[SOLVED ??] Lenovo Edge E520 No Wireless

Post by Canuck »

I have just tried to run Mint 11 Live. I have WiFi wireless LAN adapters Thinkpad 1x1 b/g/n

Mint 11 does not detect any wireless signal. I have my laptop within 2 feet of my router. Of course, Windows 7, did find the signal. BUT, I want to install and use Mint 11. I have no desire to dual boot.
Until I can find out how to get Mint 11 to 'find' my router, I will not install Mint.

I really need help. I am committed to using Linux, specifically Mint 11, 64 bit. The computer will be returned if I can't get Mint to work

HELP is needed.

SOLVED??? It would appear that the problem lies with the current kernel and will be fixed with a kernel update. Which I have not attempted at this point.

First you have to know what chipset your wireless device uses so you know what driver to install. If it's internal can you run 2 codes in terminal and paste here the output it gives you?

Code: Select all

lspci
and

Code: Select all

inxi -N
and if it's USB, then just

Code: Select all

lsusb

Since I haven't got a printer connected to the Lenovo, I had to copy what I thought were the appropriate lines.

No problem. Can you do a

Code: Select all

lsmod
and paste that back here? Need to see if any other drivers are trying to claim the device.

Ok, I am not familiar with that specific model of Realtek card, but my search shows that there is a specific driver for your card that is RT8188CE or RT8188CE-VAU (no idea what the difference is but I'm sure it's important). Info http://www.realtek.com.tw/downloads/dow ... #RTL8188CE

From your post it shows your card is using the RT8192CE driver instead. I don't know if that is compatible with your card. Hopefully someone will pipe in with experience troubleshooting it.

Further information:

I produced the lspci, inxi -N, lsmod printouts using Mint 11, LIVE, on my Windows 7 Lenova. Yes, the wifi works just fine using Windows 7. Home Premium 64. MINT is not installed. Am I missing something? When I look at the Realtek driver listings which you directed me to via the link, I would think that the correct drivers are installed. I am quite ignorant of these matters, however.

Re: Lenovo Edge E520 No Wireless Need Help

Post by Canuck »

I have tried several current Live distributions and none of them to date detect my router, a D-Link.
So far on this forum, I have been given to believe that I lack the appropriate Linux driver. It may need to be downloaded from the Realtek website; Here is my problem:
My Lenova E520 with Windows 7 does detect my router.

My options appear to be:

1. Look for a Linux Live distribution which has the correct driver.
2. If I need to install a driver, I have no idea how to do so
3. Wait for an update Linux kernal which likely will have the new appropriate driver.

I would appreciate help with this issue. I really do not want to install Linux until I know that the wireless will work.

Please help me. IF I need to install a driver, I would appreciate specific “how to” information, as I am not at all familiar with the procedure.

updating kernels has never been so easy for Linux these days.

you will just have to play with kernel sets to find the one the delivers all.

Remember to download BOTH header packs and image to build headers etc.

Here you find pre compiled pre patch kernels

http://kernel.ubuntu.com/~kernel-ppa/mainline/

Here is ubuntu natty 2.6.38-9.46 series

https://launchpad.net/ubuntu/natty

Just type in 2.6.38-9 in the search

I have encountered many laptops and net books with wireless or Ethernet missing etc. Every time I have been able to find a kernel that delivered all.

This round , for my netbook , laptop , both desktops 2.6.38-9 delivered the gold.

Last time with Maverick it was the natty final sets starting with 2.6.38.2 all the way to 2.6.38.7 .

Play and try, remove via synaptic what ever you don't need or didn't work.

Yes I have tested them on Linux mint 11 and all passed fine on about a dozen systems now.

Thank you Gúrú Linux ríomhaire

Several questions which will clearly show my low level of knowledge regarding this issue.

I went to the pre compiled, pre patch kernel link. Checked several of them and the 64 bit kernels were labelled AMD 64. Am I correct in assuming that these kernels would work with Intel i3 64 b??
Am I correct in assuming, based on what I have learned this far, that I will need to install, rather than using Live, Mint 11 64 b. before I can search for kernels and install them?
Am I correct in assuming that when I download one of the kernels that it will install automatically? If not what do I do to effect the installation? I have used Synaptic a great deal and know how it works, but this seems to be very different.
-As for these new kernels and headers, they will not yet be on any Repository, correct?
It sounds to me like it is a kernel problem and that your advice will be invaluable. But, I want to absolutely sure that I do all things correctly. I wish that there was a way that I could test the kernels before I wipe Windows 7 and install Mint 11. I have been using Linux for over ten years and am committed to continuing to do so. (I am embarrassed about how little I have learned in that time) I bought this laptop with the intention to using Linux Mint 11 exclusively (not dual boot).
Thank you for bearing with me.

Yes - tested as fully working on Intel x64 as well i3 i5 i7 tested

Install is simple, use gdeb install tool , they are just deb packages pre compiled for ubuntu based distro's.

There will be 2 header packs, 1 marked all and the other marked header. You need both to build needed headers.

You also need the main image pack as well.

Once downloaded, installing is as easy as double clicking and select install then enter your sudo password.

Removal would be to use synaptic package manager type in the name of the kernel and completely remove, then remember to run

Code: Select all

sudo update-grub2
to update grub boot menu.

YES, Mint 11 must be installed first.
