Modern smartphones like the Xiaomi Redmi 9 are often used not only for calls but also as multimedia centers for watching high-resolution movies. However, the device’s internal memory is often not enough to store huge libraries of video and music. The solution is to connect to a NAS network storage or computer via the NFS (Network File System) protocol, which allows you to access files on a remote drive as if they were in your phone’s memory, without having to download them beforehand.
The setup process may seem daunting for a beginner, but it really only requires attention to detail and the right network settings input.Redmi 9 owners are lucky with the MIUI shell, which has quite flexible security settings, although it requires manual activation of some features.We will take all the nuances, from preparing the router to choosing the right client application so that you can enjoy content without delay.
It is worth noting that the stability of the connection depends on the quality of your Wi-Fi network. 4K-Movies, it is recommended to use a frequency of 5 GHz. NFS It is often faster and more stable on a local network than on a local network. SMB, Especially on mobile devices, as it less loads the processor when encoding data.
Preparation of network infrastructure and router
Before picking up a smartphone, you need to make sure your home network is ready to work with the protocol. NFS. Most modern routers support connection USB-disks or have a built-in file system that can be shared over the network. You need to log into the router's settings through the browser by entering IP-Gateway address, usually 192.168.0.1 or 192.168.1.1.
In the router interface, find the section responsible for USB-applications or file sharing. You need to activate the server. NFS. It is important to configure access rights correctly: for home use, it is usually enough to open access to all devices on the local network or create a specific user with read and write rights. IP-address of your router or NAS-server, as it will be necessary to connect.
⚠️ Warning: Make sure that your files and your Xiaomi Redmi 9 are on the same subnet.If you have guest Wi-Fi networks set up, they can be isolated from the main network where the storage is located.
Once you activate the service, check it from your computer, try to open the network folder. If everything works on your PC, then the server part is configured correctly, and you can move on to the setting of the smartphone itself. USB-The router port also plays a role: if the drive doesn’t rotate, it may lack power.
MIUI built-in tools for network access
Shell MIUI, The one that's installed on Redmi 9 has its own file manager that can work with network resources, and it's the easiest way to do that without having to install any additional software. Open Explorer and go to Network or click on the add icon. The system will automatically try to find the available NFS-servers.
If the automatic search didn't give results, select manual server addition. IP-The address of your storage that you recorded during the preparation phase. In the connection type field, be sure to select NFS, As the default may be SMB. The port usually remains standard at 2049, but if you have changed your server settings, specify the current value.
Once you enter, click OK or Connect. If the settings are correct, you will see the contents of the remote folder. The built-in explorer is convenient for quick access to documents and photos, but it may be limited to play heavy video, and it's great for checking the connection before installing dedicated players.
💡
Use static. IP-address NAS router in settings DHCP. This will prevent situations where the address will change after the hardware reboot and the connection in the phone will stop working.
Use of Third-Party File Managers
For more advanced networking, Xiaomi Redmi 9 is better equipped with a dedicated file manager, such as CX File Explorer or ES Explorer (modified version), which provides more flexible connection settings and better cache data, which makes it easier to navigate through large file lists.
Let's take a look at a popular manager, and then go to Network and select New Location. NFS. You'll need it again here. IP-The advantage of third-party applications is that they often allow you to save credentials and automatically reconnect when you break the connection.
- 📁 CX File Explorer - features a clean interface and excellent sorting of files by type, which is convenient for the media library.
- 📂 ES Conductor – classic genre, supports many protocols, but requires caution when downloading due to advertising.
- 📀 File Manager+ — Easy and fast manager who works well on budget devices of the Redmi series.
The important thing is permissions. When you first run the app, it will request storage and local network access. In Android 11 and above, which is the MIUI for Redmi 9, access to the local network must be allowed separately in the application system settings, without which you will see a connection error, even if all the parameters are entered correctly.
