Hi,

So, I have a 3G USB dongle, shitty one, and I found a good spot that has good signal. Though, my USB extension cable is too short. So, simple question.

Does the 3G signal decreases the longer ur extension cable is? If No. Then, check this.
Connecting a external USB Hub to e.x any USB ports on my pc. And then, connect my 3G dongle with an USB extension cable to the USB hub. Would ´that decrease my signal?

I dno if extension cables affects signal :p

It may, it depends on how long you want to go. Back when I started my business, I couldn't afford security cam's, so I used a mismatch of all my webcams and friends webcams. Some times, adding 1 more extension would be the difference between getting a clear picture from the cam and nothing, so it does degrade over distance. How much, you'd have to try.

Yes and No.

An extension cable will not change your 3G reception.
Now usb requires a ack (acknowledgement) from its device, so if the extension cable gets too long without some type of signal rebroadcast device (like a hub) then the voltage in the wire will reduce and degrade the USB communication to the 3g modem.

Since you are using a hub in between you should be just fine.

For future reference, 15-20ft max is about the limitation of usb without a repeater/amplifier.
