Changing the name of the wireless network is the first thing that comes to mind when initially setting up a router, but many users live for years with factory designations like "TP-LINK_2G_45A1" or "Keenetic-5G". Changing SSID (Service Set Identifier) not only makes your network recognizable among neighboring signals but is also a basic element of digital hygiene. Standard names often contain information about the device model, which can make it easier for attackers looking for vulnerabilities in specific firmware.
The renaming process is technically simple, but requires care, as saving the changes will cause all connected devices to lose connection to the router. You'll have to re-enter the password on smartphones, laptops, and smart TVs, as this will appear to them as a completely new access point. In this article, we'll detail the steps for various interfaces and answer frequently asked questions.
What is an SSID and why should I change it?
SSID — is a unique identifier assigned to a wireless local area network that allows devices to find and connect to the desired internet source. Essentially, it's the name you see in the list of available connections on your phone or computer. Factory settings are usually generated automatically based on the MAC address or router model, which isn't always user-friendly, especially in multi-family buildings with high network density.
Renaming your network serves several practical purposes. First, it helps clearly identify your signal if you or your neighbors have additional repeaters or mesh systems installed. Second, a unique name doesn't reveal your equipment model, concealing potential attack vectors specific to certain brands. Third, it's simply aesthetically pleasing and convenient to broadcast "Apartment_42_WiFi" instead of a string of random characters.
- 📡 Identification: Allows you to instantly distinguish your network from dozens of neighboring signals in an apartment building.
- 🔒 Safety: Hides the router model, making it more difficult to find exploits for specific firmware vulnerabilities.
- 🏠 Organization: Helps structure your network if you use guest access or separate channels for your smart home.
⚠️ Attention: When changing the SSID, avoid using personal information such as your last name, apartment number, or exact address. This could be useful for social engineering or burglary.
Preparing for setup: accessing the admin panel
Before making any configuration changes, you need to access your router's web interface. To do this, the device you plan to use to manage the settings must be connected to the router. A wired connection via Ethernet- a cable to eliminate the risk of connection loss while saving parameters, although login is also possible via Wi-Fi.
Open any browser and enter the gateway IP address in the address bar. Most often, this is 192.168.0.1 or 192.168.1.1, however, some manufacturers, for example Asus or Keenetic, can use domain names like router.asus.comThe exact address, as well as the default login and password, are usually indicated on a sticker located on the bottom or back of the device.
After entering your login credentials, the control panel will open. Interfaces may vary from manufacturer to manufacturer, but the logic remains the same. If you've previously changed the administrator password and forgot it, you'll need to perform a factory reset, which will require you to configure your internet connection.

Instructions for changing the network name on popular routers
Firmware interfaces vary greatly, so let's look at the algorithms for the most common brands. On devices TP-Link With the new green interface you need to go to the menu Basic → WirelessIn the field Wireless Network Name A new name is entered. Please note that if the router is dual-band, the names for 2.4 GHz and 5 GHz can be set separately or combined using the function Smart Connect.
In routers Asus Navigation is carried out through the left menu. Select the item Wireless (Wireless Network) At the top of the page there is a field SSIDHere you can also set up a guest network, giving it a separate name, which is useful for temporary visitors. After entering the information, be sure to click the button Apply (Apply).
Devices Keenetic (formerly Zyxel) have a modular structure. Go to the section My Networks and Wi-Fi → Home networkIn the Wi-Fi settings block you will see a field Network name (SSID)The unique feature of these routers is the ability to flexibly configure security and client isolation directly in the same window, without having to navigate through extensive menus.
| Router brand | Menu section | Field name | Save button |
|---|---|---|---|
| TP-Link | Basic / Wireless | Wireless Network Name | Save |
| Asus | Wireless / General | SSID | Apply |
| Keenetic | My Networks and Wi-Fi | Network name (SSID) | Apply |
| D-Link | Wi-Fi / Basic Settings | SSID | Apply |
Naming Rules: What You Can and Can't Use
When choosing a name, consider not only creativity but also technical compatibility. Wi-Fi standards support encoding. ASCII, which allows the use of Latin letters, numbers, and some special characters. Using Cyrillic (Russian letters) is highly discouraged, as many older devices, IoT gadgets (light bulbs, sockets), and operating systems may display such names incorrectly or not recognize the network at all.
