Rein and Shine Interference

In our constantly evolving world, a stable and fast internet connection is essential for both teaching and carrying out day to day tasks. If your, connectivity drops intermittently, this can leave users being unable to carry out their work effectively. Two possible culprits behind connections intermittently dropping are are REIN and SHINE.

Though these terms may sound technical, understanding them can help you identify and address the problems affecting your connection. In this blog, we'll break down what REIN and SHINE are, how they can impact your broadband connection, and what you can do to diagnose them.

What is REIN?

Rein (Repetitive Electrical Impulse Noise) refers to a type of electrical noise that can interfere with broadband signals, causing disruptions to your internet connection. This noise is characterised by its repetitive nature, where electrical impulses occur at regular intervals.

These impulses can originate from a variety of sources, such as faulty electrical appliances, power lines, or even fluorescent lights. When these impulses occur, they can disrupt the flow of data between your home and your internet line.

Common Sources of REIN:

• Faulty Electrical Devices: Devices like old televisions, fridges, or even power tools can emit REIN.
• Poor Wiring: Inadequate or damaged electrical wiring can also contribute to REIN.
• External Factors: Power lines or nearby electrical installations can introduce REIN into your broadband line.

How REIN Affects Your Broadband Connection

The impact of REIN on your broadband connection can vary depending on the intensity and frequency of the noise. In mild cases, you might notice slight slowdowns or occasional drops in connection. However, in more severe cases, REIN can cause frequent disconnections, making it difficult to maintain a stable internet connection.

What is SHINE?

While REIN consists of continuous, repetitive noise, SHINE (Single High Impulse Noise Event) refers to sudden, high-intensity bursts of electrical noise. Unlike REIN, which is ongoing, SHINE events are typically isolated incidents that occur sporadically. Despite their brief nature, SHINE events can be powerful enough to cause significant disruptions to your broadband connection. These events are often caused by a sudden surge in electrical power, which can occur when certain devices are turned on or off.

Common Sources of SHINE:

• Power Surges: Sudden increases in power, often caused by large appliances like washing machines or air conditioners, can trigger SHINE
• Electrical Switching: The operation of high-powered switches or circuit breakers can also lead to SHINE events.

How SHINE Affects Your Broadband Connection

SHINE events can have an immediate and noticeable impact on your broadband connection. Because these are high-intensity noise events, they can cause your connection to drop entirely for a brief period. Even a single SHINE event can lead to a significant disruption, especially if it coincides with critical activities such as video calls or online browsing.

While SHINE is less common than REIN, its effects can be more disruptive. The challenge with SHINE is its unpredictability. Because it occurs suddenly and without warning, it can be difficult to pinpoint the source or anticipate when it might happen again.

Diagnosing REIN

Diagnosing REIN involves a process of elimination and requires some patience, as the interference is often caused by devices that you might not immediately suspect.

1. Monitor Your Connection:
   • Use the session history tab within the Panel to monitor disconnections and slowdowns. Take note of when these issues occur.
   • Keep track of the time of day and any patterns in the disruption. For example, does the interference coincide with when certain devices are in use?
2. Turn Off Electrical Devices:
   • Begin by turning off all electrical devices including lights, appliances and electronics.
   • Gradually turn each device back on, one by one, while monitoring your broadband connection. If your connection drops or slows significantly when a specific device is turned on, that device may be the source of the REIN.
3. Check for External Sources:
   • If you’re unable to identify the source within your home, the interference may be coming from outside. Neighbours’ devices, streetlights, or power lines can also cause REIN.
   • Talk to your neighbours to see if they are experiencing similar issues. If multiple sites are affected, it could be an external source.
4. Inspect Your Wiring:
   • Poor or damaged wiring can exacerbate REIN. Check wiring around your site, particularly around your router and phone line, to ensure everything is properly connected and in good condition.
5. Use a Portable Radio:

• • A portable AM radio can be used to detect REIN. Should you still own one, you can tune it to a frequency with no station (so you just hear static) and walk around your home. If you hear a buzzing noise near a particular device, that could be the source of the interference.

Step-by-Step Guide to Diagnosing SHINE

Diagnosing SHINE is more challenging than diagnosing REIN because SHINE events are less predictable and more sporadic. However, there are still steps you can take to identify the cause.

1. Monitor for Sudden Disruptions:
   • Keep a close eye on when disruptions occur. SHINE events are usually associated with specific actions, such as turning on a high-powered appliance or experiencing a power surge.
   • Record the exact time of the disruption and try to correlate it with any activities or electrical events that occurred at the same time.
2. Check Your Circuit Breaker:
   • SHINE can be caused by sudden power spikes or drops. Check your circuit breaker for any signs of tripping or unusual behaviour.
   • If you notice a pattern, such as the connection dropping every time a particular appliance is used, that appliance might be causing SHINE events.
3. Inspect High-Powered Appliances:
   • Appliances such as washing machines, microwaves and air conditioners can cause SHINE. Unplug these appliances and see if the disruptions cease when they are not in use.
4. Consider Environmental Factors:

• • External factors such as lightning strikes or work being done on nearby power lines can also cause SHINE. If your disruptions coincide with storms or nearby construction, these might be the source of the problem.
