my linksys velop's light is solid purple, i can't get it to connect during setup.

Diagnosis

A solid purple light on the Linksys Velop MX5300 indicates that the node is in "Setup Mode." While this is technically a normal state for a new device, a persistent solid purple light that refuses to transition to blue during the setup process typically signals a handshake failure between the node, your mobile device, and the modem. This usually happens because the node is failing to pull a public IP address from the modem or the mobile app is unable to establish a local BLE (Bluetooth Low Energy) connection to the node's internal setup radio. If the light stays purple despite following the app prompts, it is often due to a "zombie" configuration remaining on the hardware from a previous attempt or a conflict with the modem's DHCP server. To confirm this, check if your smartphone can see the "LinksysXXXXX" temporary Wi-Fi SSID in your available networks list. If the SSID is visible but the app cannot "find" the node, the issue is likely a software timeout or a permission restriction on your mobile device. If no SSID is visible, the node's wireless radio is hung in a loop.

How to Fix It

Follow these exact steps to force the MX5300 out of the purple state and into a functional network:

1. Power Cycle the Modem: Unplug your internet modem from the wall. Wait exactly 60 seconds. This clears the ARP cache and ensures the modem is ready to assign a new IP address to the Velop node.
2. Hard Reset the Node: While the node is powered on and glowing purple, locate the Reset button on the bottom of the unit. Use a paperclip to press and hold the button for a full 10-15 seconds. The light will flash red, then turn off, then eventually return to solid purple. This clears any corrupted temporary configurations.
3. Physical Connection: Use a Cat5e or Cat6 Ethernet cable. Plug one end into the modem and the other into the Internet port (the port typically labeled or colored for WAN) on the back of the MX5300. Ensure you hear a physical click.
4. App Permissions: On your smartphone, go to Settings > Apps > Linksys. Ensure that Location Services is set to "Always" or "While Using App" and that Local Network Access (on iOS) is toggled ON. Without these, the app cannot communicate with the purple light state.
5. Initiate Setup: Open the Linksys app. Select "Set up a New Network." When prompted to find the node, keep your phone within 3 feet of the MX5300. If the app asks for a serial number, enter it exactly as it appears on the bottom sticker, avoiding confusion between the letter 'O' and number '0'.

If That Didn't Work

• Bypass the App via Web Browser: If the app continues to fail, use a laptop. Connect the laptop to the Velop's temporary Wi-Fi (LinksysXXXXX). Open a browser and go to 192.168.1.1. This bypasses the mobile app's Bluetooth requirements and allows you to configure the WAN settings directly via the HTTP interface.
• Disable Modem Wi-Fi: If your modem is actually a "Gateway" (a modem/router combo), the built-in Wi-Fi may be causing an IP conflict. Log into your gateway and disable the wireless radios or put the gateway into "Bridge Mode" before attempting the Velop setup again.
• Swap the Ethernet Cable: A faulty pin in the Ethernet cable can prevent the node from seeing the internet, which keeps the light purple even after the app thinks it has connected. Try a different cable to rule out a physical layer failure.
• Check for Firmware Update Loop: Sometimes the node is actually connected but is stuck downloading a critical firmware update. Leave the node plugged in for 30 minutes without touching it; if it transitions from purple to blue on its own, the update has completed.

Heads Up

• Avoid Power Strips: During setup, plug the MX5300 directly into a wall outlet. Some power strips with surge protectors can cause slight voltage drops that interfere with the initial boot sequence and radio calibration.
• Placement Matters: Do not place the node inside a cabinet or directly on top of the modem. Keep at least 3 feet of separation between the modem and the Velop to prevent signal interference during the handshake process.
• DNS Conflicts: If you have a static IP configuration from your ISP, you must enter these settings manually in the "Advanced Settings" section of the app after the initial connection is established.
• Avoid Double NAT: If you have another router between the modem and the Velop, you will experience "Double NAT," which causes gaming and VPN issues. Always ensure the MX5300 is the first device connected to the modem.
