## Description

desertcart.com: Sunydog 4W 4000mW 802.11b/g/n WiFi Wireless Amplifier Router 2.4Ghz WLAN ZigBee BT Signal Booster with Antenna TDD : Electronics

Review: Does exactly as advertised. Worth it. - Ordered two of these to boost WiFi signal on a recording unit for a camera system. The recording unit had two internal antennas. I disconnected the internal antennas, popped a couple holes in the housing to allow replacement antennas to be hooked up to the units board, installed these amps between the unit and external antenna. The recording unit is in my basement, in a fully enclosed steel rack). The WiFi signal strength on the outdoor camera the furthest away went from an unreliable and choppy 26% strength all the way up to 80%, which allowed for its UHD video quality and responsive control of the camera again. Absolutely, 100% worth the money and did as advertised. All plug and play, absolutely zero configuration or setup beyond hooking up cables.
Review: Good when it works, but poor durability... - The antenna worked several months and then it suddenly stopped broadcasting a signal. I bought another antenna thinking mine might have been defective, but the other one also only lasted for several months. This is such a disappointment that these things aren't made with durability in mind, because while they were working I was able to resolve all the issues I had with a Bluetooth Transmitter, and could get reception to it from almost any room in the house.

### ⭐⭐⭐⭐⭐ Looks to be great build quality
*by A***R on July 7, 2025*

Figured it would just be a small booster chip inside but I was wrong. I have not tested it yet but I'm assuming it will work great. I will return once I have tested
