What Is Wi‑Fi 6E and Why Does It Cause Mac Problems?
Wi‑Fi 6E adds a third frequency band – 6 GHz – alongside 2.4 GHz and 5 GHz. This band is wider, less crowded, and potentially faster. However, it is also newer, and both router firmware and macOS have had teething problems. mac wifi 6e issues include:
- Mac connects to 5 GHz instead of 6 GHz.
- Frequent disconnects when roaming between bands.
- Slower speeds on 6 GHz than expected.
- Mac fails to see the 6 GHz network at all.
These problems are especially common on M2, M3, and M4 MacBooks from 2023‑2026. If your mac keeps disconnecting from wifi and you have a Wi‑Fi 6E router, this guide is for you.
For general Wi‑Fi troubleshooting, see our pillar post. For signal strength basics, see Mac Wi‑Fi signal strength guide (cluster post #1).
Which Macs Support Wi‑Fi 6E?
Not all Macs have Wi‑Fi 6E hardware. The following models support it:
| Mac Model | Year | Wi‑Fi 6E Support |
|---|---|---|
| MacBook Pro 14″ and 16″ | 2023 (M2 Pro/Max) | Yes |
| MacBook Pro 14″ and 16″ | 2024 (M3 Pro/Max) | Yes |
| MacBook Pro 14″ and 16″ | 2025‑2026 (M4, M5) | Yes |
| MacBook Air | 2024 (M3) and later | Yes |
| Mac mini | 2023 (M2) and later | Yes |
| Mac Studio | 2023 (M2) and later | Yes |
| iMac | 2024 (M3) and later | Yes |
| Older Macs (Intel, M1) | 2022 and earlier | No – 5 GHz only |
If your Mac is not listed, Wi‑Fi 6E issues do not apply. However, your router may still broadcast a 6 GHz network that your Mac ignores – that is normal.
For checking your Mac’s model, see our Mac sleep mode optimizer (internal link placeholder #17 from pillar) – not directly related but the system info is the same.
Common Wi‑Fi 6E Issues on Mac (Disconnects, Slow Roaming, No 6GHz)
Here are the most frequent complaints from Mac users with Wi‑Fi 6E routers:
Issue 1: Mac refuses to connect to 6 GHz
Your router broadcasts 6 GHz, but your Mac stays on 5 GHz. Check the Wi‑Fi menu (Option‑click) – it shows the band. If it says “5 GHz,” your Mac is not using 6 GHz.
Issue 2: Frequent disconnects when moving around
As you walk away from the router, your Mac tries to switch from 6 GHz to 5 GHz. During the switch, the connection drops for 5‑10 seconds. This is poor roaming implementation.
Issue 3: 6 GHz speed is slower than 5 GHz
6 GHz has shorter range. If you are far from the router, 5 GHz may actually be faster. Your Mac should automatically choose the best band, but sometimes it does not.
Issue 4: Battery drain on MacBooks
6 GHz scanning consumes more power. Some users report 10‑15% shorter battery life with Wi‑Fi 6E enabled.

