because of pppoe overhead.See http://pflog.net/dsl_overhead/
I have at&t DSL, and I'm paying for 3mbps download and 512kbps upload. Ever since I turned off my modem yesterday, and turned it back on to fix a connection issue, My connection page only says I have 2496 Kbps for download speed. There is a sticker on my modem that says to leave modem on for 10 days to maximize speed. Is this the problem, or is there something else I can do?
