Mint 12 doesn't recognize wireless adapter ThinkPad SL510

[ndharithreesan]

I am running Mint 12 on my Lenovo Thinkpad SL510. I can use Wired Connections perfectly fine, but my wireless connections don't even show up. When I ran iwconfig in Terminal, I received the following:
lo no wireless extensions.

eth0 no wireless extensions.

I am a newbie at Linux, but can someone please help?!

Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service smbd reload

Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the reload(8) utility, e.g. reload smbd

According to "Linux on Lenovo TP-SL510":

Networking
Provided ethernet card works OK with the r8169 module.

The output above shows that you can ping Google. I don't see anything wrong other than connecting to a wireless connection.

[remoulder]

Does running 'rmmod r8169 && modprobe r8169' make any changes?

Mads, the op was talking about the wifi not the ethernet.

ndharithreesan, can you try in a terminal

Code: Select all

sudo modprobe iwlagn
dmesg | grep iwl

and copy/paste the output here.

I was almost there.

Ok, I think we need more info here. Can you post the outputs of

lspci
lsmod
dmesg | grep -e error -e eth -e wlan

Might be easier to just buy a cheap usb wireless adapter. I use a Belkin 150mz with my desktop.

Hey! Ok here are the results for the commands (sorry for the delay, I can only get to wired internet whenever I go home from school)

I had same problem with my dual boot (Mint 12 /Windows 7) Hp Pavilion Dm1 which has a Broadcom router.
Worked fine in WIndows but would not connect in Mint 12 , I tried all the solutions I could find but to no avai.
I connected with a belkin usb adapter and that was fine.

But it did work when I visited my friends houses who used a variety of routers!

Today magically it is working fine - after 3 months of trying.
So I no longer have the belkin plugged in.

The solution ?
I complained to my BB provider yesterday because I had a speed of 0.2 mps it was fixed for me but by evening even my Compaq running Linux12 was not recognising its wireless adapter (no problems ever before)

Today my BB provider re provided my service and everything now works, the BB provider is UK's BT.

I do have to say this is not the first occurrence of probs with Linux and BT as a BB provider.

fix for wireless not dedtected in lenovo laptops

[ndharithreesan]

mads, i tried that solution and I received this prompt

ERROR: Module acer_wmi does not exist in /proc/modules

how can i identify which module to blacklist?

[mads]

ndharithreesan, I don't know then, sorry.
Three questions that might throw some light on the issue.
What happens if you replace acer_wmi by acer-wmi?
What happens if you try the workaround again but ignore the lines with acer-wmi?
Run these commands. What is the output of the last one?
sudo rfkill unblock all
rfkill list all

[ndharithreesan]

I dont get anything back from running the two commands, just a prompt for another command

[mads]

Sorry, that was just a wild guess since nothing else seems to help.
At this point I would say that I will go for BAD's suggestion.

Might be easier to just buy a cheap usb wireless adapter. I use a Belkin 150mz with my desktop.

[ndharithreesan]

thats the thing....i bought a wireless adapter, but it doesnt work. I mean, it recognizes that there are networks, but when i try to connect to one, it takes forever and fails. I havent been able to connect since i bought it. I got a Netgear n150 usb adapter

[Monsta]

I got a Netgear n150 usb adapter

Now that looks like a second problem in the same thread.
Your lsmod output shows rtl8192cu module - is it for that Netgear USB adapter? If that's so, look at this thread, or start a new one if the problem is different.

Those lspci output really looks like you've disabled the built-in wifi in the BIOS. The SL510 should have either Intel (Centrino Wireless-N 1000, WifiLink 5100 or WifiLink 5150) or Realtek (RTL8188CE or RTL8192SE). None of those cards is visible in lspci. This means the built-in wifi card is dead or disabled.
