How to Fix a Broken Router Antenna?

Fixing a broken router antenna is a straightforward process that can help restore functionality to your router.

This guide will provide you with the solutions and step-by-step instructions to address the issue.


  • Replace the broken antenna with a compatible one following the instructions of the manufacturer.
  • Repair minor damages in the antenna such as straightening bents and soldering disconnected parts or refixing them using adhesive.
  • Check if the connection of the cable to the antenna and the router port is broken and solder it securely.
  • Upgrade to a high-gain antenna if you still get poor signal coverage and strength after repair.
  • Contact customer support if all your efforts fail for proper guidance.

What Happens If Router Antenna Breaks?

When a router antenna breaks, you’ll likely experience connection problems, frequent dropouts, dead zones, and a noticeable decline in signal quality leading to slower internet speeds.

Additionally, a broken router antenna can result in:

  • Limited coverage area with weak or no signal
  • Noise and interference disrupting device performance
  • Increased vulnerability to security breaches and unauthorized access
  • Higher stress on the router, potentially causing overheating and faster wear and tear

In summary, a broken router antenna diminishes user experiences and may lead to long-term router issues.

Ways to Fix a Broken Router Antenna

The easiest way to fix a broken router antenna is to replace it with a compatible one.

Alternatively, you can:

  • Check and secure cable connections
  • Upgrade to a high-gain antenna
  • Contact customer support for further guidance or a replacement
  • Repair minor damage by straightening, reattaching, or soldering

Method 1: Replace the Broken Antenna with a Compatible Antenna

If your antenna is simply broken and can be unscrewed, replacing the broken antenna with a compatible antenna will easily allow you to restore the normal functionality of the router.


  • Identify the type of your router antenna, omnidirectional or dipole, by referring to your router user manual.
  • Buy a similar replacement antenna that matches the specs and type of the broken original antenna.
  • Turn the Router off and disconnect it from the power source for your safety.
  • Unscrew the broken antenna carefully to remove it. Depending on the model type, it can also be removed by detaching it from the antenna port in the router.
  • Gently screw the new antenna or attach it to the router’s antenna port.

Note: Secure the antenna but do not overtighten it.

Method 2: Repair Bent Elements

If you have the proper tools, you can make some minor repairs to the broken antenna, such as fixing the broken wires or the bent external elements.


  • Remove the rubber caps on the screws, if any.
  • Remove the screws from the router.

  • Replace the enclosure and refix the screws and rubber caps on them.

Method 3: Inspect and Secure Cable Connections

There may be some loose cable connections causing performance issues. Check the wires and solder them.


  • Turn the router off and open the enclosure as before.
  • Check the cable connections of the antenna to the router’s PCB.
  • Use a soldering iron to remove them and then securely reaffix them on the PCB.

Method 4: Check the Internal Part of the Antenna

Check the internal part of the antenna. It can be broken or bent and affect the performance of the router.


  • Unscrew the antennas.
  • Open the internal part of the antenna from its joint.

Method 5: Replace the Broken Antenna Enclosure

Assuming that a portion of the internal part of the antenna is okay and the enclosure is broken and irreparable, you can fix it quickly with this impromptu solution using the case of a ballpoint pen!


  • Open the router.
  • Check the connection of the antenna wire on the PCB.
