Fix placement first

Place the router or access point in an open, elevated, reasonably central location. Avoid cabinets and large metal objects.

Test the weak areas

Walk through the home and test where signal drops. This helps determine whether the issue is coverage, interference, or internet service itself.

Use the right band

2.4 GHz usually reaches farther, while 5 GHz and 6 GHz can offer more speed at shorter range. The best choice depends on distance and obstacles.

When mesh helps

Mesh systems can help larger homes, but placement still matters. Too much distance between nodes can reduce performance.

When a wired access point is better

If Ethernet can be run, a wired access point often gives more consistent performance than a wireless extender.