Fix 1: Disable 6GHz Mode Temporarily
If you are experiencing constant disconnects, the quickest fix is to disable 6 GHz on your Mac. This forces it to use 5 GHz, which is more stable (though less future‑proof).
Steps to disable 6 GHz for a specific network:
- System Settings > Wi‑Fi.
- Click the Details (ⓘ) button next to your network.
- Look for 6 GHz Mode. Set it to Off (or Disabled).
- Reconnect.
If you do not see this option, your macOS version may be older. Update to the latest version (see how to update macOS safely placeholder #7). Alternatively, your router may not advertise 6 GHz correctly.
After disabling, test for a day. If disconnects stop, the issue is definitely related to 6 GHz. You can later re‑enable and try other fixes.
Fix 2: Use a Single SSID for All Bands
Many routers create separate network names (SSIDs) for 2.4 GHz, 5 GHz, and 6 GHz. For example: MyWiFi, MyWiFi-5G, MyWiFi-6G. This forces you to manually choose a band, which defeats roaming.
Solution: Change your router settings to use one SSID for all bands (often called “band steering” or “smart connect”). Then your Mac automatically picks the best band at any moment.
How to enable band steering:
- Log into your router (192.168.1.1 or similar).
- Look for Wi‑Fi settings. Find an option like “Band Steering,” “Smart Connect,” or “Same SSID for all bands.”
- Enable it. Save and reboot the router.
- On your Mac, forget the network and rejoin (see pillar post Fix 2 for details).
After this, your Mac should roam between 2.4, 5, and 6 GHz seamlessly.
For router configuration help, see our router setup guide for Mac users (internal link placeholder #9 from pillar).
Fix 3: Adjust 6GHz Channel Width (80 vs 160 MHz)
6 GHz allows very wide channels (up to 160 MHz or even 320 MHz on Wi‑Fi 7). Wider channels offer higher speeds but shorter range and more interference. Some Macs struggle with 160 MHz channels.
What to try:
Log into your router. Find 6 GHz Channel Width. Change from 160 MHz to 80 MHz. Save and reboot.
After the change, reconnect your Mac. Test stability. If disconnects stop, your Mac does not like the wider channel. You can keep it at 80 MHz – the speed difference is minor for most uses.
For iPhone and iPad also affected by 6 GHz, see our iPhone Wi‑Fi disconnecting fix (cluster post #2) and iPad network issues (cluster post #3).
Fix 4: Update macOS and Router Firmware
Both Apple and router manufacturers have released updates that improve Wi‑Fi 6E stability.
On your Mac:
- System Settings > General > Software Update. Install any available updates. macOS 26.4.1 (April 2026) included several 6 GHz roaming improvements.
On your router:
- Log into admin panel. Look for Firmware Update. Install the latest version. Many routers (Netgear Orbi, Eero Pro 6E, Asus GT‑AXE11000) have released patches for Mac compatibility.
After updating both, restart your Mac and router. Test again.
For update instructions, see our how to update macOS safely guide (internal link placeholder #7 from pillar).
Fix 5: Forget and Rejoin the Network After Changes
After changing any router settings (band steering, channel width, firmware), your Mac may still remember the old configuration. Forcing it to re‑authenticate helps.
Steps:
- System Settings > Wi‑Fi > Details (ⓘ) next to your network.
- Click Forget This Network.
- Restart your Mac.
- Reconnect by selecting the network and entering the password.
This ensures your Mac picks up all the new router settings.

When to Disable Wi‑Fi 6E Permanently
Despite all fixes, some Macs simply have poor 6 GHz implementation. If you still experience disconnects, roaming problems, or battery drain, consider disabling 6 GHz permanently on your Mac for that network. You can also disable it on the router (turn off 6 GHz radio) – but that affects all devices.
To disable on your Mac (per network):
Follow Fix 1 – set 6 GHz Mode to Off. Your Mac will use 5 GHz only.
To disable on your router:
Log into router, find 6 GHz settings, and disable the band. Your Mac will then connect via 5 GHz.
For most users, the speed difference between 5 GHz and 6 GHz is negligible for everyday tasks (browsing, streaming, email). Stability is far more important. You can re‑enable 6 GHz in a year after more mature firmware updates.

Frequently Asked Questions
Q: My Mac supports Wi‑Fi 6E, but I never see “6 GHz” in the Wi‑Fi menu. Why?
Your router may not be broadcasting 6 GHz, or you are too far away. 6 GHz has very short range – often only one room. Stand next to the router and check again.
Q: Does Wi‑Fi 6E drain MacBook battery faster?
Yes, by 10‑15% on average. The 6 GHz radio consumes more power. If battery life is critical, disable 6 GHz (Fix 1).
Q: I have an Intel Mac. Can I use Wi‑Fi 6E?
No. Intel Macs do not have the necessary hardware. Only Apple Silicon Macs from 2023 onward support Wi‑Fi 6E.
Q: My Mac connects to 6 GHz but then drops after a few minutes.
This is a known roaming bug. Update to macOS 26.4.1 or later. Also try Fix 2 (single SSID) and Fix 3 (80 MHz channel width).
Q: Will Wi‑Fi 7 solve these issues?
Wi‑Fi 7 (802.11be) is backwards compatible but also introduces new complexities. Early adopters may face similar teething problems. For now, 5 GHz remains the most stable choice.
Q: I turned off 6 GHz, but my Mac still disconnects. What now?
The problem is not Wi‑Fi 6E specific. Return to the pillar post and work through AWDL, Bluetooth, and sleep settings.
