How to Improve Wi-Fi Signal at Home

Wi-Fi is weak in part of the home, or drops out. Most of the fix is placement; the rest is settings and, for big homes, more hardware.

Move the router

Put it in the middle of the home, up high on a shelf or desk, and out in the open. A router in a cabinet, closet, basement corner, or behind a TV loses a large share of its range. Keep it away from microwaves, cordless phone bases, fish tanks, mirrors, and large metal objects like fridges, all of which block or interfere with the signal. If the provider's line enters at one end of the home, a longer cable to move the router is worth it. Point external antennas upward.

Use the right band

Modern routers broadcast on 2.4 GHz and 5 GHz, and some add 6 GHz. 5 GHz is much faster but has shorter range and struggles through walls. 2.4 GHz is slower but reaches further. Near the router, connect to the 5 GHz network. In far rooms, 2.4 GHz often holds a steadier connection. If the router shows one combined name, it picks for you; if it shows two names, choose by location.

Change the channel

In apartments, neighboring networks crowd the same channel. Log in to the router, open the wireless settings, and set the channel to Auto if it is fixed, or pick a less busy one: 1, 6, or 11 on 2.4 GHz. A free app such as WiFi Analyzer on Android shows which channels nearby networks use.

Update the firmware and restart

Firmware updates fix stability bugs. See update your router firmware. Then restart the router: unplug it for 30 seconds and plug it back in. Do this any time the connection has slowed over a period of weeks.

Add a mesh system or extender

If the home is large or has thick walls, one router cannot cover it. A mesh system, two or three units sharing one network name, is the reliable fix. A cheaper extender helps one room. Place the second unit about halfway between the router and the weak area, where the signal is still strong, not in the dead zone itself.

If the router is more than 5 or 6 years old. It is likely the limit. A current Wi-Fi 6 or Wi-Fi 7 router or mesh kit outperforms an old one from the same spot.

If some devices never move. Run an Ethernet cable to the TV, console, or desktop. Every device taken off Wi-Fi frees airtime for the ones that need it.
