Covering of 3G networks today not always ideal, especially in areas, remote from the big city centers. There are ways to improve speed 3G of the USB modem and to optimize its work in the conditions of a poor signal.
Setup of port
Oddly enough, but correct setup of port can improve quality of processing of a signal 3G almost twice. For a start check the speed of port of data reception arriving from the Internet. For this purpose open "Device manager" in the Equipment tab of the section "My Computer". In a tab "Ports" select the Serial port item. The right click opens a possibility of access to "Parameters of port" through the Properties menu. In "Parameters of port" it is necessary to raise a modem throughput threshold from set by default 9600bit/with to 115200bit/page. Thus, settings of port are not a barrier to increase in speed up to the upper limits any more.
Setup of throughput of the channel
For setup of throughput of the channel it is necessary to lift the limits set by default in the Computer Configurations menu. For this purpose in "The manager of packages" of point "Network" of the section "Administrative Templates" make doubleclick on the Limit Throughput command. Then open the Parameter tab and check "Is included", and in the Restriction of Throughput window replace "20" with "0". Confirm application of settings and click Apprx. Restriction of throughput of the channel are removed.
Setup of the modem
After carrying out all settings of the computer it is necessary to configure directly 3G the USB modem. If the modem is equipped with the connector for connection external 3G antennas, then it is useful to use it. However if the modem formally shows consistent reception ("all strips" are visible), and speed at the same time unsatisfactory, then the antenna will hardly help. In that case, most likely, the notice of users in network is the reason of low speed. Repeater throughput just is not enough for all. It is easy to check this assumption at night when the number of persons interested "sit" on the Internet decreases. If strips "not all" - can help the USB extender. The fact is that any computer is an interfering source. Besides the human body capacity and also capacity of the objects which are near the computer and the modem can seriously weaken the signal caught by the modem antenna.
Shnur with the USB connector allows to transfer the modem to a zone of more consistent reception, far away from interfering sources. The recommended length of such cable should not exceed 3 meters. It is not recommended to use cables less than 1.5 meters long also in view of their inefficiency. Connect the modem via the USB extender to the computer. It usually considerably increases communication quality.
