tp-link ac600 disconnects for unknown reason, then causes kernel to freeze when unpluggin. #7

Open zhengwy888 opened 8 years ago

zhengwy888 commented 8 years ago

ubuntu 14.04, cpu is intel. I am using TP-link AC600. and the forked driver from https://github.com/Myria-de/mt7610u_wifi_sta_v3002_dpo_20130916

The network card would occasionally go disconnect. and upon unplugging it, ubuntu kernel would freeze. There are some messages in syslog, which I couldn't decipher, so looking for some expertise in figuring out what is the issue here. Thanks in advance.

Then the internet goes completely out.

tohava commented 8 years ago

I don't know what is causing the disconnections, but I managed to fix the problem that causes kernel error. Thus, instead of rebooting, you can do rmmod, disconnect, and reconnect the wifi card.

Here is the commit containing the fix, good luck.

https://github.com/tohava/mt7610u_wifi_sta_v3002_dpo_20130916/commit/0de1c98aab902f42c1d4734fb173dde6150ffe6f

p.s. Do you have any idea how do I let others know about this change?

ZelphirKaltstahl commented 7 years ago

@tohava I've got no idea how to let others know, but for me a very similar and possibly related problem occurs: Freeze when plugging the USB device in. (T2UH AC600) Is your change already merged into master?

tohava commented 7 years ago

@ZelphirKaltstahl Yes, it is the pull request linked above, "Fix page fault that occurs when we call..."
