How to connect NFS Xiaomi devices: from phone to Mi Box

Network storage by protocol NFS (Network File System allows Xiaomi devices – whether they are smartphones MIUI, Mi TVs TV Or Mi Box, which is to access files on a server as if they were stored locally, and this is especially useful for streaming movies in the video game. 4K HDR, But standard instructions often miss nuances, from firmware differences to router features.

In this article, we will discuss all the current ways of connecting. NFS to Xiaomi devices in 2026 year – from manual configuration via Termux to the use of built-in features MIUI 14/15. You will learn how to bypass manufacturer restrictions, fix Permission denied or Mount failed errors, and optimize data transfer speeds. NFS Mi Box S/4K and Mi TVs TV Q2/Q1E, Where the process is different from mobile devices.

1. What is it? NFS Why is it better than Samba for Xiaomi?

Protocol NFS (Originally developed by Sun Microsystems in 1984, it was originally designed for Unix systems, but is now supported by most network storage systems, from Synology. NAS The Raspberry Pi home servers, unlike the SMB (Samba, which is often used in Windows networks, NFS offer:

• 🚀 Higher speed for small file transfers (20-40% faster in tests with Xiaomi Mi 11 Ultra).
• 🔒 Flexible access rights at the user and group level (relevant for multi-user services) NAS).
• 📱 Better integration with Android Linux core, which reduces the load on the device’s processor.
• 🎬 Support for hard links critical for working with torrent clients such as qBittorrent.

But NFS There are also disadvantages: it does not encrypt traffic by default (unlike the one that is not used for the purpose of the system). SMB 3.0+), And the setup requires knowledge of the command line. For Xiaomi, that means connecting through the command line. NFS Frequently breaks down after updates MIUI or reset.

⚠️ Note: If your router is using IPv6, server NFS set up only IPv4, Connection will be impossible. Check network settings in Settings → Wi-Fi → Additionally.

Preparation of the server NFS Xiaomi

Before connecting Xiaomi to NFS, You need to set up the server properly. Let's look at two popular scenarios: home. NAS (Synology/QNAP) Linux-based servers (e.g. Ubuntu Server).

Adjustment NFS synology NAS

1. Open the Control Panel of your NAS and go to the General folders section.

2. Select the folder you want to share and click Properties → Permits NFS.

3. Add a rule with parameters:

• 📌 IP-client: 192.168.1.0/24 (specific IP your Xiaomi).
• 🔧 Privileges: Reading/Writing.
• 🔄 Coding: UTF-8 (It is important for the correct display of Cyrillic).
• 🔒 Anonymous UID/GID: 0 (root-access).

4. Save settings and restart the service NFS control panel → Terminal and SNMP → Energize the service NFS.

Adjustment NFS Linux server

If you have a server on Ubuntu/Debian, run it in the terminal:

sudo apt update && sudo apt install nfs-kernel-server


sudo nano /etc/exports

Add a line (replace) /path/to/folder real-world):

/path/to/folder 192.168.1.0/24(rw,sync,no_subtree_check,no_root_squash)

Then apply the changes:

sudo exportfs -a


sudo systemctl restart nfs-kernel-server

⚠️ Attention: Parameter no_root_squash It gives Xiaomi devices root rights to the folder. Use it only on trusted networks!

3. Connection NFS Xiaomi (MIUI)

Unlike the Mi Box, Xiaomi smartphones don’t have built-in support. NFS. However, there are three working methods:

Method 1: Through Termux (for advanced users)

1. Install Termux from F-Droid (the version from Google Play is outdated).

2. Update packages and install nfs-common:

pkg update && pkg upgrade


pkg install nfs-utils

3. Create a mount point and connect NFS:

mkdir ~/nfs_share


sudo mount -t nfs 192.168.1.100:/path/to/folder ~/nfs_share -o soft,intr,rsize=8192,wsize=8192

4.To mount automatically when Termux is started, add a command to ~/.bashrc.

Method 2: Through the annex "NFS Manager"

1. Download. NFS Manager from Google Play.

2 Enter the server data:

• 🌐 IP-address: 192.168.1.100 (example).
• 📁 Exportable folder: /path/to/folder.
• 🔑 Port: 2049 (default).

