WiFi tool
Channel Reference
Pick a band to see every WiFi channel and its centre frequency. The 2.4 GHz list notes the non-overlapping channels, the 5 GHz list marks DFS channels, and the 6 GHz list covers WiFi 6E and 7.

Accepted input
- A band selection: 2.4 GHz, 5 GHz, 6 GHz, or all bands combined.
Limits
- Frequencies are centre channel frequencies in MHz.
- Regulatory rules vary by region; the notes flag DFS and Japan-only cases.
Local processing
- The reference data is built into the page. No request is made when you list channels.
How to use Channel Reference
- Pick a band from the selector.
- Press List channels to build the table.
- Download the CSV to keep the list, or read it on the page.
What it does
- Covers 2.4 GHz (channels 1-14), 5 GHz (36-165) and 6 GHz (1-233).
- Flags DFS channels on 5 GHz and notes region-specific rules such as channel 14.
- Outputs CSV that opens in any spreadsheet app.
Limits and things to know
- List reflects standard channel numbering; some regions restrict which channels are legal.
- Channel bandwidth (20, 40, 80, 160 MHz) is not part of the table.
Example
Choosing a 5 GHz channel
List the 5 GHz band and look for channels in UNII-3 (149-165) because they do not require DFS. Pick 161 for a 40 MHz network that does not conflict with radar.
Frequently asked questions
What is a DFS channel?
Dynamic Frequency Selection channels (52-144 on 5 GHz) must yield to radar. Your access point listens for radar and changes channel if it hears any, which can drop clients.
Why are 6 GHz channels spaced 5 MHz?
The 6 GHz band uses the same 5 MHz grid as older bands. Channels 1-93 are typically reserved for standard-power use that requires an AFC check.
Which channel should I pick?
For 2.4 GHz, use 1, 6 or 11. For 5 GHz, prefer 36-48 or 149-161 to avoid DFS. For 6 GHz, any channel your devices support works because the band is still lightly used.
