Dear TP-Link Support Team,

I am experiencing a critical issue with my TP-Link RE650 (Hardware Version V1.0).

Problem Description:

• The extender does not broadcast the 5GHz network at all.

• The 5G LED on the device never turns on.

• No 5GHz SSID appears on any of my devices, including smartphones and laptops.

• The 2.4GHz network functions normally.

Details:

• My main router’s 5GHz network works correctly.

• The issue persists regardless of the location of the extender. Even when placed very close to the router, the 5GHz network does not appear.

• The extender has been factory reset multiple times, with no change.

• Firmware currently installed: RE650(UK)_V1_190521 (latest official for V1)

• Tested devices: multiple smartphones and laptops, all fail to detect 5GHz from the extender.

Troubleshooting Steps Already Taken:

1. Restarted both the router and the extender multiple times.

2. Factory reset of the RE650.

3. Verified the 5GHz SSID and password settings.

4. Tested various positions and distances from the main router.

5. Verified the extender is using the latest firmware for V1 (2019 release).

6. Checked main router 5GHz network; it works correctly and broadcasts normally.

7. Attempted different channel settings on the router, including safe lower channels (36–48).

Observations:

• Despite all attempts, the 5GHz network never appears on the extender.

• The 5G LED remains off at all times.

• The 2.4GHz network is stable and functional.

Thank you for your assistance.

Best regards,
