To improve Wi-Fi at home, first check what connection your device is using and where the signal weakens. Then test different locations and bands before buying equipment. Your router and device negotiate a Wi-Fi mode they both support; you usually do not select that mode directly.
Step 1: Check the connection and find where it struggles
Test Wi-Fi where you normally use the affected device, then compare it with a test near the router. If performance improves nearby, distance, obstructions, or interference may be involved. Wi-Fi uses radio signals, so walls, other obstacles, and competing radio activity can affect the connection.
On Windows, open Command Prompt and run:
netsh wlan show interfacesLook for the connected interface’s radio type in the output. The mode in use is negotiated between the access point and the device, based on what both support and the radio conditions. A router that supports 802.11 a/b/g/n does not mean every connected device uses every mode.
Ask Leo!’s guide describes this negotiation and the command in more detail: 5 Steps to Better Wi-Fi In Your House.

Step 2: Test a better position for the router or device
Try moving the router toward the area where you need coverage, or move the device to see whether a small change helps. A central location is a useful starting point, not a guarantee: walls and the layout of the home matter, and the geometric center may not be the best practical location.
Keep the router away from nearby electronics and large metal objects where possible. Change one thing at a time, then retest from the same spot so you can tell whether the move helped.

- With advanced Deco Mesh Technology, units work together to form a unified network with a single network name. Devices automatically switch between Decos as you move through your home for the fastest possible speeds.
Step 3: Compare available Wi-Fi bands and channels
If your router presents separate 2.4 GHz and 5 GHz networks, try each from the problem location. In general, 5 GHz can be faster but is more sensitive to distance and obstructions. The better choice depends on the room, obstacles, and the device’s connection.

If you change a channel, use a setting supported by both your router and wireless adapter; the available controls vary by equipment. Retest after a change rather than assuming a particular channel will work best in every home.

Step 4: Extend coverage if testing shows a dead zone
If repositioning and band tests are not enough, choose an extension method based on whether Ethernet can reach the weak area. A wired access point is generally the preferred option when a cable route is practical: it connects back to the router over Ethernet and provides Wi-Fi from its new location. A wireless repeater avoids running a cable, but its connection still depends on the wireless signal. Mesh is another multi-node approach for extending coverage around a home.
| Option | Connection to the router | Useful when | Trade-off |
|---|---|---|---|
| Wired access point | Ethernet | You can run a cable to a useful location | Requires a cable route and compatible setup |
| Wireless repeater or range extender | Wireless | Running Ethernet is impractical | Relies on the wireless link between the router and repeater |
| Mesh system | Multiple nodes; connection details vary by system | You want a multi-node approach to whole-home coverage | Coverage and performance depend on placement and system specifications |
There is no universal house-size threshold or guaranteed coverage radius for these options. Placement and the building layout matter. Check the equipment’s current specifications and compatibility before choosing a system; mesh designs do not all use the same backhaul arrangement.

Step 5: Upgrade the client—or use a cable
If only one computer has poor Wi-Fi, the issue may be specific to its adapter or antenna rather than the home’s overall coverage. A compatible USB Wi-Fi adapter may be an option, but confirm that it suits the device and its connection needs. Replacement antennas are only appropriate for access points designed to use them, and must be compatible with that equipment.
For a stationary device that supports Ethernet, a network cable is often the most reliable and fastest alternative to troubleshooting a weak wireless connection. It also avoids adding another wireless link to the setup.

Choose the least disruptive fix that solves the problem
Start with tests that cost nothing: compare locations, move the router or client, and try the available bands. If the weak area remains, choose between a wired access point, wireless repeater, or mesh based on your layout and cable options. Upgrade an individual adapter or antenna only when the equipment supports it; use Ethernet for stationary devices when a cable is practical.
