5 Settings to Speed Up Your Wi-Fi

Some homes get faster without a new plan. Placement and band first. Tonight’s order, before the expensive contract.

The 5 fixes, ordered by impact

5 Wi-Fi improvements: impact vs. difficulty (free first) ① – ③ are free and instant. ④ needs hardware. ⑤ is a monthly maintenance habit. Expected improvement Difficulty / cost ① Move the router Central location, 1 m+ off the floor, away from large metal objects 2–3× speed ★☆☆ Free · 5 min ② Switch to 5 GHz Connect to the "_5G" SSID in your Wi-Fi list 3–5× speed ★☆☆ Free · 1 min ③ Change the Wi-Fi channel (apartments) Avoid interference from neighbors — switch from auto to manual 2× speed ★★☆ Free · 10 min ④ Upgrade to a Wi-Fi 6/7 router Big improvement if coming from an old model 5–10× speed ★★★ $50–$150+ ⑤ Reboot once a month Unplug for 30 seconds and plug back in Stable speed ★☆☆ Free · 2 min
Fig 1: Start with ① and ②. Moving the router and switching to 5 GHz fixes most home Wi-Fi problems.

① Move the router

Just changing where the router sits can make a noticeable difference. Aim for a central location, slightly above floor level, with no large metal objects nearby (refrigerator, large TV). If it's currently behind the TV or on the floor, start here.

② Switch to 5 GHz

Does your Wi-Fi list show two networks like "HomeNet" and "HomeNet_5G"? The second one is 5 GHz and is generally faster. Use 5 GHz for phones and PCs nearby; stick with 2.4 GHz for smart home devices and rooms far from the router.

③ Change the Wi-Fi channel

In apartments, your Wi-Fi might be on the same channel as a neighbor's, causing interference. In your router's settings, switch "Channel: Auto" to a manually selected number, and use a free "Wi-Fi Analyzer" app to find the least crowded channel.

④ Upgrade to a newer router standard

If you're on an old router, a Wi-Fi 6 or 6E model can make a big difference. Prices vary by model; discuss with your family and choose one that matches your broadband speed and home size.

⑤ Reboot once a month

A router running for a long time gets sluggish. Unplugging it for 30 seconds once a month while everyone is asleep keeps it running smoothly.

Where signal is weak inside the home

What weakens Wi-Fi signals — and what to do about it The material of an obstacle makes a huge difference in how much signal is lost Signal loss Fix Reinforced concrete (RC) walls Apartment walls are especially tough on signal 90% loss Extender or mesh Wi-Fi Water-containing objects (bathroom, fish tank) Human bodies also absorb signal 70% loss Switch to 2.4 GHz Large appliances (fridge, washing machine, microwave) Microwaves interfere with 2.4 GHz while running 50% loss Use 5 GHz / move router Wooden walls / glass windows Standard home walls — signal passes through well 20% loss No action needed If nothing else works: a wired LAN connection is the strongest option. Worth it for a gaming room.

Practical tips

Placing a Wi-Fi extender near your desk can stabilize the signal in your room. But a poorly placed extender can actually make things slower. Put it roughly halfway between the router and your room, and measure speeds before and after. If the whole family is troubled by "the gaming room being slow," try moving the router and adjusting frequencies before buying anything.

Measure first, then change

With Wi-Fi improvements, don't rely on gut feeling. Before making any change, note the speed, ping, location, and time of day. Then try one thing at a time — move the router, switch to 5 GHz, change the channel — and measure again. Changing multiple things at once makes it impossible to know what helped. If online classes or gaming are the pain point, measure at different times of day (midday, evening, night) to see when congestion peaks.

Watch out for these common mix-ups

Things to keep in mind before changing settings
  • Changing the router's SSID (network name) means all home devices need to reconnect. Discuss it with your family first.
  • Most "Wi-Fi booster apps" do nothing useful, or are just ad-supported. Legitimate apps that actually change settings are rare.
  • Switching to 5 GHz is usually faster, but its signal is weaker through walls, so it may not reach distant rooms. Use both bands strategically.

How will this help you in the future?

The skill of tuning a home Wi-Fi setup will be useful when you have your own home, dorm, office, or shop. In SE and IT support roles, "Wi-Fi is slow" complaints are common, and working through placement, frequency, congestion, and device issues in order is exactly the skill that's needed.

Try it today

Today: move it once
  1. If it sits on the floor or behind a microwave, photograph it
  2. Move it higher and into the open, with a parent
  3. Watch one minute of the same video and count stalls

Summary

Wi-Fi speed depends on more than your broadband plan — placement and settings matter too. Try location, frequency, channel, hardware standard, and monthly reboots in that order. Starting with the free options lets you make an informed decision before spending any money. Opening the router's settings page once is the best first move.
