Doubt its computer emissions that are causing a problem, more the modem
is less screened by the building "clutter" and the losses on a USB lead
are far far less than a lump of co-ax at the frequencies involved;!...

I got my information from the Vodafone site which now says 30 days.

... or even a long one. All the dongles I've tried work well on the
end of a 10m cable - long enough to dangle the dongle from the
curtain rail, in the window.

I tried a USB 3g dongle on the end of a cheap 3 meter USB
extension lead and it stopped working.

So quality and length of the lead is important

Yup, my ZTE MF627 doesn't work on the end of a cheap 5m USB cable. The
light doesn't even come on. The same cable also doesn't work when I plug a
card reader into it, but does for a USB stick.

Since the MF627 gets a bit warm in use, my guess is the resistance along
the cable is such that it can't provide enough current to the device without
a big voltage drop. So the devices aren't getting enough power.

It might be feasible to run another cable in parallel to provide more
current, but I haven't tried this.
