All internet connection gone since FC4 to FC5 upgrade

[neilloffhagen]

In the end decided to give an upgrade a try. Had a working FC4 box that was fully updated. Had downloaded the FC5 DVD and set that up on an ftp server in my home lan. Booted off the resue disk and installed from the ftp server. All seemed to go fine. Booted up okay and logged in okay. The apps I tried started up okay, but can't browse the net? Did this on Friday and spent time over the weekend trying figure out what had changed to stop the net being able to be connected to.

As mentioned in http://www.fedoraproject.org/wiki/YumUpgradeFaq did the "/sbin/fixfiles relabel" (but didn't delete all the temp files) but it didn't seem to make any difference. Also, turned off SELinux and the firewall, just to see, but no difference. The network card is working as I can connect to some samba shares on another (debian) machine. That debian machine can connect to the net, so the ADSL line is working. The upgraded FC5 machine can resolve names - I think - as when I ping www.google.co.uk it gives back an IP address but says it cannot connect. yum also fails to make any connection. Tried Opera in case there was something wrong with firefox, but get the same problem.

Anyone any ideas what may be wrong so I can try things when I get home tonight?

I did mention this in the midst of the Fedora 5 installation poll, but thought it might get lost in there :)

Thanks

I have had a similar problem. I upgraded a week ago, and have spent the past week frustrated to no end trying to figure out what I did wrong, or what settings changed, or what have you. I have not found the answer yet. I have noticed one additional piece of the puzzle to the original posting: When I ping from my local machine (192.168.10.5) to my home router (ping 192.168.10.1) and let it run, it will answer correctly for a couple of minutes, then stop working for a couple of minutes, then start again, then stop again, and so on.

...

I cannot discover any rhyme or reason to the uptime or downtime.

I should add as well that I have the same trouble using either a wireless connection (using ndiswrapper on wlan0) and a wired connection (eth0).

I would greatly appreaciate any insights.

Peace!

Getting a bitbfrustrated by not being asble to figure out why the interent was not wokring on my upgraded FC5 box decided to do a new install saving my home drive. Again then install went well, actually a lot quicker than the upgrade went, agsain using the DVD image which has been made avialble on my ftp server. Exactly the same though. No interent at all? Everything esle seems okay. Printer installs, sound plays, Openoffice works, but no interent? Could there be something wrong with my download, so that some files are missing? The mdsum is okay. Whatever is wrong may be fixed if could run yum, but as no interent access on this one machine it doesn't work. Is there a way I could get the updates on to my debian ftp box and yum pointing to there?

I have a similar problem too. I installed FC5 on friday and it was all working well until I changed some seetings on network. All I did was to change the router setting from dhcp to static, and yes, i did change the network settings on my comp to static too. Since then, the internet went down on my comp. I have all other computers working properly but the FC5 computer. I just couldnt take it anymore and since it was a fresh install, I re-installed FC5 again and to DHCP network setting.
Now this is whats happening...
Internet works for 30seconds and then the icon on the top says "network disconnected"...
So, I unplug the cable and plug it back in again and now says "network connection"...
Internet works for another 30 seconds and repeats again..
What is going on here?????

I'm using a static IP too. Tonight if I've time I'll change the router/firewall back to being a DHCP Server and see what happens then. From what you say it won't work, but it's worth a try.

Fixed. The answer is in another thread - http://www.fedoraforum.org/forum/showthread.php?t=101357

It was that the NetworkManager had not started.
