Have you noticed that your laptop's Wi-Fi signal has gotten worse, even though it used to work reliably? Or is the signal constantly dropping out in certain rooms, even though your phone and tablet are connected without a problem? Weak Wi-Fi on laptops is a more common issue than you might think—and the router isn't always to blame. In 70% of cases, the culprit is outdated drivers, incorrect power saving settings or physical interference.
In this article we will look at all possible reasons poor Wi-Fi reception on laptops running Windows 10/11, macOS and even Linux — from basic settings to hardware modifications. You will learn how Increase connection speed and stability by 30–50% without purchasing new equipment, as well as when it's really worth considering replacing your Wi-Fi adapter. All methods have been tested on laptops. Lenovo ThinkPad, HP Pavilion, Asus ROG And MacBook Pro (2018–2026).
Spoiler: If your laptop is older than 5 years, the problem may be in hardware - modern standards Wi-Fi 6/6E require support 802.11ax, which is missing from older adapters. But even in this case, there are solutions!
1. Check the obvious: router and physical interference
Before you dig into your laptop's settings, make sure the problem isn't with your router. 50% of complaints about "bad Wi-Fi" are resolved with a simple router reboot. or changing its location.
- 🔌 Reboot your routerUnplug it for 30 seconds, then plug it back in. This will clear the DHCP cache and any temporary errors.
- 📡 Change the placeThe router should be located in the center of the apartment, 1–1.5 meters above the floor. Avoid placing it near microwaves, wireless speakers, and mirrors.
- 📶 Change Wi-Fi channel: If there are many networks nearby, they can “jam” each other. Use apps like WiFi Analyzer (Android) or NetSpot (Windows/macOS) for channel load analysis.
If after these steps the signal on your laptop hasn't improved, but it has improved on your phone, the problem is definitely with the laptop. If the Wi-Fi is poor on all devices, the router or ISP is to blame.
