You know that frustrating moment when you’re video calling from your bedroom, and suddenly the picture freezes, or when your smart home device keeps disconnecting? Welcome to Wi-Fi dead zones.
Thankfully, you don’t need a new router or repeater setup to fix them. I’ve used Wi-Fi analyzers to boost my Wi-Fi connection before, and fixing poor Wi-Fi is a simple matter of mapping Wi-Fi dead zones and fixing them accordingly.
Wi-Fi dead zones aren’t random; they’re predictable
Walls, furniture, and physics are usually to blame
Wi-Fi dead zones aren’t some mysterious curse; they’re physics. Radio signals weaken as they travel, get absorbed by walls and furniture, bounce around, and interfere with other signals. The frustrating part? You probably can’t see any of it happening.
Start by downloading a Wi-Fi analysis app on your phone. I use Wi-Fi Analyzer for Android, but any app that can show your Wi-Fi network’s signal strength will suffice. These apps let you see your signal strength in real time as you walk around, which is helpful for figuring out which parts of your house have the weakest signals.
I ended up creating a rough floor plan of my apartment, walking around systematically, and letting the app plot out where my signal was strong versus weak. This takes barely 15 minutes of your time but gives you a pretty good understanding of Wi-Fi signals around your house.
What this heatmap revealed was predictable but useful. My router was near the front door, which meant the further corners of my house got almost no signals. The kitchen, with all its metal appliances and cabinets, was practically a signal graveyard. These zones weren’t necessarily unreachable. They were just unoptimized.
Router placement matters more than router specs
One bad corner can sabotage your entire network
The simplest way of fixing Wi-Fi dead zones in your house is to find the optimal router location in your home. The best spot for a Wi-Fi router is always in the center of the area you want it to cover. Wi-Fi signals travel equally in all directions from your router’s antennae, meaning if you place the router in the middle of your house, you should get the best coverage possible everywhere.
In reality, walls, electrical appliances, furniture, and other obstacles will prevent Wi-Fi signals from traveling equally in each direction. Regardless, starting in the middle lets you work your way around a central space in your house to ensure you set your router in a place with the least disturbance and the best signal strength in all four corners of your house.
Your router’s antenna position also matters. I have two external antennas on my router. The standard advice is to position them perpendicular to each other—one vertical, one horizontal. This creates balanced coverage across an entire floor.
However, since you already have a heatmap of your Wi-Fi dead zones, experiment with router placement and antenna positions to figure out the optimal router position for your apartment. Just make sure you avoid router placement myths that do more harm than good.
Your Wi-Fi channel might be fighting your neighbors
Congestion is real, and auto-select often gets it wrong
This might sound technical, but it is actually quite simple: Wi-Fi channels. Think of channels like radio frequencies—if everyone in your apartment building is using the same channel, everyone’s signal gets weak. On the 2.4 GHz band, there are only three truly non-overlapping channels: 1, 6, and 11. Most routers default to channel 6, which means interference in densely populated areas.
I used the same Wi-Fi analyzer app to check which channels were least crowded in my building. Depending on your situation, use the least congested channel in order to get better speeds and signal stability. The exact settings you need to change will vary based on your router’s specific make or model, but a quick peek at the manual should clear up any doubts.
Network Congestion Is Slowing Down Your Wi-Fi, but There Are 2 Easy Fixes
These two small changes can make a surprising amount of difference to your Wi-Fi speeds.
If your router has 5 GHz capability, and in 2026 it really should, you’re already much better off. There are dozens of non-overlapping channels, so interference is less of an issue. That said, 5 GHz signals don’t travel as far, so you’re going to have to be closer to the router.
Channel width also plays a role. I use 20 MHz for 2.4 GHz, as narrower channels lead to less interference, and 40 MHz for 5 GHz, as wider channels allow for faster speeds if congestion allows.
Sometimes you just need a little backup
Extenders, mesh nodes, and old routers can fill the gaps
In case you didn’t know, most routers have a repeater capability built in to enhance your Wi-Fi network’s range. This means that in addition to receiving your internet over the WAN port from your ISP and transmitting it via Wi-Fi, they can also just receive Wi-Fi signals from another router and “repeat” those signals forward, effectively enhancing your Wi-Fi range.
You can easily fix a Wi-Fi dead spot with an old router, although it will require some basic setup. Do keep in mind that, depending on how old your router is, it might not be the most secure network device to use, but you’ll be just fine using it on a home network. Regardless, this is a no-cost, duct-tape way of solving Wi-Fi range issues and works best in certain situations.
You can also consider using Powerline adapters to run a wired connection between your router and PC using the existing electrical wiring in your house. It could be a great fix for your smart TV’s awful internet.
However, be mindful of the myths around Powerline adapters. They might sound like a plug-and-play solution, but there are factors such as your house wiring and speed drop-offs that can impact the actual speeds you get.
Fixing Wi-Fi dead zones doesn’t have to cost a fortune
Smart tweaks beat throwing money at new hardware
These fixes aren’t a guarantee that your Wi-Fi dead zones will vanish. After all, there’s only so much range you can get out of a single Wi-Fi router. However, they will improve your internet experience without asking a dime in return.

Random Wi-Fi outages absolutely suck—so take some steps to resolve the problem.
Dead zones usually aren’t inevitable; they’re just the result of a suboptimal setup. Most people already have the tools they need to fix them—they just don’t realize it.
