The fedora-netdev kernels are available here: http://people.redhat.com/linville/kernels/fedora-netdev/ Please give those a try and post the results here...thanks! I've downloaded and installed the netdev kernel and rebooted. The result is
the same, only 10 Mbps/half duplex
[root@fedora-pc ~]# ethtool eth0
Settings for eth0:
Supported ports: [ TP MII ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
Supports auto-negotiation: Yes
Advertised link modes: 10baseT/Half
Advertised auto-negotiation: Yes
Speed: 10Mb/s
Duplex: Half
Port: MII
PHYAD: 24
Transceiver: internal
Auto-negotiation: on
Current message level: 0x00000001 (1)
Link detected: yes
[root@fedora-pc ~]# uname -r
2.6.14-1.1644_FC4.netdev.3
Although changing the settings by hand is posible. I used: ethtool -s eth0
speed 100 duplex half autoneg off
I chose 100 Mbps half duplex cause the system is connected to autosensing
switch, hardcoding to 100 full duplex would lead to duplex mismatch.
It still seems like the interface is limited to 10 Mbps/half duplex. It takes
15 minutes to copy a 700MB file.
Possible solution.
I have managed to get the interface working at 100 Mbps/ full duplex
(autonegotiated). I had to download the 3c90xcfg program of the 3com website.
Booted the Dell 8100 of an old DOS 6.22 disk and used the 3c90xcfg program to
show the bootrom settings. I noticed that the bootrom settings were limited
to 10 Mbps / half duplex. Using the same tool i was able to activate auto-
negotiation and i rebooted fedora core 4.
Now the performance is a lot better. copying the same 700MB file takes appr 4
minutes. Ethtool displayes now:
[root@fedora-pc ~]# ethtool eth0
Settings for eth0:
Supported ports: [ TP MII ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full

That certainly seems to have corrected the issue. Since this appears to have been a hardware setup issue, I'm going to close this as NOTABUG. Thanks for reporting the resolution! Any chance you could post the URL for the 3c90xcfg program??? Thanks, Jeff G. The 3c90xcfg program can be found on the 3com site (www.3com.com). Search for the driver of the 3c905c. You wil find 2 driverdisks (3c90x1.exe and 3c90x2.exe. Extract the second disk and in a subdir (i think diag) the 3c90xcfg.exe file can be found. There are two more files staring with 3c90xcfg, i dont know if they are needed, but i copied all three files to a DOS disk and used this disk to adjust the settings of my "onboard" 3c905cc tornado ethernet NIC.

Description of problem: When transfering lots of data, i noticed a slow performance. I was expecting to use autonegotiated 100BaseTX (100 Mbps/full duplex). Investigation showed that the driver was using 10BaseT half duplex. See: [root@fedora-pc ~]# ethtool eth0 Settings for eth0: Supported ports: [ TP MII ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half Advertised auto-negotiation: Yes Speed: 10Mb/s Duplex: Half Port: MII PHYAD: 24 Transceiver: internal Auto-negotiation: on Current message level: 0x00000001 (1) Link detected: yes I noticed that the only atvertised link mode is 10 Mbps/ half duplex and not all the modes its capable off. Version-Release number of selected component (if applicable): Here some additional information. I,m using a Dell Dimension 8100 system with build in Network adapter. It's using Fedora Core 4 with all the released updates. Now some output [root@fedora-pc ~]# lspci -v 02:0c.0 Ethernet controller: 3Com Corporation 3c905C-TX/TX-M [Tornado] (rev 78) Subsystem: Dell: Unknown device 00c7 Flags: bus master, medium devsel, latency 64, IRQ 3 I/O ports at ec00 [size=128] Memory at ff1fdc00 (32-bit, non-prefetchable) [size=128] Expansion ROM at 40000000 [disabled] [size=128K] Capabilities: [dc] Power Management version 2 [root@fedora-pc ~]# cat /etc/modprobe.conf alias eth0 3c59x alias eth1 hisax alias snd-card-0 snd-emu10k1 options snd-card-0 index=0 options snd-emu10k1 index=0 remove snd-emu10k1 { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-emu10k1 alias usb-controller uhci-hcd [root@fedora-pc ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0 BOOTPROTO=static BROADCAST=192.168.1.255 HWADDR=00:B0:D0:BE:3A:D7 IPADDR=192.168.1.10 NETMASK=255.255.255.0 NETWORK=192.168.1.0 ONBOOT=yes TYPE=Ethernet How reproducible: Alwas Steps to Reproduce: 1. reboot 2. ifdonw eth0 3. ifup eth0 Actual results: Expected results: to connect with 100 Mbps\full duplex Additional info:
