I have had the computer hooked up to a different wireless network. I have moved to a new location and have gotten a new wireless router. Everything is up and running on the centos5 box, I can see the network but when I try to connect to it I get no IP number and can't connect to the Internet. Here is the info I got:

hi,
looks like the new router may have security on by default, make sure its off and you dont have access controll on, also make sure dhcp is on, on your router and machine.

try using or run as root

I checked all is their, I have some Windows boxes running just fine so I think DHCP is working fine. I also see that the centos box is trying to get an IP address.

i tried those commands under root and it came back as command not found.

I'm assuming you have some other DHCP tool... but to be sure, could you install dhclient and then run it?

dhclient ra0 worked and it gave me back no DHCP offers received. No working leases in persistent database - sleeping.
