No wireless Intel Dual Band Wireless-AC 8260 on RHEL 6.5


Iím trying to get a Linux seat prepared for a user and Iím running into a dead end. I was able to install a driver and get the Ethernet adapter to work. Havenít tried setting up sound yet, so as of now it doesnít have sound. The main problem Iím having is with wireless. This laptop has the Intel Dual Band Wireless-AC 8260 802.11 a/b/g/n/ac (2x2) WiFi and Bluetooth 4.2 combo (vPro) wireless adapter. It is supposed to work with Intelís iwlwifi kernel module so there are no drivers to install. The kernel drivers support all of the Intel wireless adapters up to but not including the AC 8260. The AC 7260 is the last supported module since RHEL has an older kernel. I ran lspci Ėnn to list all the pci devices and it lists the wireless as ď00:16.0 Communication controller [0780]: Intel Corporation Device [8086:9d3a] (rev 21)Ē. If I run ifconfig -a it lists the Ethernet adapter, the PAN adapter for Bluetooth networking and the loopback address.

I downloaded the firmware for the adapter and copied it to /lib/firmware and then ran modprobe iwlwifi to redetect, but wireless is not active. The wireless button is activated as the Bluetooth icon is available in the system tray. Iíve tried all steps with the button activated and deactivated (Bluetooth icon not in system tray).

With the kernel driver not working I downloaded and extracted the windows driver. Then I went to System > Administration > Add/Remove software and installed ndiswrapper-tools and ndisgtk. I ran ndisgtk and installed the wireless drivers by selecting netwbw02.INF and netwsw02.INF from the extracted Windows 7 64 bit drivers. Ndisgtk says Hardware present:Yes for both drivers. I ran modprobe iwlwifi and modprobe ndiswrapper and rebooted and nothing has changed. So Iíve signed up for Linuxquestions.org to look for community help.

I was going to swap out the wireless card but the one in this newer laptop uses an m.2 connector like the m.2 SSDs while all the older wireless cards in the other laptops we have use standard laptop PCI connectors.

I was able to find the Intel Wireless device id's page and your AC 8260 is listed:

https://wikidevi.com/wiki/Intel#Wireless-AC

Somewhere there might be a page listing all the gory details on the Intel AC 8260
including 'Probable Linux Driver' as in this out of tree Netgear WNDA3100v3 dual band
N600 I just got:

https://wikidevi.com/wiki/Netgear_WNDA3100v3

I always have to spend time hunting around for device drivers for these devices that
come with only a Windows driver CD.

Thanks. I perused that site, which basically leaves me where I was before. Knowing the wireless adapter is supported by the kernel driver, but support for the model we have isn't included in the kernel (2.3x) in RHEL 6.5. Or the RHEL 7 from what I can tell.

this is redhat so....

call your paid for support

also rhel was never designed to run on laptops
it is after all mostly for servers and desktops in the office

some laptops will run it mostly well most of the time , but not all laptops
and the 6 series is starting to show it's age . I would not expect a even older rhel6.5 to run well on new laptop hardware

for that , use fedora or opensuse

Would be nice but this is what we have. It's a government laptop. Contact is for this laptop and this version of this distro. Might take weeks to hear back from the point of contact since they care more about Macs and PCs than Linux so I don't have the contact info for the support from redhat. So first stop was laptop vendor support, then Intel. Redhat is next but the contact isn't in my name so I don't have any way to access their paid support. So I am stuck where I am for now. Just hoping someone else in the community has experienced this set of variables and knows how to fix it. If I can get it working I'll post the solution.

then use a redhat approved laptop with redhat approved hardware
redhat has a compatibility list on their web site

also you will need the paid for redhat support to install the SECURITY back ports to have it LOCKED as 6.5 and not the current 6.8

you will need there help in getting this wireless card working

also you will need the paid for redhat support to install the SECURITY back ports to have it LOCKED as 6.5 and not the current 6.8 < The script that we run to overlay it activates the subscription so it gets updates, but none of the OS's receive major updates without our intervention. Not Windows, not Redhat, not iOS, not Android, not MacOS, etc.

Unfortunately I have to work at the speed of government so someone else will probably see this thread and answer me before I get THEIR help.

I know where you're coming from. If it was me, once I found out about the IWLWIFI driver not having the 8260 support in the "old" kernel I would have switched to another distro. Actually I was going to try a different kernel first, but of course that was shot down. So, hoping against hope that someone found a good workaround and sees this thread. Either that or the end user's boss gets involved and decides they no longer want to wait. Then my boss might intervene and send back the state of the art laptop and send them an older, slower one that works. Until then all I can do is wait for that magical answer from here or from the Linux POC or from someone with the login to ask redhat for help.

I have taken your advice though and sent an email to the general redhat support team to see if they can tell me if there is someone else who administers our Redhat account that I could try to reach out to.
