Last weekend I had to resort to getting a Vodafone USB Sim card modem for my desktop because Italia Telecom are too damn lazy to install a landline to my house.

Anyway, I am getting very poor reception and download/upload speeds and was wondering if there was a way of improving matters.

I have put the Sim card in my cell phone to find the best spot and that is by the window in an upstairs bedroom, which is totally impractical. At the moment I have had to wheel the computer to the opposite side of the living room to get at least some reception.

Is there some sort of box or antenna I can mount outside on the roof or some sort of Heath Robinson contraption I can build to improve preformance?

One other problem is that the USB cable that came with it is only about 50cm but when I plug it into my 1.75m cable it does not work even though the cable is fine. So not very flexible.

Thanks.

There can be something disturbs a signal? This can check. You can try to make the external aerial from a copper wire. I was helped by five metre wire, 1.5 radius

How do I attach a copper wire to this:

To begin with, it is necessary to open case to find the aerial
if you can.
ps: Tell me modem mark

What is the 'modem mark'?

I wish to tell "model" as, MD950, E272, "GSM/GPRS/EDGE modem Vodafone MD950".

Its a Huawei K3715 HSPA USB Stick.

I think you need to add aerial or change modem model. out of home, on street a signal bad?

It is connected to my desktop computer.

Could you suggest a better modem?

Would this help?:
