Is your Wi-Fi driving you crazy with slow speeds, dead zones, or constant buffering? You’re not alone. Weak Wi-Fi Signal is one of the most frustrating tech problems—but the good news? You can often fix it yourself!

In this step-by-step guide, we’ll cover 10 proven ways to boost your Wi-Fi signal, including:
✔ Free tweaks anyone can do in minutes
✔ Cheap upgrades under £50
✔ Advanced fixes for serious speed boosts
✔ How to test your Wi-Fi speed properly

By the end, you’ll have a faster, more reliable connection—no expensive engineer required!

📶 Why Is Your Wi-Fi So Slow? (Common Culprits)

Before fixing the problem, let’s diagnose it:

Issue Symptoms
Router in wrong spot Strong signal in one room, weak in another
Old router Slow speeds even near the hub
Interference Wi-Fi drops when microwaves/phones are active
Too many devices Speed tanks when family is online
ISP throttling Sudden slowdowns at peak times (7-11pm)

💡 Pro Tip: Run a speed test (Speedtest.net) near your router vs. a dead zone. If speeds differ drastically, your Wi-Fi (not broadband) is the issue.

🔧 10 Ways to Boost Your Wi-Fi Signal

1. Reposition Your Router (Free & Instant Fix)

✅ Do this first! Location affects signal more than anything.

Best spot:

  • Central in your home (Not tucked in a cupboard!)

  • Elevated (On a shelf, not the floor)

  • Away from interference (Microwaves, baby monitors, cordless phones)

❌ Worst spots:

  • Near thick walls/mirrors (Blocks signal)

  • Inside metal cabinets (Kills Wi-Fi)

2. Change Wi-Fi Channel (Reduces Interference)

If your neighbours’ Wi-Fi overlaps yours, switching channels can help.

How to:

  1. Download Wi-Fi Analyzer (Android) or NetSpot (Mac/PC).

  2. Find the least crowded channel (Usually 1, 6, or 11 for 2.4GHz).

  3. Log into your router settings (Check manual for login details).

  4. Change the channel under Wireless Settings.

(Advanced users: Use 5GHz band for less interference but shorter range.)

3. Upgrade Your Router (Best for Old Hardware)

If your router is 5+ years old, a new one could double your speed.

Best budget upgrades (£50-£100):

  • TP-Link Archer AX10 (Wi-Fi 6 for future-proofing)

  • ASUS RT-AX55 (Great range)

ISP-supplied routers (e.g., BT Hub, Sky Q) often underperform—consider replacing them.

4. Use a Wi-Fi Extender (Fixes Dead Zones)

Ideal for: Large homes, thick walls, or gardens.

Top picks:

  • TP-Link RE650 (£60, strong signal boost)

  • Netgear EX6120 (£45, easy setup)

Placement tip: Install halfway between router and dead zone.

5. Switch to Mesh Wi-Fi (Whole-Home Coverage)

Best for: Big houses (3+ bedrooms) with multiple dead zones.

Top systems:

  • Google Nest Wi-Fi (£200 for 3-pack)

  • TP-Link Deco M5 (£150 for 3-pack)

Why it’s better than extenders: Mesh systems seamlessly hand off your device between nodes.

6. Optimise Antenna Position (For External Antennas)

If your router has adjustable antennas:

  • Point one vertically (For upstairs/downstairs coverage).

  • Angle one horizontally (For wider range).

(No antennas? Skip this step.)

7. Limit Bandwidth-Hogging Devices

Some devices suck up Wi-Fi without you realising:

  • Smart TVs (Netflix in 4K = 25Mbps!)

  • Game consoles (Downloads in background)

  • Security cameras (Constant uploads)

Fix: Enable QoS (Quality of Service) in router settings to prioritise work/video calls.

8. Reduce Interference from Other Devices

Common Wi-Fi killers:

  • Microwaves (Yes, really!)

  • Bluetooth speakers

  • Baby monitors

Fix: Keep routers 3+ feet away from electronics.

9. Update Router Firmware (Security + Speed Fixes)

How to:

  1. Log into router settings (Usually 192.168.1.1 in browser).

  2. Check for firmware updates.

  3. Install & reboot.

(Do this every 6 months!)

10. Switch to Ethernet (For Critical Devices)

For gaming PCs, work laptops, or smart TVs, use Ethernet cables instead of Wi-Fi.

Bonus: Powerline adapters (£30) send internet through electrical wiring if cables aren’t practical.

🚀 Advanced Boosts (For Tech-Savvy Users)

  • Flash custom firmware (DD-WRT/OpenWRT) for more control.

  • Upgrade to Wi-Fi 6E (If your devices support it).

  • Use a VPN to bypass ISP throttling.

📉 When to Call Your ISP

If all else fails, your broadband line might be the issue. Contact your provider if:

  • Wired speeds are slow too (Test via Ethernet).

  • Outages are frequent.

  • Router keeps resetting.
