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.
The only solution I have even known with such an issue is to either make a warranty claim (depends on whether its still within it) or sadly put up with it. Then again, technology standards have come a long way in the past few years, so this may not necessarly be the case with some newer, more expensive brands.
