The Dodocool DC39 is an older, single-band 2.4 GHz Wi-Fi repeater and access point. Reviews advertised a 300 Mbps link rate and a 100-meter range, but those figures are not verified real-world performance, and the available sources do not establish a current price or whether the model is still for sale.
What is the Dodocool DC39?
The FCC record identifies model DC39 as a Wireless N access point/repeater associated with Shenzhen TOMTOP Technology Co., Ltd. Its filing was authorized on January 5, 2017, for operation in the 2.412–2.462 GHz band. FCC ID 2AHDI-DC39 record

That makes the DC39 a Wi-Fi networking device, not a Bluetooth headset. The similar “D39” name also appears on unrelated audio products, so the exact DC39 model designation matters.

| Feature | What published sources report | What that does—and does not—tell you |
|---|---|---|
| Wi-Fi band | 2.4 GHz; the FCC record covers 2.412–2.462 GHz. FCC record; Mi Mundo Gadget; WirelesSHack | It is not described as a dual-band extender. The sources do not establish the coverage or speed you will get in a particular home. |
| Wireless standard and advertised rate | Reviews list 802.11b/g/n and up to 300 Mbps. Mi Mundo Gadget; WirelesSHack | “Up to 300 Mbps” is a published link-rate specification, not a promise of 300 Mbps internet throughput. |
| Range | Reviews report a 100-meter rated distance or coverage claim. Mi Mundo Gadget; WirelesSHack | The sources provide no test conditions or independent measurements, so this is not a guarantee of usable range in a home. |
| Operating modes and Ethernet | Reviews report repeater and access-point modes, plus an Ethernet port. Mi Mundo Gadget; WirelesSHack | The port speed and exact package contents are not established by these sources. |
The 100-meter claim should be treated particularly cautiously: distance figures do not account for walls, interference, router placement, or other conditions that affect a real connection.

Could it fill a Wi-Fi coverage gap?
Its reported repeater mode is intended to extend an existing Wi-Fi network; its reported access-point mode provides another way to use the device. Whether either mode suits your setup depends on your router, the location of the weak-coverage area, and how you can connect the equipment. The available specifications do not demonstrate that the DC39 will improve coverage in a particular home.
Before choosing any extender, check the router’s supported bands and the area you want to cover. Compare the extender’s bands, advertised rates, Ethernet availability, access-point mode, and current availability. These are useful specification checks, not substitutes for real-world performance testing.

Is the “excellent price” claim still relevant?
The title’s price framing comes from older coverage: a 2017 review described the DC39 as inexpensive, while a 2019 review also covered the model. Mi Mundo Gadget; WirelesSHack Those sources do not establish a current sale price, active listing, or present-day value. Treat the affordability claim as historical rather than a reason to buy now.

Verdict
The DC39’s published profile is straightforward: a 2.4 GHz 802.11b/g/n repeater/access point with a reported Ethernet port, an advertised rate of up to 300 Mbps, and a review-listed 100-meter range claim. It may be relevant if you are examining this specific older model, but the evidence does not verify its actual performance, present availability, or current value. For a purchase decision, compare currently available devices against your router’s bands and your coverage needs rather than relying on the DC39’s historical price or range language.
