DHCP conflicts?
 

Greetings
Running a DSL internet connection to a Actiontec modem.
The windows machine is connected via wireless and works fine except for the daily 'blue screen of death'

Hence the attempted migration to linux...
be advised: linux newbie!

Running Fedora 4 on a amd 900mhz, connected to Actiontec dsl modem via hardwire and network card.
Card is functional

Internet access was intermittent (some pages loaded, most did not) until running across dhcp mini how to.
Unfortunately, can't post the url until I've made three posts to the forum.

As root, added
"route add -host 255.255.255.255 dev eth0"

Internet access improved significantly under root expect "ping" which produced 100% packet loss.
Also, after logging in as "any user" internet access returns to intermittent (some pages load, most do not)

What more do I need to do?
Thanks in advance

Hi,
DHCP should give you an IP address, a netmask, a gateway and at least one nameserver.

the IP address is your address, the mask gives you the information of who's on the same network as you are.
The gateway is the IP that is the gate to the other networks (internet) and the nameserver is the IP of a machine translating IP addresses to names (and the other way round) so that you can ping www.google.com instead of 66.102.9.104

Since DHCP gives you a gateway, you shouldn't have to use the route command (which is use to manually add routes, ie gateways to other networks).

Could you please post the output of the following commands, as root:
ifconfig -a
route -n
cat /etc/resolv.conf
iptables -L

Also, if you know it, give us the IP address of your dsl modem.

thanks for the info
here is the requested output:
