This question already has an answer here:

I am new to Ubuntu world since I've been using it for near a year or so. Software is great, but I have some hardware issues.

Along with Ubuntu 14.04 come kernel witch was ok – some minor issues : bluetooth and wireless were constantly turning on after reboot - fine. With Ubuntu 14.10 and kernel 3.16 things slightly improve on bluetooth side – good. With 3.18.8 things got back they wore -bad. But then I installed kernel 3.19 and things got worse. Now my ethernet connection have problem. I can start it, load a page, then it turns off, then on..... I can't use old kernel forever and newer kernels are worse than the old ones.

My laptop is Lenovo y580 with: Qualcomm Atheros AR8161 Gigabit Ethernet (rev 08) Intel Corporation Centrino Wireless-N 2200 (rev c4).

How do I solve this problems, no software could help (blueman,windows wireless drivers, network tools)? Can I download a single driver for each device if some of the issues come back with newer kernels? Should I report this problems and where? I understand it's not an easy task.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • What logs say? Take a look at /var/log/ files and see what gets written and where. ls -tl /var/log/ | less should give you logs sorted from most recently touched down. Take few first and see what your system tells you. I'd go with dmesg and syslog, off my head. Oh, dmesg should output something too. In short: more data required. ;-) – LIttle Ancient Forest Kami Mar 10 '15 at 17:04
  • Thank you for the reply, I guess I wasn't clear in my question, sorry. Didn't understand really your answer. As I said I am a noob. Is it possible to download/extract a single driver for my device from the working kernel eg: 3.16? This way I can use it later on some newer Ubuntu releases and implement it in some newer kernels. – VRR Mar 12 '15 at 13:57

Never mind. I got the answer here: ALX on AR8191 does not appear to be working 15.04.

  • It was one of my first questions and didn't know how this site is functioning. I have resolved it and don't believe it can help anyone further so I answered superficial just to close. – VRR Apr 29 '15 at 13:32
