I have 2 3G usb modems. 1 is ZTE and the other one is Huawei, both use a same ISP at same place. But the problem is that Huawei's device gets 3 signals while ZTE's device seldom get a single signal. Someone told me there's a chip inside the usb modems which become weaker after a year or so, and the reception gets weaker. I want to know the reason and the possible solution.

Newer devices often have multiple antennas inside using them for antenna diversity. This can significantly increase the signal quality.
