You can often improve Wi-Fi coverage without relocating the router: clear space around it, reduce interference, and check signal and channel conditions. If a weak room remains, place an extender or mesh point where it still gets a strong connection—or use Ethernet to add a wired access point.
Improve the space around your router
Keep the router where its modem or cabling requires it, but raise it off the floor and place it in the open if possible. Avoid enclosing it in a cabinet, hiding it behind furniture, or putting it under a desk. Keep it away from large metal objects and likely sources of interference such as microwaves, cordless phones, and baby monitors. If the router has adjustable external antennas, try different orientations.

Walls and building materials matter: concrete, brick, and metal can weaken or block signals. Lower-frequency Wi-Fi bands generally cover farther than higher-frequency bands, while 6 GHz has shorter range and penetrates walls less effectively than lower bands. A faster band is not automatically the best choice for a distant room. Microsoft’s Wi-Fi guidance and Ofcom’s advice explain these trade-offs.

Test Wi-Fi in the rooms where you need it, not just beside the router. A Wi-Fi analyzer can help show signal strength and nearby network activity. Channel changes may help when networks are competing for airtime, but they will not fix a weak signal caused by distance or dense walls.

Many routers select channels automatically, and that can work well. If connection problems persist, try a less congested channel and compare performance in the same locations. Microsoft recommends considering channels 1, 6, or 11 on 2.4 GHz where available, and choosing a less occupied 5 GHz channel when needed. Google advises trying automatic channel selection first, then manual selection and speed tests if problems continue.
For a specific troubleshooting case—strong 2.4 GHz signal and a clear channel, but an unreliable connection—Microsoft suggests testing a 20 MHz channel width instead of Auto or 20/40 MHz. This is a diagnostic option, not a general setting that improves every network. See Microsoft Support and Google’s Wi-Fi interference guidance.

Choose an extension based on the weak area
| Situation | Option | Placement and trade-offs |
|---|---|---|
| One weak room, with usable Wi-Fi nearby | Wi-Fi range extender | Place it partway between the router and weak room, where it can still receive a good signal—not inside the dead zone. Extenders can affect speed and responsiveness, so test the result in the target room. |
| Several weak rooms, floors, or recurring dead zones | Compatible mesh system or add-on node | Nodes need a strong connection to one another. Put a node partway toward the weak area, keep it relatively close and unobstructed, and run the system’s mesh test. Confirm compatibility with your existing system. |
| Ethernet can reach the weak area | Wired Wi-Fi access point | Run Ethernet to the area and connect an access point, or use an extender configured in AP mode. A wired connection avoids relying on a weak wireless relay link. |
| Running Ethernet is impractical | Powerline adapter with Wi-Fi | Powerline carries network traffic over electrical wiring. Its performance depends on the home’s wiring and installation, so treat it as an option to test rather than a guaranteed fix. |
For one weak room: place an extender where it can still connect
An extender needs a usable signal from the router to repeat. Putting it in the dead zone gives it little or no signal to pass on. Start partway toward the weak room, then check both the extender’s connection to the router and the client device’s performance where you need coverage. TP-Link’s placement guidance also stresses avoiding locations where obstacles or distance undermine the link.
For several rooms or floors: position mesh nodes for backhaul
Mesh can suit wider or multi-floor coverage, but each node still needs a reliable connection to the rest of the system. Google’s guidance for Google Nest Wifi and Google Wifi says to place a point about halfway toward the weak coverage area and no more than two rooms away. Those are product-specific placement guidelines, not a universal range guarantee. Google also identifies an average signal below −77 dBm over the past 24 hours as a poor-average-signal insight for its Google Wifi/Nest Wifi points; that threshold is not a general industry cutoff. Use the mesh test in your system’s app and adjust placement if the backhaul is weak. Google Nest Help’s placement guidance explains its product-specific recommendations.

For a distant room: consider a wired access point
If a cable can reach the weak area, a wired access point is often a more direct way to provide Wi-Fi there than repeating a marginal wireless signal. An Ethernet run may be worth considering for a distant room or one separated by dense walls. If installing a cable is not practical, powerline networking is another possibility, but results depend on the electrical wiring.

- Record a baseline. Check signal and connection performance in the weak room and any other important locations before changing placement or settings.
- Make one change at a time. Start with router surroundings or channel selection, then recheck the same locations. This helps distinguish an improvement from a change that had no effect.
- Test an extender or mesh point at its intended location. Check the device’s connection back to the router or mesh, then test a client device in the room that needs coverage.
- Use the system’s diagnostic test. For mesh, run its connection or mesh test and move a node if the backhaul is weak. Try a different location and test again.
Home layouts and interference differ, so there is no dependable universal distance or percentage increase to promise from a placement change. Ofcom also notes that mesh equipment can cost more and larger homes may need multiple units; compare compatibility, number of weak areas, floors, backhaul type, supported bands, and likely speed trade-offs before choosing equipment.
