how to fix weak wifi signal

Bars on a phone are a rough hint. A room with one bar can still load mail, and a room with full bars can still stutter on a call. Here is how to fix weak wifi signal in the order that solves the most homes.

Move the router before you buy anything

Put it in the open, about chest height, near the center of the area you use. A closet, a TV cabinet, and the floor behind a sofa all swallow the signal. Keep it off the microwave, the baby monitor, and a thick fish tank. Antennas, if you have them, should point up. Then test internet speed in the weak room and next to the router. If the router room is already slow, call the provider or check the modem. Extending a slow source does not help.

Use the right band

5 GHz and 6 GHz are faster and shorter. 2.4 GHz travels farther through walls. A laptop that clings to 5 GHz at the edge of the house will look weak. Forget the network and join the 2.4 GHz name, or move a mesh node closer. On a crowded 2.4 GHz band, change the channel to 1, 6, or 11, whichever the neighbors are not using.

Add coverage only where the test says so

• One dead room: a mesh node or extender halfway there.
• A desktop that never moves: an Ethernet cable or a powerline adapter.
• A backyard: an outdoor-rated unit, not an indoor puck in the window.

After each change, test internet speed again in the same chair. You want download and upload to rise and jitter to fall. If nothing moves, the device itself may be the limit. Try a second phone before you replace the router.

Back on your own network, test internet speed in the room that matters and compare download, upload, and jitter.
