01 Step 1: Diagnose the Problem
Before buying anything, understand where your WiFi signal is weak and why. Walk around your home or office with your phone and watch the WiFi bars. Note exactly where the signal drops.
Free WiFi analyzer apps
Download a free WiFi analyzer app for your phone — WiFi Analyzer (Android) or AirPort Utility (iOS). These show exact signal strength in dBm and help identify the best locations for your router and extenders.
02 Step 2: Free Router Placement Tips
Before spending money, try these free fixes. Poor router placement is the #1 cause of weak WiFi — fixing this alone solves most coverage issues.
Place router centrally, elevated (on a shelf), away from walls and metal objects. Keep antennas vertical. Position router in open space, not inside a cabinet or cupboard. Raise it higher than furniture level.
Don't hide routers in corners, behind TVs, inside closets, on the floor, or near microwaves and cordless phones. Avoid placing near large metal appliances or fish tanks (water absorbs WiFi signals).
Try before you buy
Move your router to a more central, elevated location first. Many dead zones disappear with just this free change.
03 Step 3: Choose Your Solution
If placement didn't fix everything, here are your four main options — ranked from most effective to most budget-friendly. Prices are estimates in Ghana Cedis (GHS).
Multiple nodes that work together as a single seamless network. Perfect for large homes or multi-floor offices.
- Single network name — seamless roaming
- Excellent coverage (2,000–6,000+ sq ft)
- Easy app setup
- Most expensive (₵2,250–7,500+)
- Overkill for small apartments
A plug-in device that rebroadcasts your existing WiFi signal to dead zones. Works well for small to medium areas.
- Affordable (₵450–1,500)
- Easy to set up
- Works with any existing router
- Cuts bandwidth in half
- Separate network name (usually)
- Signal still needs to reach it
Uses your home's electrical wiring to carry internet signal to another room. No WiFi signal lost to walls.
- No WiFi signal loss through walls
- Works where WiFi doesn't reach
- Stable connection
- Requires electrical outlets on same circuit
- Speed varies with wiring quality
- Doesn't work across different electrical phases
Already covered above — try this before buying anything. A better positioned router often fixes everything.
- Completely free
- Takes 5 minutes
- May not be enough for large spaces

05 Common Interference Sources
WiFi signals can be disrupted by everyday household and office items. If your signal is weak in a specific spot despite good coverage elsewhere, check for these nearby.
- Microwaves — Operating microwave ovens emit radiation that interferes with 2.4GHz WiFi. Keep routers away from kitchens.
- Cordless phones — Older cordless phones use the same 2.4GHz frequency band. Upgrade to DECT 6.0 phones or move the router away.
- Bluetooth devices — Speakers, headphones, and mice all use 2.4GHz. Multiple active Bluetooth devices can cause congestion.
- Neighbour WiFi networks — Overlapping channels from nearby networks cause interference. Use the 5GHz band or switch to a less crowded channel.
- Water (fish tanks, pipes) — Water absorbs WiFi signals. Large fish tanks, water heaters, or plumbing runs inside walls can block signal.
- Concrete walls & metal — Reinforced concrete and metal studs block WiFi much more than drywall. Mirrors (with metallic backing) also block signal.
06 2.4GHz vs 5GHz vs 6GHz
Modern routers broadcast on multiple frequency bands. Understanding the difference helps you choose the right one for each situation.
| Band | Range | Speed | Best For | Rating |
|---|---|---|---|---|
| 2.4GHz | Long range (better through walls) | Slower (~100-300 Mbps) | Devices far from router, smart home devices, cameras | Good for range |
| 5GHz | Shorter range | Faster (~500-1200+ Mbps) | Streaming, gaming, video calls, nearby devices | Best for speed |
| 6GHz (WiFi 6E) | Shortest range | Very fast (~1-2+ Gbps) | High-bandwidth, low-latency — if your devices support it | Best for congestion |
Use the same SSID for both bands
Most modern routers offer "band steering" — they automatically direct devices to the best band based on signal strength. Use the same network name for 2.4GHz and 5GHz bands, and let your devices decide.
07 Common Mistakes to Avoid
- Putting the extender in the dead zone — The extender needs good signal from your router to repeat. Place it halfway, not in the dead spot.
- Using power strips for powerline adapters — Powerline adapters must be plugged directly into wall outlets. Power strips block the signal completely.
- Hiding the router in a cabinet or behind the TV — Walls and cabinets absorb WiFi signal. Place routers in open space at head height or above.
- Buying a new router when you don't need one — Most dead zones are solved by moving the existing router or adding an extender. Don't replace your router unless it's very old.
- Using only 5GHz for distant rooms — 5GHz doesn't travel through walls well. For far rooms, use 2.4GHz or a mesh node in that area.
Dead Zones Eliminated
Start with the free router placement tips — they solve most coverage problems. If you still have dead zones, choose the solution that fits your space and budget. A mesh system is ideal for large homes; an extender is great for a single problem room.
