Providers list their connection speeds in bits/s instead of in bytes/s. Most programs (including aMule), however, want you to enter speeds in (kilo-) bytes per second.
Since 8 bit equals 1 byte your connection speeds are:
- Download (réception) = 1920 kb/s
- Upload (envoi) = 64 kb/s
In aMule, I would set the download limit to something like 1000 kb/s (this does not really matter that much, because you usually don't get speeds faster than 200k/s anyway) and the upload speed to 56 kb/s.
