To force your iPhone hotspot to 2.4GHz, turn on the Maximize Compatibility toggle in Settings > Personal Hotspot. This is the only documented way to make an iPhone hotspot 2.4GHz, and it works on iPhone 12 or later; on iPhone 11 and earlier, the hotspot is already 2.4GHz only.
Step 1: Enable Personal Hotspot on iPhone
- Open Settings.
- Tap Personal Hotspot. If the menu is not visible, go to Settings > Cellular > Personal Hotspot instead. If Personal Hotspot is not visible, Apple's support wording says it may be reached through Settings > Cellular > Personal Hotspot.
- Toggle the switch to enable Personal Hotspot.
Once enabled, your iPhone will broadcast a Wi‑Fi network that other devices can join. If you need to know how to get personal hotspot on your iPhone, this is the exact path.
Step 2: Force the hotspot to 2.4GHz with Maximize Compatibility
- Stay in Settings > Personal Hotspot. AT&T's device support page for iPhone 15 says the same menu path and switch label: Settings > Personal Hotspot > Maximize Compatibility.
- Turn on Maximize Compatibility.
This setting is available on iPhone 12 or later. The documented way to make an iPhone hotspot use 2.4 GHz is Settings > Personal Hotspot > Maximize Compatibility, and it applies to iPhone 12 or later. When enabled, Apple’s documentation confirms it turns off the 5 GHz and, if applicable, 6 GHz bands, leaving only the 2.4 GHz band with WPA2 Personal security. When Maximize Compatibility is on, Apple says the hotspot uses WPA2 Personal security. On iPhone 11 and earlier, the hotspot is already 2.4 GHz only, so no toggle is needed. iPhone 11 and earlier hotspot is documented as 2.4 GHz only. Understanding how does hotspot work here is simple: compatibility mode forces the iPhone to broadcast on the older, longer-range band that older devices can see.
Step 3: Connect a device to your iPhone hotspot
- On the device you want to connect, open its Wi‑Fi settings.
- Find the iPhone’s network name, which is shown under Settings > Personal Hotspot.
- Enter the hotspot password displayed on the same iPhone screen.
Turning on Maximize Compatibility improves the chance that older devices, such as a legacy laptop, a 2.4 GHz-only tablet, or a smart home gadget, can find and connect to the hotspot.
Troubleshooting tips
- Older device can’t see the hotspot: Turn on Maximize Compatibility in Settings > Personal Hotspot. This is the most common fix.
- Hotspot menu is missing: Check Settings > Cellular first; the Personal Hotspot option may be nested there depending on your carrier settings. If the hotspot menu does not appear directly in Settings, check Settings > Cellular first.
- Performance or security tradeoffs: Apple documents that compatibility mode reduces performance because it disables higher bands, and it changes security to WPA2 Personal (instead of newer standards). Apple documents a tradeoff: enabling compatibility mode may reduce performance because it disables higher bands. Apple's documentation says compatibility mode can reduce security from newer modes to WPA2 Personal and can reduce performance. Use it only when you need to connect a 2.4 GHz-only device.
Frequently Asked Questions
Does every iPhone support 2.4 GHz hotspot mode?
Yes, but differently. iPhone 11 and earlier are documented as 2.4 GHz only. iPhone 12 or later can switch to 2.4 GHz by turning on Maximize Compatibility in Settings > Personal Hotspot. Does every iPhone support 2.4 GHz hotspot mode? Yes, but differently: iPhone 11 and earlier are documented as 2.4 GHz only, while iPhone 12 or later can switch to 2.4 GHz with Maximize Compatibility.
What exactly does Maximize Compatibility do?
What exactly does Maximize Compatibility do? Apple says it turns off 5 GHz and, if applicable, 6 GHz, leaving 2.4 GHz and WPA2 Personal. This makes the hotspot visible to devices that cannot see 5 GHz or 6 GHz networks.
Can multiple devices connect to the iPhone hotspot at the same time?
Yes. The iPhone supports up to five simultaneous Wi‑Fi connections, regardless of whether Maximize Compatibility is on or off.
Will turning on Maximize Compatibility slow down my hotspot?
Yes, because it disables the faster 5 GHz and 6 GHz bands. Apple documents that compatibility mode may reduce performance.
Is it safe to use Maximize Compatibility?
Yes, but security is reduced from newer standards to WPA2 Personal. This is still considered secure for most personal hotspot use cases, though it is not as strong as WPA3.
