Ethernet Issues

Dear All,

I was having trouble getting my network cards to work in Slack with my new wireless-and-wired router. So I'm trying Fedora out of the irrational belief that it will solve my problems. It isn't.

Both of my cards work in Windows. In Fedora, the message log says it recognizes my Broadcom and Pro Wireless cards, but then it fails to find IP addresses for them. The Fedora Network administration software says they are set for DHCP.

I can't find any /etc files that say "IP_ADDRESS=bla.hbl.ahb.lah" and iwlist doesn't exist, though I saw it as a suggestion in another thread. What do I try next?

First is it loading drivers for the cards, if not then the cards won't work. Some of the broadcom cards don't work with the linux driver either, just because the message log gets info from the pnp card doesn't mean the driver is loaded or working properly. Also as for iwlist you may need to download a wireless utilities package, don't know what it might be called in your distro. If you have any encryption setup you may need to adjust those settings remember if you have WPA running on your router you need wpasupplicant, and it has to broadcast it's ssid. Finally is your device setup, i.e. do you have a wlan0 in your ifconfig, if it's not there I would put my money on drivers not being loaded or the driver not being the right one.

Dear All,

After spending the week educating myself and receiving much help along the way, I have eth0 working. wanl0 is still not working.

Here's the ifconfig output...

Code:

# ifconfig

When I use the network configuration dialog in KDE, and try to activate wlan0, I get this:

Code:

SIOCSIFFLAGS: Input/output error
Error for wireless request "Set Frequency" (8B04) :
    SET failed on device wlan0 ; Input/output error.
Error for wireless request "Set Bit Rate" (8B20) :
    SET failed on device wlan0 ; Operation not supported.

Determining IP information for wlan0... failed.

DHCP is on, and my WEP key is stored in the configuration - copied and pasted, so no typing errors. What should I do next to get my wireless card working?

I get that same error when I try to do "sudo iwconfig eth1 channel auto"
If I set the channel manually (in my case "sudo iwconfig eth1 channel 1") it works fine.

Do a "iwlist wlan0 scanning" to see what channel you should put in the above command.
