I am trying to assess hardware issues in installing Ubuntu 16.04 desktop version on a HP x360 laptop with Intel Dual Band Wireless AC3165, before doing the actual install. When booted from live USB, wifi does not seem to work. The adapter has been reported to work with 15.10 at How can I install Intel Dual Band Wireless-AC 3165 drivers?, where the workaround suggests using iwlwifi driver for 7265D version 13-ucode. Further, https://wireless.wiki.kernel.org/en/users/Drivers/iwlwifi suggests that the wireless adapter should work directly with Linux kernel 4.1 onwards, as also Wireless card firmware (Intel 3165 iwlwifi) only available for kernel 4.1+: any options for kernel 3.19?, which means it should work with 16.04. How should I get it working? My hardware info follows:

  • Ah, well, yes, i have indeed reported that link in my question. However this and all other solutions require a reboot phase where the changes made in a LiveCD environment are unfortunately lost. – tagMacher May 18 '16 at 18:54
