I had to replace a disk (the one with all of the home directories on it) on an FC3 box, and so I bought a new drive (particulars unimportant).
To make a long story short, I decided to put FC4 on this box, and so I installed the new drive and put the root filesystem on it. I still have the old FC3 root drive and can boot to either for comparison...
Under FC3, I have no network problems that I can detect; however, under FC4 there are two distinct (related? no idea) problems which have eluded me. I have tried looking up both of these in the archives, but have had no luck (some similar issues, but nothing exactly like either of these unless I missed them).
Problem 1: network card goes to sleep.
This machine has 2 network cards, both on-board. The 1GB card L(Intel 82540EM) goes to the smartswitch to tolk to the local network, and does not show any problems. The other card (nVidia nForce2) is a 100MB card and talks to the DSL modem. Periodically I cannot connect to the internet at all - or even ping the DSL modem. This happens irregularly but about 5-10 times/day. If I reboot back to FC3, the problem does not occur. Network configurations between the two (FC3/FC4) are as identical as I can make them. The first few times the problem occurs, sometimes retarting networking works, but eventually a full sys reboot is the only thing which works.
Problem 2: slow local network.
Under FC3 throughput on the LOCAL network (1GB lan) is very fast. Under FC4, the best I have seen is ONE transfer of about 1.2 MB/s - and throughput drops to as low as 50-75KB/s at times. Again, this does not occur under FC3 but does under FC4. Again the same setup as nearly as I can make it. No workaround found so far.
Any suggestions would be greatly appreciated.

Anything relevant in the syslog?

First question: are you using Nvidia proprietary drivers? Were you? Are they from somewhere like livna, or did you download direct from Nvidia?
Do a /sbin/lsmod | grep forcedeth if you're not sure.
(Likewise, it might be a good idea to check that your /etc/modprobe.conf files have the right aliases for eth0 and eth1).
Second question: I note you say that the Intel card occasionally connects at 100 Mbit/s. Do you get *any* improvements at that speed? At 10 Mbit/s? You can use the ethtool utility to change this.
Make sure that you've got the same duplex settings.
Third question: are you up to date with FC4 updates? Were you up to date with FC3 updates?
One other point: it looks like you're reading the digest. If you do that, please be careful to replace the Subject: header with the original one, so that we've got a chance of keeping your e-mails together. You may find that the MIME version of the digest is more useful.
Use the link at the bottom of each e-mail to change your preferences.
Hope this helps,
James.

Question is asked in Feb 2006 ...!!!!!!!!!! :-)
Dear Mr. William
please check the date of you computer

Which would have been the correct timeframe for moving an FC3 system to FC4. At that time FC5 was the new release. I know, I had a system which had to jump from FC3 to FC5 after FC3 hit EOL.

Stranger things have happened. Perhaps it was lost in a machine that has only recently been rebooted....and its sendmail queue finally got flushed?

Sorry if this sounds glib, but the suggestion that comes to mind is "install F12". FC3 and FC4 are ancient systems, long past their shelflife and completely unsupported (including for security updates).
