Short answer: Measure performance first, then move your existing router toward the center of the home, raise it into an open position, reduce walls and metal between the router and your device, and test the 2.4 GHz, 5 GHz, or 6 GHz option that suits each location. If speeds are still poor beside the router, investigate the internet connection rather than changing Wi‑Fi placement again.
Start with a baseline so you know what actually improved
A speed test is useful evidence, but it is not a pure measurement of radio signal. The result also reflects your internet plan, modem or router connection, device capability, network traffic, distance, walls and other building materials. Microsoft recommends testing in several locations and recording the results before making changes, then repeating the same tests afterward. See its Wi‑Fi and your home layout guidance.

- Choose the room where Wi‑Fi is unreliable and one location close to the router.
- Run the same speed test in both places. Record download speed, upload speed, latency if shown, the device used, and the band or network name connected at the time.
- Repeat the test once if the result looks unusual. Keep the device in the same place and use the same test method.
- If possible, test a second phone or computer. If only one device performs badly, its adapter, software or compatibility may be the limiting factor rather than the whole wireless network.
- After every change, retest both locations. A change that helps one room but harms the area near the router is a trade-off, not an overall improvement.
Use the baseline to classify the problem. A large difference between the near-router and distant results points toward the local wireless path or the home layout. Poor results everywhere, including next to the router and on more than one device, make the provider connection, modem-router link or device limits worth checking. That distinction prevents endless placement changes when the underlying service is slow.
Move the router before changing technical settings
The most effective free adjustment is often physical. Microsoft’s setup guidance recommends a central location, placing the router off the floor, and keeping it away from walls and metal objects. Read the details in Setting up a wireless network in Windows.

A position that usually deserves testing
- Near the center of the home: This reduces the average distance to rooms on different sides of the building. If one area is the priority, shift the router toward that area while keeping as much central coverage as possible.
- Raised and uncovered: A shelf or open table is preferable to the floor, a closed cabinet or the space under a desk. Leave air around the router rather than surrounding it with books or other equipment.
- With a clear path: Fewer intervening walls and large objects generally give the signal fewer obstacles to cross. Do not assume that moving the router a small distance always helps; test the exact locations.
- Away from metal: Metal furniture, appliances and other large metal objects can obstruct or reflect wireless energy. Move the router away from them where the cable allows.
Compare positions systematically
| Router position | What to check | How to judge it |
|---|---|---|
| Original location | Distance and number of walls to the problem room | Use this as the control result |
| More central location | Whether multiple rooms gain a shorter or clearer path | Retest the problem room and the near-router location |
| Raised, open location | Less furniture, floor-level obstruction and enclosure | Keep it only if repeat tests improve the target area without unacceptable losses elsewhere |
| Closer to the target room | Shorter distance but possibly worse coverage on the opposite side | Use when one area matters more and the whole-home results remain acceptable |
There is no universally best spot. Home shape, wall construction, router antenna design and the client device all change the result. Make one physical change at a time and keep the better position only after repeat measurements.
Choose the band that fits the room and device
Many routers advertise 2.4 GHz and 5 GHz networks; newer compatible equipment may also offer 6 GHz. Some routers show separate network names, while others use one name and automatically steer compatible devices between bands. Google describes this behavior, including band steering on its Wi‑Fi systems, in How 2.4, 5 GHz and 6 GHz bands work. Menus and behavior differ by router, and some smart-home products support only 2.4 GHz.
| Band | Range through obstacles | Throughput potential | Interference and channel considerations | Compatibility |
|---|---|---|---|---|
| 2.4 GHz | Generally reaches farther and passes obstacles better | Usually lower potential than 5 GHz | Nearby networks and household electronics can crowd or disturb it | Broadest support; some devices support only this band |
| 5 GHz | Shorter range and more affected by walls | Can provide faster throughput when the device is close enough | Assess nearby access points and the number of walls between router and client | Requires a compatible router and client |
| 6 GHz | Shorter range; generally best nearer the router | Results depend on the compatible equipment and local conditions | Use only where the newer equipment and location make it practical | Requires newer compatible router and client hardware |
Try 2.4 GHz for distant or obstructed rooms
When a device is far away or separated by several walls, connect it to the 2.4 GHz network if the router exposes that choice. Its longer reach may produce a steadier connection even when a nearby 5 GHz network looks faster in the same room. This is a test, not a rule: measure the actual result with that device in that room.

Try 5 GHz near the router
For a nearby computer, television or phone that needs higher throughput, test 5 GHz. Its shorter range means the result can deteriorate quickly as walls and distance increase. If the router combines both bands under one name, you may not be able to force a choice; move the device closer, temporarily use separate names if the router supports that setting, or follow the router’s band-selection controls.
Use 6 GHz only when both ends support it
A 6 GHz network cannot help a device that lacks a compatible radio. Because its useful range is shorter, it is normally a near-router option rather than a solution for a distant room. Keep the 2.4 GHz or 5 GHz option available for older or farther-away devices.
Reduce radio interference around the router and client
Wireless problems can come from more than neighboring Wi‑Fi. Apple documents interference from electronics and practical isolation steps in Resolve Wi‑Fi and Bluetooth issues caused by wireless interference; Google also lists interference and placement among the factors affecting performance.

