SwiftNetScanHow to Improve WiFi Speed at Home
WiFi performance problems are frustrating — but most can be resolved without buying new equipment. Work through these steps before spending any money.
1. Optimize Router Placement
The most impactful free change: move your router to a central, elevated location away from thick walls, metal objects, and appliances. WiFi signals weaken significantly with each wall and floor they pass through. A router in the corner of your basement serves almost no one well.
2. Switch to the 5 GHz Band
2.4 GHz is slower and more congested (shared with microwaves, Bluetooth, neighbors' networks). For devices near the router, 5 GHz delivers 2–3× higher speeds. Connect close devices to 5 GHz; keep distant devices on 2.4 GHz.
3. Change Your WiFi Channel
Use a WiFi analyzer app to identify the least-used channels in your area. For 2.4 GHz, use channels 1, 6, or 11 only (the non-overlapping options). Log into your router's admin panel to change channels.
4. Update Router Firmware
Log into your router admin panel and check for firmware updates. Manufacturers release updates that fix performance bugs and improve memory management. Enable auto-updates if available.
5. Reduce Connected Devices and Background Activity
Review all connected devices in your router admin panel. Disconnect inactive devices. Disable auto-updates on smart TVs and gaming consoles during peak hours. Each device consumes router processing capacity even when idle.
When Hardware Upgrades Are Necessary
If your router is 5+ years old or you live in a home larger than 1,500 sq ft, hardware improvements will help. A WiFi 6 router handles multiple devices dramatically better. A mesh system eliminates dead zones.

- Powerline adapters to extend wired connectivity to hard-to-reach rooms
Frequently Asked Questions
Does distance affect WiFi speed?
Significantly. WiFi signal strength decreases with distance and obstacles. At 10 meters through a wall, you may have 50% of the speed you'd get at 1 meter in the same room.
Will a WiFi extender improve my speed?
A WiFi extender increases range but typically halves the bandwidth to devices connected through it (it must receive and retransmit on the same channel). A mesh system is a better solution as dedicated backhaul links avoid this penalty.
How can I check my WiFi signal strength?
On Windows, hover over the WiFi icon for signal bars, or open Command Prompt and run 'netsh wlan show interfaces' for the exact signal in dBm. On Android, a WiFi analyzer app shows signal strength in dBm.
