There are some references on the OpenWrt website, about people getting a 4G USB dongle working with an OpenWrt router, not running OpenWrt directly on it. We can see the Vendor ID is 05C6, the product ID is F000. sr 2 : 0 : 0 : 0 : Attached scsi generic sg2 type 5 sr 2:0:0:0: Attached scsi generic sg2 type 5

The memory chip should be SK Hynix H8ACS0PE0MBR-46M. It’s a Qualcomm design, but the markings for the main chip are all but gone.

We can remove it to reveal all components, besides the Qualcomm RTR8605 RF Transceiver. There’s a sticky metal sheet on top that should act as a shield. We just need to remove three screws before popping up the two plastic shells. Let’s open the device to check out the design and main components. The MAC address prefix (381C23) reveals the manufacturer should be Hilan Technology CO.,LTD, a company based in Shenzhen, China. The bottom cover has credential information for the WiFi access point (SSID: 4G-UFI-XX, password: 1234567890) and the web interface used for configuration( username: admin, password: admin). The USB dongle ships with a user manual in English mainly explaining how to install the driver when connecting it to a Windows 10 computer. That’s perfectly fine for my use case, as the plan is to use it as a standalone WiFi hotspot with an unlimited 10 Mbps SIM card, and in locations with low population densities so 5GHz WiFi is not a must. SpecificationsĤG performance is limited to 150Mbps DL, 50Mbps UL, while WiFi only supports up to 72 Mbps using 802.11n 2.4GHz WiFi. It’s a 3-in-1 device that works as a 4G USB dongle connected to a PC or laptop, a 4G USB WiFi cellular router/hotspot, and a USB flash drive when adding a MicroSD card. I’ve purchased a USB dongle acting as a WiFI & 4G cellular router with a generic name “4G LTE WiFi Modem” and listed as “4G LTE WiFi Hotspot Wireless Router USB Dongle 150Mbps Modem Stick Sim Card” on the online store (Lazada) I bought it from.
