HeroBox limited to 100Mb ethernet

I’ve recently purchased the new HeroBox and it is surprisingly snappy. However, I’ve had difficulty with both wired and wireless networking running very slow. No matter what I’ve tried the network adapter is limited to 100Mb instead of 1000Mb and I have very poor wireless throughput on both 2.4 and 5Ghz networks. Wired I’ve tried a number of cables, switches, hubs and routers, all cat6 cables and 1Gb - 10Gb network gear with no effect. Wireless I max out at about 60Mbps 1 foot from the router while my cell phone will get 900Mbps.

I have tried different drivers, different bios settings, and a clean installation of Windows with no effect. While the experience of using the box is otherwise great, the slow networking is a deal breaker for my use case. Before I initiated a return is there something else I could try, or is this device really limited to 100Mb ethernet due to some hardware issue?


It is likely that the ethernet port is bad. When testing today I found that the connection is unreliable and now will not stay connected for more than a few seconds. Oddly, in Ubuntu it does register the wired connection as 1000Mb. Connecting the same Cat6 cable to a USB 3 ethernet adapter shows a connection speed of 1Gb and works correctly. As the proper ethernet port is nonfunctional I have initiated a return.

We will process your return as soon as possible. Sorry for the inconvenience

I’ve noticed the same issue with connection speed on two separate units. The connection speed is only showing 100Mb. I connected a usb-c hub with ethernet jack to the front usb-c port and was able to get 1000Mb speeds. It just seems to be the rear ethernet jack. I tried updating the drivers through windows update as well as a fresh install of Windows 10, but no luck so far. The network card shows up as a Realtek PCIe Family Controller, so Windows seems to believe it is capable of 1000Mb speeds. Is there perhaps a driver/firmware issue?

I have received a replacement device, and although the ethernet port is “fully functional,” this device is also limited to 100Mbps in Windows. I had run linux on the previous device and saw that it’s wired speed was reported as 1Gb but I did not actually run any tests. With the replacement device I have found that although rated at 1Gbps the HeroBox is incapable of throughput beyond 100Mbps in Linux indicating this is likely a firmware issue or hardware limitation. I am inclined to believe this is in fact a hardware issue that software will not resolve. Wireless performance on the replacement device is marginally better than the unit it replaced but is massively outperformed by literally every other wireless device I own. This is very disappointing as I really like the box otherwise.

After reading your experience, I just tried installing a copy of Linux Mint in the hopes that maybe I could get 1Gb on that OS, but it was still showing 100Mb while my USB C dongle had no issues showing 1Gb. I agree with you. This seems like a hardware/firmware issue. Perhaps a bios update could fix it? Hopefully Chuwi will get back with us soon with some helpful information.

I hope so as well. I had been planning to use this thing as a replacement for my rpi 4 as a VPN/file server. Being limited to 10% of my network speed on ethernet just kills it. For the time being I will continue using the ethernet adapter but ultimately I’ll likely return this replacement unit unless the advertised gigabit networking speed can be realized.

I have same networking problems. Bought Hero Box based on ChuWi’s claim that WiFi was “1300Mbps on the 5GHz” - Not true - WiFi chip used is 2014 tech and limited to 433 MHz. Likewise, “1 GB LAN” is limited to 100 Mbps. Limitation seems to be due to ChuWi either not wiring up all the pins on the board (GB needs all 4 pairs, 100Mb does not) or not enabling in BIOS. Same RealTek chip with same driver on another brand mini PC has no problem doing GB.
Also had to correct random Network disconnect issues on both the WiFi and wired LAN. This was due to Windows 10 Nov 2019 update changing previous defaults for various Energy Saving features.
Turning the WiFi and Realtek GBE driver energy saving off and also in Windows Power Plan resolved.
No more dropping.

Personally I have had no issues with network dropping out on my replacement device but that is a shame that it likely is a hardware issue for the wired port. I’ve tried multiple drivers/driver settings/bios changes with no luck. What kind of Wi-Fi speeds do you see? For me best case it tops out at around 65Mbps but I am unsure as to what I should expect given the specific hardware, just assumed it should be much faster. Last week I emailed Chuwi aftersale support for clarification on the bogus marketing specs for the HeroBox and received no reply.

If they don’t fix this issue very soon for GB LAN then it’ll be going back for a refund and i won’t be buying any Chuwi products ever again. Pretty pathetic to have a problem like this out of the gate and not be tested.

Can’t definitively say LAN is hardware issue, but my house router & switches are GB throughout. Most rooms were wired with CAT 5e or CAT 6 cabling. All jacks pass on RJ-45 test meter. Hero Box plods along at any jack in house and all other devices get full duplex GB at same locations.

Hero WiFi is out-dated Intel AC-3165 chipset - intro’d in 2014 and Intel’s own spec site says it maxes at 433 Mbps for 5GHz. When 10 ft from my AC-1900 router, it will hit that. Plugging in a USB WiFi dongle with a more recent Realtek chipset gets me 867 Mbps at same distance from router.

I planned to use the Hero Box as a HTPC and A/V storage server for the rest of the house. Streaming a single instance is not an issue, even with the crippled hardware. Transferring a TB+ of files would have taken 2-5 times longer and streaming to 2 or 3 devices at once not pretty.

Currently have both onboard WiFi and LAN networking “disabled” in Windows and am running on USB 3 to GB dongle which gives me full duplex GB and 2-3 times the file transfer speed of the built-in LAN or WiFi.

I also find it very interesting that this thread has been open so long without ANY feedback from ChuWi
