My internal Wifi failed to see my Router soon after I started with Linux so I installed a USB dongle I had
The dongle works OK for a while and then I loose my Internet but not the wifi connection . If I disconnect/connect wifi it works ok for a while . There does not appear to be a pattern to when it fails.
It is a Realtek RTL8188CUS 802.11n using WLAN Adaptor driver : rtl8192cu which is also installed in WinXP
I am hoping someone can give me a solution that I can understand preferably using GUI as other than trying to sort the problems I have had I have no need to learn CLI . I just want to do everyday tasks on my computer.
I have searched the Internet and there could be an issue with the Linux Drivers rtl 8192cu for the Realtek Adapter . Unfortunately for me the solutions mostly involve using Command Line . I have tried some but get confused when they are not recognized.
With the many flavors of Linux I am not sure if they all should work in Lite 2 . Also having only a very limited knowledge of CLI its difficult to know if the commands given require me to be in the correct command structure before they will work .
Also the outputs are in such an abbreviated form that needs converted to normal language to know what they mean !!!!

Your Forum profile says you use 1.0.8. Can you please confirm for us what version of Linux Lite you are using? Also, just for the record there won't be a GUI way to install this wifi adapter, if it is not playing ball, the command line is the way to get it going properly.
-
Could you open up the terminal and type in:
lsusb
lspci -nn | grep Network
lsmod
These are three different commands. Hit the enter key after typing in each line.
Then post the output by copying then pasting here.
Put the word code before the output, wrapped in [ ], then at the end put the same thing but with a / between the [ and c.
This is called code wrappers.

Thanks
I have updated my Profile to Lite2 and run the commands -I hope this helps
Thanks for the instructions . I hope I understood them and got it right . An example would have helped me understand

Question.
Have you already typed in a terminal:
sudo su
apt-get update && apt-get dist-upgrade
?
If not, plug computer into the back of the router and do this first. After it's done reboot and see if it will connect properly.
EDIT: You did good!
Could you post the Manufacturer, model number, and year of computer?
-
Hi Thanks for that
I assume you meant me to connect using an Ethernet cable so I could connect to the Internet to download the update .
Am I correct in thinking that the commands are the same as using the upgrade from the Menu .
If so I had done it again yesterday .
Just to say that the WiFi Dongle does connect through the Wifi Router and I can use the internet OK for a while . Then later when I try to go to a different page I get a message saying I am unable to connect .
Network Manager still says I am connected to my WiFi . If I disconnect and reconnect using Network Manager everything works normally immediately until it fails yet again .
I have a different computer that uses the same Router . It has no problems using the Router as did this one before I needed to use the dongle .

Let me do a little bit more research.
I think I might have found a solution/path to a solution.
I'm like a blood hound following a scent.
Please post manufacturer, model number, and year of computer.
-
The doggle is a TP-LINK 150bps wireless N usb adapter, right?
Model number TL-WN72?N. Could you fill in the question mark please.
EDIT: Just to be on the safe side, could you type in a terminal;
sudo su
apt-get install firmware-realtek
-
The Netbook which I had the problem first is an Advent 4211 bought August 2008 is in pieces to repair a broken hinge
This is the output from my Samsung NC110 Netbook which experienced a failure with the USB WiFi dongle this session . The dongle consists of usb connector with a 1/4 inch of black plastic has no name on it . All that is written on it is 802.11n

I'm back. Got to dig some more.
EDIT: Might have to compile the module from the driver found here: http://www.realtek.com/downloads/downloadsView.aspx?Langid=1&PNid=21&PFid=48&Level=5&Conn=4&ProdID=274&DownTypeID=3&GetDown=false&Downloads=true#2292 (http://www.realtek.com/downloads/downloadsView.aspx?Langid=1&PNid=21&PFid=48&Level=5&Conn=4&ProdID=274&DownTypeID=3&GetDown=false&Downloads=true#2292)
Will read up on it more so I can walk you thru it if absolutely necessary (really don't think it is though). Will look for more alternatives.
I'm really starting to think by the output of the lsmod command that a firmware update is needed. Will look into this as well.
-
Try this for the doggle;
sudo apt-get install linux-backports-modules-cw-3.6-precise-generic
Then reboot.
Post the output of this for the internal wireless;
lspci -nnk | grep -i net
sudo lshw -C network
Should be able to get one or both to work.

Ahh! Now where getting somewhere. Let me find the command to kill the internal wireless, but still allow the USB adapter. They are probably conflicting which is causing you problem. Might be the same for your other computer.
Could you post those commands for your other comtputer as well?

No need to kill the internal WiFi "Its already dead Jim" LOL.

Give me one more output. Type in this:
iwconfig
Post for both computers, but don't type in a number in the [ ]'s, just post two different outputs.
EDIT: Look at the last posted output for the Samsung. It shows the PCI device has been asigned and IP address. It is functioning. I think we should be able to get it working with out to much trouble.
Post the output of the last command of the two;
sudo apt-get update && sudo apt-get install rfkill
rfkill list

Pull out the doggle and post the same "iwconfig" output.
What happened to the "rfkill list" comand output? This will show if your wireless pci card is being blocked. If it shows an output then there is a button or key, or setting in the bios, that will turn it on. Seeings how it's a Samsung this is highly probable.
Edit: Press the FN + F9 keys to turn on wireless.

