What Comes with the RAX2300?

Before connecting anything, make sure you have the required hardware.

According to the current Raxxio product page, the RAX2300 package includes the set-top box, power adapter, HDMI cable, remote control, two AAA batteries, and an IR extender cable.

That means you can complete the basic TV connection without purchasing another HDMI cable separately.

The device itself uses Linux 4.9 and is built around the Hisilicon 3798MV300 chipset with 1GB RAM and 8GB ROM. Raxxio also lists 4K HDR support, LAN/Wi-Fi connectivity, HDMI 1.4, USB 2.0, AV output, SPDIF coaxial audio, and RS232 connectivity.

Quick RAX2300 First-Time Setup

For most users, the initial setup can be broken into five basic steps:

Connect the RAX2300 to the TV using HDMI.
Connect the supplied power adapter.
Insert the batteries into the remote.
Select the correct HDMI input on the television.
Connect the RAX2300 to the internet using Wi-Fi or Ethernet.

Once the home screen appears, you can review the display, network, time, and other available settings.

The exact wording of menu items can vary by firmware version, so use the closest matching option shown on your device.

Step 1: Connect the RAX2300 to Your TV

Start with the TV turned off if possible.

Connect one end of the HDMI cable to the HDMI output on the RAX2300 and the other end to an available HDMI input on your television.

Then connect the supplied power adapter to the device.

Turn on the television and use the TV remote to select the HDMI input where the RAX2300 is connected.

For example, if you plugged the cable into HDMI 2, choose HDMI 2 from your TV’s input/source menu.

After a short startup sequence, the RAX2300 interface should appear.

Step 2: Prepare the Remote Control

Insert the two AAA batteries into the RAX2300 remote.

Most first-time navigation is handled with:

Arrow keys
OK/select button
Home
Back/Exit
Settings
Volume
Channel controls
Number keys

If you use the supplied IR extender, make sure the receiver is positioned where the remote signal can reach it.

This can be useful when the set-top box is placed behind the television or inside an entertainment cabinet.

Step 3: Connect the RAX2300 to Wi-Fi

One of the most common setup questions is:

How do I connect RAX2300 to Wi-Fi?

Open the device settings and look for a section labeled something similar to:

Network, Internet, Wi-Fi, or Network Settings.

Turn Wi-Fi on if it is disabled.

Choose your home Wi-Fi network from the available list, enter your password, and confirm the connection.

The current RAX2300 product information lists built-in wireless connectivity as well as LAN networking.

Which Wi-Fi Band Should You Use?

If your router offers both 2.4GHz and 5GHz networks, the best option depends on your setup.

5GHz Wi-Fi is usually preferable when the router is reasonably close to the RAX2300 because it can provide higher throughput and less interference.

2.4GHz Wi-Fi can sometimes provide better range through walls or across longer distances.

The important factor is signal stability.

A strong 2.4GHz connection may perform better than a weak 5GHz connection.

Step 4: Set Up Ethernet for a Wired Connection

For users who want the most consistent network connection, Ethernet is often the easiest option.

Connect an Ethernet cable from your router or network switch to the LAN port on the RAX2300.

The device should normally detect the wired connection automatically.

If it does not, open the network settings and check whether the Ethernet or wired-network option is enabled.

A wired connection can be useful when:

The router is close to the television
Wi-Fi signal strength is inconsistent
Your home has many wireless devices
You frequently stream high-resolution video
You want to reduce wireless interference

Raxxio lists LAN support among the RAX2300’s networking capabilities.

Wi-Fi or Ethernet: Which Is Better for RAX2300?

There is no single answer for every home.

Use Wi-Fi when cable routing is inconvenient, and your wireless signal is strong.

Use Ethernet when you want a direct network connection, and your router is accessible.

If you experience repeated buffering or connection drops while using Wi-Fi, testing Ethernet is one of the easiest troubleshooting steps.

Remember that streaming performance also depends on your internet plan, network traffic, source quality, service availability, and server conditions—not just the set-top box.

Step 5: Configure Display Resolution

After connecting the RAX2300 to the television, review the video or display settings.

Look for options such as:

Display
Screen
HDMI
Resolution
Video output

Choose a resolution supported by your television.

If you have a compatible 4K television, you can select the appropriate 2160p/4K output option where available.

The RAX2300 product page lists support for 4K UHD / 2160p HDR output.

Should You Always Select 4K?

Not necessarily.

If your TV is 1080p, choose 1080p.

If your TV supports 4K, use a compatible 4K setting.

Selecting a resolution higher than your TV supports can lead to a blank screen, unstable image, or an unsupported-resolution message.

Always match the output to the capabilities of your television.

Check the Screen Aspect Ratio

If the image looks stretched, cropped, or does not fill the screen correctly, review the aspect-ratio or screen-size settings.

Common options may include:

Auto
16:9
Fit to screen
Original
Full

For most modern widescreen televisions, 16:9 or Auto is generally appropriate.

You may also need to adjust the TV’s own picture-size setting.

Set the Correct Time and Date

A small setting that is easy to overlook is the system time.

Go to the system settings and confirm:

Time zone
Date
Time
Automatic time setting, if available

Correct system time can help with electronic program guides, scheduled functions, logs, and time-based applications.

