How to connect multiple USB devices to one USB port on a Keenetic
If you plan to connect several USB devices to your router simultaneously (these can be storage devices, modems, printers and various combinations of them), then the preferred option is to use a Keenetic model with two USB ports to connect devices directly to the router.
But if you have already purchased Keenetic with one USB port and you need to connect several devices, you can use a USB hub with its own power supply. This device is also called an active hub or a hub with an external power supply. If you use a passive hub (without an external adapter), the power on the router's USB port may not be enough to properly work with two devices because the power on one USB port (2.0 or 3.0) of Keenetic is limited to 1A.
Important
In the current Keenetic models, the voltage at the USB port has been raised to 5.2V and the current at the USB 2.0 port is now the same as the standard USB 3.0, and smoothing capacitances have been installed.
Keep in mind that the USB device may draw significantly more power if used intensively. It is recommended to use a hub whose power adapter supports at least 2 Amps.
Important
When a 3G/4G USB modem is connected to the Keenetic router via a USB hub, the automatic USB modem power reset function may not work on the router. When triggered, it will disable not only the USB modem but also other USB devices, because they are connected to the same USB port on the router.
Tip
A limitation is connecting two identical models of USB modems and USB printers to the router at the same time, as in this situation two identical IDs of the devices to be connected will appear in the system and the router operating system will not be able to work with them correctly. Thus, two identical models of modems and printers cannot be connected to the router. If the models to be connected are different, their IDs will be different, and there will be no problems in operation.
