Wi-Fi Channel Frequency Table

📖 Tool Introduction

The Wi-Fi Channel Frequency Table is an offline reference tool built for home networking enthusiasts, low-voltage engineers and operations staff. Many people complain that their home Wi-Fi is weak and slow, but the real cause is rarely a bad router: it is far more often that every router on the same street sits on the same crowded channel and they jam each other. This tool lays out channels 1 through 14 on 2.4 GHz and the common 5 GHz channels 36, 40, 44, 48, 52, 56, 60, 64, 149, 153, 157, 161 and 165 in a clean table, showing each channel's center frequency, recommended bandwidth and regional notes at a glance. Recommended non-overlapping channels are highlighted in blue, and a short advice box below explains why 2.4 GHz should stick to channels 1, 6 and 11 while 5 GHz channels naturally do not overlap. Every figure is embedded in the page: no network request is made, so the table works on intranets and disconnected laptops whenever you need it. It is the kind of quick lookup you want open on a second screen while you log into your router admin panel and tweak the wireless settings, because guessing channel numbers from memory almost always lands you on the same congested channel your neighbors already use. The difference between a well-planned and a badly planned wireless network is often just picking the right three channels on 2.4 GHz and keeping them apart from the access points installed next door. This table gives you the exact numbers you need without making you search through regulatory documents or router manuals, and the highlighted picks remove all doubt about which channels are safe to use.

✨ Key Features

• Dual-band switching: one tap on the top tabs flips between 2.4 GHz and 5 GHz and refreshes the table instantly
• Full channel coverage: 2.4 GHz lists channels 1-14, and 5 GHz lists all common indoor and outdoor channels
• Highlighted picks: recommended non-overlapping channels are tinted blue for quick recognition
• Regional notes: DFS radar-avoidance channels and Japan-only channels are clearly labelled
• Selection advice: a practical paragraph under each band explains how to plan your channels
• Table export: copy the table as text or download it as a CSV file for your records

📝 How to Use

1. Open the page and the 2.4 GHz table appears by default, with recommended channels highlighted
2. Tap the 5 GHz tab on top to switch to the 5 GHz channel list
3. Check the center-frequency column for exact frequencies and the notes column for regional and DFS limits
4. Read the advice box below to understand how to choose channels for a home or office network
5. Click Copy table or Download CSV to save the reference locally for offline use

⚠️ Notes

• Regional rules: allowed channels differ by country and region; confirm local regulations before configuring your router
• DFS channels: channels 52-64 use dynamic frequency selection and must be vacated when radar signals appear
• Channel 14: this channel is open only in parts of Japan and is usually invisible elsewhere
• Bandwidth trade-off: enabling 40 MHz or 80 MHz channel width occupies several adjacent channels and worsens overlap
• Offline reference: this table is a standard reference; actual available channels depend on your router and local law
