Despite the convenience and versatility of USB modems, the disadvantages of wireless communication remain the same: a drop in the signal level sometimes occurs even in large cities, not to mention areas where there are much fewer towers.
Instructions
Step 1
Check if anything is blocking the modem signal. It is possible that the quality of the connection deteriorates because the modem is, for example, in a computer case near a wall. In this case, use the USB connectors on the front panel of the system unit, if such are provided by the model of the computer case, or purchase a special extension cable and install the modem in a place where the signal will be better received.
Step 2
If you are using a laptop or netbook, make sure that the signal is not obstructed by other objects or your hand. When using a wireless mouse or Bluetooth connection in your computer with the modem at the same time, make sure that signals do not interfere with each other. If possible for your computer model, place these devices in ports on opposite sides of the chassis. The same is true for a computer that has multiple active wireless device connections at the same time.
Step 3
If you are away from home, and the signal received by the USB modem has become worse, change your location so that the quality of communication becomes better (usually closer to the MTS towers). Also, the signal quality will be poor when using a USB modem in basements and highly isolated rooms.
Step 4
Check if the drop in speed is a malfunction of your modem. If your phone has a 3G function, check the MTS signal strength at your location. Also check if the slow speed of loading web pages is the result of slow browser operation by opening any other browser and see if the speed changes.
Step 5
Check the load of system resources in the task manager, it is possible that Internet problems are caused by a lack of RAM or processor frequency to perform the necessary operations.
