Can't connect to internet after adding Linux Mint to boot menu

[bluecf66]

I recently installed Fedora 11 onto my computer on top of Linux Mint. Originally I was using Mint's bootloader, but I'm ditching Mint soon for another OS so I'm migrating to Fedora's bootloader to make the transition easier. For a while I couldn't get Mint to appear on Fedora's Grub menu, but during that time I could still access the internet on Fedora. However, once I successfully added Mint to Fedora's grub menu, the wireless suddenly stopped working on Fedora (though it still works on Mint.) I can connect to the network on Fedora but it gives me the awesome "host does not exist" message when I try to ping anything.

Any insight as to why this might have happened after I managed to successfully boot Mint from the Fedora boot menu?

Grub has nothing to do with wireless, so it's just a coincidence in timing that it's happened. Did you do any updates that might have been involved?

Yeah, I'm well aware that Grub has nothing to do with wireless. I did run a large number of updates yesterday but they didn't affect my internet this morning. I'm kind of at a loss as to what I did this morning between starting and restarting.

Try checking /var/log/messages for any clues.

I checked out the log and it appears that there are some wacky configuration settings... I'm going to try to set the IP/Subnet/DNS/etc manually and see if that works out...

Yup! That was the key. Still have no idea what caused it. Looked at the logs and nothing seems to have gone wrong when it was shutting down or while it was running but when it started up again it was handing me some weird settings.

For further reference, before I fixed it, my IP was 10.0.0.2 and broadcast address was 10.0.0.255, which did not look correct to me at all (hence I said "wacky" configuration settings.) Looked at /var/log/messages to get the configuration settings pre-"crash," manually set the IP/DNS/Broadcast/etc., and now I'm back online!
