Getting wireless working on CENTOS 5.3 64 bit
Hi All,

Just installed Centos 5.3 64 bit on a new machine.

It found and recognized the network card just fine but activating it end in errors
Determining IP information for eth1...failed; no link present. Check cable?

This is a wirelss so a cable is obviously not the problem.

If I go into network setup gui I can set the wirelss settings and give my security key (wireless is WEP and open)

It is the asus wireless network card WL-138G but deep down I think it is broadcom BCM4318 AirForce one 54G.

Anyone know any trick to try?

Did you rename the card to eth1? On a default setup, the first wired interface is usually called eth0. Is it possible you have a wired and a wireless interface on your machine?

I did not rename the wireless card

there is an onboard LAN as well, which also does not seem to be working :-)

I don't want to use the wired lan because it is going to be a webserver tucked away somewhere under the stairs in the house

Type as root:

and print the results here.

Try connecting up the wired interface to make sure your modem/router is setup OK and is giving out IP addresses.

Set the wireless to be unencrypted until you have a connection set up.

Ok I have now changed from CentOS53. 64 bit to Fedore core 11 32 bit and that at least recognizes the onboard LAN. I found threads that for the onboard lan to work I need at least kernel 2.6.21 and for whatever reason the CentOs was 6.2.18. Fedora is 6.2.29
