you can see that the download speed if diff but the uploadload speed is allways about 730,
so when you do your speed test the upload speed should be the same 730,if its alot lower then 730 i think you might still be on 10 meg,
i think the 10 meg was about 480 up and about 8-9 meg down,
so you could be on the old 10 meg still,and is it running through wireless,
then you may have to look at the cable router settings,the tech guys should be the ones to tell you how to do that,
that the cable modem,
log in with root root
click on operation config and you should have
Network Access : Allowed
Maximum Downstream Data Rate : 20480000
Maximum Upstream Data Rate : 768000
if you are on 20 meg,
