Start With a Three-Step Triage
Note on sources: specific speeds, standards, equipment specs, and prices were not verified in this research stage and will be cited before final publication. Treat every step as conditional troubleshooting, not a guaranteed fix.
Run this quick triage before you change anything; it costs nothing and takes about ten minutes.
- Power-cycle the router and modem. Unplug both, wait a minute or two, plug the modem back in, then the router, and let everything reconnect before testing.
- Update the router firmware. Open the router's admin page and look for a firmware, software, or update option. Menu names and steps vary by brand and model, so keep the router's manual handy.
- Check how many devices are connected. The admin page usually shows a device list; if it is long, disconnect idle devices and retest the dead zone.
If you cannot find the admin page, look for the login address on the router or in its manual or support page.
Give the Router a Better Spot Before Replacing It
Placement is often the cheapest fix, because the signal must travel through walls, floors, and objects to reach the room where you stream or join video calls. Every wall and obstacle can weaken that journey, so a shorter, clearer path gives the best chance of a reliable connection.
Try these placement checks in order:
- Move the router toward the center of the home, away from corner closets and behind-the-TV hiding spots.
- Raise it onto a shelf or tabletop instead of the floor.
- Keep it clear of thick walls, metal objects, fish tanks, and large appliances.
- Retest the problem room after each move so you know which change helped.
If moving the router is not practical because the cable outlet is fixed in a corner, skip ahead to the band check before spending anything.
Check Which Band Your Devices Are Using
Most home routers broadcast on more than one band, commonly labeled 2.4 GHz and 5 GHz, though names vary by brand. Switching bands is a free experiment: open the router admin page, look for band or frequency settings, then check which network name your phone or laptop is connected to. Some routers put both bands under one name; others list them separately.
Why try this before buying anything? In many homes the two bands can perform very differently depending on distance, walls, and device age, so the band that works well in one room may struggle in another. There is no universal rule that fits every house, so the only way to know is to switch bands and retest. Reconnect after switching, then test the dead zone again.
When Free Fixes Are Not Enough: A Decision Framework
If the free steps above do not remove the dead zone, use this decision flow before looking at products.
- One small dead zone near the router? Recheck placement and bands once more; small gaps sometimes disappear with a one-time adjustment.
- One room or basement that stays dead? This is the typical situation where an extender, mesh system, or powerline adapter is worth researching, because the signal must cross distance, walls, or floors.
- Weak signal everywhere, even close to the router? The problem may be the connection coming into the home, not your Wi-Fi equipment, so test that before buying gear (next section).
- Renting your home? Check what the lease or landlord allows before installing anything that needs configuration or stays plugged in.
Important: exact prices, coverage numbers, and performance specs were not verified for this page and vary by retailer, vendor, and home. Before buying, read the vendor's current documentation on coverage, setup effort, and compatibility with your router and internet plan. Treat any speed number as a starting point, not a guarantee.
Is the Problem Your Router or Your Internet Service?
The fastest way to separate a router problem from an internet service problem is a wired-versus-Wi-Fi test.
- Plug a laptop directly into the modem or router with an Ethernet cable.
- Run an online speed test while wired.
- Unplug the cable, move to the problem room, and run the same test over Wi-Fi.
- Compare the results, and repeat at different times of day before drawing conclusions.
Treat the results as clues rather than guarantees:
- Wired test much stronger than the Wi-Fi test in the dead zone: the router, its placement, or its settings are the likely bottleneck, so keep working on the free fixes.
- Both tests weak: the issue may sit with the internet service, the modem, or the wiring inside the home, so the ISP is the next call.
- Results that bounce around: run the tests over several days before deciding anything.
Internet service quality and availability vary by US address and region. A neighbor's experience is not a reliable predictor of yours, and rural areas can differ sharply from cities, so treat your own repeated tests as the only meaningful data.
Recap: Your No-Purchase Checklist
Here is the plan in five short steps:
- Power-cycle the modem and router, update firmware, and trim the connected-device list.
- Move the router central, elevated, and clear of obstacles; retest each step.
- Switch bands and retest before considering any purchase.
- Run wired and Wi-Fi speed tests to separate ISP issues from router issues.
- Only if free fixes fail, compare equipment documentation or call your ISP.
When Free Fixes Fail: Call the Right People
If the dead zone remains after this plan and the ISP has checked the connection, the next step is a site-specific conversation: ask the ISP's technician or a qualified home-network installer to look at your actual layout, walls, and wiring.
No generic article can promise that any single fix will work in your home, because construction, furniture, device mix, and service quality all vary. That is why this page avoids product prices, speed claims, and guarantees.
