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.

  • 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. ;-) – LAFK says Reinstate Monica 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.

  • If your answer is essentially a referral to another question, it would be better to flag this question as a duplicate of the other (with the [flag] button below this one). – David Foerster Apr 29 '15 at 10:59
  • 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
