Wifi USB Adapter stops working intermittently

[AndyOpie150]

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;

Code: [Select]

rfkill block wifi0

or

Code: [Select]

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.

 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

[AndyOpie150]

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.

[AndyOpie150]

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;

Code: [Select]

sudo rfkill unblock all


[Colin23erk]

Yes it has the FN+F9 and an LED for Wireless
I had noticed that the LED comes on at startup and stays on whatever I do with the FN+F9 keys

This is the output when I try iwconfig ----FN+F9----iwconfig ----FN+F9---

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.

Give me one more output. Type in this:

Code: [Select]

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;

Code: [Select]

sudo apt-get update && sudo apt-get install rfkill
rfkill list


[Colin23erk]

No need to kill the internal WiFi "Its already dead Jim" LOL.
Here is output from Samsung

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?

Try this for the doggle;

Then reboot.

Post the output of this for the internal wireless;

Code: [Select]

lspci -nnk | grep -i net

Should be able to get one or both to work.

[AndyOpie150]

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

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.
