Does USB modem power affect speed?

Question

USB

There is a Huawei E3372 USB modem, which is inserted into the AX-2020P BOX antenna, i.e. the modem is in the box, at a height of 9 meters, a 10 meter cable comes from the antenna, which is inserted into the Keenetic router, the power supply is surprisingly enough. Does it make sense to buy a high-quality USB HUB with additional power and insert it into the router, and it has antennas into the hub cable? Does powering a USB modem affect speed?

Answer 1

10 meter cable

it definitely does.)

Answer 2

As you have already been written - if it does not fall off, then there is enough food. But there is one point: the power may be enough while the modem is working in 3G, and if it switches to 4G, then there may not be enough power. I had a similar story with the same Asus modem and router (Padavan firmware) - when there was 3G, the modem was connected via a 6m cable to a PASSIVE hub, in which there was also a flash drive - everything worked great. And when 4G appeared, the modem began to fall off every 1-5 minutes (as soon as the active data transfer began). I removed the hub and flash drive, left the modem on the 6th extension cord - everything works well. Bottom line: it is possible to take a hub with additional power - take it. But still, it’s better when the modem is directly in the router without extension cords (at such a length, the ping is also lost), and it is the antenna cable that comes from the antenna through the adapter.
