To improve home Wi-Fi, first check whether the trouble is weak coverage, wireless congestion, a device limitation, or the broadband connection itself. Start by moving the router to a central, open spot and testing a wired connection if possible. An extender or mesh system can help when the layout is the problem, but neither is a guaranteed fix.
The headline’s claim that 20 methods were tested and six made the biggest difference cannot be substantiated by the available evidence, so this guide presents practical troubleshooting steps rather than claiming personal test results.
First find out what is actually slow
“Slow internet” can describe several different problems. A weak signal in one room points toward coverage; trouble across multiple rooms may involve congestion, the router, or the incoming broadband service. One device struggling while others work normally may indicate that device’s Wi-Fi support or settings.
Recommended Free Tools
- Compare locations. Check whether performance worsens only in one room or on one floor. A localized problem is more consistent with a coverage obstacle or distance than a whole-home service issue.
- Compare devices. If possible, try another phone or computer in the same spot. If only one device has trouble, investigate that device’s Wi-Fi connection and compatibility before buying network equipment.
- Test Ethernet if available. Connect a computer directly to the router with an Ethernet cable and compare its performance with Wi-Fi. The Federal Communications Commission says a direct Ethernet connection provides the highest speeds and alleviates Wi-Fi congestion (FCC consumer guidance). If Ethernet is also poor, the issue may be with the router, the service reaching your home, or another part of the connection; the comparison alone does not prove the internet provider is at fault.
Try these six changes before buying hardware
1. Move the router to a central, open location
The FCC advises placing the router centrally to maximize coverage. Put it in an open area rather than a cabinet or behind furniture, and avoid major obstructions where practical. Walls, floors, masonry, metal, plumbing, appliances, and water can weaken or obstruct Wi-Fi signals. A move that improves one room may change coverage elsewhere, so check the places where you use the network most.

2. Test the available Wi-Fi bands
Wi-Fi bands trade range against speed and compatibility. The FCC says 2.4 GHz generally reaches farther, while 5 GHz is faster but has shorter range and may be less crowded (FCC consumer guidance). Consumer Reports notes that 6 GHz is available with compatible Wi-Fi 6E devices (Consumer Reports’ Wi-Fi signal guidance).
Try the band that works best for the device and location rather than assuming the newest or fastest band is always preferable. Device support, distance, walls, and local interference all affect the result. If your router combines bands under one network name, its management app or settings may control band selection; the exact steps vary by router.

3. Check for household congestion
Several demanding activities at once—such as video, gaming, VPN use, and video conferencing—can bog down a home network. The FCC suggests considering schedules and managing connected devices. If slowdowns occur at particular times, pause or reschedule a large download or other nonessential network use and see whether the experience improves.

4. Update or replace a router only when there is a reason
A router may be worth replacing if it does not support your devices, lacks needed coverage, or cannot keep up with the number of connected devices. Before shopping, check whether the manufacturer still provides firmware and security support, and confirm that the router’s Wi-Fi and Ethernet capabilities suit the devices you intend to connect. A faster router cannot fix an undersized broadband plan, a service outage, or every source of interference.

5. Use an extender for a single weak area
A Wi-Fi extender is a targeted option for one dead zone, not a cure-all for a slow network. Consumer Reports recommends placing one roughly midway between the router and the weak area, where it can still receive a useful signal (Consumer Reports’ extender guidance). If it is placed where the router signal is already very poor, it has little useful connection to repeat.
Performance depends on incoming service speed, distance, obstacles, coverage needs, and how many people are using the network. Repeating over the same band can reduce throughput, so an extender may improve reach without delivering the same performance as a strong connection near the router.

6. Consider mesh for broader or more complex coverage needs
A mesh system uses multiple units that work together to spread Wi-Fi coverage. It may suit a larger, multistory, or complex home where several areas have dead zones. A single router may be enough for a smaller or simpler layout. Building materials, node placement, distance between units, and household demand still matter; buying mesh is not a guaranteed improvement (Consumer Reports’ Wi-Fi signal guidance).
Choose between an extender, mesh system, and router replacement
Match the equipment to the pattern of the problem, not just the advertised speed. Consider the home’s size and number of floors, whether one spot or several rooms need coverage, the distance and obstacles between the router and weak areas, wired Ethernet options, device compatibility, setup needs, and cost. No one equipment type is best for every home.

| Option | Most relevant when | Key limitation to consider |
|---|---|---|
| Wi-Fi extender | One localized dead zone needs a targeted signal boost. | It must receive a useful signal from the router; distance, obstacles, and repeating over the same band can constrain performance. |
| Mesh system | Several rooms, multiple floors, or a complex layout need broader coverage. | Results depend on placement, node spacing, obstacles, device compatibility, and demand. |
| Replacement router | The existing router is outdated for your devices or needs, lacks support, or cannot provide suitable coverage. | It does not fix a broadband plan or service problem, and may not overcome physical interference. |
When the problem appears to be the broadband connection
If a wired device connected to the router is also slow, check for a service outage and compare the result with the speeds and terms of your broadband plan. A wired test removes the Wi-Fi link from that particular comparison, but the result can still reflect the router, the service connection, or other factors. FCC broadband measurement material and Consumer Reports’ guidance discuss assessing service separately from home Wi-Fi (Consumer Reports’ broadband guidance; FCC broadband measurement information).
