My LAN connection seems to be running at half-duplex!

[RIgnazio]

Help please! My LAN connection appears to be running at half-duplex. I am running FC3, and I have a CAT6 cable that connects my box to my router. My dad's comp (Windows 98 :( ) Is very fast with the DSL connection I have, but my computer takes forever, and my downloads always just stop.

Please help.

use ethtool to query the nic

ethtool -h

[RIgnazio]

I'm at school right now so I obviously can't, but what good would that do me? I will try ethtool -h when i get home, but should that tell me if it is running at half-duplex, and why?

i just can't figure it out. I will reset my router and then run the tool.

ANYONE! with suggestions, please help.

It seems to be something wrong somewheres, because during a download, it will stop right around 100mb downloaded, and cancel...disconnect from the server and all, but I don't appear to have this problem with gaim.

OK. I reset my router, and I am about to download a large file to test...now, the only problem is that the ethtool does not work.


[root@R3-DESKTOP ~]# ethtool -s eth0 duplex full
Cannot get current device settings: Operation not supported
not setting duplex
[root@R3-DESKTOP ~]#


HELP!

OK. I ran ethereal, and captured my packets. My router is trying to probe all IP's which is making a lot of my packets to collide. If any of you know about routers...

mii-tool is an alternative to ethtool. To get the current state of your NIC:mii-tool eth0
Force 100baseT Full Duplex:mii-tool -F 100baseTx-FD eth0
Force 10baseT Full Duplex:mii-tool -F 10baseT-FD eth0

[root@R3-DESKTOP ~]# mii-tool eth0
SIOCGMIIPHY on 'eth0' failed: Bad address
[root@R3-DESKTOP ~]# mii-tool -F 100baseTx-FD eth0
SIOCGMIIPHY on 'eth0' failed: Bad address
[root@R3-DESKTOP ~]#

It would appear to have a bit of a problem with the query :(
