NOTHING HAPPENS. I can't see the list with that command anymore, it seems.

What didn't work?

After the last update for Ubuntu I installed (around two days ago) as usual I had to re-install the drivers, but my system freezes everytime I try. The problem is similar to the one that #48 got, but the solution proposed by @neurobin there did not work for me. I used an old release until now (I remember it being around one-year old), but switching to the new one changed nothing.

What did you try?

See above.

Hi, try this steps:

sudo make clean
sudo make
sudo ./install

[kv3tak]

I have the same issue. After running ./install, the system freezes.

sudo make clean
sudo make
sudo ./install

didn't helped :(

Edit: make generates some errors, that I haven't seen before.

I recommend you delete the folder and clone again.

[kv3tak]

Still the same results...

[saurabh-mhaisekar]

Try this: sudo ./uninstall sudo apt-get clean sudo apt-get update sudo ./install

If system still freezes, output of the following command would be helpful: dpkg -l | grep ^..r

Meantime you would like to use drivers temparily. sudo ./test

PS: I am curious if you could run module temparily.

[TrevorG]

Hello. Some problem here. For me, ./test also freezed. However, I have created some sort of solution:

1) I have decided to fix GCC warning about incompatible pointer types first. After investigating /usr/src/linux-headers-4.4.0-83/include/net/mac80211.h (I was looking for ampdu_action, which led me to the ieee80211_ops struct defined in that file) I have changed source code in this repository. git diff output below:

2) After that, I have executed sudo modprobe rt2800pci. Running sudo ./test before that, resulted in failure. 3) Finally, I have executed sudo ./test and right now I am writing this comment using my WiFi.

I am not sure if this is a correct solution - my linux-fu is not strong enough;)

[TrevorG]

Sure, but the day after tomorrow at the earliest

[asereze]

@glats

Hi, try this steps:

sudo make clean sudo make sudo ./install

That's what @neurobin suggested in #48, but it doesn't work for me.

@SaurabhMhaisekar

Try this: sudo ./uninstall sudo apt-get clean sudo apt-get update sudo ./install

Doesn't work as well

If system still freezes, output of the following command would be helpful: dpkg -l | grep ^..r

I get nothing. Like with "rfkill list" the command doesn't seem to work anymore.

Meantime you would like to use drivers temparily. sudo ./test

If I try the system freezes like during an installation.

[PeaceMaker503]

@TrevorG Your solution seems to work thank you. At least I had the same problem, I applied your diff and reinstalled as suggested in #48 and it is now functional. (Ubuntu 16.04)

[ghost]

Same problem here.

@TrevorG: Did not work for me. Even with this patch, when the network manager tries to establish the connection with the AP, the system freezes because of a kernel oops. From what i see the stack trace on the screen:

rt2800_ampdu_action eventually results in a page fault at location ffffffffffffffd8

I just looked at the kernel header and it seems the kernel interface 80211blahblah_ampdu_action has changed in a way braking this driver.

[Sineth-N]

same issue here, I have explicitly removed the file mt7630 in /var/lib/dkms then make an sudo ./uninstall and next sudo make clean later sudo make dkms still can't get this driver up. on top of that I cannot apply the patch that @TrevorG suggested due to some error in modprobe. I'm also getting the exact same error as @kv3tak when make is executed. Highly appreciate if anyone can help us in this matter Thanks. UPDATE: Once the sudo make dkms is executed I restarted the machine without running the sudo ./install, In the login screen I can see my home wifi SSID and if I proceed without physically turning off the wifi using HW button I run into a system freeze. Later if I physically turn on wifi the machine tries to connect to the wifi but again the system freezes.

UPDATE Appllied the diff in the way @LinuxSDA said and got it working.. Thanks all !!

[kennethmervin01]

same here after the update to 4.4.0-83-generic... please help

[kennethmervin01]

It's working just followed @TrevorG changes to rt2x00/rt2800lib.c and rt2x00/rt2800lib.h

First unsinstall the driver

sudo ./uninstall
make clean

Then change the rt2x00/rt2800lib.c and rt2x00/rt2800lib.h like @TrevorG told then

sudo ./install

[LinuxSDA]

It's working. Thanks a lot @TrevorG.

Those who still have problem. Here are simpler instructions:

• Go to MT7630E-release/rt2x00 folder.

• Open rt2800lib.c in Gedit and search if LINUX_VERSION_CODE >= KERNEL_VERSION(4, 6, 0) replace it with if LINUX_VERSION_CODE >= KERNEL_VERSION(4, 4, 0) for the 2 matches.

• Open rt2800lib.h and search if LINUX_VERSION_CODE >= KERNEL_VERSION(4, 6, 0) replace it with if LINUX_VERSION_CODE >= KERNEL_VERSION(4, 4, 0) for the 1 match.

Now, you can install the drivers:

• sudo ./uninstall

• make clean

• make

• sudo ./install

[asereze]

@LinuxSDA it worked! Thank you very much!

[TrevorG]

Well, it seems that someone has pulled some changes from kernel 4.6.0 to linux-headers-4.4.0-83. With change in definition of ampdu_action among the others. All as fine in linux-headers-4.4.0-81.

Patch presented by me is only a quick hack and such change should not be pulled into the repository, IMHO, as it will create problems for users building with linux headers pre-4.4.0-83. Unfortunately, I have no idea how to write correct patch. This #if should check against "ABI number" (which is something Ubuntu-specific AFAIU) and I have no idea how to check it.

Feel free to create better solution;)

[a-sync]

@TrevorG, @LinuxSDA thanks, can confirm it works!

UTS_UBUNTU_RELEASE_ABI >= 83 could be used to determine if this should be applied for 4.4.0, but only for ubuntu afaik

[jamoreno146]

Thank you so much @LinuxSDA! I experienced this problem after two clean installations, now I solved the problem.

[htcoder]

74 The solution suggested by @LinuxSDA doesn't work for me

[tran184]

same problem with kernel 4.10.0-27

[neurobin]

@tran184 This issue is exclusively related to kernel 4.4.0-83, please open another issue with more information.

[asereze]

With the last update (distributed today) the problem is back again, and this time the method suggested by @LinuxSDA didn't work.

Also is there a good reason why is this driver still not supported by Linux after all this time? Why do we need to reinstall a patch for almost every update? It's absurd.

[rjy7wb]

Played around with it, error only happens when trying to connect to a network.

before installing, if you delete your saved networks you will be able to complete the installation process, but if you try to join a network it will still freeze.

[hnovillo]

@TrevorG Gracias a tu post pude solucionar mi problema!

1. Verifiqué la versión de mi kernel con uname -r. La cual resultó ser 4.4.0-97-generic.
2. Realicé los cambios en ambos archivos, ejecuté los pasos que indicaste, y luego con sudo ./install de inmediato comenzó a funcionar mi wifi.

Sos un Genio!!! Mil Gracias!!!

[ruifm]

Thanks @LinuxSDA, worked like a charm for me (4.4.0-97). Couldn't be happier!

[ash0904]

System freezes every time when trying to connect to a access point. (same problem as @htcoder ) Tried all the above solutions but none worked. What should I do ?

[deeperlearner]

@ash0904 Do not expect this card will work well. Change another wifi card.
