I just brought a TP-Link WN727N wireless adapter to work on ubuntu since my default wifi has issues. My system is HP-ab030tx. lsusb produces the following result :

Bus 002 Device 002: ID 148f:7601 Ralink Technology, Corp.

So the system recognizes the usb. I have tried following solutions till now.

  1. chili555's first answer from this
  2. Also tried to install rt2800usb using instructions from https://help.ubuntu.com/community/WifiDocs/Device/Tenda_W311M

The problem now is as soon as i plug in the device the light in the device brightens up and the system freezes or undergoes a kernel panick. Tried the same thing on ubuntu 15.10 with the same result. I cannot try new coomands with the usb on now since it freezes everytime. Right now i am on ubuntu 14.04.3 which also has the same problem. I have been on this over a week. Please suggest me a solution. PS : Please let me know if anyone wants to know anything about any commands from my OS.

Your device is covered by default in Ubuntu 15.10. You are probably only missing the firmware. Download and install the firmware with:

sudo apt-get install git
git clone https://github.com/porjo/mt7601
cd mt7601/src/mcu/bin
sudo cp MT7601.bin /lib/firmware/mt7601u.bin

Insert the device and it should be working.

  • Thanks for the quick reply. It worked for 5-10 mins and then kernel panicked again. Does it have anything to do with built in wifi? I switched off the built in wireless by 'sudo ifconfig wlo1 down'

  • I suggest we blacklist the driver for the internal device. Please post: lspci -nnk | grep 0280 -A2

  • Okay. So the output of the command is : 08:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8723BE PCIe Wireless Network Adapter [10ec:b723] DeviceName: Realtek RTL8723BE 802.11b/g/n 1x1Wi-Fi + BT4.0 Combo Adapter Subsystem: Hewlett-Packard Company Device [103c:804c]

  • I then blacklisted the driver rtl8723be in blacklist.conf file but still the laptop froze like before after 10 min.

  • Did you reboot after the blacklist? Any clues in /var/log/syslog? Make a note of the time of the freeze and after a reboot, check the log for what happened just before and at that time. Paste it here and give us the link: paste.ubuntu.com
