My on-board LAN refused to connect to the ethernet (same in F8 and F9 which is why I stayed with F7). As I needed some features of OOo3 and FF3 I upgraded to F10 anyhow. This is on an older MSI Neon MB, Athlon64.
The way I can get LAN to work is with the good old terminal!
su
rmmod r8169
modprobe r8169
service network start

Since the latest update naturally something else is broken but that's less of a problem. Now SELinux blocks an "attack" of Networkmanager and DHCP which is just what I was used to (Networkmanager) from an update in F8.
Looks to me like the Fdora crew is under tremendous pressure to release as fast as possible

Guess I have to go to bugzilla now....

update:
After far to many hours over the long Thanksgiving weekend I did what I should have done long ago: bare metal install of CentOS5. EOL 2011 and EOS of 2014, that's just what I need for my use. Took me a while to figure out what I want from an OS.

I am having some problems with Fedora 10 also, No WiFi BUT is worked on the beta releases !!!
CentOS & my graphics do not agree, all I have is lines on my LCD ???

I'm really happy with CentOS5.2! As I am not paranoid I also install packages which are not approved (in the repository) and so far nothing broke (yet) and if it does the standard sentence in the CentOS forum applies: I am lucky, I can still keep both pieces....... And the nice thing is that there are a lot of bits compiled for RHEL5.2!

What graphics card do you have??? I have an old nvidia MX440 and the nv driver works just fine. In the office we have SUN Opterons's with one of the high end nvidias and they cause problems with the supplied drivers and even worse with the ones from nvidia. However, if we just install in Vesa mode and then switch to nv they work just fine. Installation doesn't look that nice but you only have to go through once.....