☑️ Checking connection settings
Setup of video players for streaming playback
Simply opening a file is not enough to be comfortable. To play video from network storage on Redmi 9, it is better to use powerful players such as VLC for Android or MX Player. They have built-in codecs and are able to effectively buffer the flow, minimizing the jerks of the image.
In the player settings, find the Network or Local Network section. Add a new server by specifying the NFS protocol. Once connected, you can add files to the playlist directly from the network drive. VLC, for example, allows you to scan folders and automatically pull up covers and movie information, creating a beautiful media library.
| Parameter | Importance to NFS | Note |
|---|---|---|
| Protocol | NFS | Network File System |
| Port port | 2049 | Standard port. |
| Coding | UTF-8 | For the correct selection of file names |
| Version. | NFSv3 / NFSv4 | Depends on the server. |
If video is slowing down, try resizing the buffer in the player settings. It's also worth checking if the background loads are running, which can take the channel. MX Player is known for its ability to hardware speed up decoding, which is critical for the Helio G80 processor installed in Redmi 9, when playing 4K content.
⚠️ Attention: When in use NFS Make sure that file names do not contain special characters that may be misinterpreted by the protocol.
Solving Typical Connection Problems
Even with the right setup, errors can occur. One of the most common problems on Xiaomi is an aggressive power saving system that kills background processes. If the connection stops after a few minutes, go to the battery settings, find your file manager or player, and set the "No Limits" mode.
Another common error is "Host is unavailable" or "Wait time is over." This often indicates a firewall problem on your computer or router. Check firewall rules: Port 2049 must be open to incoming connections from the LAN. Also make sure the router does not include Wi-Fi client isolation (AP Isolation).
- 🔌 Checking the cable: If NAS connected by cable, make sure it is intact and inserted before clicking.
- 📶 Wi-Fi signal: The signal level on Redmi 9 must be at least two divisions for stable operation NFS.
- ⚙️ Protocol Version: Try to switch the version NFS s v4 on v3 or vice versa in the client settings if the connection is not established.
What to do if the Russian file names are missing?
If nothing helps, try rebooting the network equipment. NAS-systems can accumulate errors in network tables, and a simple reboot often works wonders. It's also worth checking the router's logs for disk errors if you're using a disk. USB-accumulator.
Optimization of connection speed and stability
Optimization is important for Redmi 9 owners who want to make the most of their device. This smartphone supports 802.11ac Wi-Fi standard, which theoretically allows speeds of up to 433 Mbps in the 5 GHz band. Make sure your router broadcasts a 5 GHz network and the phone is connected to it.
Protocol NFS It's sensitive to packet loss, and if you have a lot of interference on your network, you'd better switch to wired connectivity through the network. OTG-adapter, if yours NAS — This is a Raspberry Pi or a mini PC, or a Powerline adapter, but for most scenarios, a high-quality Wi-Fi signal is enough.
In router settings, you can try changing your Wi-Fi channel to a less busy one. Use Wi-Fi app on your smartphone to find a free channel. Connectivity stability is more important than peak speed, so you'd better choose a channel with fewer neighbors, even if the signal is slightly weaker.
💡
Using 5GHz band and NFSv3 protocol often provides the best balance between compatibility and speed on mid-range devices like the Redmi 9.
Security in the use of network resources
When you open up your files through NFS, you need to be aware of security.The NFS protocol doesn't initially encrypt data by transmitting it in plaintext. Within your home network, that's usually okay, but never sprawl NFS ports directly into the Internet without a VPN.
If you NAS Confidential data is stored, set limits on IP-Allow the connection only from the address of your Xiaomi Redmi 9. NFS, specific IP It's also desirable to fix it. IP-phone address in settings DHCP router so that it does not change.
⚠️ Attention: Regularly update the router firmware and software NAS. Vulnerabilities in network protocols are common targets for attackers, and older versions of software may contain known security holes.
It is also recommended to use complex passwords to access the router's admin panel and the NAS itself. Standard passwords like admin/admin change first. Security of your home network begins with simple but effective precautions.
