Issue with wireless on Lenovo Z570
I have a Lenovo Z570 laptop, on which I've installed 64-bit CentOS 6.2. The wireless worked for a while, but then suddenly became disabled, and I don't know how to reenable it.

I found some things on the internet about my card and linux drivers (search "intel wifi drivers linux"), but to be honest, after reading everything, I'm still not sure if anything on this site can help me, or what I'm supposed to do. I found a site where I could download microcode, but, again, I'm not sure what to do with it. Also, there's a page that says to use "intree" drivers, which I'm guessing are those already distributed with my kernel, but I don't know how to do this.
The laptop has a key for enabling/disabling wireless (Fn-F5), but pressing this doesn't help. Also, when I first boot, I can go in to the BIOS, and there's a control to set wireless enabled/disabled. It's set to enabled, but still it looks disabled from a hardware level.
Thanks in advance for any help.

Thanks for the reply.
That's a good idea, actually. I could even do a system restore to Windows 7 and confirm that it is indeed a linux kernel issue.
One update on the problem: I tried contacting Intel about the problem, and they told me to move a microcode file to the /lib/firmware directory on my computer. However, the microcode file is already there, so it didn't end up being helpful.

Just some off the wall info.
Back when I had Ubuntu Netbook distro on my Acer Aspire One zg5 atom Netbook.
I had a problem mounting external SD flash cards when plugged in while running.
I followed a erroneous tutorial, (from Ubuntus site I may add), on a fix for this which required me editing the kernel line in Grub menu. After that edit. I would lose internal wireless card after about a hour to a hour and a half.
After the netbook stayed off for a while. It would fix itself. I even ran a external wireless wireless USB stick and had no troubles with dropped wifi.
So digging into the problem. I figured out my kernel edit had some how snafued the wireless card or motherboard to the point the internal wireless card was getting hot and dropping out. So after I redited my kernel line and deleted the changes I made. No more dropped wireless. Weird huh?
Probably not your problem but I figured I would mention it.

So here are some updates on the problem: I tried booting from Knoppix, the wireless card still appears disabled. I tried rebooting, disabling wireless in the BIOS, and allowing the boot. Then rebooting again, reenabling the wireless, and proceeding with the boot. This didn't fix the problem, but when the system came up with the wireless disabled in the BIOS, the result was different (instead of showing up as hard blocked by rfkill, it didn't show at all--meaning both in the icon in the upper right of my desktop, and when I do "service network restart" to bring up the network interfaces, the error message is different, like "no wireless found" instead off "card blocked by rfkill'>
Currently I can think of two more things to try:
1. Try reverting the system to Windows 7, see if wireless works
2. Do a BIOS upgrade (the BIOS seems to be from Oct 2011)
However, it might be a week or more before I'll have a chance to try these, so if anyone can suggest something else, I'd really appreciate it. It's very frustrating, there are a large number of Google results for "Lenovo Z570 linux wireless", but in all cases either it worked for that person, or they were able to fix the problem, but it's not the same as my problem
Thanks in advance for any additional comments

Hallo. I am suffering from an Identical problem. I have an Lenovo Ideapad Z570. After Windows crashed I was using a Live installation of Ubuntu to save my data and try any repairs. The wifi was working perfectly, after saving my data and using the live edition for three days I decided that yes the time was right for getting rid of Windows on the machine. I went to install and the computer said it was not connected. I carried on regardless. When I got to the partitioning screen, I needed some further info, so I rebooted to the live installation. The Live installation said exactly the same thing. The hardware switch is disabled. I tried the switch in both postions and possibly a few that don't exist. Then I checked the Bios and it was enabled. I could not switch it on. Boredom and lack of Internet then took me over and I fresh installed Windows 7. With Windows 7 on the switch still did not change anything however the 'Fn' and 'F5' instruction bought up a little energy managment screen which switched it back on and everything worked fine.
Today I decided to make the machine a dual boot with Ubuntu. Again got to the installation screen and the wireless has disappered again, booted up the live installation and still no joy. Tried using the 'fn' and 'fn5' command but this seems to be a Windows only command (is this the correct terminology?). So here I am writing this back on Windows 7. It looks like to me that the 'Energy managment driver' controls the software disabling of the wifi and somehow when you go to installation this trips it out somehow!!( correct terminology) . Looking for a solution the first thing I've come across is an identical problem. Any solution guys?? Really looking forward to using Ubuntu. Thinking of installing through Ethernet and then trying to find a solution then. Thanks for any help

Here's the status of my situation: once I reinstalled Windows 7, I got a message that my problem was that the hardware switch on the front of the machine was switched to "off" (doh!). So it would appear that this was a stupid oversight on my part, I noticed that you could switch on/off wireless using Fn-F5, I noticed that you could switch on/off wireless from the BIOS, but I did not notice the switch on the front. Once I switched it back, I got wireless again, although I have not tried going back to Linux, although at the moment my belief is that it would work fine (the reason that this is my belief is that our company bought 2 identical machines, and I put linux on both of them, only mine had wireless problems, and since then I've figured out that the issue was, to my knowledge, the switch on the front).
For the record, my Linux is Centos 6.2, maybe different results than with Ubuntu.
