Most home Wi‑Fi is either 2.4 GHz, 5 GHz, or both, and you can check the band from your device or router settings.

Quick name check

Many routers put the band in the network name (SSID).

• If your Wi‑Fi name ends with things like “2.4”, “2G”, “24G”, that one is 2.4 GHz.

• If it ends with “5”, “5G”, or “5GHz”, that one is 5 GHz.

If you only see one name with nothing added, it could be either, so use the methods below.

On an Android phone

• Connect to your Wi‑Fi.
• Go to Settings → Wi‑Fi (or “Network & internet” → Wi‑Fi), tap your connected network, and look for “Frequency” or “Band”.

• It will explicitly say 2.4 GHz or 5 GHz.

On an iPhone

Recent iOS versions do not show the band directly in Wi‑Fi settings, so you have two options.

• Use Apple’s AirPort Utility app with Wi‑Fi scanning enabled, which shows each network and its channel/band (channels 1–14 are 2.4 GHz; 36–165 are 5 GHz).

• Or log into your router’s web page (see next section) from the iPhone’s browser and read the Wi‑Fi band there.

On a Windows PC

• Connect to your Wi‑Fi.
• Click the Wi‑Fi icon → click your connected network → Properties (or “Network & Internet settings” → Wi‑Fi → your network → Properties).
• Find “Network band” or “Frequency”; it will say 2.4 GHz or 5 GHz.

On a Mac

• Connect to your Wi‑Fi.
• Hold the Option (Alt) key and click the Wi‑Fi icon in the menu bar.

• In the details that pop up, look for “Channel”:
  • Channel 1–14 → 2.4 GHz
  • Channel 36–165 → 5 GHz

Checking in the router

If you can sign in to your router’s admin page (type its IP like 192.168.0.1 or 192.168.1.1 into a browser and log in), look under Wireless/Wi‑Fi settings.

• It will list each SSID and clearly mark whether it is 2.4 GHz or 5 GHz.
• Many routers show both bands; you can see which one matches the name you connect to.
