The causes for this vary, but here are remedies to try once you’re on a Wi-Fi router’s setup screen, usually accessed by typing 192.168.1.1 into the browser of a computer on that network:
- Shut off 802.11b WiFi if it’s on, as this obsolete variant will only slow down your network.
- If you live in a smaller space, try switching to 5 GHz WiFi should your router and your devices support it — most reasonably new models do. This lacks the range of standard 2.4 GHz WiFi but is faster and less prone to interference.
- • Moving the router to a more central spot often helps too.
