I'm not sure what standard is 108mbps. 802.11b is 11mbps and 802.11g is 54mbps but maybe super G is 108 mbps. You can have a 108mbps network, but the most you'll get off you cable modem is 5mpbs down and maybe 500kbps up. So your internet is actually whatever you are getting from your cable/dsl modem but your local network can be as fast as therouter says it is.
