I'm using a SiS 10/100 Ethernet integrated on a motherboard I have a problem with network speeds.
I'm using Debian stable right now and that is when the problem started. I had Fedroa core 1 installed and my speeds were good. But with Debian I have slow network speeds. A 40MB file takes about 4 minutes to transfer and it should only take about 40 seconds or so, which is what the speeds were with Fedora and between and windows computers on the network. Could this be Debian needs a new driver for the nic to make it work faster? Or some other setting?
mii-tool tells me eth0: negotiated 100baseTx-FD, link ok. So the card is up and running correctly, so it seems. But between the debian computer and any other computers the speeds seem to be very slow. A 1 GB file gives me estimated times of 120 minutes or more and before a 1 GB file would transfer in about 15 minutes. There is no change in hardware, just switched from fedora to debian. Debian is running much less in the backround and the computer does run faster with it but the network speeds have dropped with it. I'm running ftpd, httpd, sshd and samba. Nothing else, where fedora had a ton of stuff running on it but the network speeds were up.
This isn't just with samba shares either. If I ftp on the local network the speeds are only about 170k/s, where they used to be 4000-6000k/s on the lan. Is there some setting that may be limiting the lan speeds?

Any suggestions on how to get my full network speed back with Debian? I like Debian better and don't want to go back to fedora. I'm going to try Debian testing and see if that may do it. Newer kernal and drivers may do the trick, but any suggestions would help in case I have the same problem with testing as I do with stable.
I'm sure it is a 100 meg switch. With other distro of linux I get the 100/FD speed, and even with win2000 I get the 100/FD speed. Just since I installed Debian has it slowed down and only with transfer to and from the debian machine. The other computers still have the 100/FD speed. The switch has 3 lights on it for status. Link/Act, Full/Col, 100. All 3 lights are lit for all the computers on the network meaning that they have have link at full duplex 100mbps.
