Hey there! I installed Fedora 8 earlier today (so it's a relatively clean install) on a machine dual-booting Vista. Connecting to the wired and wireless networks was a breeze. However, when I use any browser, be it Konquerer, Firefox, or Lynx, I am browsing at ~56k speeds. I have disabled IPv6, and edited my /etc/modprobe.conf and /etc/sysctl.conf files. Nothing seems to be working.
Any help would be greatly appreciated. I don't want to go back to Windows!

IPV6 really never (or almost never) causes any problems. I bunch of gumbies don't understand so they tell everyone to turn it off (wrong-headed but not harmful).

Do you know what the source of the slowness is ? I always found IE6 slow when I did dual-boot.

Try to ping a slow network site an record the times reported.
# ping google.com
PING google.com (64.233.167.99) 56(84) bytes of data.

5 packets transmitted, 5 received, 0% packet loss, time 3999ms
rtt min/avg/max/mdev = 31.037/32.434/35.033/1.558 ms

Then try again under Windows and see what the difference is.

If the problem the DNS resolution ? Try
nslookup slow.site.com
on both systems and compare the times & DNS servers.

As a rule the Linux stack is highly featured, more secure and faster than the Win stack (derived from an old BSD btw), so that's typically not the issue. Most likely your system config of dhcp config has a problem that has you using the wrong DNS server or there is some router config issue that is making the Linux slow. I doubt you have changed sysctl type parameters that would impact the network performance, but since you were led down a bad path wrt IPv6 - please state if you did.

Also perhaps it's something to do w/ your wireless driver or setup. Type "/sbin/iwconfig" in a terminal and report the relevant bits. Here is the output for a relatively poor 802.11g connection:
eth1 IEEE 802.11g ESSID:"blacknblue"

And here from a decent connection ~50ft away (wrt54g):
eth1 IEEE 802.11g ESSID:"bigblue"
Mode:Managed Frequency:2.447 GHz Access Point: 00:13:10:FB:54:50

Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0

The bit rate and link quality tell us a lot about the connection.

So please post some more detail.

I hate to be a pain, but I don't have any more problems. Thanks to everyone who posted, but after I rebooted again (the first time didn't help) my speed issues magically vanished. Now I'm zipping around quite contentedly. :)

Probably the update service as mentioned by zagloba then.
