slackware wifi problem


ok i cant get my wifi to work i checked in the slackbook and on some forums and also on the internet but i cant find out what my wifi hardware is called or even where to start to try to fix the problem. my wifi light is on but no connection. i tried iwconfig and it said
lo no wireless extensions
eth0 no wireless extensions

then i tried netconfig but i dont understand. there is no man pages on it. in the slackbook it showed me some files i can edit but i dont know how to use emacs or any type of text editor but some of the forums i was reading they didnt have to use a text editor to fix there problem. I also tried lsmod but i dont know what im looking for on that either. so wondering if anyone can help thanks in advance if you need any info just let me know.

What make model/computer and what type of wireless chip. The more information you provide, the easier it is for persons to help you.

If you are not sure what kind of chip, try running dmesg in a terminal as root and inspecting the output for the bit that describes your wireless chip. Dmesg outputs a log of info; be prepared to do a little scrolling through the history.

I agree with franbell, what is the make and model of your computer. In addition to dmesg, try running lspci too.

Hi,

From the 'cli' do 'dmesg |grep -i wireless. As to the 'lspci', do it from the 'cli' as 'lspci -vv' and look for the wireless information or try 'lspci -vv |grep -i network' (omit ticks for all commands). You can experiment with the command argument parameters. Do a 'man command' to learn what the options are.

If your device driver & firmware are in place then Configuring your network in Slackware is Alien_Bob's excellent article on the way network cards are configured in Slackware. Loads of internal reference links for Ethernet & Wireless

these commands are to help us to know what your system thinks is installed (not necessarily to get you connected).
Code:
lspci # will tell us the pci devices you have in your system.
lsusb # will tell us the usb devices you have in your system.
ifconfig # will tell us what network interface cards you have turned on in your system.
ifconfig -a # will tell us all the network interface cards you have in your system.
iwconfig # will tell us which of your network interface cards has wireless capability
now that we know that, this should get you connected:
Code:
sudo iwlist device scan # this will use the device interface (that from the above command, we found out has wireless capability) and scan for wireless routers that are accessible.
sudo iwconfig device essid "myssid" # assuming no security, use that device to connect to your router.
sudo dhclient # will attempt to get ip-address, subnet mask, dns server information automatically from your router assuming dhcp is turned on on your router.

Post the output of lspci and lsusb so maybe someone can tell what type of wireless card you have.

According to the HP product specs it has an HP 802.11b/g/n WLAN card which, according to this, has a Broadcom chip.

cli refers to the command line terminal. Could also try lspcmcia and see if anything shows up that way. lspci may be seeing it just don't know what it is.

If you have a usb key can copy and paste the output of the commands from one of the desktop terminals to a text file and save to the usb key, or write it all down and type away. Have to be root for the commands to work.