Sources worth checking
- Microwave ovens, especially when the router or client is very close to one.
- Bluetooth equipment, cordless phones and wireless cameras.
- Dense clusters of electronics, power cables and large appliances.
- Other Wi‑Fi access points in nearby homes or offices.
The effect depends on the equipment and its placement, so do not assume that every listed device is causing your problem. Move the router or the affected client away from the suspected source when practical. For a controlled check, switch nearby electronics off one at a time, repeat the same test, and turn each item back on before checking the next. If performance changes only while one device is off, keep the router and client farther from it or avoid using them together.

Check channels instead of guessing
Nearby Wi‑Fi networks can compete for the same radio space. Leave automatic channel selection enabled if it is working well; it is a sensible starting point. If the connection remains unreliable and your router permits manual selection, inspect the surrounding networks first rather than picking a channel blindly.
2.4 GHz channel choices
Microsoft advises comparing channels 1, 6 and 11 on 2.4 GHz, using the one that has the least congestion and suitable signal conditions in your location. Router labels vary, but the setting is normally under wireless or radio configuration. Change one value, save it, allow the router to restart its wireless service if required, and repeat the baseline test.

5 GHz channel choices
On 5 GHz, consider how many access points are visible around you and test the available options your router presents. The best choice depends on the surrounding networks, walls and client device; there is no channel that wins in every home.
When 20 MHz width is worth trying
Microsoft notes that 2.4 GHz channel width can cause reliability problems with some older adapters. If the signal appears strong and the channel is reasonably clear but the connection still drops or behaves erratically, try a 20 MHz channel-width setting. Treat this as a later troubleshooting step because it can reduce potential throughput. Retest reliability and speed after changing it, and restore the previous setting if it does not help.

| Test pattern | More likely interpretation | Next action |
|---|---|---|
| Fast near the router, much slower in one room | The local wireless path, distance, obstacles or interference is contributing | Work through placement, band and interference tests |
| Slow near the router and in the distant room on one device | That device’s capability or condition may be limiting the result | Repeat with another compatible device and compare bands |
| Slow near the router on several devices | The provider connection, modem-router link or wider network may be at fault | Check service status and provider performance before making more Wi‑Fi placement changes |
| Only one band is slow in one location | Range, walls, congestion or compatibility may favor the other band | Use the better-performing band for that device and location |
This is a diagnostic distinction, not proof of a single cause. Repeat tests at different times if household traffic varies, and keep the device, location and test method consistent.
A no-cost troubleshooting sequence
Use this order so each step is reversible and its effect is measurable.
- Record the baseline: Test near the router, in the problem room and, if possible, on a second device.
- Relocate the router: Try a central, raised, open position away from walls, metal and large obstructions. Retest both locations.
- Test the bands: Use 2.4 GHz for the far or obstructed location and 5 GHz near the router when compatible; test 6 GHz only with compatible newer equipment and a short path.
- Isolate interference: Move the router or client from microwaves, Bluetooth devices, cordless phones, cameras, dense electronics and power cables. Turn suspected electronics off one at a time to verify an effect.
- Review channels: Keep automatic selection if it performs well. Otherwise compare 2.4 GHz channels 1, 6 and 11 based on observed congestion, then assess the available 5 GHz channels and nearby access points.
- Try 20 MHz on 2.4 GHz only if needed: Use it when reliability is poor despite a strong signal and a clear channel, especially with an older adapter. Retest and revert if performance worsens.
- Classify the remaining problem: If the near-router result is still poor across devices, investigate the internet service or modem-router connection rather than repeating the same wireless adjustments.
Common mistakes that waste time
- Judging by the Wi‑Fi icon alone: Bars do not tell you whether the provider connection is fast. Use repeatable tests in fixed locations.
- Changing several settings at once: You will not know which change helped or harmed performance. Make one adjustment, then measure.
- Forcing every device onto one band: Older or smart-home devices may support only 2.4 GHz, while a distant device may perform better there than on 5 GHz. Let combined-band systems steer compatible clients or choose separately where the router allows it.
- Putting the router out of sight: A cabinet, floor corner, desk underside or position beside metal can add obstacles that a central open shelf avoids.
- Choosing a channel by reputation: Congestion varies by building and time. Compare what your router actually observes, and use the available controls rather than assuming one universal winner.
- Continuing Wi‑Fi tweaks when every nearby test is slow: That pattern points toward service, modem-router connectivity or device limits. Record the evidence before contacting the provider.
Final checklist
Before declaring the problem solved, verify that you have a before-and-after result for the room that mattered, the router is central, raised and open where practical, the chosen band matches the device and distance, obvious interference sources have been isolated, and channel changes were based on observed conditions. If the connection remains poor beside the router on multiple devices, treat it as a separate internet-service investigation. These steps use the equipment already in your home and avoid buying an extender, replacement router or analyzer before you know what the actual bottleneck is.
