But, Yes, you will have faster download/upload..
Look at it as a fire hydrant connected to smaller hose (like your garden hose).. and your home water tap, and see the time it takes to fill your bathtub... I'm sure that you fill the bathtub faster by using the fire hydrant connection.
and yes, possibly faster printing too... (with faster connection, you will empty the printer spooler/memory faster, translate to faster output.)
Do I really need these 108 Mbps or 240Mbps MIMO or not wireless routers? If I was to have a laptop with a 54Mbps a/g card and a 4Mbps cable connection does it really make a difference between the 54 or the 240 Mbps? And what if I had a print server set up built in the router? would there be a difference then?
