Wireless MAG

Are there any MAG boxes that are good with a wireless connection?

I'm looking for a 2nd box and would prefer it to be wireless instead of having to route a 10 meter lan cable from the living to the upstairs bedroom and then through to the next bedroom

Thanks

I have a MAG256Wi, the 'Wi' denoting it's for wifi as well as for use with ethernet hard wiring - but as always it depends in what level of internet connection you have to use it with.
I have a fairly constant 60mbps download speed and thus get good wifi connection via my MAG256Wi.
However it's not really relevant now as this model is now obsolete - although may be available on fleabay etc?
