Smartphone and tablet users often encounter a situation where the familiar wireless network icon changes its appearance. Instead of the standard arcs indicating signal strength, a small star symbol appears on the icon. This phenomenon is puzzling, as standard manuals rarely describe such visual indicators. Typically, this change indicates that the device is attempting to connect to a saved network but is encountering certain limitations or errors.
In most cases, the appearance of an asterisk means that your gadget cannot obtain an IP address The router is disconnected or the internet is unavailable despite successfully connecting to the access point. This can be caused by software glitches in the smartphone's operating system or incorrect router settings. Understanding the exact cause allows you to quickly restore a stable connection without the need for complex hardware diagnostics.
This article will examine in detail all possible scenarios for this indicator to appear on various operating systems. We will examine the differences between devices based on Android And iOS, and also pay attention to the router's settings. It's important not to ignore this signal, as it often precedes a complete loss of connection or indicates connection security issues.
What does the asterisk mean on Android and iOS?
The interpretation of icons in the status bar depends on the operating system and shell version installed by the manufacturer. On devices Samsung, Xiaomi or Huawei An asterisk often appears next to the network name in the list of available connections. This means that the network is chosen one or priority, but the connection to it is currently inactive. If the star is illuminated directly on the icon in the top row, this most often indicates a lack of access to the global network.
In the ecosystem Apple The situation is a little different. In iOS, an asterisk next to a Wi-Fi network's name in Settings indicates that the feature is enabled for that network. Private Wi-Fi AddressThis is a security feature that generates a random MAC address for a device to hide its real identity from network owners. However, if the asterisk is blinking or red, this is a clear sign that authorization is not possible.
⚠️ Note: On some smartphone models, the asterisk may indicate that the "Wi-Fi Assist" or similar feature is enabled, which switches traffic to the mobile network when the router signal is weak.
Differences in status display can be confusing, so it's important to check your specific device model. Users often confuse the favorite network indicator with an error indicator. To accurately determine the status, simply tap the icon and check the system's pop-up message.
The main reasons for the indicator's appearance
There are several fundamental reasons why the system displays this symbol. The first and most common is IP address conflictThe router may not assign a new address to the device if the DHCP address pool is exhausted or if the static address manually assigned to the phone is already taken by another device on the network.
The second reason is often access restrictionsIf you're in a public place, office, or visiting friends, your network administrator may have set up a MAC address filter. In this case, your phone sees the network and tries to connect, but the router blocks data transmission, and the system marks the connection with an asterisk or exclamation point.
- 📶 Weak signal: The reception level is insufficient for a stable handshake with the router, data packets are lost.
- ⚙️ DHCP Failure: The automatic address distribution service on the router is frozen or not working correctly.
- 🔒 Password error: The saved security keys do not match the current access point settings.
It's also worth considering software errors in the operating system itself. After a firmware update, the network module settings may be reset or corrupted. In this case, the phone "remembers" the network, but cannot initiate a connection correctly, displaying a warning symbol.
Impact of energy saving
Power saving modes on Android often limit background Wi-Fi activity. The system may forcefully disconnect the connection or not prioritize IP address requests, which causes the asterisk to appear. Try disabling power saving mode to test.
Router issues and DHCP settings
If the problem occurs across all devices in the home, the source of the problem should be looked for in the router settings. An asterisk on the connection often indicates a DHCP table overflow. By default, the router assigns addresses in a specific range, for example, from 192.168.1.2 to 192.168.1.100. If many smart devices (lamps, outlets, phones) are connected to the network simultaneously, there may not be enough available addresses.
To resolve this issue, you need to log into your router's control panel. This is usually done through a browser at 192.168.0.1 or 192.168.1.1. In the section LAN or DHCP Server The address pool needs to be expanded. It's also recommended to increase the lease time so that devices retain their IP addresses longer and don't constantly request new ones.
Another important parameter is - wireless communication channelIf neighboring routers are operating on the same channel, interference occurs. The device sees the network but can't break through the noise to establish a connection. Automatic channel selection doesn't always work correctly, so manual configuration is often required.
⚠️ Note: Changing DHCP settings or Wi-Fi channels requires a router reboot. During this time, the internet will be unavailable on all devices.
Don't forget about your router's firmware either. Outdated software may contain bugs that can cause the DHCP server to malfunction. Manufacturers regularly release updates to fix these stability issues.
Smartphone operating system failures
If the router is working properly, but the asterisk appears only on one device, the problem lies in the smartphone's software. The operating system may have "remembered" the network configuration. The network settings cache stores old parameters that conflict with current security requirements or encryption protocols.
