I am considering getting mobile broadband as my main home broadband connection as I cannot get any other forms of broadband.

I was wanting to know if anybody knows of a good 3G router that I can plug a USB modem into or at least put the sim into the router and attach an external antenna to. preferably i would like one that the USB modem plugs into.

I need one that has at least on ethernet port on it to plug my desktop into and it to also be a wifi connection so I can run my 2 laptops from it.

Does anybody know of particularly good models for this that have good wifi signal and are very reliable and efficient.

Also does anybody know if using a 3G router will cause any of the bandwith speed to decrease?

Thanks - all replies appreciated
