WiFi Troubleshooting and Optimisation Guide

Top 5 Quick WiFi Fixes

1. Make sure WiFi is turned on (and Airplane Mode is off).

2. Connect to the right WiFi network (Zeronet or your router’s SSID).

3. Double-check your WiFi password (it’s case-sensitive).

4. Restart your modem/router and your device.

5. Test another device — if it works, the issue may be with your device.

Step 1: Verify WiFi is turned on

Sometimes WiFi gets switched off by mistake.

• Windows: Open Network & Internet settings and make sure WiFi is On and Airplane Mode is Off. Some laptops also have a WiFi button or switch with a wireless symbol.

• Apple (iPhone, iPad, Mac): Open Settings (or System Settings on Mac) and check that Airplane Mode is Off and WiFi is On.

• Android: Go to Settings, confirm Airplane Mode is Off, and ensure WiFi is On.

Step 2: Connect to the right WiFi network

• Look for your WiFi name in the list of available networks.

• If you have a Zeronet router, your WiFi name will include Zeronet.

• For third-party routers, check the sticker on the bottom of your router for the default WiFi name (SSID).

Step 3: Check your WiFi password

• Make sure the password is typed in correctly — it’s case-sensitive.

• You may see two Zeronet networks. These are two different WiFi bands (2.4GHz and 5GHz). Both use the same password, so you can connect to either one.

Step 4: Test with another device

• Try connecting a different device (like a phone or tablet).

• If other devices connect fine, the issue is likely with your specific device — in that case, check with the manufacturer for support.

Step 5: Try a wired connection

• If possible, plug your device into the router with an Ethernet cable.

• If the wired connection works, then the issue is only with WiFi.

How to Optimise Your WiFi Connection

✅ Place your router in a central, open location in your home.
✅ Keep it off the floor and away from thick walls or large appliances.
✅ Use the 5GHz band for faster speeds when you’re close to the router.
✅ Use the 2.4GHz band for better coverage in larger homes or further away.

What to Avoid (to Prevent Slow WiFi)

❌ Don’t place the router inside cupboards, behind TVs, or under furniture.
❌ Avoid interference from microwaves, cordless phones, and baby monitors.
❌ Don’t overload your WiFi — too many devices streaming at once can slow things down.
