I just wanted to bring to your attention a very nice router
The 3G dongle is plugged right in, and the PC connects via ethernet
Wifi is a bonus
Stabilized 12V 1A power requirement.
About 340SEK (webhallen) or 35€ is very affordable.
With it I did not need the 3G device driver or other sw on the PC anymore which makes the boot faster.
Wifi is a nice little extra.
As well as 3 ethernet ports.
I supply the power from the PC PSU
