When doing a new install, my system works fine until I do an update to the latest kernel.
I am using F7 and have loaded the initial Fedora 7 distribution several times and everything works fine. I update everything but the kernel and am still able to access the web. Once the new kernel is installed, the web access ends.

I am able to check the ifconfig, and it is the address that I assigned to it, unable to ping outside my intranet. I can access the computer on my intranet, unable to access my box from the internet. My web page is down. The network card works correctly in MS-Windows. I can do a fresh install to the old kernel and everything is fine.

Any suggestions?

Need more information??

Hardware net drivers are often externally compiled kernel modules and are sensitive to differences between kernels. It seems possible the the driver for your card was not updated correctly for the new kernel. If that's it, and if you're comfortable compiling source code, you could locate the source, download it, update the kernel, then compile a new version of the driver appropriate for the new kernel. You'd need to have installed the development kernel headers for this, because they're required for the compilation. Or maybe you can find a new pre-compiled driver for your card and for the new kernel version, probably on the Livna site.

If you need to ask further, I think you ought to give much more detail about your network card, the output of ifconfig, and any relevant kernel messages in dmesg.
