Problem 1 Slow WiFi in Some Rooms

Cause

• Signal weakens as it passes through walls, floors, or furniture

• Older routers have limited range

Fix

• Move the router to a central, elevated location

• Avoid placing it near metal objects, mirrors, microwaves

• Upgrade to a dual-band router (2.4GHz for range, 5GHz for speed)

• Consider a mesh WiFi system for large homes

Problem 2 WiFi Keeps Dropping or Disconnecting

Cause

• Device moving between weak zones

• Router overheating or firmware issues

• Too many devices connected at once

Fix

• Restart your router and modem

• Update router firmware from the admin panel

• Disconnect unused devices

• Switch to a less crowded WiFi channel (especially on 2.4GHz)

Problem 3 WiFi Is Connected but No Internet

Cause

• ISP outage or DNS error

• Modem and router not synced properly

Fix

• Check if your ISP is down using mobile data or call support

• Reboot both the modem and router (turn off 30 seconds, turn on again)

• Change DNS to Google (8888) or Cloudflare (1111) in router settings or on the device

Problem 4 WiFi Is Fast on One Device but Slow on Another

Cause

• Older devices may not support higher speeds

• Device connected to 24GHz instead of 5GHz

• Background apps using bandwidth

Fix

• Check which WiFi band the device is connected to

• Close or pause unnecessary background apps and downloads

• Forget and reconnect the network

• Run a speed test and compare across devices

Problem 5 WiFi Cuts Off at Night or During Video Calls

Cause

• Router schedules or parental controls enabled

• Bandwidth is used heavily by others at home (e.g. streaming, gaming)

Fix

• Log into router admin and disable any automatic shutoff timers

• Use Quality of Service (QoS) settings to prioritize video or work apps

• Talk to family members about shared usage

• Upgrade to a higher bandwidth plan if needed

Extra Tip Monitor Your Network

Install apps like:

• Fing or NetX (for Android/iOS): shows who is connected

• Speedtest: checks actual speed and ping

• Router apps (e.g. TP-Link Tether, ASUS Router): manage devices and security

Bonus Advice Reboot Regularly

• Restart your router at least once a week

• Use a smart plug to schedule auto-restarts at night when not in use

Summary

Most WiFi problems at home can be solved with better router placement, regular maintenance, and simple settings changes.
Understanding the cause is the first step to fixing the frustration.
