What should I do if the WiFi signal in the living room is weak? Summary of popular solutions across the network in 10 days
Recently, the issue of home WiFi signal coverage has once again become the focus of heated discussions on the Internet. Many users have reported that signals in large areas such as living rooms are weak and network speeds are slow, affecting the experience of watching movies and gaming. This article combines popular discussions and technical posts across the Internet in the past 10 days to sort out the following structured solutions to help you quickly optimize your network environment.
1. Analysis of Common Reasons for Weak WiFi Signals

| Reason type | Specific performance | Proportion (sampled data) |
|---|---|---|
| Router improperly positioned | Stay away from the living room or blocked by obstacles | 42% |
| Equipment is old | Support protocols are lagging (e.g. only 802.11n) | 28% |
| Frequency band interference | There are too many devices on the same frequency as 2.4GHz | 18% |
| Insufficient bandwidth | Multiple devices online at the same time | 12% |
2. Comparison of popular solutions
| method | Operation difficulty | cost | Performance rating |
|---|---|---|---|
| Adjust router position | ★☆☆☆☆ | 0 yuan | ★★★☆☆ |
| Upgrade your WiFi 6 router | ★★☆☆☆ | 300-1000 yuan | ★★★★☆ |
| Install signal amplifier | ★★★☆☆ | 50-200 yuan | ★★★☆☆ |
| Mesh networking | ★★★★☆ | 500-2000 yuan | ★★★★★ |
| Change operator plan | ★☆☆☆☆ | Increase in monthly rent | ★★☆☆☆ |
3. Step-by-step optimization guide (high-heat plan)
1. Router location adjustment
•Centralization principle:Move the router to the center of the living room, avoiding obstacles such as metal cabinets and load-bearing walls.
•Highly recommended:Place it at a height of 1-1.5 meters (such as a TV cabinet) to avoid stacking on the ground.
•Antenna angle:If it is an external antenna, adjusting it to a 45° tilt can improve horizontal coverage.
2. Frequency band optimization (5GHz priority)
• Log in to the router's backend (usually 192.168.1.1) and turn off the "dual-band-in-one" function.
• Separate connection to the 5GHz band for living room devices (weak through walls but less interference).
• For 2.4GHz channels, it is recommended to manually select non-overlapping channels such as 1/6/11.
3. Low-cost enhancement solution
•Aluminum foil reflection method:Use tinfoil to make a curved reflective plate and place it behind the router to enhance the signal in a direction (measured increase is 15%-20%).
•Firmware upgrade:Check the manufacturer's official website for updates. The new firmware may optimize the signal algorithm.
4. Advanced solution: Key points of Mesh networking configuration
| Brand | Recommended models | Coverage area (single node) | Networking suggestions |
|---|---|---|---|
| TP-Link | Deco X55 | 80-100㎡ | 2 nodes cover three bedrooms and one living room |
| Huawei | AX6 | 90-120㎡ | Support wired backhaul for more stability |
| Xiaomi | AX3000 | 60-80㎡ | Best value for money |
5. Operator-related complaints and suggestions
If it is confirmed that it is not an equipment problem, you can:
1. Call customer service and ask to "test the light attenuation value" (normal should be ≤-27dBm);
2. Apply to replace the Gigabit optical modem (some old communities still use 100M equipment);
3. Feedback long-term unresolved signal issues through the Ministry of Industry and Information Technology’s complaint channel.
Summary:According to the actual measurement data of the entire network,Mesh networkingwithRouter location adjustmentIt is an effective solution that has been the most discussed recently. It is recommended to try zero-cost optimization methods first, and then choose hardware upgrades based on budget. If the problem persists, you need to check whether it is a quality problem with the broadband itself.
