Today, 3G coverage is not always ideal, especially in areas remote from large urban centers. There are ways to improve the speed of your 3G USB dongle and optimize its performance in weak signal conditions.
Port setting
Oddly enough, but the correct port setting can improve the quality of 3G signal processing by almost half. First, check the speed of the port for receiving data from the Internet. To do this, open the "Device Manager" in the "Hardware" tab of the "My Computer" section. In the "Ports" tab, select the "Serial Port" item. A right click opens the ability to access the "Port Parameters" through the "Properties" menu. In the "Port parameters" you need to increase the modem bandwidth threshold from the default 9600bps to 115200bps. Thus, port settings are no longer a barrier to higher speeds.
Channel bandwidth setting
To configure the bandwidth of the channel, you must remove the restrictions set by default in the "Computer configuration" menu. To do this, in the "Package Manager" of the "Network" item of the "Administrative Templates" section, double-click on the "Limit Bandwidth" command. Then open the "Parameter" tab and check the "Enabled" box, and in the "Bandwidth Limit" window change "20" to "0". Confirm the application of the settings and click OK. Channel bandwidth restrictions have been removed.
Modem configuration
After completing all the computer settings, you need to configure the 3G USB modem directly. If the modem is equipped with a connector for connecting an external 3G antenna, then it is useful to use this. However, if the modem formally demonstrates reliable reception ("all stripes" are visible), and the speed is unsatisfactory, then the antenna is unlikely to help. The reason for the low speed in this case, most likely, is the sold-out of users on the network. The repeater bandwidth is simply not enough for everyone. This assumption can be easily verified at night, when the number of people wishing to "surf" the Internet decreases. In the event that the strips are "not all" - a USB extension cable can help. The fact is that any computer is a source of interference. In addition, the capacity of the human body, as well as the capacity of objects near the computer and the modem, can seriously weaken the signal picked up by the antenna of the modem.
A USB cable allows you to move the modem to an area of better reception, away from sources of interference. The recommended length of such a cable should not exceed 3 meters. It is also not recommended to use cables less than 1.5 meters in length due to their inefficiency. Connect the modem via a USB extension cable to your computer. This usually significantly improves the quality of the connection.
