Help with new System76 laptop


have bought 2 system76 desktops in the past and never had a problem installing Linux Mint. I recently bought a system76 Lemur lap top with 867Mbps + bluetooth
https://system76.com/cart/configure/lemu6
Mint 17 will not recognize the wireless hardware in there. Ubuntu + Cinnamon kind of sucks.

Any help is appreciated.

Thanks.

Hi...

If you would, please open a terminal and post the results of these commands...

Code:
lspci -nnk | grep -i net -A2
Code:
lsmod
Code:
iwconfig
Code:
rfkill list
This should give more details of the wireless adapter your system is using.

Regards...

Hi...

From what I see below, your adapter is not only recognized but you're logged into a network...

Code:
02:00.0 Network controller [0280]: Intel Corporation Wireless 8260 [8086:24f3] (rev 3a)
	Subsystem: Intel Corporation Device [8086:1010]
	Kernel driver in use: iwlwifi
Code:
iwlwifi               200704  1 iwlmvm

          Mode:Managed  Frequency:5.745 GHz  Access Point: 74:D0:2B:89:1D:2C   
          Bit Rate=780 Mb/s   Tx-Power=22 dBm

          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:114   Missed beacon:0
However, your bluetooth is soft blocked for some reason. So, out of curiosity, does executing the following command restore your internet connectivity? Please confirm that all entries remain unblocked.

Code:
rfkill unblock all
Also, what do you see when you bring up a browser?

Regards...

I'm sorry. I posted that from the Ubuntu system which can read it. Here is the output from the Linux Mint live USB.
