Most people accept their WiFi as-is and assume poor performance is just what WiFi is like. Most poor WiFi is fixable with settings changes and physical placement.

Router placement: the router should be central, elevated, away from walls and metal objects. Not in a cupboard. Not on the floor. Not behind the TV. Each of those locations reduces range and speed significantly.

Change your WiFi channel. Most routers default to auto channel selection which often lands on the same congested channel as your neighbours. Download WiFi Analyzer on Android and look for the least used channel on both 2.4GHz and 5GHz. Set your router to those channels manually.

Split your 2.4GHz and 5GHz networks if your router combines them. Give them different names and connect devices deliberately. Use 5GHz for devices near the router that need speed. Use 2.4GHz for far-away smart home devices that need range over speed.

Update your router firmware. Manufacturers release firmware updates that improve performance and fix bugs. Most routers have an auto-update option buried in settings that is off by default.

Enable QoS if your router supports it and prioritise your work machine or gaming device so it gets bandwidth first when the network is busy
RTFM and then ask

The channel change tip is the one that made the most difference for me. My router was on channel 6 alongside four neighbours. Switching to channel 11 gave me a 40 percent speed increase immediately

Router placement in a cupboard is the mistake I see most often when helping friends with WiFi problems. The cupboard kills signal. Moving it to a shelf in the hallway fixes it immediately

Splitting 2.4 and 5GHz is underrated advice. Having them on the same SSID sounds convenient but devices often connect to 2.4GHz when they should be on 5GHz and vice versa. Explicit control is better

Powerline adapters as an alternative to WiFi for devices that are far from the router but near a power socket are underused. Not as fast as ethernet but significantly more reliable than weak WiFi

The firmware update tip is the most ignored. I checked my parents router recently and it was on firmware from 2021. The current version had 15 security patches and three performance improvements

For anyone in a flat or dense urban area 5GHz channel congestion has also become a real issue now. The 5GHz band used to be uncrowded. WiFi 6 routers on the 6GHz band are the next step if channel congestion is the issue on both bands

QoS configuration on ISP-provided routers is often very basic. On a third party router running OpenWrt or DD-WRT it is much more granular and effective

The phone WiFi Analyzer recommendation is excellent. Seeing the channel landscape visually makes the channel selection decision immediately obvious rather than guessing

If you have tried everything and WiFi is still unreliable in specific rooms, a mesh WiFi system is the hardware upgrade that actually solves coverage problems rather than working around them
