Samba Share Problem

Hi Guy;

I use samba for windows share, I found client in same sub network,it's RW speed about 80-100mbps, But when I change the client to different sub network env, it's RW speed is only half of before, do you meet same issue? how to deal?
That sounds like the router that's between the subnets might be the cause.
Yes, but there's something that routes the traffic between the subnets. Subnets don't magically start talking to each other.
