My atheros wireless card is obviously loaded as I'm able to ping my router & get response. I installed wpa_supplicant set SSID & Passphrase but everytime I try to get online get message "unknown host".
Os LFS7.2.
Btw "iwlist wlan0 scan" does list the available networks.

Since everything else appears to be working, consider DNS resolution for this last problem. Have you got some nameservers in /etc/resolv.conf? Or if you do, try some different ones, say, OpenDNS's (208.67.222.222, 208.67.220.220) or Google's (8.8.8.8 and 8.8.4.4).

I looked in my /etc/hosts file & it was empty so I included my dns nameserver but it didn't change anything.
What I have installed is wpa_supplicant & dhcpcd also network support for ethernet, which is not necessary as I'm not closed to an ethernet cord. I would like to know what steps I can take to remove all network & dhcpcd software & reinstall.

I saw this post after posting but would like to know if "make uninstall" would work in my case as my packages were installed from sources directory.

Put those in /etc/resolv.conf. See section 7.2.3 of the LFS 7.2 book.

Since scanning finds networks, then your device and driver are working IMO. And you said you can ping your router, so you have established a connection with it IMO. To me, wpa_supplicant has negotiated an encrypted connection with the router, and dhcpcd has acquired an IP address from it. If you can't ping an Internet URL, then try pinging an Internet IP address. Say, one for www.google.com such as 173.194.75.104. If the IP address does get replies, then that sort of confirms DNS resolution as the issue.

Thank you on my back to 7.2.3 post back in a few

I tried pinging an ip address no luck.
I also was able to use wpa_cli & got CTRL-EVENTS AP-AVAILABLE, after going thru all of the steps in wpa_cli & getting ok still not connecting.

can you please post the following:edit: while your at it please post the following diagnostic info:

FInally figured out my problem. I read up on dhcp & dhcpcd & obviously installed the wrong 1 should've installed dhcp instead of dhcpcd. Itns going to be a few days before I get back to install but positive that is issue. Also after playing with wpa_cli iwconfig showed my network was associated but couldn't get to internet.

I'm finally able to connect to internet, although I did reinstall lfs.
This time I didn't use dhcpcd, nor did I use dhcp.
When I installed wpa_supplicant I went ahead & installed dbus & it's dependencies & reinstalled lfs-bootscripts.

The only problem that I have is that network doesn't survive reboot.
On boot I get message: [ 8.031913] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready.
For 1 the dwext driver isn't loaded automatically.
Each time I want to connect to network I have to use wpa_cli & enter everything manually.

I need to work on it a little bit more & try to get dwext to load on boot

I haven't had the opportunity or need to use wireless for my BLFS systems yet, but I did this sort of stuff manually and with scripts for years with various distros before I ever heard of NetworkManager. Anyway, I don't think you have to worry about wext getting loaded. If you are establishing the connection satisfactorily by hand after booting, then consider a custom init script to do those final chores that you're doing manually.

I just saved my commands for wpa_cli to a file to copy & paste.

Very well.

For fun someday, take that text file with the commands that you mentioned, add a bash shebang line at the top, save it with an appropriate name in /etc/rc.d/init.d, make it executable, create a symlink to it in /etc/rc.d/rc3.d as the last script to start, reboot and see if you're connected. It might work.

i know in fedora you can put commands in /etc/rc.local and they will run when the system boots up.

or you can put stuff in ~/.profile or ~.bash_profile and they will run when that user logs in.

or you can put an @reboot entry in your crontab and the command will run after every reboot.


there are many ways to skin this cat.

Lost my system installing pam so I had to start all over.
