Keep looosing Network Connection?

[fvs]

Hello again,
Well I'm back, I have lost my connection to the web once more.
I have on my dual boot machine Win XP and Fedora Core 5, I was up and running on XP, then rebooted and booted up Fedora, only to find that i couldn't get on line? I have been running online in Fedora for about 6 days without a hitch. My Network say's I'm activated,But I can't get on line, My firefox is running, yet it can't find the servers? I tried to restart with the /etc/init.d/network restart command and all commands I know, Maybe someone else that had this problem can help? Thanks. fvs

Try using ndiswrapper to install the windows drivers.

Windows work fine, The lost connection is in Fedora. Thanks

Does your Fedora system use DHCP or a static IP address?
What's in /etc/sysconfig/network-scripts/ifcfg-eth0?

Hi Falko, I can't seem to get it together, :mad:

Can you try this in /etc/sysconfig/network-scripts/ifcfg-eth0?

DEVICE=eth0
BOOTPROTO=static
BROADCAST=192.168.0.255

ONBOOT=yes
GATEWAY=192.168.0.1
DEFAULTGATEWAY=192.168.0.1
Restart the network afterwards: /etc/init.d/network restart
Your system should then have the IP address 192.168.0.3.

Is 192.168.0.1 your gateway? Can you ping other systems in your local network?

Where does 169.254.0.0 come from?

What ethernet card do you use. Download its latest driver from the manufactures website and then extract them with cabextract (yum install cabextract). Install ndiswrapper

http://www.linuxquestions.org/linux/?q=answers/Networking/Ndiswrapper_in_Fedora_Core_5&

Then run cabextract on the .exe file.

Install the required .ini or .inf (google this) and then type depmod -a and then ndiswrapper -m and you should be good.

Can't go to web site, I can't get online with Fedora 5, I'm writing you in Win XP system. Need to get online in linux fedora Core5.

Fvs,

It looks like your eth0 is coming up fine, but that you may not be getting DNS information.

For giggles, try to ping yahoo.com by using its IP address:

ping 66.94.234.13

and see how that goes. If that works then it is a DNS issue.

HTH,

Jim

[22hosting]

I really hope this isn't as easy as I think it is. If you can ping an ip address (any address at all) your ethernet is working, and network connectivity is NOT your issue. Your DHCP appears to have assigned you an address (as show by ifconfig).

If you try pinging by name (NOT ip) you will probably find it can't. The reason being it CANNOT resolve names. You need to specify a dns server in /etc/resolv.conf .

Therefore firstly :
cat /etc/resolv.conf
to see what you got.

Then pico/nano/vi your /etc/resolv.conf file and add in this at the top
nameserver 82.138.242.202

I would only recommend using this entry for a short time as it's my DNS server, and your ISP should have one you can use instead. You could probably also use your routers/gateway IP (192.168.0.1 or whatever it is).

UPDATE :
Ok, i decided to re-read a couple of posts here. You cannot access an external network. So check the following :
cat /etc/sysconfig/network

Make sure you have a line like : GATEWAY=192.168.0.1
You must specify your gateway address else you'll never get an external connection.

Thanks for reply, I have it working now with a lot of tweaking and luck,
Don't ask me how, i just set it back to DHCP and it came back on reboot?
Hope it lasts after next update. Thanks.:) fvs

I can't go any further,I'm stuck with out an internet connection.
Once again I take one step forward and two steps back, This time all was going well with my internet and I thought that I would start going ahead and download the programs that would help personalize my system, I used update to update my system the and commenced to install samba, anjuta and a few other things, I guess in the update it included a new kernel 2.6.16 and when I rebooted once again and found Once more I hadn't a connection to the web and no server. Went through all the connands & code we did in the last two weeks the last one, etc/init.d/network restart and found error message that said something about errors and refered me to /etc/syscongig/network-scripts/ifup-eth, I don't know what I should look for? This FC5 is rather differcult to handle for a novice.
I'm glad to have your help, Thanks fvs

[22hosting]

Check /etc/sysconfig/network-scripts/ifcfg-eth0
it will contain your ethernet address information.