The name length also has limitations. Typically, 1 to 32 characters are allowed. Exceeding this limit will result in the name being truncated or an error when saving. Also, spaces at the beginning and end of a line should be avoided, although they are allowed within the text. Special characters such as /, \, " may be reserved by the system and cause a failure in the operation of the wireless module drivers.
From a security standpoint, avoid names that indicate a lack of security, such as "Free_WiFi" or "No_Password," even if a password is set. This could attract the attention of nosy neighbors or hackers trying to test your network's strength. A neutral name is the best defense against unwanted attention.
Impact of changing SSID on connected devices
Once you click the save button in the router interface, the wireless module will restart with the new settings. For all clients, this is equivalent to the old network disappearing and a new one with the same name appearing. Devices that were previously connected will not be able to reconnect automatically, even if the password remains the same, since they identify the network by its name. SSID.
You'll need to take each smartphone, tablet, laptop, Smart TV, and smart speaker and reconnect. From the list of available networks, select the new name and enter the password. On some devices, such as iOS or Android, you may need to forget the old network in your Wi-Fi settings so that the system stops trying to connect to the now non-existent identifier.
Particular attention should be paid to the devices Internet of Things (IoT). Cameras, leak detectors, and smart switches often lack a password entry screen. After changing the network name, they will need to be reset to factory settings and reconfigured through the app, which can take considerable time if you have many such devices.
⚠️ Attention: If you have a Smart Home system configured, make sure the hub or gateway connects to the network with the new name, otherwise all automation scenarios will stop working until the central controller is reconfigured.
Hiding the SSID: Is It Worth Making Your Network Invisible?
In wireless network settings, you can often find the option Hide SSID (Hide SSID). When this feature is enabled, the router stops broadcasting the network name, and it disappears from the list of available connections on phones and laptops. To connect, the user must manually enter the network name and security type.
Many consider this a panacea for hacking, but security experts are skeptical. The hidden network doesn't disappear completely: it continues to send service packets, which are easily detected by specialized scanners. Moreover, your devices, trying to find the "hidden" network, begin constantly broadcasting requests with its name, making you more visible to tracking.
Using a hidden SSID often leads to problems connecting new devices and reduced network speed due to unnecessary service traffic. It's much more effective to use a secure encryption protocol. WPA3 or WPA2-AES and a complex password rather than relying on "security through obscurity."
Technical details of network hiding
When SSID hiding is enabled, the router stops sending beacon frames with the network name. However, when a client device attempts to connect, it sends a probe request containing the network name in cleartext. Specialized software, such as Kismet or Airodump-ng, instantly intercepts these packets and reveals the hidden name.
Common problems and solutions
After renaming a network, users may encounter devices that don't see the router or are unable to connect. A common cause is caching of old DNS or DHCP data on the client device. In this case, a simple smartphone reboot or reset of network settings can resolve the issue. The problem could also be related to the channel: if you accidentally changed not only the name but also the region or channel to one not supported in your country, devices may lose connection.
If the name isn't saved or the input field is inactive, check whether guest access is enabled as your primary network or whether the settings are blocked by your ISP (this is rare, but can happen when using operator ONT terminals). In some cases, clearing the browser cache or logging into the control panel in incognito mode can help.
Button locations and menu item names may vary. If you don't see the options described, check the official documentation for your specific model and software version on the manufacturer's website.
Is it possible to use Russian letters in a Wi-Fi name?
Technically, the standard allows for extended encoding, but in practice, this causes a host of problems. Older devices, game consoles, and smart home appliances often display gibberish instead of letters or simply ignore the network. It's better to use transliterated text or English equivalents.
Will my internet password be reset after changing the SSID?
No, the ISP password (PPPoE, L2TP, etc.) is stored in a different part of the configuration and is independent of the wireless network name. However, to connect to the Wi-Fi network itself, you'll have to re-enter the password on all devices unless you use WPS (which, however, is best disabled).
How do I get everything back if I forgot my new password?
If you've lost access to the network, the only solution is to connect your computer to the router with a cable and access the settings to view or change the password. If you've also forgotten the password for the admin panel, the only solution is to perform a full reset using the button on the router case, which will restore the factory username and password listed on the sticker.
Does the length of the SSID name affect internet speed?
Theoretically, a longer name takes up more space in the frame header, but this difference is so microscopic (a fraction of a percent) that in real life it has no impact on page loading speed or video viewing. Choose a name based on convenience, not length.
