighting could introduce interference.
• Layout changes: Moving big stuff (like a fridge) shifts how signals bounce around.
• Router location: Sometimes a small change in furniture or wall makeup affects signal paths more than you’d expect.

Even standard subway tile isn’t usually an issue—but grout with metallic additives or moisture-resistant barriers behind backsplashes can create surprising blocks. You can read more about building materials and signal loss over at CNET, which breaks down which materials cause the most trouble for WiFi.

The Mystery of Sudden Dead Spots

What really throws people is when everything works everywhere else—just not in that one room. In your case, both the router and its position haven’t changed since before the kitchen reno. That means something about the new build is interrupting the path between your router upstairs and your living room TV.

Let’s put on our detective hats for a second. The most likely culprits:

• Cupboards & Cabinets: Are they solid wood or have any metal mesh inside? Some imported or custom cabinetry uses hidden wire for reinforcement.
• Bigger Appliances: Was a refrigerator moved closer to that shared wall?
• Tiling & Barrier Materials: Waterproofing membranes can contain foil layers that block radio waves.
• Cable Routing: Sometimes contractors tuck new wires directly in walls without you knowing.

A surprising number of people find their “dead spot” is caused by something as simple as a new microwave sitting close to where their router’s signal passes through.

Simple Ways to Diagnose and Fix Your WiFi Issues

Before shelling out cash for mesh systems or calling in experts, try these steps:

• Walk Test: Use your phone to check where signal drops off as you move between rooms. This helps pinpoint exactly where things go south.
• Change Router Channel: Interference from neighbors’ networks can make things worse. Most routers let you swap channels in settings (see this guide from PCMag).
• Reboot Everything: Sounds basic, but sometimes routers just need a fresh start after weeks of construction dust and power cycles.
• Add an Extender: Plugging in a small WiFi extender (even temporarily) near the living room may bridge the gap until you find a permanent solution (Wirecutter has top picks here).
• Tinker With Placement: Try moving your router just a foot or two—sometimes that’s all it takes to redirect the strongest part of its “beam.”

If all else fails and you’ve got some budget set aside (always nice!), consider upgrading to a mesh network system—they’re designed for homes with tricky layouts and thick walls.

A Real-Life Anecdote: When “Invisible” Changes Matter Most

One homeowner thought their new stone backsplash was ruining their streaming nights—but it turned out their contractor had run speaker wire directly through the shared wall behind their TV during installation. The wire itself didn’t carry power but acted like a tiny antenna for interference! Moving the TV stand six inches away from the wall cleared up buffering instantly.

It sounds odd, but even unseen changes—like insulation upgrades or “hidden” cabling—can have big effects on wireless signals.

Breathe Easy—Your Streaming Nights Aren’t Over

It may feel like this problem came out of nowhere after your kitchen reno—but with some detective work and maybe minor tech tweaks, you’ll likely get back to seamless streaming soon. Sometimes fixing home WiFi issues is part science…part trial-and-error.
