## FAQ

### What is the difference between 2.4 Ghz and 5 Ghz Wi-Fi?
The difference is the radio frequency band used for transmission, where 2.4 Ghz offers longer range through walls while 5 Ghz provides faster speeds over shorter distances.

### Which is better, 2.4 Ghz or 5 Ghz?
5 Ghz is better for speed-sensitive tasks like streaming and gaming near the router, while 2.4 Ghz is better for coverage across larger homes or through solid obstacles.

### Does 5 Ghz cost more than 2.4 Ghz?
No, 5 Ghz does not cost extra because both bands are included free on modern dual-band routers, so your internet bill remains identical regardless of which band you use.

### Is 5 Ghz Wi-Fi safe for your health?
Yes, 5 Ghz Wi-Fi is safe because it emits non-ionizing radio waves at power levels far below international safety limits set by organizations like the FCC and WHO.

### Which devices are compatible with 5 Ghz but not 2.4 Ghz?
Newer smartphones, laptops, and smart TVs support 5 Ghz, but older IoT devices like basic smart plugs and some security cameras only support 2.4 Ghz due to cheaper hardware.

### Why does my device only see 2.4 Ghz and not 5 Ghz?
Your device only sees 2.4 Ghz because its Wi-Fi adapter lacks 5 Ghz support or because your router broadcasts a single combined network name that hides the 5 Ghz band.

### Can I use 2.4 Ghz and 5 Ghz interchangeably?
No, you cannot use them interchangeably because each device must connect to a band its hardware supports, and switching bands requires manually reconnecting to a different network name.

### When should I use 2.4 Ghz instead of 5 Ghz?
Use 2.4 Ghz when your device is far from the router, separated by walls, or when you need reliable coverage for basic browsing and smart home gadgets.

### Can I switch from 5 Ghz to 2.4 Ghz on my phone?
Yes, you can switch by opening your Wi-Fi settings and selecting the 2.4 Ghz network name, provided your router broadcasts both bands under separate names.

### Is 2.4 Ghz better for gaming than 5 Ghz?
No, 5 Ghz is better for gaming because it delivers lower latency and higher data rates, while 2.4 Ghz suffers from more interference from microwaves and Bluetooth devices.
