Slow Wi-Fi can come from the internet line, router processing, radio congestion, distance or one particular device. Isolating the layer prevents unnecessary changes.
Establish a Baseline
Run a wired speed test near the router, then compare it with Wi-Fi tests at close and normal distances.
Improve Router Placement
Use an open, central, elevated position away from metal, thick walls, microwaves and crowded electronics.
Choose the Right Band
Use 5 GHz or 6 GHz for speed at shorter range and 2.4 GHz for reach through walls.
Reduce Congestion
Restart affected devices, pause large downloads, update firmware and choose a cleaner Wi-Fi channel where manual control is available.
Know When to Upgrade
Older standards, weak processors and insufficient coverage can limit performance even on a fast broadband plan.
Frequently asked questions
Why is Ethernet fast but Wi-Fi slow?
That points to wireless signal, interference, channel or device limitations rather than the ISP line.
Will a Wi-Fi extender increase speed?
It can improve a weak area, but placement and backhaul quality determine the result.
Does restarting help?
It can clear temporary faults, but repeated slowdowns require diagnosis.