Review Audio Settings

If video is working but there is no sound, check both the RAX2300 and television audio settings.

The current RAX2300 specification lists HDMI audio output as well as SPDIF coaxial and analog AV connections.

For a standard TV setup, HDMI usually carries both video and audio.

If you use an external sound system, soundbar, receiver, or SPDIF connection, select the appropriate audio output option in the settings.

Also confirm that:

The TV is not muted
The RAX2300 volume is turned up
The correct audio output is selected
Your external audio device is on the correct input

Connecting USB Devices

The RAX2300 includes USB connectivity. Raxxio currently specifies a USB 2.0 interface.

Compatible USB storage may be useful for supported local media files or other device functions.

When connecting USB storage:

Insert the USB drive.
Wait for the device to recognize it.
Open the appropriate media/file section.
Select the supported file you want to access.

Avoid unplugging USB storage while data is actively being read or written.

First-Time Network Test

After connecting to Wi-Fi or Ethernet, test the network before changing many other settings.

Open a supported online feature or network-status screen and verify that the device is actually connected.

If the network shows connected but online content does not load:

Restart the router
Restart the RAX2300
Re-enter the Wi-Fi password
Test Ethernet
Check whether other devices can access the internet
Confirm the service you are trying to use is currently available

This helps separate a device issue from a router, internet, or provider-side issue.

Keep the RAX2300 Firmware Updated

If a firmware or system-update option is available, check it periodically.

Updates may contain:

Stability improvements
Compatibility changes
Bug fixes
Security updates
Interface improvements

Do not disconnect the power while an update is in progress.

If the device is functioning properly, avoid installing unofficial firmware from unknown sources.

Use official or trusted update sources intended for your exact hardware.

How to Improve RAX2300 Wi-Fi Performance

If your wireless connection feels inconsistent, try these practical adjustments.

Move the Router Closer

Distance and walls can weaken Wi-Fi.

Avoid Hiding the Box Behind Metal Objects

Large metal surfaces and tightly enclosed cabinets can affect wireless reception.

Try 5GHz Near the Router

When signal strength is good, 5GHz can be useful for high-bandwidth streaming.

Try 2.4GHz at Longer Range

If 5GHz becomes unstable at a distance, test the 2.4GHz network.

Reduce Network Congestion

Large downloads, cloud backups, gaming, and multiple simultaneous 4K streams can consume bandwidth.

Test Ethernet

If Ethernet immediately solves the issue, the problem was likely wireless rather than the box itself.

What to Do If the TV Shows “No Signal”

A no-signal message usually means the television is not receiving an HDMI image.

Check the following:

Is the RAX2300 powered on?
Is the HDMI cable connected firmly?
Is the TV using the correct HDMI input?
Can you test another HDMI port?
Can you test another HDMI cable?
Does restarting the RAX2300 help?

If the output resolution was changed just before the problem started, the TV may not support the selected resolution.

What to Do If Wi-Fi Will Not Connect

Start with the basics:

Confirm the Wi-Fi password
Restart the router
Restart the RAX2300
Forget the network and reconnect
Move closer to the router
Try the other Wi-Fi band
Test Ethernet

If every other device connects normally but the RAX2300 does not, review its network configuration again.

What to Do If Video Buffers

Buffering does not automatically mean the RAX2300 hardware is faulty.

Possible causes include:

Slow internet
Weak Wi-Fi
Network congestion
Source-server congestion
High-resolution content
Temporary service problems

Test another online source and, if possible, compare Wi-Fi with Ethernet.

This gives you a clearer idea of where the issue originates.

Best RAX2300 Setup for a 4K TV

For a straightforward 4K home setup:

Connect via HDMI
Choose a supported 2160p/4K display mode
Use Ethernet or strong 5GHz Wi-Fi
Keep firmware current
Use supported media formats and services
Keep the device ventilated
Avoid covering the top vents

The RAX2300 has a compact 106 × 106 × 20 mm chassis and uses passive heatsinking according to Raxxio’s current specifications.

Good airflow is still important for any media device during long viewing sessions.

Important: RAX2300 Is a Hardware Device

The RAX2300 should be treated as a Linux streaming/set-top box hardware device.

Streaming services, subscriptions, accounts, or content access may require separate user accounts and may vary by region, service availability, firmware, and provider.

This distinction is useful for both buyers and existing users: the box provides the hardware platform and connectivity, while individual services control their own subscriptions and content.

Why This Setup Matters

Many performance problems can be avoided during the first ten minutes of setup.

A correct HDMI connection, suitable resolution, reliable network connection, updated system, and properly configured audio can make the difference between a frustrating installation and a straightforward one.

Rather than changing multiple advanced settings immediately, start with the essentials:

Display → Network → Audio → System → Services

Once those basics are working, you can personalize the rest of the device.

Final Thoughts

The RAX2300 setup process is relatively straightforward when you approach it in the right order.

Start by connecting HDMI and power. Confirm the correct television input. Connect to Wi-Fi or Ethernet. Match the display resolution to your TV. Review audio and time settings. Then test your network before moving on to additional services or personalization.

With Linux 4.9, 1GB RAM, 8GB ROM, 4K HDR support, wired LAN, Wi-Fi, HDMI, and USB connectivity, the RAX2300 provides the core hardware needed for a compact TV streaming setup.
