I think the 10Mbps is the LAN connection if you have 1 Mbps connection it would say 1Mbps when you hovered the mouse over it,is the BB icon not showing on the taskbar? If not open the network connections folder,right click the BB connection,select properties and tick the box show icon when connected at the bottom of the box,then hover your mouse over it in the task bar it should say 1Mbps.
The upload speed of any Broadband connection, be it Dial-up, ADSL or Cable, is always significatly less than the upload speed, this is due to the way the lines work.
With dial-up the uplink was normally 33k whilst the down-link was 56k.
With most ADSL lines the uplink is 128Kb whilst the downlink is 512, 1152 or 2304Kb.
ADSL stands for Asynchronous Digital Subscriber Line, Asynchronous means not synchronised, ie different speeds.
Normally people download much more than they upload, so this isn't a problem.
If you want the same speed in both directions then you need an SDSL line, these are for businesses that run their own web servers, and this is reflected in the scary prices commanded for SDSL lines. click here
