 What Is WiFi and Why Does It Stop Working?

Wi-Fi gives us wireless access to the internet using a WiFi router. But despite being extremely convenient, WiFi signals can be affected by distance, interference, outdated hardware, or network overload.

In simple words:

WiFi not working means your device is connected but cannot access the internet — OR the WiFi itself is not functioning.

 Quick Diagnosis: Is It Your Phone, Network, or Internet?

Before applying fixes, identify the real cause:

---

1. Problem in Your Phone (Device Issue)

Your phone may be the reason WiFi is not working if:

• Only your device cannot connect

• Other devices connect normally

• Turning hotspot ON/OFF fixes it for a few seconds

• WiFi keeps disconnecting only for you

👉 In this case, it's a device problem.

---

2. Problem in WiFi Network (Router Issue)

If:

• No device can connect

• WiFi signal shows full but no internet

• Router lights are blinking strangely

👉 It's a router/network issue.

---

3. Problem in Internet Connection (ISP Issue)

If:

• WiFi connects, but internet doesn’t work

• Mobile hotspot or other networks work fine

• Your ISP shows “maintenance” or “outage”

👉 The issue is Internet (ISP) — not your device.

 Most Common WiFi Problems

These are the top problems users face when wifi not working:

✔ Slow WiFi speed
✔ WiFi dropping randomly
✔ WiFi network not visible
✔ Weak WiFi signal
✔ Router not connecting to the Internet
✔ Too many devices connected
✔ ISP outage

Now let’s fix them one by one…

---

 Fix 1 — Check If Your Phone Is Causing the Issue

Sometimes the simplest problems create the biggest frustration.

✔ Restart your phone

This resets WiFi hardware.

✔ Forget and Reconnect to WiFi

Go to Settings → WiFi → Tap Network → Forget

✔ Reset Network Settings

Settings → System → Reset → Network Reset
(This removes saved WiFi and Bluetooth, but fixes major errors)

✔ Turn Airplane Mode ON, wait 10s, turn OFF

If WiFi works fine on other devices but not yours → it’s a phone issue.

---

 Fix 2 — Check Your Router (Most Common Fix)

Router issues cause 70% of “wifi not working” problems.

✔ Restart the Router

Unplug → wait 10 seconds → plug back.

✔ Check Router Lights

• Green/Blue: working

• Red/Orange: problem

✔ Ensure Cables Are Tight & Not Damaged

✔ Try Connecting With LAN Cable

If LAN works but WiFi doesn’t → router WiFi issue.

---

 Fix 3 — Check Your Internet (ISP) Connection

Your WiFi may be fine but the internet is down.

✔ Test Internet From Mobile Hotspot

If hotspot works → ISP problem.

✔ Log in to ISP dashboard (if available)

Check outage alerts.

✔ Call ISP helpline

Ask: “Is there a service outage in my area?”

---

 Fix 4 — Fix Slow WiFi Speed

Slow speeds are one of the most common WiFi problems.

Causes:

• Distance from router

• Interference from other devices

• Old router

• Too many devices

• Outdated firmware

Solutions:

• Place router centrally

• Keep router away from walls

• Don’t keep router near microwave or Bluetooth speakers

• Update router firmware

• Use 5GHz band for faster speed

• Remove devices connected unnecessarily

---

 Fix 5 — Fix Intermittent WiFi Drops

Random disconnects feel the most irritating.

Causes:

• Overloaded network

• Interference

• Heat in router

• Background apps

Solutions:

✔ Change WiFi channel
✔ Disconnect unused devices
✔ Restart router
✔ Keep router in open space
✔ Disable VPN temporarily

---

 Fix 6 — WiFi Network Not Showing

If your WiFi name is not visible:

Causes:

• SSID broadcast disabled

• Router malfunction

• Distance too far

• Power fluctuation

Solutions:

✔ Enable SSID broadcast (in router settings)
✔ Restart router
✔ Reset router to factory mode
✔ Move closer to the router

---

 Fix 7 — Fix Weak WiFi Signal

Weak signals = poor connection.

Causes:

• Thick walls

• Metal objects

• Floors/walls blocking signal

• Router positioned low

Solutions:

✔ Use WiFi extender
✔ Use mesh WiFi system (best for large homes)
✔ Place router higher (like top shelf)
✔ Keep router in central position

---

 Advanced Tips to Improve WiFi Performance

 Use 5GHz for streaming & gaming

Faster, short-range, stable.

 Use 2.4GHz for long range

Slower but covers more distance.

 Update router every 2 years

Old routers cannot handle modern devices.

 Limit smart home devices

They overload networks quickly.

Distance, router age, interference, ISP speed, or too many devices.
