Why Does My Wi-Fi Work in Some Rooms But Not Others?

Steps to fix it

1. Check where your router is physically locatedRouters broadcast in a rough sphere, so a router in a corner, in a basement, or behind a TV stand is already fighting the layout of your house before signal even reaches the far room.
2. Move it to a central, elevated spotA shelf in a central hallway or living room, away from the floor, beats a corner or a closet almost every time.
3. Identify what's between the router and the dead zoneWalls with metal ductwork, brick, concrete, or large mirrors block Wi-Fi far more than drywall. Appliances like refrigerators and microwaves cause real interference too.
4. Switch the affected device to the 2.4GHz band if it's using 5GHz5GHz is faster up close but loses strength through walls much faster than 2.4GHz — if a room is far from the router, 2.4GHz may actually perform better there.
5. Check for interference from neighboring networksIn apartments or dense neighborhoods, several routers can end up broadcasting on the same or overlapping Wi-Fi channel, which quietly degrades performance in specific areas — similar to too many people talking over each other on the same radio frequency. You generally don't need to see or diagnose exactly which networks are overlapping; the practical fix is simply to try changing your own channel. Log into your router's admin page (usually 192.168.1.1 or 192.168.0.1 in a browser, or via its app), go to the Wireless or Channel settings section, and if the 2.4GHz channel is set to "Auto," manually try setting it to channel 1, 6, or 11 specifically — these three don't overlap with each other and are the standard recommendation. Save and give it a few minutes, then check the dead zone again.
6. Consider a mesh system or a single well-placed extenderIf the dead zone remains after placement and channel changes, added hardware is the next real fix — see our mesh vs. extender comparison (linked from the homepage under Guides, or just click through from here) for which fits your situation.
