# CONNECT SERIES - Link 1 (LW930/LW500) Flashing Red

## This article provides fixes for when your Link 1 (LW930/LW500) is flashing red or is not connecting to our servers.

#### 🔌 Link 1 (LW500 / LW930) – Flashing Red

A **flashing red light** on a Link 1 is most commonly caused by a **power supply issue**, not a network issue.

### ⚠️ Most Common Cause – Power Supply Failure

This often happens:

• After a **power cut**  
• On **older units** (Link 1 was discontinued in 2019)

👉 In most cases, the **power adaptor has failed or degraded**.

### ✅ Fix:

• Replace the power adaptor with the correct rating:  
**12V 0.3A**

• These are still available, so please **contact support to obtain a replacement**

---

### 🌐 Less Common Cause – Network / Router Changes

In some cases, flashing red may occur after:

• Changing your **router**  
• Switching **internet provider (ISP)**

### ✅ Fix:

• Try **restarting your router**  
• If needed, **set up port forwarding** (see below)

👉 However, always try the **power adaptor first**, as this is the most common cause.

---

### ⚙️ Advanced (Optional) – Port Forwarding

If required, the following UDP ports can be forwarded:

• 69  
• 2011  
• 2013

This can help restore communication, but is **rarely needed**
