View Full Version : FC4 - NetworkManager doesn't connect, but AP shows assigned IP

I've just completed a clean install of FC4 on an IBM Thinkpad T30 (2366-MU9) w/ a Cisco Aeronet Wireless Card and cannot "connect" via NetworkManager.

I've checked my access point and it has "correctly" assigned my FC4 box an IP over WEP (128-bit). So, this tells me that my NetworkManager configuration is correct ... thoughts as to why I can't get on the web?

What does "ifconfig -a" and "netstat -rn" tell you? Might have to run the first as root, don't remember.

Hi Capn!

ifconfig -a says:

Link encap: Ethernet HWaddr 00:02:8a:40:d1:7d

netstat -rn says:

You don't have an IP address assigned. Thee 169.254 address listed by nestat -rn is from the zero configuration option. This does nothing for you and can be ignored or turned off.

iwlist scan

Should show you the access points available in your area.

There have been a few users which have reported similar problems.

Run the command:

iwconfig

to get additional information on your wireless network.

Most likely it will tell you that your NIC is not associated with an access point.

Review your options and make sure your wep keys match. Check the log file for any specific errors when starting the wireless interface.

Some users have managed to get things working by commenting out or removing the CHANNEL line in the ifcfg-* confiiguration file.

Actually it looks like you have an IPv6 Address assigned. Did you tell your router to use IPv6 instead of IPv4? Is there a reason for that? IPv6 on Linux is over my head, so if that's what you're really using, I can't be of much help. Sorry.

You are also showing a lot of errored packets there.

I would try the suggestions in the previous post.

Are there wireless access points that support IPV6?

My laptop currently shows a similar IPV6 address but I am not using IPV6. (actually I need to disable that on this laptop)

I show a regular IPV4 address as well which is how I am connecting to the LAN.

Good point about the error counts.
