Wireless adapter Intel 7260

I am using JetPack R21 on my tegra TK1 and I am trying to get WiFi working. I have the intel 7260 wireless pcie adapter installed.

I created a wireless connection for the device.

lspci shows:

00:00.0 PCI bridge: …
01:00.0 Network Controller: Intel Corporation Wireless 7260 (rev 73)
02:00.0 PCI bridge: … TegraK1 PCIe Bridge (rev a1)
03:00.0 Ethernet Controller: Realtek …

sudo lspci -vvv -s 01:00.0 shows:

Kernel modules: iwlwifi

it seems the driver is available, detected, and bound to the hardware

The network manager gui does not show that WiFi is enabled and will not scan for an AP. I hope I don’t have to go all of the way back to the Grinch kernel.

Any help would be appreciated.

Does the “+” button on “sudo nm-connection-editor”, which is for adding connections, give you an option to add WiFi?

Does anyone know if the Intel 7260 requires extra firmware?

sudo nm-connection-editor brings up the same UI as pressing the network GUI on the top banner. It does not have a + button, but does have an add button.

I have added a wifi connection for this adapter.

On the network dropdown, it has all of the wired connection stuff like Enable Networking but no Wi-Fi Networks and no Enable Wi-Fi.

Connection Information shows the wired connection.

I was reading other queries for different things and found someone who was asked to:

dmesg | grep iwl

result is:
request for firmware file 'iwlwifi-7260-7.ucode failed
no suitable firmware found!

So, it seems the firmware is not available.

I downloaded the firmware for kernel 3.10 and copied it to /lib/firmware

uname -r yields: 3.10.40-…

So I think I got the correct firmware file.

When I try to run firefox, i get a message firefox crashed. There is a lengthy crash report, couldn’t tell much from it.

if I dmesg | grep iwl yields:
loaded firmware version 222.1.7.0 op_mode iwlmvm
Detected Inter® Dual Band Wireless AC 7260, REV=0x144

I can copy the entire information if it would be useful.

I downloaded Chromium and it works just fine.