If after you press the
FN + F9 keys and the LED for wireless stays on, then all you need to do now is connect/configure your wireless.
In the task bar you should have a Network icon. Right click to make sure you have a checkmark next to "enable networking" and "enable wireless". If yes, then left click the same icon and select your network. Type in network password when the pop up window appears.
If not, let me know what you see/don't see and type in;

As you can see, you have nothing blocking your pci wireless card from working.
You should now only have to left click on the network icon and select your network.
If your network is not displayed, does it show others? If so, you will need to configure your network manually.
Let me know what is going on/what you see. Please don't leave out anything, let me know exactly what you see.
PS: You shouldn't need to run rfkill commands anymore.
EDIT: Almost forgot. Turn router off and unplug from power. Then turn computer off. Wait 5 minutes.
Power up router and let it fully reboot, then turn on computer. See if it will now show you network in the network manager.

Hi Andy
I am not sure what your line of thought is . WiFi works OK
The original problem was that the USB WiFi adapter can connect to the internet normally via the router but after a while the internet is lost but the connection to the Router is still there .
The problem does not happen with the internal WiFi connection
-
OK. I just thought you wanted the Wireless to work. The internal is fully capable of WPA2 security. Why would you want to use the USB doggle if the internal will give the same results?
Anyway. If you want to use the USB doggle then you need to kill the internal.
Type in;
rfkill block wifi0
or
ifdown wifi0
What's the story on the other computer? Do you still need to eventually get the wireless working on it? Unless you gave it away. Then I guess there would be no need.
-
Sorry
The problem happened when my Advent PC's Internal WiFi stopped connecting to my router so I used the USB WiFi adapter and although it connected successfully via the Router the Internet kept dropping out .
To see if it was a problem with the Adapter I tried it in the Samsung PC and found it was exactly the same .
At the moment the Advent is not serviceable so I have been using the Samsung to try and find a solution that will work in both PCs
-
Did it work?

colin@colin-NC110:~$ ifdown wifi0

As it failed I tried

The Advent gets used when my friend comes so I would like it to be able to connect to You Tube
-
Hello!
Am I just being ignorant, or should wifi0 be wl0 or wlan0 instead?

-
LOL. No it should be wlan0.
Thanks for catching my brain dead mistake.
Colin23erk: Replace wifi0 with wlan0 in the code. Sorry for the mistake.
EDIT: Looking at the outputs to the Advent; the code should be the same for it to. Don't know why I was thinking it was wifi0 (I help out at to many linux forum sites).

I think we need to concentrate on the other machine instead of the Samsung with the already great WiFi connection.
Try the commands on the Advent, as thats the one you need to get the WiFi working on.

OK I was hoping to sort out the problem while the Advent is away and possibly help someone else in the future .
I have noticed a difference with the adapter between Linux (adapter light stays on ) and Win7 ( light flashes)
Thanks for all the effort you put in trying to solve it .

Sorry about that. Didn't see the last output clearly. Not enough sleep last night due to installing Linux Lite on another computer, but only had phones throttled 3G signal 25KB/s to update-took forever).
If you want you could try:
The kill command, switching wlan0 with phy0.
Again sorry for not seeing the last output clearly.

Hello!
Found this helpfile in rfkill:
rob@N4RPS-D630-L:~$ rfkill --help
Usage: rfkill [options] command
Options:
--version show version (0.5-1ubuntu1 (Ubuntu))
Commands:
help
event
list [IDENTIFIER]
block IDENTIFIER
unblock IDENTIFIER
where IDENTIFIER is the index no. of an rfkill switch or one of:
<idx> all wifi wlan bluetooth uwb ultrawideband wimax wwan gps fm nfc
Apparently, 'wlan0' is not supported. Given what the help file says, I must stand corrected about wifi as a legal parameter for this command. Additionally, I'd run this rfkill command BEFORE inserting the USB adapter, so you don't kill IT, TOO.
As for the 'ifdown' command, try 'sudo' in front of it. Whenever you see 'Permission denied', it's probably because it's a 'super user only ' command...

Hi
Loosing Hope with solving this --each step forward just presents a new problem to solve !
I have found out what the identifier is for rfkill its the devices number as shown with ( rfkill list )
root@colin-NC110:/home/colin# rfkill list
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
1: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
2: samsung-wlan: Wireless LAN
Soft blocked: no
Hard blocked: no
3: samsung-bluetooth: Bluetooth
Soft blocked: no
Hard blocked: no
4: phy1: Wireless LAN
Soft blocked: yes
Hard blocked: no
root@colin-NC110:/home/colin# rfkill unblock 1
root@colin-NC110:/home/colin# rfkill unblock 4
root@colin-NC110:/home/colin#
I blocked 1 before I connected the dongle to find I still had no WiF
The next problem is that both phy1 and phy0 are both blocked
In the output above item 1 that is shown as not blocked is also blocked for use as well as Item 4 which is shown as soft blocked
I could not unblock 1 (rfkill unblock 1) directly
I only got WiFi back when unblocking 4 (rfkill unblock 4) which unlocked 1 and 4
Where do I go now ??????

Time to do some more research on my part. Will post if I find out anything. It's got to be something simple that I'm missing.
