Modern smartphones like the Xiaomi Mi 9 Pro are often used not only for communication, but also as multimedia centers that require access to large amounts of data. Built-in memory may be scarce, and here network storage that works on the protocol comes to the rescue. NFS (Network File System, but the standard shell MIUI It does not always offer a convenient interface for connecting such resources out of the box».
Setting up NFS on your device allows you to access files on your home server, NAS, or computer without having to copy them to your phone. This saves precious space and allows you to stream heavy, high-resolution video files directly. Owners of the Mi 9 Pro model with its powerful processor and fast Wi-Fi 6 module can get excellent data transfer speeds with the right configuration.
In this guide, we will discuss how to get around system constraints and establish a stable connection, which applications are best suited for this task and which network settings you need to check first, and fine-tuning will ensure that your media files and documents work smoothly.
Preparation of network infrastructure
Before you start setting up the smartphone itself, you need to make sure that your local network is ready to work with the protocol. NFS. Router and server part (whether it is a computer with a computer) Windows/Linux or NAS-system) must be on the same subnet. Make sure that the server is running the service NFS The ports are open, usually the port. 2049.
It is important to check the firewall settings on the receiving device. Often it is the system locks that prevent successful connection, even if all passwords are entered correctly. IP-address for your server so that the path to the files does not change after the router restarts.
⚠️ Warning: Make sure your router supports multicast traffic if you plan to use automatic device detection.In some router models, this feature is disabled by default for security reasons.
Connection stability is directly dependent on signal quality. Since the Xiaomi Mi 9 Pro supports dual-band Wi-Fi, it is highly recommended to use a 5 GHz network. This will achieve speeds comparable to wired connection, which is critical for playback. 4K-Video or work with heavy archives.
Choosing the Right File Manager
The MIUI shelled conductor is basic and often can't handle NFS directly or is unstable. You'll need a third-party app to work properly. The market offers a lot of solutions, but the Mi 9 Pro is best served by dedicated network protocol managers.
One of the best options is MiXplorer or Solid Explorer, which have built-in codecs and caching mechanisms that make it faster to open file previews, and they allow you to create permanent shortcuts for network folders, making them available as local partitions.
- 📁 MiXplorer is a free, open source solution that supports a huge number of plugins and protocols.
- 🛡️ Solid Explorer is a paid but powerful application with encryption and a convenient two-panel interface.
- 🚀 CX File Explorer – easy and fast option with excellent visualization of occupied space on network disks.
When you install any of these applications, the system can request extended permissions. In MIUI, this is normal, because Android strictly controls access to the file system. You will need to allow access to all files so that the application can mount network drives.

Use the Favorites feature in the file manager to add frequently used network folders to the home screen for quick access.
Step-by-step instructions for connecting NFS
The connection process may vary slightly depending on the file manager you choose, but the overall logic remains the same. Consider the algorithm on the example of a popular manager, which is often installed on the Xiaomi Mi 9 Pro. First, open the application and find the button to add new storage.
☑️ Checklist of connection
In the protocol selection menu, specify NFS. The system will ask you to enter the host address. IP-The address of your server is manually located, even if a search on the network found the device.
Once you enter the address, click the Connection button. If the server requires authentication, enter your login and password. In some cases, you can choose Guest or Anonymous mode for home use, if your NAS or PC security settings allow it.
| Parameter | Default value | Recommended value | Where to find out. |
|---|---|---|---|
| Port port | 2049 | 2049 | Router/NAS settings |
| Protocol | NFS v3 | NFS v4 | Server settings |
| Coding | UTF-8 | UTF-8 | System settings |
| timemouth | 30 seconds. | 60 seconds. | Application settings |
If the connection is successful, you'll see a network folder in the list of available drives, you can now copy files, run videos, or edit documents directly, and the response rate will depend on the loading of the channel and the power of the server.
Configure access rights in MIUI
Shell MIUI It is known for its aggressive energy saving policy, which can break background connections, so that your Xiaomi Mi 9 Pro does not lose touch with the other devices. NFS-If you're on the server, if you're off the screen, you need to make changes to the battery settings. → Battery and productivity.
Find your file manager on the list and select the "No Limits" option, which will prevent the system from "sleeping" the application and interrupting network sockets, without which long-term file transfers may be interrupted in the middle.
⚠️ Attention: In new versions MIUI Without this right, after restarting the phone, the file manager will not be able to restore the connection automatically.
Another important aspect is the background permits. In the Security menu, check if the background activity restriction for the selected explorer is worth it. Also make sure that the Display Over Other Windows permission is enabled if you plan to use pop-ups to manage files.
Hidden DNS settings
Diagnostics and problem-solving
Even with the right setup, there can be connection errors. The most common problem is "Host unreachable" or connection timeout. This almost always indicates a problem with the network, not with the Mi 9 Pro phone itself. Check if the server is visible from other devices on the network.
If you see files that don’t open or video slows down, try lowering the bitrate of the stream in the player or file manager settings. It’s also worth checking if the smartphone’s Wi-Fi module overheats when you’re on a long load, even though the Mi 9 Pro has a good cooling system.
- 🔄 Reboot the service - try restarting the service NFS server-side.
- 🔌 Cable change – if the server is connected via cable, check its integrity.
- 📡 Wi-Fi Channel – switch router to less busy channel in 5GHz band.
You can often find more detailed information about the bug in the application logs, looking for error codes like EACCES (no access permissions) or ETIMEDOUT (exceeding time), which will tell you which direction to go when you search for a solution.
💡
90% of NFS problems on Xiaomi are related to MIUI power saving settings or blocking ports in antivirus on PCs.
Optimization of data transfer speed
For maximum performance on the Xiaomi Mi 9 Pro, it is recommended to use the NFS v4 protocol, which works better with unstable connections than the v3 version. However, if your server is old, you may have to go back to v3 for compatibility.
The size of the read buffer also plays a role, because in advanced file managers settings, you can increase the size of the buffer, and this allows you to download large chunks of data before playing them, which eliminates the jerks when you watch high-resolution videos.
⚠️ Warning: Do not set too high buffer values if your router has little RAM.This can cause the router buffer to overflow and speed drops for all devices on the network.
Use static. IP-This will allow you to create permanent traffic prioritization (QoS) rules, ensuring that streaming video from the router NFS Always take precedence over background downloads.
Security of network connection
NFS was originally designed for trusted networks and has no built-in data encryption, which means that all files transmitted can be intercepted if an attacker gains access to your Wi-Fi. Therefore, using a strong password on a Wi-Fi network with WPA3 or WPA2 encryption is mandatory.
Never open the ports. NFS (2049) directly to the Internet. Use remote access VPN-Xiaomi Mi 9 Pro does a great job with encryption VPN-traffic without significant loss of speed thanks to a powerful processor.
Regularly update your router firmware and your network storage software. Manufacturers often close vulnerabilities that could allow unauthorized access to your data through file protocols.
