Re: rsync over ssh, slow speed (700 kB/s) on x230

Hi,

over cable/lan everything is fine.
On my router (OpenWRT) I detected a speed/bandwidth drop from 72 Mbit/s
down to 6 Mbit/s when I start the copy over wireless. That's strange,
because under Linux I don't see this issue.
Lesson learned: use the cable :)

Best regards,
Sven
