Step 1:

  • Mercusys USA uses your Original Proof of Purchase to validate warranty eligibility. Keep a digital or physical copy of your receipt from authorized US retailers like Amazon, Newegg, or Walmart; without it, the warranty start date defaults to 3 months from the manufacturing date.

  • Find the Serial Number (S/N) and MAC address on the label under your device. This is mandatory for registering your claim and helps technical support verify the specific hardware version of your unit.

  • The warranty is only valid for products purchased and used within the United States from authorized sellers. International models or products bought from unauthorized third-party resellers are not covered by Mercusys USA.

Step 2:

  • Connect your system to the Mercusys App to run a diagnostic check. Many "performance issues" are often resolved by a simple firmware update or an automated channel optimization through the app.

  • Before filing a claim, hold the "Reset" button for 10 seconds. If the device remains unresponsive or fails to broadcast a signal after a factory reset, it confirms a potential hardware-level defect.

  • Note the status of the indicator lights (e.g., solid orange or blinking red). Providing these specific details to the technical team will significantly speed up your RMA approval.

Step 3:

  • Reach out to the team through Contact Us directly by visiting the Mercusys Support Portal or email with your model number, S/N, and a description of the issue.

  • If troubleshooting fails, the support team will issue a Return Merchandise Authorization (RMA) number. Do not ship your device until you have received this official confirmation.

  • Package the device, its power adapter, and antennas securely. You are typically responsible for the shipping costs to the service center; Mercusys will then repair or replace the unit and return it to you at their expense.

Mercusys Warranty Period:

  • Limited warranty: typically 2–3 years, depending on the product.