3. Press Mount and confirm the rights of Superuser (root required).

Method 3: Through Total Commander + plugin

1. Install Total Commander and plugin LAN Plugin.

2. In the plugin settings, select NFS enter:

• 🖥️ server: IP yours NAS.
• 📂 folder: /path/to/folder.
• 👤 User: Anonymous or your username on the server.

3. Connect and copy files as if from local storage.

Make sure your smartphone and server are on the same subnet|Check that the service is running on the server NFS|Open port 2049 in the router firewall|Set up static. IP Xiaomi-based-->

4. Connection NFS To Mi Box and Mi TV

Media set-top boxes Mi Box S/4K and Mi TVs TV Q2/Q1E support NFS "It's out of the box, but it's hidden in the developers. Here's how to activate it:

Inclusion NFS on Mi Box (Android) TV)

1. Go to Settings. → The device → About the programme.

2. Click 7 times on the Build Number to enable Developer Mode.

3. Return to Settings → The device → For developers and include:

• 🔧 Debugging by USB.
• 🌐 Network debugging.
• 📡 Unknown sources (for installation) APK).

4. Install File Commander or X-plore from Google Play and connect in the settings NFS:

• 📌 server: IP yours NAS.
• 📁 folder: /path/to/folder.
• 🔑 Protocol: NFS v3 (recommended for stability).

Adjustment NFS on Mi TV (PatchWall)

1. Open Settings. → The device → On TV.

2. Activate Developer Mode (similar to Mi Box).

3. Install. ES The guide through Send Files to TV (appendix).

4.B. ES Conductor select Network → NFS and enter the server data.

⚠️ Attention: On Mi TV Firmware older than 2023.10 may not work NFS v4. Use it. v3 or update the software.

5. Solving common mistakes

Even with the right setup, the connection NFS Xiaomi may end in errors. Let's analyze the most common:

If the error persists, check the server logs with the command:

sudo tail -f /var/log/syslog | grep nfs

💡

To expedite the work NFS On Xiaomi, add rsize options to the mounting options=32768,wsize=This will increase the size of the read/write buffer and reduce delays.

6. Speed optimization NFS Xiaomi

By default. NFS It uses small transmission buffers, which limits speed.For Xiaomi devices with gigabit Wi-Fi (e.g. Xiaomi 13 Pro or Mi Box) 4K) recommend:

• 🚀 Increase the size of the buffer: use the rsize settings=65536,wsize=65536.
• 📶 Switch to 5 GHz Wi-Fi: NFS It is sensitive to delays and the 2.4 GHz range is often overloaded.
• 🔌 Use wired connection: for Mi Box, connect the Ethernet adapter via USB.
• 🔄 Disable atime: Add noatime to the mounting option to reduce disk calls.

To test the speed, use the command:

dd if=/dev/zero of=~/nfs_share/testfile bs=1M count=100

The normal speed for a gigabit network is 80-110 MB/s. If the value is below 30 MB/s, check the router settings (turn off QoS or Bandwidth Control).

💡

For streaming. 4K-video NFS Minimum speed required is 50 MB/s. If the speed is lower, use it. SMB or.

Alternatives NFS Xiaomi

If the setting NFS It seems too difficult to consider alternatives:

• 📂 SMB (Samba: Easy to set up, but slower. Supported by all Xiaomi devices without additional apps.
• ☁️ WebDAV: Works through HTTP/HTTPS, It's good for remote access. Configure with Solid Explorer.
• 🔗 SSHFS: He's mounting a remote folder on SSH. Safer. NFS, But it requires more resources. Install it via Termux:

pkg install sshfs


sshfs user@192.168.1.100:/path/to/folder ~/sshfs_mount

For Mi Box media, the best alternative is Plex or Jellyfin, which transcodes video on the fly and doesn't require folders to be mounted.

8 Safety in the use of NFS

NFS It transmits data in an open form, which makes it vulnerable to MITM-- Attacks (traffic interception) to protect the connection:

• 🔐 Use it. VPN: Set up WireGuard or OpenVPN on your router so that all traffic between Xiaomi and the server is encrypted.
• 🌍 Restrict access by IP: V /etc/exports Only give the trusted ones IP-address.
• 🛡️ Turn it off. NFS v2: An outdated version of the protocol has critical vulnerabilities. v3 or v4.
• 🔄 Update your server regularly: In Synology, enable automatic updates DSM, Do it on Linux:

sudo apt update && sudo apt upgrade -y

For maximum safety, consider moving to NFS over TLS (requires stunnel or IPsec configuration).
