You turned on modem mode on iPhone, but your computer stubbornly refuses to connect to the access point you created? This problem is familiar to many, especially if everything worked fine before. The reasons may lie in the settings. iOS, as well as in the configuration Windows/macOS, and sometimes even the mobile operator is to blame. In this article, we'll look into all possible failure scenarios, including rare cases where a hardware failure of the Wi-Fi module in the smartphone is to blame.
It is important to understand: modem mode on iPhone works through a combination Wi-Fi, Bluetooth or USBWe will focus specifically on Wi-Fi-connection, as it is the most convenient for most users. If your PC "sees" the network from iPhone, but it doesn't connect—or doesn't even show up in the list—the solutions will vary. We'll start with basic checks and move on to a more in-depth diagnosis.
1. Basic checks: what to do first
Before digging deep into the settings, make sure the problem isn't solved by simple actions. Experience shows that in 60% of cases, a banal failure or forgotten change.
- 🔄 Restart both devices. Turn it off. iPhone for 30 seconds, then turn off the computer. This will clear temporary errors in the modules.
Wi-Fi. - 📶 Check your mobile network signal. Modem mode requires a stable 3G/4G/5GIf on iPhone just 1-2 network divisions, the access point may not start.

For macOS:
- 🍎 Remove the network from memoryGo to .
System Preferences → Network → Wi-Fi → Advanced, find the network from iPhone and delete it by clicking "–". - 🔄 Reset NVRAM. Turn it off. Mac, then turn it on while holding down the keys
Option + Command + P + Rfor 20 seconds. - 📡 Check your DNS settings. In the same menu
Advanced → DNSAdd Google's public DNS:8.8.8.8And8.8.4.4.
If the computer sees the network, but when connecting it gives an error "Unable to connect" or "Limited", try specifying it manually IP address:
- IN Windows:
Control Panel → Network and Internet → Network and Sharing Center → Change adapter settings→ right click onWi-Fi→Properties→Internet Protocol version 4 (TCP/IPv4)→ specify192.168.2.2(mask255.255.255.0, gateway192.168.2.1). - IN macOS: in the network settings, select
Manualconfiguration and enter the same parameters.
4. Conflicts with other devices and networks
Modem mode on iPhone may conflict with others Wi-Fi-networks or devices. For example, if there is a router nearby on the same channel, or iPhone another device is already connected (even if it is inactive).
What to check:
- 📡 Change Wi-Fi Channel on iPhone. By default iOS Selects a channel automatically, but it may be overloaded. To change it manually:
How to change the Wi-Fi channel on an iPhone using Personal Hotspot?
Unfortunately, the default iOS settings don't allow you to manually select a channel for tethering. However, you can try to bypass this limitation:
1. Disable tethering.
2. Connect your iPhone to another Wi-Fi network (such as your home router).
3. Turn Personal Hotspot back on – sometimes this forces iOS to select a different channel.
- 📱 Disconnect other devicesModem mode on iPhone supports up to 5 connections, but sometimes even one "sleeping" device (for example, a tablet) can cause failures.
