Intel wireless 3160 ac unsable/disconnection

[Andrea Isoni]

I am experiencing problems with Intel wireless 3160 ac on Ubuntu 14.04. At the moment I am using the kernel 3.13.0-37_3.13.0-37.64+iwlltr0001 from: http://people.canonical.com/~sforshee/iwl-ltr/trusty/ and the firmware iwlwifi-3160-9-ucode.
I am usually observing the wireless behaviour through wavemon and the number of invalid misc increases continuously when I am surfing on the internet. Occasionally the pages stop loading and the the number of mac retries increases. After around of 1Gb downloaded (or less) I always losing the connection, the network-manager has to be restarted but the wireless connection cannot be recovered until I reboot. Usually the bitrate is around 1-2Mbit/s.
I have tried already the kernel 3.16.3 but the problem is even worse.

The new kernel does not boot on my computer (blank screen).

[Joseph Salisbury (jsalisbury)]

Can you please try the latest -rc3 kernel:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.18-rc3-vivid/

[Andrea Isoni (ciccibolli86)]

My computer just breaks down. I tried different updates and the kernel then a black screen then I rebooted then only the toshiba start screen appears. I can only access the bios so I suspect the hard drive is gone.

Similar problem with same wifi adapter - Intel Corporation Wireless 3160 (rev 93).

After boot wifi works, after few minutes without reason internet stops to work, but connection is not lost.

[Constantinos (csgeorgiades)]

Also similar problem with Intel Corporation Wireless 3160 (rev 93).
After boot wifi works, after few minutes (time vary) connection is lost.
Also after the connection is lost i can not see the access point. Enabling/disabling network (sometimes) makes the AP visible again. But again after i connect connection is lost after a while.
