Question Help on Installing a wireless Adapter


I have installed CentOs 5.8 to my laptop. I now want to install a D-Link D DWA-131 wireless N Nano USB Adapter so that I can access the internet without need for a wired link. The instruction with the Nano are for Window only and warn the user to run the setup from the enclosed CD before connecting the dongle. There is no information for a Linux system. I am new to Linux.
Thank you
Don VE3HOL

Hello Don,

Have you just tried plugging it into your computer? Linux typically "just works" when it comes to hardware, please try that and if it does not work then we can go from there.

if, by chance, it doesnt work after plugging it in paste this into a terminal and post the results:
Code:
echo uname: && uname -a -m -p && echo lspci: && lspci && echo lsusb: && lsusb && echo lsmod: && lsmod && echo ifconfig: && ifconfig && echo ifconfig -a: && ifconfig -a && echo iwconfig: && iwconfig && echo resolv.conf: && cat /etc/resolv.conf && echo route: && route -n

I have tried plugging it in and no joy! With a Terminal window open, nothing indicates that something was plugged in. When I plug in a memory adapter, it is recognized immediately.

^ um, without the output from the commands, no one will be able to predict what type of hardware/ drivers are installed inn your system (please remember that we are not there with you and cant see what you are doing, therefore you will need to paste in that diagnostic information in your post so that someone can get an understanding of how to help you).
please use [code] tags.

not sure why it doesnt come on automatically but try:
Code:
sudo ifconfig wlan0 up
it should show up in your network manager applet; if not show us the output of:
Code:
sudo iwlist wlan0 scan
sudo iwconfig wlan0 essid your-router-name
sudo dhclient # assuming your router uses dhcp

^ not sure what the issue is (maybe the wrong driver loaded ?).

i see this
Code:
rfkill unblock all

edit:
fyi, according to your output in post #7 you have an internal intel wifi adapter (not an external d-link wifi adapter mentioned in you original post).
is there a hardware switch for it ?
some more diagnostic info:
Code:
dmesg | grep 3945
rfkill -l
i think the problem is that the driver is open-source but the firmware is not so centos doesnt include it.

Hello horwoodabitibi

Not sure if you are still around, but a few thoughts.

Firstly, in your early posts you refer to "plugging in" a USB wireless card.

Is there a reason for that and for not using the Intel card that is built into the laptop?

Your "lspci" output shows a:

Quote:
0c:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)
which is surely internal.

I've just installed CentOS 6.3 on this old Dell netbook which has exactly the same card in it and that worked directly off the LiveCD and once installed.

Actually, Intel cards are usually the easiest to get working in Red Hat based distributions because the firmware is free from restriction and therefore distributed with them.

I remember installing CentOS 5.5 on a similar machine with similar results.

There have been occasions when the "wmi" module has conflicted with wireless switching in the past. It messes up some of the keyboard controls, but if you are still in the game it might be worth trying:

Code:
blacklist dell_wmi
Where you add that for CentOS 5.8 I'm not sure. In this install it would be added to the file:

Code:
/etc/modprobe.d/blacklist.conf
