Installation Process
Flashing the Firmware
Follow these steps to flash the openwrt_s905d_n1 firmware onto your Phicomm N1 device:
- Download the Firmware: Start by downloading the openwrt_s905d_n1 firmware image from a reliable source. Make sure to choose the latest version for optimal performance and security.
- Prepare the Installation Media: Using a tool like Balena Etcher (or dd for Linux), write the firmware image to your USB drive or EMMC storage. It’s crucial to ensure the image is properly written, as any corruption during the process may result in a failed installation.
- Insert the Installation Media: Once the image has been written, insert the USB drive or EMMC storage into the Phicomm N1. If using EMMC, connect it via a USB-to-EMMC adapter.
- Boot the Device: Power on the device while holding down the boot key (typically a specific button or shorting a pin). This will allow you to access the boot menu, where you can choose the storage device that contains the OpenWrt firmware.
- Install the Firmware: Select the installation media from the boot menu, and follow the on-screen instructions to install the OpenWrt firmware onto the Phicomm N1’s internal storage. This process can take several minutes, depending on the storage medium’s speed.
Post-Installation Setup
Once the firmware is installed and the device reboots, you can configure it to suit your needs:
- Access the LuCI Web Interface: To start, open a browser on your computer and navigate to http://192.168.1.1. This is the default IP address for the Phicomm N1 after installing OpenWrt.
- Login: The default login credentials are root for the username and admin for the password. Change the password immediately to ensure your device’s security.
- Network Configuration: After logging in, you will be able to configure both the LAN and WAN interfaces. Depending on your setup, you may need to adjust the DHCP settings, IP address ranges, and routing protocols to match your network’s configuration.

1. Increase PHY Reset Delay
If you experience issues with Ethernet connectivity, increasing the PHY reset delay can help. This adjustment is done by modifying the device tree source (DTS) file. The default delay is often too short for stable connections on some networks, so increasing this delay can improve stability.
2. Enable Flow Control
Flow control is another optimization that can improve Ethernet performance, especially on gigabit networks. Flow control allows the devices to adjust their transmission rates to avoid congestion on the network. Enabling this feature can result in smoother network performance, especially for applications that require high throughput like media streaming or online gaming.
3. Optimize Memory Usage
One of OpenWrt’s strengths is its ability to operate with minimal system resources. However, you can fine-tune the system further by disabling unnecessary services, background processes, or services that are not required for your use case. This reduces the memory footprint, leaving more resources for other tasks.
4. Use Lightweight Packages
To ensure smooth operation, install only the packages that you need. OpenWrt allows you to install or remove packages via the LuCI interface or command-line, so you can install networking utilities, firewall modules, or DNS filtering software, while leaving out any extra bloat.
