Red Hat 8.0 slowdown AND no internet


I've spent the past month tinkering with linux and lurking around forums / web pages / google on the net trying to solve this problem as I REALLY want to get rid of Windows...

Sony GRX550 Laptop
1.6 Pent 4
256 DDR RAM
32MB DDR RADEON 7500 Mobile
Intel Nic
TOSHIBA CDRW/DVD

Issue #1 Network loopback interface - SOLVED disabled kudzu on startup

Issue #2 Red Hat slowdown - seems to bog or skip commands when using GUI - ex. attempting to goto network settings and systmem just hangs. At shutdown unable to shutdown eth0 - Again this all seems to be related to the NIC

Issue #3 No internet. I can enable eth0, but no internet. Using DHCP through linksys router. Additionally, I attempted to manually set the IRQ ... no luck.

Why I'm frustrated - I had no problems with Mandrake 9.0 with either the net or slowdown - but I couldn't find a 9.0 book / bible on the subject to work through sooo I switched to Red Hat. Found a great great book, but above problems are annoying.

I'd love to just set up my WIFI card and run, but I need the net to download the programs *sighs* any help you can offer this newbie is greatly appreciated

Please provide the following configuration files:

/etc/resolv.conf
/etc/sysconfig/network
/etc/sysconfig/network-scripts/ifcfg-eth0

Thanks!

To get the details on these files, do I just open them in a text editor?

thanks!

All you need to do is add a line in /etc/resolv.conf that says
'nameserver w.x.y.z' where 'w.x.y.z' is the IP address of your IP's DNS server. You might be able to get this from your old Windows configuration, if it is still available. This will most likely resolve a lot of your slowness and system hangs.

Another thing that might help things out is modifying your /etc/hosts so that it reads (replace x with IP address of Linux machine & domainhere.net with your domain, if you've chosen one):
127.0.0.1 localhost.localdomain localhost
192.168.1.x JTAlaptop.domainhere.net JTAlaptop

You can get your current IP information by using 'ifconfig' while logged in as root. Also, it's generally a good idea to restart the network services after machine modifications to these files: '/etc/rc.d/init.d/network restart'.

Thank you bentz!!!

I'm happy to say that I am posting from my laptop now! The slowdown issue is cured and the net is running smoothly.
