I installed Fedora 10 on a computer that now tri-boots; WinXP, Ubuntu and Fedora. The install went well, except that I had to edit my Grub, menu.lst to get Ubuntu back. But Firefox in Fedora 10 will not connect to the internet (neither eth0 or wlan0). I have checked, in a terminal, if eth0 is up and it is and it will ping Google. Both WinXP and Ubuntu have no problem accessing the internet, so it isn't a hardware problem. I had tried Suse 11.1 on this computer and had the exact same problem. I tried disabling SElinux by putting selinux=0 in the kernel line in grub with no success.
lspci indicates the lan card is present
ifconfig indicates eth0 has an ip address
dhclient eth0 checks out
ping www.google.com sends and receives pings
But Firefox will not connect

Any suggestions?

How are the netwoksettings from firefox?
any proxy perhaps ?
firewall?

My network consists of a Belkin router and a DSL modem. I don't use proxies. DHCP seems to be establishing IP address ok. Like I said, it pings Google ok. Also Add/Remove Software won't connect to get the list of packages. Its like the machine has an internet connection, but the OS won't use it. I'm not sure if Fedora has enabled a firewall by default? Does it do that? How would I check?

I have the same problem. I did a fresh Fedora 10 installation.

firefox won't find a page, the problem seems to be somewhere between firefox and the ethernet adapter??


I look at the connection information:

System eth0 (default)

Interface: Ethernet (eth0)
Hardware Address: 00:0B:97E:54;E7
Driver: e1000e
Speed: 100Mb/s
Security: None

IP Address: 192.168.1.13
Broadcast Address: 192.168.1.255
Subnet Mask: 255.255.255.0
Default Route: 192.168.1.1
Primary DNS: 192.168.1.1
Secondary DNS 192.168.1.1

the ip settings are the same as on my windows computer.
I can ping 94.102.146.98
I can ping www.google.com

PROBLEM seems to be DNS I can connect to google with direct ip address.

thanks,
robert

have you tried turning off IPV6 in firefox 3 ?
type
into the address bar
then in the search -- this:

network.dns.disableIPv6

and toggle it from "false" to "true"

I tried that no luck...

I am stumped.

I notice that if I up the byte counts in ping, I start getting losses!!!

I while ago, I saw a thread where they suggested to install
mozilla-firefox-devel
to resolve the DNS issue.

Can you surf using another browser? opera, lynx ....

without the browser, it is a pain to download and install anything. When I installed fedora, it wouldn't connect to any internet repository either. I think something might be messed up with the network drivers not just mozilla.

robert

it is possible that "network Manager" ( mostly wireless) is having a problem .It is on by default .
"Network" is OFF by default

in the services turn OFF "network Manager" and turn on "network"
then config using "network"
there should be a tiny icon on the upper toolbar for that

I had the same problem. There appears to be a bug in the network manager. I went into the script file for eth0 and set my ip and gateway manually. That made firefox work. /etc/sysconfig/network-scripts/ifcfg-eth0.

The bizarre thing I ran into is even after firefox was happy. I couldn't get yum to run until I set the DNS to the opendns addresses.

It is hard to belief that this supposed to be a mainstream OS.

good luck

Thanks for the update rebible. I'm glad that you got it working. I managed to fix my box by un-installing Fedora and installing Arch Linux. Arch is a little different, but the internet works. My only complaint with Arch is the fonts look like Linux from the 1990s.

Sorry about my english

In my case I make new wired connection with the same mac address
from "Network Manager applet" and everything work fine!

that's funny, my problem is just the reverse: mepis and fedora connect great, vista (which used to connect great) now does not connect very well

I am a newbie. Had the same problem as mentioned in this thread. I tried the ipv6 toggle suggested by one of the posts and it worked. It is fedora 11 and firefox 3.5.3.

It would be great to know what exactly the issue was.

thank you!
