Changing the default wireless network access key is a priority task after installing the provider's equipment. Model Huawei HG8245H A fiber-optic terminal is a popular device often provided to subscribers for internet access. The default security settings listed on the manufacturer's label may be known or easily guessed by third parties, creating risks of unauthorized traffic use.
Changing your credentials doesn't require extensive networking knowledge, but it does require careful entry. Incorrectly configuring encryption settings or entering incorrect characters in the password field can result in loss of connection to all connected devices. In this guide, we'll detail the steps to ensure maximum security for your home network.
Before you begin, make sure your device (laptop, smartphone, or tablet) is connected to the router. This can be done either through Wi-Fi connection Using the current key or an Ethernet cable, which is a more secure option. A connection interruption while saving new settings may block access to the control interface until the equipment is rebooted.
Preparing to change security settings
The first step before logging into the admin panel is to check the physical accessibility of the device. Make sure the indicators on the device are on. ONT (Optical Network Terminal) lights are steady, not flashing red. It's best to use a wired connection for setup, as it eliminates the risk of connection interruption at a critical moment.
You will also need to know the default gateway address and login information. This information is usually found on a sticker located on the bottom of the device. Look for the lines IP Address, User And Password. In most cases for the model HG8245H The address 192.168.100.1 is used, but providers can change these parameters.
⚠️ Important: If you change settings via Wi-Fi, please be aware that changing the password or network name (SSID) will automatically disconnect your device. You will need to reconnect using the new data.
Write down the current settings or take a photo of the factory sticker before starting work. This will allow you to quickly restore access if unexpected errors occur during setup or you forget the new key you created. Backup configurations are a simple but effective precaution.
Login to the router's web management interface
To get started, open any modern web browser on the connected device. Enter the gateway IP address in the address bar. The standard address for Huawei equipment is often 192.168.100.1 or 192.168.1.1After entering the address, press Enter.
The system will request authorization. You will need to enter the administrator login and password. These pairs are often used. root / admin or telecomadmin / admintelecom, but the exact details depend on your provider. If the standard combinations don't work, please contact your company's technical support.
What to do if the page does not load?
If your browser says "Unable to connect," check that you've entered the IP address correctly. Also, make sure your computer's network adapter is set to obtain an IP address automatically (DHCP). Clearing your browser's cache or logging in through incognito mode can sometimes help.
After successful authorization, you'll be taken to the main device status page. The interface may differ depending on the firmware version, but the navigation logic remains the same. Look for the tabs with the following names: WLAN, Network or Wi-Fi Settings.
Find the wireless network settings section
Interface Huawei HG8245H Structured by horizontal or vertical menus. To change the password, we need to go to the section responsible for the wireless local network. Depending on the firmware version, this section may be called WLAN, Wi-Fi or Wireless.
Within this section there are often subsections such as Basic Configuration Settings (Basic settings) and WLAN Security Configuration (Security settings). We're specifically interested in the security configuration, where encryption types and access keys are set.
Please note that there are multiple profiles (SSIDs). The router can broadcast multiple networks simultaneously (e.g., Guest, 2.4GHz, 5GHz). You need to select the profile (SSID Name) whose password you plan to change. This is usually SSID1 or the network with the name indicated on the sticker.
If you don't see security settings, your user may not have sufficient privileges. Some providers hide advanced settings for regular users, leaving them accessible only to super administrators. In this case, changing the password is only possible through the provider's app or by calling support.
Setting a new password and encryption parameters
While in the security settings section (WLAN Security), find the field WPA PreSharedKey or WPA/WPA2 PassphraseThis is the field where you enter your new password. The old key will be hidden by asterisks or dots.
It is crucial to select the correct authentication mode. It is recommended to use WPA2-PSK or WPA/WPA2-PSKThe encryption algorithm must be set to AESUsing an outdated standard TKIP or regime WEP makes your network vulnerable to hacking in minutes.
Create a complex password of at least 12 characters. Use a combination of uppercase and lowercase letters, numbers, and special characters. Avoid obvious sequences, birthdays, or simple words that can be easily brute-forced.
