The Dodocool DC39 is an older single-band Wi-Fi repeater/access point, not a Bluetooth device. Reviews describe 2.4 GHz 802.11b/g/n support, an advertised rate of up to 300 Mbps, and a 100-meter range claim. Those figures are specifications and review claims—not measured results or a promise of usable coverage in your home. The available information also does not establish a current price or whether the DC39 is still for sale, so “excellent price” is historical framing rather than a present-day recommendation.

What the Dodocool DC39 is

The FCC record identifies FCC ID 2AHDI-DC39 as a Wireless N AP/Repeater associated with Shenzhen TOMTOP Technology Co., Ltd. The record lists operation from 2.412 to 2.462 GHz and an authorization date of January 5, 2017. That confirms the device category and filing details; it is not an independent performance review.

The DC39 is intended to extend or provide Wi-Fi, rather than serve as an audio accessory. The model name matters: unrelated products use the similar name “D39,” so check that a listing explicitly identifies the DC39 Wi-Fi repeater.

DC39 specifications and what they do—and do not—tell you

Item What older reviews report How to interpret it
Wi-Fi band 2.4 GHz; the FCC record covers 2.412–2.462 GHz. It is not described as dual-band. It cannot extend a 5 GHz-only network using that band.
Wireless standard 802.11b/g/n. This is an older Wireless-N device specification.
Advertised link rate Up to 300 Mbps. This is not a measured internet speed or a guarantee of throughput to a connected device.
Range A rated distance or coverage claim of up to 100 meters. The reviews do not specify testing conditions or provide independent measurements. Walls, interference, placement, and the router all affect real coverage.
Modes and wired connection Reviews report repeater and access-point modes, plus an Ethernet port. The port speed and package contents are not established by the available specifications.

The 300 Mbps and 100-meter figures come from the product descriptions and older reviews, including Mi Mundo Gadget’s 2017 review and WirelesSHack’s June 5, 2019 review. They should be treated as published claims, not as results demonstrated in a particular home.

Could the DC39 fill a Wi-Fi coverage gap?

It may suit a basic setup that needs 2.4 GHz Wi-Fi extended and whose router and client devices support compatible standards. Repeater placement is crucial: the device needs a usable connection to the router where it is installed, otherwise it has little signal to relay. A range figure alone cannot tell you whether it will cover a specific room or deliver a particular speed.

The reported access-point mode may be useful when you can connect the device to the router over Ethernet and want it to provide Wi-Fi nearby. Confirm the mode and port details against the exact unit or its manual before relying on that setup; the reviews do not establish port speed.

Is its price still attractive?

Older coverage described the DC39 as inexpensive, but the available sources do not establish a current price, active listing, or present-day value comparison. Treat “excellent price” as a historical review judgment, not evidence that the DC39 is currently available or a good buy. If you find one for sale, compare its price and condition with currently available extenders, and verify that the listing is for the DC39 rather than a similarly named product.

How to compare it with a newer extender

Start with the bands your router uses and the area you need to reach. Then compare supported bands, advertised link rates, wired Ethernet and access-point support, and whether the exact model is currently available. Specifications can narrow the options, but they do not prove how well a device will perform in your home.

For a category reference, TP-Link’s RE300 manufacturer page lists dual-band support, with up to 300 Mbps on 2.4 GHz and up to 867 Mbps on 5 GHz. That is a specification comparison only; it is not a performance verdict against the DC39.
