How to fix wifi drops on laptop but not phone?

[RobertVG]

My wifi keeps dropping on my laptop, but it's fine on my phone. I've tried the basic how to fix wifi steps like restarting the router. Is this more likely a problem with my laptop's network adapter or a router setting?

Test one thing at a time and check signal strength when it drops.

Since your phone stays online, the laptop is the likely culprit. Start with updating the wireless driver, disable any power saving for the card, and try switching between 2.4 and 5 GHz networks. If it still drops, test with a USB WiFi adapter to see if the problem follows the laptop hardware.

Because the phone is fine, rule out the router settings. Check the cables to the modem and router, then reboot and verify firmware. Temporarily disable features like QoS, MAC filtering, and guest networks to rule them out. On the laptop, update drivers, turn off power management for the wireless adapter, and try a wired connection to confirm if Ethernet stays stable. Note the times of drops and experiment with a different channel on the router. If you can borrow a USB WiFi dongle, test with that to see if the problem follows the card. If drops persist, you’re likely facing a hardware issue or a stubborn router problem that may need deeper fixes or replacement.

Here's a longer, practical plan you can actually follow. First, confirm whether the problem is the laptop or the network by creating a small test with a wired connection and with another device. If the laptop only drops when connected via WiFi and a wired connection is fine, the issue is almost certainly the laptop or its driver. If the whole network drops on all devices, it's more likely router or ISP side. Then start with the router: inspect the physical layer, check cables, swap the Ethernet cable if you have a spare, reboot and check firmware version and recent changes. Temporarily disable advanced features like beamforming, QoS, or bandwidth throttling; if you have dual-band, try forcing 2.4 GHz only or 5 GHz only to see if one band is more stable. Try changing the channel to a less congested one. If you have a guest network, disable it to rule it out. Next, focus on the laptop: update or rollback the wireless driver; ensure power saving settings do not put the adapter to sleep; test with VPNs or antivirus turned off if they might interfere; try a clean boot to see if software is interfering. Check for interference by moving closer to the router and removing obstacles. Run built in diagnostic tools and ping tests while you reproduce the drops, and collect timestamps. If you can borrow a USB WiFi adapter and the problem goes away, you know the issue is the internal card; if not, you’re looking at router or ISP side and might need a replacement. Document each step and keep notes so you’re not guessing, and consider seeking hands on help if it drags on.
