Your internet plan is fast, but your Wi-Fi is slow - here's how to fix the bottleneck between your router and devices.

💡What's Happening

You're paying for 300 Mbps (or more), but when you run a speed test on Wi-Fi, you're getting 30 Mbps or less. Meanwhile, devices connected with an Ethernet cable get the full speed. This is incredibly frustrating because you're not getting what you're paying for. The good news? The problem is almost always your router or Wi-Fi settings, not your internet plan itself.

✓Quick Checks (Do These First)

  • Run a speed test while standing next to your router. If speed is good there but bad elsewhere, it's a coverage problem.
  • Check which Wi-Fi band you're using. Are you on 2.4 GHz or 5 GHz? Your phone settings will show this.
  • Count how many devices are connected. Open your router admin page to see the device list.
  • Look at your router's age. If it's more than 4-5 years old, it might not support your current speeds.
  • Restart your router. Unplug for 30 seconds, plug back in, wait 2 minutes, test again.

🔧Step-by-Step Fixes

Fix 1: Switch to the 5 GHz Band

The 5 GHz band is much faster than 2.4 GHz but has shorter range. Most modern routers broadcast both bands.

  1. On your device, go to Wi-Fi settings
  2. Look for your network name with "-5G" or "5GHz" at the end
  3. Connect to that network instead of the regular one
  4. Run a speed test - you should see a significant improvement

If you don't see a separate 5 GHz network, you may need to enable it in your router settings (see Fix 3).

Fix 2: Position Your Router Properly

Router placement has a huge impact on Wi-Fi speed. Many people hide their router in a closet or behind furniture, which kills the signal.

  1. Move your router to a central location in your home
  2. Place it on a shelf or desk, not on the floor
  3. Keep it away from thick walls, metal objects, and appliances
  4. If it has external antennas, position one vertically and one horizontally
  5. Run speed tests from different rooms to verify improvement

Fix 3: Change Your Wi-Fi Channel

Your router shares airspace with neighbors' routers. If everyone is on the same channel, speeds suffer.

  1. Download a Wi-Fi analyzer app (like WiFi Analyzer for Android or WiFi Explorer Lite for Mac)
  2. Run the app to see which channels are crowded
  3. Access your router admin page (usually 192.168.1.1 or 192.168.0.1 in a browser)
  4. Log in (check the sticker on your router for credentials)
  5. Find Wireless Settings > Channel
  6. For 2.4 GHz, choose channel 1, 6, or 11 (whichever is least crowded)
  7. For 5 GHz, try channel 36, 40, 44, or 48
  8. Save settings and test your speed

Fix 4: Update Your Router's Firmware

Outdated firmware can cause performance issues and security vulnerabilities.

  1. Access your router admin page
  2. Look for Administration, Advanced, or Firmware Update
  3. Click Check for Updates
  4. If an update is available, click Update and wait (don't turn off the router during this process)
  5. Router will restart automatically
  6. Test your speeds after the update completes

Fix 5: Enable QoS (Quality of Service)

QoS helps prioritize important traffic so streaming or video calls don't get choked by downloads.

  1. Access your router admin page
  2. Find QoS or Quality of Service settings
  3. Enable QoS and select your internet speed
  4. Set priorities (Gaming/Streaming = High, Downloads = Low)
  5. Save and test performance during heavy use

⚠️If Nothing Worked

If you've tried all these fixes and Wi-Fi is still slow, your router may be outdated or incapable of handling your internet speeds. Look up your router model's specifications - if it only supports Wi-Fi 4 (802.11n) or older, it can't deliver speeds above 150-300 Mbps. Consider upgrading to a Wi-Fi 5 (802.11ac) or Wi-Fi 6 (802.11ax) router that matches your internet plan's speed.

📞When to Call a Pro

If you're not comfortable logging into your router settings, or if you've tried everything and still have slow speeds, it's time to get expert help. There might be interference issues, configuration problems, or you may need professional guidance on choosing the right router upgrade.
