Mac can't see or join a 6 GHz Wi-Fi network

6 GHz needs a Mac and a router that both support Wi-Fi 6E or Wi-Fi 7, and WPA3 security. A Mac also finds 6 GHz networks in a different way from 2.4 and 5 GHz networks.

Fix this with your agentCopies a prompt for Claude Code, Codex or any agent that can use Terminal.

My Mac has this problem: Mac can't see or join a 6 GHz Wi-Fi network. Read https://kilobat.app/guides/mac-cant-see-6ghz-wifi.md and work through it with me. Install the Kilobat CLI if it’s missing: brew install seifip/kilobat/kilobat. Run the guide’s Terminal and kilobat checks yourself and tell me what you find. List the steps only I can do. Ask before you change any setting.

Symptoms

The 6 GHz network does not show in the Wi-Fi menu.
The Mac always uses 5 GHz, also next to the router.
The Mac says that the network has limited compatibility.
The 6 GHz network rejects the password that works on 5 GHz.

Likely causes

The Mac does not support 6 GHz. Apple lists Wi-Fi 6E or later for MacBook Pro from 2023 and MacBook Air with M3 or later. It also lists MacBook Neo, and iMac, Mac mini, Mac Studio and Mac Pro from 2023.
Wi-Fi 6E mode is off. Apple says that this setting turns off 6 GHz for one network only.
Security is not WPA3. Apple says that 6 GHz needs WPA3. A router can use WPA3 on 6 GHz and WPA2/WPA3 on the other bands.
Different names for each band. Apple says that the Mac then reports limited compatibility and can offer to join the 5 GHz network instead.
A 6 GHz-only network or a non-PSC channel. Ubiquiti says that 6 GHz-only networks can be hard to find. NETGEAR says that some clients do not find the router on a non-PSC channel.
6 GHz is off on the router, or not allowed in the region. Verizon says that Wi-Fi 6E is not on by default on its router. Apple says that Wi-Fi 6E is not available in mainland China.

How to check

Open Terminal. Show the channels that the Mac supports.
```
system_profiler SPAirPortDataType
```
Output If Supported Channels lists channels marked 6GHz, the Mac supports 6 GHz.
In the same output, find Current Network Information. The Channel line shows the band.
Choose Apple menu > System Settings > Wi-Fi. Click Details next to the network.
Look at Wi-Fi 6E mode. It must be Automatic.
Sign in to the router. Make sure that 6 GHz is on and that it uses WPA3.
Make sure that the 6 GHz band has the same name and password as the other bands.

How to fix it

Set Wi-Fi 6E mode to Automatic. Choose System Settings > Wi-Fi, then click Details next to the network.
Give all bands one name and one password on the router. Then forget the network on the Mac and join again.
If the router has a WPA3 setting for 2.4 and 5 GHz, turn it on. Google says that this helps 6 GHz devices move between bands.
Keep 2.4 and 5 GHz on the same network as 6 GHz. Do not make a 6 GHz-only network.
If you set the 6 GHz channel by hand, use a channel marked PSC.
Move closer to the router for a test.

Questions

Which Macs support Wi-Fi 7?

Apple lists Wi-Fi 7 for MacBook Pro with M5 Pro or M5 Max, and MacBook Air with M5. Their N1 chip also supports Multi-Link Operation.

Why does my Mac pick 5 GHz when 6 GHz is available?

macOS scores networks by channel use, client count and signal. A strong 5 GHz signal can score higher than a weak 6 GHz signal.

Can I make the Mac use only 6 GHz?

macOS has no band setting. Wi-Fi 6E mode can only turn 6 GHz off for one network.

Does eero steer Macs to 6 GHz?

On eero Pro 6E, Pro 7, Max 7 and PoE 7, Client steering can favour 6 GHz. But the company says that it cannot guarantee the band that a device picks.
