Fedora 17 64 bit wifi hardware not detected

[j2rjadeja]

Hello

Wifi is not working after installing fedora 17 - 64 bit on lenovo e450 thinkpad.

Hello j2rjadeja

The same make of laptop can have several different wireless chipsets inside it.

It's the chipset that determines what action is needed to make it work in Linux.

If you run the command:

lspci

and post back the parts that relate to "network", "ethernet" or "wireless" that should identify the chipset and someone may be able to help.

If that doesn't identify two devices then possibly one of them is a usb device soldered to the main board. The command:

lsusb

will probably reveal what we need to know in that case.

Hello j2rjadeja

This:

03:00.0 Network controller: Intel Corporation Device 0888 (rev c4)

appears to be your wireless device.

Unfortunately the simple form of the "lspci" command doesn't reveal enough about it to see what other people are doing with it.

Try running:

lspci -vnn | grep Network

and post back what that gives us.

[j2rjadeja]

Thanks for reply.
The output of lspci -vnn | grep Network is

03:00.0 Network controller [0280]: Intel Corporation Device [8086:0888] (rev c4)

Hello j2rjadeja

Searching on Google for:

8086:0888 Linux

doesn't bring up much information except reports of intermittent connectivity. The implication being that it can be made to work at least partly.

Can we try:

lspci -k | grep Network

and see if a driver is claiming the card.

If it is, then there are several Intel firmware packages available that don't get installed by default - at least from the liveCD.

It might be worth installing them, they certainly won't harm the system.

yum install iwl105-firmware.noarch iwl135-firmware.noarch iwl2000-firmware.noarch iwl2030-firmware.noarch

will do it. See if NetworkManager recognises the card then.

[j2rjadeja]

run this command
lspci -k | grep Network

and the output is

03:00.0 Network controller: Intel Corporation Device 0888 (rev c4)

Thanks bfuller

yum install iwl105-firmware.noarch iwl135-firmware.noarch iwl2000-firmware.noarch iwl2030-firmware.noarch

Run this command and then restart and my wifi has start working.
Thanks for quick reply.

Hello j2rjadeja

Apologies, I've just tried to make the "lspci -k" command work with grep and it didn't.

What I was looking for was something like the output for my card, quoted below:

0c:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)
Subsystem: Intel Corporation Device 1021
Kernel driver in use: iwl3945

Try just:

lspci -k

and see what you get for your card.


Ah, I see you've just posted at the same time as I did. Pleased to see you have success. Just remember what I said about people reporting performance as intermittent. It appeared to be a kernel bug and was being talked about sometime in the second quarter of this year.

[stevea]

Yeah - wow this is painful to watch. Both of you please read ...
http://forums.fedoraforum.org/showthread.php?t=282819
for next time.

"lspci -nnk" is the best command to use since it shows the vendor/device ID AND any driver installed. If you need to prune the output then try "lspci -nnk | grep Network -A5".

The device 8086:0888 is an Intel Wireless-N 2230 (BGN).
It should use the iwlwifi driver (default in any kernel)
The firmware needed is in the package "iwl2030-firmware" and the file is
/lib/firmware/iwlwifi-2030-6.ucode


With the firmware installed reboot.
Do the "lspci -nnk" or else "lsmod | grep iwlwifi" to see if the driver was installed.
Find the interface and some basic interface commands
ip link # shows the interfaces, might be called 'wlan0'
iwconfig # should show the interfaces and the wifi settings

If you don't see the driver or can't get a response from iwconfig, then look through this command for an error
dmesg | less

NetworkManager (icon on non-taskbar) is the best way to manage wifi.
There are sometimes problems that require disabling A to get N wifi bands. Unlikely but be aware.

Hello stevea

Thanks for the encouragement.

I'm' sure no one forced you to read the thread.

I had this same problem on my wife's Toshiba Satellite. The workaround I found was this:
Get into Bios and disable the Ethernet. Then reboot, and and the Wifi will then work. All I needed was to download broadcom-wl, and it works every time.

[j2rjadeja]

What i did was just downloaded intel wifi driver and restart. wifi start working.. :-)
