Cannot connect to web/find wireless networks

[_powerplay]

I just partitioned my Computer so that I can boot with Ubuntu or Windows. The installation process was fine but when I click on the wireless sign (or triangle I guess), the "view wireless networks" is greyed out and I cannot click on it. I tried manually installing my connection but that did not work either.

I found my Wireless driver which is D-Link DWA-525 and I tried running some commands I found like...

Sudo lsmod | D-Link DWA-525
Sudo apt-get install Wireless-tools
lspci | grep Network

These were just some commands I read would help but they did nothing.

I put NetworkMananger and NetworkManager Applet on my USB but they would not open in Ubuntu.

I downloaded my wireless driver, put it on my USB and tried to install in Ubuntu and it would not work.

I just wanted to state that I have been trying very hard to figure this out and I still am completely clueless as to how I can get internet running in Ubuntu. Very frustrating.

Any help would be GREATLY appreciated.

I will diligently follow instructions if I can figure this out!!!

Let's see what your wireless device actually is. Please open a terminal and run and post the result of these commands.
lspci -nn | grep 0280
uname -rThanks.

Stupid question but is your wireless enabled.
You may have a wireless switch. If not you may have to press the "Fn" key with one of your function keys (F1, F2, F3 etc). You should notice which of the function keys has a wireless symbol on it. The symbols on the function keys are the same colour as the "Fn" key.

When I use those commands, all it told me was this...

3.0.0-12-generic

Which is the Linux that it says that I'm running when I boot Ubuntu. It said nothing about a wireless device.

Should I just un-installl Ubuntu and install 11.04 or something?

I did.

The first hyperlink said that the page did not exist yet and the second hyperlink just takes me to Ralinteck.com

I understand what this is a very basic question for Ubuntu users but I have really been trying on my own to figure this out and cannot come close. Noob questions or not, I really want to start using Ubuntu and Linux OS but I need internet access in order to do this.

If somebody can help me out here, I would really appreciate it.

I had to bump my own thread, instead of making a new one.

I've been their.

I go to the DWA-525 Model (which is my wireless model)

and then I downloaded RT3062PCI/mPCI/CB/PCIe(RT3060/RT3062/RT3562/RT2860/RT2760/RT2890/RT2790) from Ralinteck.com under the Support>Downlods Tab.

I put it on my USB and tried to install it in Ubuntu but I have no idea how to install it and the "README" in the folder does not help.

It's hard for me to grasp how an OS created by people has so many errors (I mean, there's like 5 threads about inability to access internet just on the 1st page alone).

It is so because not all of the developers are wireless developers and most of the commercial companies do not care for compatibility of their cards with linux. Besides, those with successfully working hardware don't come here creating threads only to tell their success stories, else who knows there could be 5 pages of praise before one problem thread, don't you think so? :)

Anyway, your problem is already being handled by chili555 himself - the best guy around here for such problems, so I shouldn't have jumped in. But since he seems to be away for the moment and you seem a bit impatient, may I dare to ask for a few outputs please? Just to confirm you have downloaded the correct driver for your device (your device model no. does not tell what chip it is using). So please post the output of:

lspci -nnk | grep -iA2 net(please note it is 'piping' symbol between -nnk and grep, not a small 'L'. Just copy-paste to avoid mistakes).

If that does not return any outputs, make sure your card is enabled in BIOS and is physically turned On.

That makes complete sense. Sorry my impatience was so blatant last night. I had just spent like 8 hours searching forums and Google trying to figure all of this out and I just ended up frustrated. I guess learning how to operate a new OS when I was used to one for 13 or 14 years might take some time ;)

Anyways, the code you asked me to use returned this...

I put the code you asked me to do on a Notepad doc then put it on my USB, restarted Windows and booted with Ubuntu, opened the Notepad file from my USB and typed the code into the Ubuntu Terminal then copied the returning results onto the same notepad file, restarted my comp and loaded Windows then copied the Ubuntu results onto here. Is there any easier way of doing this? Haha

Thank you very much for your help.

How simple!! Can't be simpler :lolflag:

Kernel driver in use: rt2800pciSo apparently, you have downloaded the correct driver. But I have no idea either what kind of package it is and thus how to install it. It might have been a piece of cake for chili, but since he still seems away, let me try something in the meanwhile. To me, the current driver 2800pci doesn't seem a suitable one. So please try:

sudo modprobe -r rt2800pci
sudo modprobe rt2860sta
rt2860 is a native driver and seems to work with your card. However, I'm not sure if any additional steps are required or if it is the right approach at all. In any case, it is not going to do any harm to the existing status.

If this doesn't work, please post output of:

lsmod
Since this would be a rather long output, please wrap it between
..and.. tags by selecting (only) the pasted output then clicking on the # symbol at the top of edit box in which you write your posts. (it is recommended for all kind of outputs).

To help with your currently downloaded driver installation, I'll need a list of downloaded packages + maybe the readme file too (believe me, it's just 'me' who needs it, simply because I have absolutely no idea so far about their package). If it is a .tar or .gz archive, you'll need to extract it to a folder, then you can simply use ls command to get a listing of the extracted files. For example, if the files are extracted in a folder named "driver" on the desktop, then:

cd Desktop/driver
ls -l ./ > list.txt
will generate a "list.txt" file in the same folder, whose contents you can then copy-paste here to let me know which files are there in the package.

Sorry if I made it sound more complex, but as I said, it's just me.

Hopefully this makes more sense to you than it does to me :confused:

Also sometimes in the Terminal it asks me to put my password in but then it doesn't allow me to type anything in.

PS:
Now a few things about your doubts-


cd Desktop/driver
RESULT: bash: cd: Desktop/driver: No such file or directoryMeans there is no directory named "driver" on your desktop. It was just an example:
For example, if the files are extracted in a folder named "driver" on the desktop, then..
ls -l ./ > list.txt
(no results returned from this command)The ">" symbol 'redirects' the output (which otherwise would appear on the terminal) to a file that you mention after it. So the above command would have created a file named "list.txt" in the directory in which you were (by default your 'home' directory) when you executed this command. That file contains the output of the command.

But anyway, since you were not in the directory in which the driver files were extracted, that file would have nothing useful in it. If the above instructions didn't work for you, we may need to do it right this time to let me know of the contents of the file you have downloaded from realtek's website..


When I click on my wireless button now, about half of the options have disappeared also.I guess this means you have successfully blacklisted rt2800pci and it's a result of that. If so, you won't need to run 7th and 8th commands I copied above from praseodym's post. But it won't hurt running them anyway (it will just result in blacklisting rt2800pci in two places, which is ok).



Also sometimes in the Terminal it asks me to put my password in but then it doesn't allow me to type anything in.Ah, that's the most interesting thing for you to know. Terminal will almost always ask you for your password whenever you run a command with "root" privileges (which is obtained by using sudo, su or gksu before a command). However, if you have supplied it your password recently (within 15 min. I guess), it won't ask for it again.

Now when you see nothing appearing on the terminal while typing your password, it is actually logging each and every key you press, it just doesn't appear on the screen for security purpose. More about sudo:

Hope you are still awake ;). If so, please execute those commands suggested under "please try this first:" and tell us if it helped or not.

You need to be connected to internet (through wired connection of course). If you are, open Software Center and see if those packages (dkms and build-essential) are installed. If they are not, just install them from there.

If you can not connect via cable, just confirm whether those packages are already installed or not (see in Software Center). We can take it from there.