Often the problem can be solved by a simple but effective procedure - forget the networkThis action deletes all saved connection data, including passwords, static IP addresses, and proxy settings. After this, the phone will treat the network as a new one and request connection parameters from scratch.
In more complex cases, resetting all network settings is necessary. This is a more drastic method, affecting not only Wi-Fi but also Bluetooth and mobile network settings. However, it is guaranteed to resolve software conflicts caused by system updates or installing apps with deep access rights.
- 📱 Cache overflow: The Wi-Fi service's temporary files are taking up too much space or are corrupted.
- 🛡️ Antivirus software: Third-party security applications may block network requests because they consider them suspicious.
- 🔄 Version conflict: Incompatibility of security protocols (WPA2/WPA3) between the phone and the router.
Pay special attention to the date and time on your device. If the time is out of sync, security certificates fail verification, and the connection is marked as unreliable or limited. Synchronizing the time over the internet often resolves the issue immediately.

Comparison of connection statuses
To better understand the network status, it's helpful to understand the differences between the various indicators. The asterisk isn't the only symbol that may appear. The system uses a whole range of symbols to communicate with the user about the technical status of the communication channel.
| Indicator | Meaning | Action |
|---|---|---|
| Asterisk (*) | Limited access or selected network | Check IP settings |
| Exclamation mark (!) | No internet access | Check the router |
| Up/Down Arrows | Data is being transferred | Norm |
| Question mark (?) | Authorization required (Captive Portal) | Open browser |
Understanding these differences helps you diagnose the problem faster. For example, if an exclamation point is displayed, the problem is almost certainly with your ISP or router. If a question mark is displayed, you're connected to a public network and need to enter your phone number or accept the terms of service on the start page.
It is important to note that on different versions Android Graphics may vary depending on the operating system (MIUI, OneUI, EMUI). Therefore, it's always worth checking the official user manual for your specific model if standard methods don't help.
Step-by-step instructions for troubleshooting the error
To restore a normal connection, we recommend proceeding sequentially, moving from simple to complex steps. Don't try resetting your entire phone to factory settings at the first sign of trouble. Start by rebooting your device and checking basic settings.
The first step should always be reboot the routerUnplug it for 10-15 seconds, then plug it back in and wait for it to fully boot up. This clears the device's RAM and restarts all services. If the asterisk disappears, the issue was a temporary glitch.
If rebooting doesn't help, follow these steps on your smartphone:
- Open Wi-Fi settings.
- Find the problem network.
- Select "Remove network" or "Forget".
- Turn the Wi-Fi module off and on.
- Try connecting again by entering your password.
If the issue persists, try setting a static IP address. In the advanced Wi-Fi network settings, change the IP settings from "DHCP" to "Static." In the IP address field, enter the value corresponding to your subnet (e.g. 192.168.1.150), gateway - router address, DNS can be specified public from Google (8.8.8.8).
⚠️ Important: When registering a static IP, make sure that the selected address is not occupied by another device on the network, otherwise an address conflict will occur.
The final step is to reset your phone's network settings. Keep in mind that this will delete all saved passwords for Wi-Fi and Bluetooth devices. After the reset, the phone will reboot, and you'll need to reconnect all peripherals.
Hidden Android Settings
In some cases, turning on airplane mode for 1 minute can help. This forcibly disables all radio modules and resets their state, which is more effective than simply turning off Wi-Fi.
Frequently Asked Questions (FAQ)
Why did the star appear after updating my phone?
Operating system updates often change network algorithms or reset configuration files. Old settings may conflict with new security protocols. Solution: forget the network and reconnect.
Does the asterisk mean I've been hacked?
No, in 99% of cases, this is a technical indicator of a connection error or limited access. However, if you're connected to an unknown open network, the risk of data interception does exist.
Can an antivirus cause an asterisk to appear?
Yes, some aggressive antivirus programs may block network traffic if they deem the network unsafe. Try temporarily disabling the protection to test.
What should I do if the star is only visible on one site?
If your Wi-Fi is working but a specific website won't load, the problem isn't with the icon, but with DNS or a blocked resource. Try changing the DNS servers in your Wi-Fi settings to 1.1.1.1 or 8.8.8.8.
How do I know if my device is blocked by my router?
Go to the "Client List" or "Wireless Status" section of your router's admin panel. If your device isn't listed there, even though it's trying to connect, it means there's a MAC address filter enabled.
