Wireless-AC capabilities

I installed VyOS Rolling version on a ProtectLI FW6B and it works great! I installed an Intel 7260.MWG.R wireless AC card but VyOS does not see it. A live CD for Debian 9 does see the card correctly. After some research, it looks like the linux kernel version is the issue. Will VyOS be updated to support newer wifi cards? Can I manually install the wifi driver?

uname -r on debian 9 shows 4.09.0-8-amd64
uname -r on VyOS shows 3.13.11-1amd64-vyos

Intel recommends kernel version 4.1+

you want to try 1.2 from here VyOS Community
let us know how it goes

Hi syncer,

Thanks! I will try tonight and let you know.

add system image VyOS Community
uname -r is now 4.14.65-amd64-vyos

‘show interfaces’ does not have a new interface

wget iwlwifi-7260-17.ucode - kernel/git/firmware/linux-firmware.git - Repository of firmware blobs for use with the Linux kernel

‘show interfaces’ still does not have a new interface :frowning:

Problem with wireless cards is as always: firmware.

Can you pleas einstall this file into /lib/firmware of your VyOS router and reboot:

Hi c-po,

In my post above, I already downloaded that file using wget, copied it to /lib/firmware and rebooted. However, I still have no wifi interface. Am I missing a step?

What does dmesg say after your reboot? Is the firmware file found?

I just ran the below right now.

sudo ls -l /lib/firmware | grep 7260
-rw-r–r-- 1 root root 6968233 Oct 23 07:01 iwlwifi-7260-17.ucode

-rw-r–r-- 1 root root 679380 Jun 15 2014 iwlwifi-7260-9.ucode
vyos@vyos:~$ reboot

vyos@vyos:~$ dmesg | grep iwlwifi
[ 9.061736] iwlwifi 0000:07:00.0: uCode file size 6968233 does not match expected size

The firmware file has only one Mb in the Git repo. Yours is much bigger. Please ensure you have the correct one!

I went to the below link in my browser and do see the listed size as 1049340

I think I was using the wrong url for wget. When I select iwlwifi-3160-17.ucode it opens another page with another link called plain. This link provides a 1.2MB file. I was downloading the iwlwifi-3160-17.ucode page instead of the plain text file.

I will try this link tonight and let you know the results.

Success! Thank you for your help.

I tried to post my steps but it will not allow me to post links anymore.

Update to 1.2.0-rc3
add system image URL

Download driver.
Use the firmware link provided by C-po
right click the [plain] hyperlink and copy the link address
wget URL
sudo cp iwlwifi-7260-17.ucode /lib/firmware

Show interfaces

wlan0 is now listed
