saygoodie welcome to the forum.
it depends on what plan your have 4,6 or 8mbps. thats any were from 488kb/s to 976kb/s. You should be getting those speeds right away, but its probally just because your connection is not tweaked correctly, clear your cache and do this test http://www.testmy.net/tools/test/d_load.php?step1_timed=&step1_size=&step1_validation=&testall=&s=12160&st=st&ni=ni&ta=&top=&tt=1&nobar= then post the results.
You can use tcp optimazer for tweaking to start with. you can get it here http://www.testmy.net/forum/t-11975