⚠️ Note: Some older devices (such as previous-generation game consoles or smart plugs) may not support the WPA2-AES standard. If your device no longer detects the network after changing settings, try temporarily enabling WPA/WPA2 Mixed Mode.
After entering the new key in the confirmation field (if present), check that your keyboard layout and capitalization are correct. One extra letter or incorrect capitalization will prevent you from logging in. Save your changes by clicking the Apply or Save.
Saving configuration and reconnecting devices
After clicking the save button, the router will apply the new settings. This process takes 10 to 30 seconds. At this point, all wireless devices will lose their internet connection. This is normal system behavior.
Now you need to reconnect all your devices. On your smartphone or laptop, find your Wi-Fi name (SSID) in the list of available networks. Tap it and enter the new password. Make sure the device has received an IP address and has access to the global network.
☑️ Checklist after changing your password
If a device fails to connect, try "forgetting" the network in its settings and reconnecting. Sometimes the operating system caches old security settings and attempts to use them, which causes authentication errors.
It's also important to test the operation of wired clients, although changing the Wi-Fi password shouldn't affect LAN ports. However, a full router reboot after changing the settings will be helpful to stabilize all services.
Additional wireless network security measures
Changing your password is a basic, but not the only, step towards security. In the interface The HG8245H offers additional features worth considering. For example, MAC address filtering allows you to create a whitelist of devices allowed to connect.
It is recommended to disable this function. WPS (Wi-Fi Protected Setup) if you don't use it. This protocol is convenient for quick connections, but it has known vulnerabilities that allow attackers to recover the PIN code and gain access to the network.
| Parameter | Recommended value | Description |
|---|---|---|
| SSID Broadcast | Enable | Hiding the network only makes sense in specific cases; it is inconvenient for guests. |
| Encryption Mode | WPA2-PSK | The most secure encryption standard for home use. |
| Auth Mode | Open + Shared | Combined mode provides better compatibility with devices. |
| WPS Status | Disable (Off) | Disabling increases protection against PIN code guessing. |
It's also a good idea to regularly update your router's software. Providers release updates that patch security holes. You can check for a new version in the section System Tools -> Update.
Solution and access restoration
If you can't access your router settings after changing your password, your browser may be using old cached data. Try clearing the cache or using incognito mode. Also, make sure your computer is on the same subnet as the router.
If you've forgotten your new Wi-Fi password and can't connect from any device, you can still reset your device. There's a reset hole on the back of your device. ResetPress it with a paper clip and hold for 10-15 seconds until the indicators blink.
⚠️ Warning: A hard reset will return your router to factory settings. This means your internet will stop working until you re-enter the authentication information (PPPoE, VLAN, etc.) provided by your ISP. Only do this if you are confident in your abilities or have this information readily available.
A common issue is IP address conflicts or DHCP server malfunction after changing settings. Restarting the router and client (computer/phone) resolves 90% of these issues. If the problem persists, check to see if parental controls or access time restrictions are enabled on the router.
Please note that the interface and terminology may differ slightly depending on the firmware version of your device. HG8245HIf you can't find a specific menu item, check the documentation on the manufacturer's official website or ask your company's technical representative for details.
Is it possible to change the password via the mobile app?
Yes, many providers develop their own apps for managing home networks (e.g., My Rostelecom, Dom.ru, etc.). If your router is linked to your personal account, you can change the password in the Wi-Fi management section without logging into the 192.168.100.1 web interface.
What is the maximum length of a Wi-Fi password?
The WPA2-PSK standard allows keys from 8 to 63 characters long. Passwords shorter than 8 characters are not permitted by the security system. The optimal length for a balance between security and ease of entry is 12-16 characters.
What should I do if I forgot my router admin password?
If you changed your web interface password (username: admin) and forgot it, you can't recover it without a factory reset. You'll have to perform a hard reset using the button on the device, which will reset all settings, including internet options.
Does changing your password affect your internet speed?
Changing your password itself doesn't affect speed. However, if you've switched from WEP to WPA2-AES, your speed may actually increase due to more efficient bandwidth usage and the absence of third-party users "stealing" your traffic.
