TP-WN727N not working Ubuntu 14.04

[shahin4]

Hello, during live USB my adapter worked fine, during installation my adapter also worked fine, but after installation, my adapter did not work.

I've tried various things;

sudo apt-get update
sudo apt-get install linux-backports-modules-wireless-generic

But received an error saying: Cannot find packet linux-backports-modules-wireless-generic

Also tried;

echo 'install rt2800usb modprobe --ignore-install rt2800usb ; /bin/echo "148f 5370" > /sys/bus/usb/drivers/rt2800usb/new_id' | sudo tee /etc/modprobe.d/rt2800usb.conf 
sudo modprobe -v rt2800usb

Nothing happens

Also tried;

sudo rfkill unblock all
rfkill list

0: phy0: Wireless LAN
soft blocked: no
hard blocked: no
2: brcmwl-0: Wireless LAN
soft blocked: no
hard blocked: yes
5: phy4: Wireless LAN
soft blocked: no
hard blocked: no

phy4 is TP-WN727N

My adapter does not have a hard on/off button on it.

Any fixes for this?

onboard wifi adapter works, but I want my TP 150Mbps adapter to work..

Update:

Also when I click on the wireless icon top-right of the screen, I can see two adapters;
When I click on the Wireless On/Off button on my laptop, both adapter are turned off/on, didn't work first.
Will restart and see if it still works

Update 2:

After restarting, it still works, going to hard-remove the internal Wireless adapter, because it switches between them. Also have no use of the internal one anymore. Less power consumption without it.

Update 3:

I removed the built-in wireless LAN module. TP adapter still works, and no further problems

Hi,

please show the outputs of:

uname -a
lspci -nnk | grep -iA2 net
lsusb
lsmod
iwconfig

You should be able to deactivate the internal (Broadcom?) card in your BIOS.

Hi,

I tried disconnecting the integrated lan card and still not working ... With a similar card (TL-WN722N) works perfectly. It may be that the new is USB 3.0? I tried on all USB ports (2.0 and 3.0) on my PC and I get no results.

Since yours is an entirely different device, I suggest you start your own new thread.

No, my product is the same (TP LINK TL-WN727N), the WN722N is my old network card.

My apologies. Would you like to work on the 727 and put the 722 aside so there is no conflict?

I tried disconnecting the integrated lan card and still not working

And you have an internal card, too, in addition to the two USBs?

With a similar card (TL-WN722N) works perfectly.

Then why do you need the 722?

I may be confused.

By the way, I'd rather create time travel and world peace than get this beauty working:

Please help me understand.

It's okay, man.

The 722 is from a friend and the 727 is mine.

I have a integrated lan card in the motherboard (ethernet).

The ethernet works fine.

The USB 722 works fine.

The USB 727 do not work fine. Appears in lsusb but does not detect any network, like a usb memory.

I tried the three individually but give the same result.

Thanks for a lot

[chili555]

I am less confused now. Please detach the 722, reboot with the 727 inserted and run and post:

rfkill list all
lsusb
uname -r

If you need the 722 to post, then run these commands before you insert the 722:

rfkill list all > wifi.txt
lsusb >> wifi.txt
uname -r >> wifi.txt

Find the file wifi.txt in your user directory, connect and then paste the result here.

I am afraid this is what we're dealing with; a nightmare:

We'll do our best.

There is one known working driver for this device: http://ubuntuforums.org/showthread.php?t=2206873 Unfortunately, it doesn't compile in Ubuntu 14.04. At this time, I know of no other driver to try aside from the tricky and deaded ndiswrapper. Do you have Windows XP inf and sys files?

You might email Mediatek and ask for a solution.
