ASUS X550C wifi

Question

There is a lot of similar problems, but this one is a bit different. I have no phy0: Wireless LAN

Ubuntu: 14.04.1

sudo rfkill list all

0: asus-wlan: Wireless LAN
    Soft blocked: no
    Hard blocked: no
1: asus-bluetooth: Bluetooth
    Soft blocked: no
    Hard blocked: no

When I plug in an external wifi usb adapter from TP-Link, I got also

2: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no

and my wifi works. But I dont know why my wifi doesnt work without this adapter.

I suspect that your internal wireless is this: "0: asus-wlan: Wireless LAN" It may be that it lacks a driver or that the driver isn't loading. Please edit your question to add details of your internal device from: lspci -nn | grep 0280 Thanks. — chili555, Dec 21 '14 at 14:49

Your device does indeed lack a driver. Please get a temporary internet connection and open a terminal:

sudo apt-get update
sudo apt-get install linux-headers-generic build-essential git
git clone https://github.com/lwfinger/mt7630.git
cd mt7630
make
sudo make install
sudo modprobe rt2800pci

Let us know about any errors or if you get stuck. We will probably have one additional step.

Unfortunately, on my Ubuntu 14.10 system, I also get the 'Unknown symbol in module, or unknown parameter' error. Consulting the github page shows this comment from the developer:

since I don't have time and hardware so please don't expect any improvement.

I regret that I know of no way currently to get this device working correctly. For now, I suggest you continue to use the USB.

I got problem with last command.

Please try a reboot and see if it loaded automatically: lsmod | grep rt2 – chili555 Dec 21 '14 at 19:55
lsmod | grep rt2

Now detach the USB and see if the internal is working: iwconfig. – chili555 Dec 21 '14 at 20:06
iwconfig eth0 no wireless extensions.
lo no wireless extensions.

Look for clues: dmesg | grep rt2. It may be lengthy, so paste it here and give us the link in your response: http://paste.ubuntu.com – chili555 Dec 21 '14 at 20:50

May I assume that the reboot was with the USB and therefore its possibly conflicting drivers removed? – chili555 Dec 22 '14 at 13:28
I unplugged USB and then rebooted – Martin Kravec Dec 24 '14 at 09:20
Please see my edit above. – chili555 Dec 24 '14 at 14:14
