ADSL compressed?
I use a data counter widget to keep track of wifi usage because it's right there on-screen, and can be set to display daily usage and monthly usage from my start-of-month which is the 28th.
There is a BT counter available but I have to log in and then allow for it starting on the first of the month, and being a day or two behind, so I tend not to use it.
But occasionally I check both and it seems that the BT count is up to twenty per cent lighter.
Is there, I wonder, some measure of data compression on ADSL which is unwrapped in the router before entering wifi-space?
