How to extend WiFi range? Summary of popular solutions across the network in the past 10 days
With the popularity of remote working and smart homes, the issue of WiFi signal coverage has become a hot topic on the Internet recently. The following is an efficient solution compiled based on hot discussions across the Internet in the past 10 days to help you easily expand your WiFi range.
1. Comparison of popular WiFi expansion solutions in 2023
| Plan type | average cost | Operation difficulty | Improved effect | Applicable scenarios |
|---|---|---|---|---|
| Router location optimization | 0 yuan | ★☆☆☆☆ | 20-40% | small apartment |
| WiFi signal booster | 150-300 yuan | ★★☆☆☆ | 50-70% | Medium size |
| Mesh networking system | 800-2000 yuan | ★★★☆☆ | 100-300% | Large apartment/villa |
| Power cat solution | 400-800 yuan | ★★☆☆☆ | 60-90% | Difficulties in wiring old houses |
2. Golden rules for router placement (recent tips on Douyin/Xiaohongshu)
1.central high position principle: Place the router 1-1.5 meters away from the ground, away from interference sources such as metal cabinets and microwave ovens.
2.Antenna Orientation Tips: Most routers use omnidirectional antennas, and the horizontal signal is best when placed vertically. For dual-band routers, it is recommended to separate the 2.4GHz and 5GHz antennas at an angle of 45 degrees.
3.Signal dead end cracking: Use mobile APP (such as WiFi Analyzer) to detect signal strength. Areas above -70dBm are high-quality coverage areas.
3. Selection of hardware upgrade solutions (data from JD/Tmall best-selling list)
| Product Category | Hot selling models | Coverage area | Key technologies |
|---|---|---|---|
| Mesh router | TP-Link Deco X68 | 200㎡ | Tri-band backhaul |
| WiFi6 amplifier | Huawei AX3 Pro | 120㎡ | 160MHz bandwidth |
| Power cat suit | Tenda PH15 | 150㎡ | G.hn technology |
4. Software optimization skills (latest actual test by Bilibili Technology UP Master)
1.Channel optimization: Use tools such as WiFi Magic Box to scan surrounding channel occupancy and avoid the congested 1/6/11 channels (2.4GHz frequency band).
2.Firmware upgrade: In August 2023, mainstream manufacturers (ASUS/Netgear, etc.) have released signal optimization firmware, which can improve wall penetration performance by more than 15%.
3.Frequency band allocation: Smart home devices are bound to the 2.4GHz frequency band, and mobile phones/tablets give priority to using the 5GHz frequency band to avoid mutual interference.
5. Future trends: What changes will WiFi 7 bring?
According to a recent industry white paper, WiFi 7 (802.11be), which is about to be commercialized, will bring:
-coverage improvement: MLO multi-link technology enables concurrent transmission of multiple frequency bands
-Enhancement through walls: 4096-QAM modulation technology improves edge signal quality
-Delay reduced: The expected delay is reduced from 20ms for WiFi6 to less than 5ms.
It is recommended that when purchasing equipment at this stage, you should give priority to products that support WiFi6 to reserve upgrade space for future Mesh networking.
Summary:Expanding WiFi coverage requires a combination of hardware + software + environment optimization. Choose the appropriate solution based on the house area and budget. For ordinary families, it is recommended to start with a WiFi signal amplifier that costs about 200 yuan. Duplex/villa users can directly consider the Mesh system. Regularly checking channel occupancy and device firmware versions will allow your existing network to perform optimally.
