I'm trying to compile this driver for the TP-Link T2U usb WLAN adapter on Ubuntu 16.10. Trying to perform make command I get the following error:

    /home/iks/src/mt7610u_wifi_sta_v3002_dpo_20130916/include/cfg80211.h:35:49: error: ‘IEEE80211_NUM_BANDS’ undeclared here (not in a function)
  struct ieee80211_supported_band Cfg80211_bands[IEEE80211_NUM_BANDS];

The solution from here contains exactly the same installation manual as in the repository and therefore doesn't help.

Could someone help me to solve this?

The circa-2013 driver file is too old for your 4.8.0-xx kernel, try this instead:

git clone https://github.com/ulli-kroll/mt7610u.git
cd mt7610u
make
sudo cp firmware/*  /lib/firmware
sudo insmod mt7610u.ko

Please tell us how it went as we will have additional steps.

  • Until make install everything was perfect. Install results in 'code No rule to make target 'install'. Stop. and modprobe: 'code FATAL: Module mt7610 not found in directory /lib/modules/4.8.0-32-generic' But somehow I see the MediaTek Wi-Fi device in the Network Manager, though it says "Device not ready" and its grayed out. – Ivan Kuznetsov Dec 28 '16 at 17:51
  • Please see my edit above in a few minutes. – chili555 Dec 28 '16 at 23:00
  • Here is the resultinsmod: ERROR: could not load module mt7610u: No such file or directory – Ivan Kuznetsov Dec 29 '16 at 07:50
  • Were you in the correct directory when you did the command: cd ~/mt7610u Check if the file is there: ls Now try to load it: sudo insmod mt7610u.ko – chili555 Dec 29 '16 at 14:47
  • ok, the problem was in the *.ko extension, I forgot to add it, I'm sorry. Now the insmod went without any output. – Ivan Kuznetsov Dec 29 '16 at 16:08
  • Awesome! And now do you have available connections in Network Manager? – chili555 Dec 29 '16 at 17:31
  • Unfortunately no. It appeared in Network Manager as Wifi Network(MediaTek WiFi) but it says "device not ready" and its grayed out. No possibility to see or scan networks. – Ivan Kuznetsov Dec 29 '16 at 19:34
  • May we see a log? cat /var/log/syslog | grep -e mt76 -e wl As the output may be lengthy, paste the result here and give us the link: http://paste.ubuntu.com – chili555 Dec 29 '16 at 21:42
  • Sure log . wlp3s0 is a built-in wlan adapter – Ivan Kuznetsov Dec 29 '16 at 21:55
  • I am quite confident that two different devices attempting to connect at the same time conflict. Why are you trying to activate the tricky and work-in-progress mt7610u instead of the usually reliable Broadcom?? – chili555 Dec 29 '16 at 22:12
  • The reason is 5Ghz band. It is that much crowded on 2.4 around that the wireless connection is almost not working. – Ivan Kuznetsov Dec 29 '16 at 23:09
  • Does the command: sudo iwlist channel` confirm that mt7610u is capble of 5 ghz? If so, before we proceed further, we out to blacklist the driver for the internal. – chili555 Dec 30 '16 at 02:48
  • I've checked it, yes, it has 5GHz support. Btw, thank you very much for helping me. – Ivan Kuznetsov Dec 30 '16 at 09:30
  • I suggest that you blacklist the driver for the internal device; it can be easily reversed if needed. echo "blacklist wl" | sudo tee -a /etc/modprobe.d/blacklist.conf Reboot and let us see another log as above. – chili555 Dec 30 '16 at 13:51
  • Everything goes well... until I try to run insmod... then I get the following error: "insmod: ERROR: could not insert module mt7610u.ko: Unknown symbol in module"... Any ideas on how to fix it?

    Kernel: 4.13.0-16-generic

  • @danielfranca I don’t believe there is any way to get this to work on any kernel version that is not now (12/2017) end of life. Sorry. – chili555 Dec 20 '17 at 13:09
  • I have this: insmod: ERROR: could not insert module mt7610u.ko: Unknown symbol in module – MarkSkayff Mar 11 '18 at 23:08
  • @MarkSkayff Please see my comment just above yours. – chili555 Mar 11 '18 at 23:09
  • whats the use of a solution that no longer applies. Maybe there should be a linux kernel marker. Like worked with ... – JackGrinningCat Dec 14 '18 at 15:05
  • @JackGrinningCat My answer clearly refers to kernel version 4.8. If yoyrs is newer, then this is not for you. In any event, I doubt that there is ANY solution to get an mt7610u working in 4.15 and newer. – chili555 Dec 14 '18 at 15:59
