If you are experiencing SLOW network access, it could be due to the fact
that you are running IPv6.
An easy way to disable this is to modify /etc/modprobe.conf to include
the following line:
alias net-pf-10 off
You will need to reboot, but it solved the problem for me. I have
Comcast cable Internet, and prior to upgrade to FC2, I was seeing >
3Mb/s download rates. After the upgrade to FC2, I was seeing around
1.2Mb/s download rates. Obviously, this was unacceptable.
Turns out IPv6 was enabled in my configuration and the added line to the
modprobe.conf file fixed my network speed issues. By disabling IPv6, I
was able to get back to what I expected to be the true bandwidth.
Hopefully this note will help othere who may experience the same problems.
Regards.
