There's an important difference between the speed coming into your home and the speed your laptop or phone actually receives over Wi-Fi. You can pay for a fast plan and still get sluggish Wi-Fi if something inside your home is the bottleneck. The good news: most Wi-Fi problems are fixable.
Where your router sits matters
Wi-Fi signal weakens with distance and obstacles. A router tucked in a closet, on the floor, or in a far corner will deliver weaker speeds to the rest of the home. Place it centrally, elevated, and out in the open for the best coverage.
Your router's age and capabilities
- Older routers may not support the speeds your plan provides.
- Modern standards (like Wi-Fi 6/6E) handle more devices at once more efficiently.
- A single router may struggle to cover a large or multi-story home — a mesh system can help.
Interference and congestion
Walls, large appliances, and even neighboring networks can interfere with Wi-Fi. The 2.4 GHz band reaches farther but is slower and more crowded; the 5 GHz band is faster but has shorter range. Many devices choose automatically, but knowing the trade-off helps you troubleshoot.
The device itself
An older phone, tablet, or laptop may simply not be capable of high speeds, no matter how fast your plan is. When testing, compare results across multiple devices and, where possible, a wired connection.
Quick troubleshooting checklist
Restart your router, move it to a central spot, connect on the 5 GHz band when close, update firmware, and test with a wired connection to isolate whether the issue is your Wi-Fi or your plan.
