<html><body><div style="font-family: Arial; font-size: 12pt; color: #000000"><div>Hi Levi, welcome to the CLUE list!!<br></div><div><br></div><div> First off, I've got to give you credit for 1) making a real, honest effort to resolve this yourself, and 2) providing a lot of good data for us to "chew on". With that said...<br></div><div><br></div><div> If I'm interpreting the output correctly, it appears that the 'iwlwifi' module is loading correctly, & the hardware is being detected/recognized. This isn't intended to be condescending at all, but does the device appear in the output of 'ifconfig -a'?? I'm wondering if perhaps the interface is there, but simply needs to be enabled using "ifconfig wlan0 UP" (or similar). Speaking from my own experience, it's pretty easy sometimes to overlook the "simple stuff" & dive right into the deeper waters, so to speak.<br></div><div><br></div><div> Two other thoughts - are there any relevant entries in the system log <em>(/var/log/messages on the RHEL variants that I'm familiar with, not 100% sure if it's the same on the Debian side of the fence)</em>. Finally, it occurs to me that it *might* be worthwhile to download & fire up a LiveCD (or LiveUSB) version of a Red Hat/Fedora/CentOS distro, temporarily boot to that, & see if the wireless interface is recognized/activated, or if you can get some other data on it that way. Sometimes it's helpful to be able to look at the problem from a slightly different angle...<br></div><div><br></div><div> Finally, did the wireless interface work under WinDoze?? If so, that would likely rule out faulty hardware.<br></div><div><br></div><div>Again, welcome to the list!<br></div><div><br></div><div>T.<br></div><div><br></div><hr id="zwchr"><div style="color:#000;font-weight:normal;font-style:normal;text-decoration:none;font-family:Helvetica,Arial,sans-serif;font-size:12pt;"><b>From: </b>"Levi S. Darrell" <levidarrell@gmail.com><br><b>To: </b>clue@cluedenver.org<br><b>Sent: </b>Thursday, February 25, 2016 3:48:13 PM<br><b>Subject: </b>[clue] Wireless card not working<br><div><br></div>Dear all at CLUE,<br><div><br></div> Thanks for your attention to my email. I have tried posting my problem on the debian mailing lists, as well as on the mailing list at linuxfromscratch.org, but have had no responses. I am hoping someone at CLUE can help me <br>with my problem. I live in Eastern Colorado and I have been using linux on my computers for a couple years now.<br><div><br></div> In January of 2016, I purchased a Lenovo IdeaPad Y700 laptop, which had Windows 10 pre-installed on it. Since that time I have been unable to get my Intel Wireless 8260 Wireless card to work, either with my Debian Jessie <br>stable distro, or with an LFS system that I tried to build from scratch on another disk partition. After several hours searching the internet for solutions, I have seen that this is a common problem with Lenovo computers. Here <br>are the solutions that I have tried:<br> <br> 1. I recompiled the kernel, using the stable 4.4.1 version that I obtained from www.kernel.org via wget. Using apt, I downloaded the package kernel-package. Using menuconfig, I selected the iwlwifi drivers in the wireless <br>options. I made the image using the make-kpkg command, and compiled it using the fakeroot make-kpkg --initrd --revision=1.0.custom kernel_image command. I rebooted, but the drivers seemed not to have been correct, and the wifi card <br>continued not to work.<br><div><br></div> 2. I then downloaded the most recent backports package using wget https://www.kernel.org/pub/linux/kernel/projects/backports/2016/01/22/backports-20160122.tar.gz. I untarred the package, issued the commands make <br>defconfig-wifi && make && make install. The program seemed to compile without any errors. I then searched in the /lib/modules/4.4.1/build/drivers/net/wireless/iwlwifi/pcie/drv.c file, where on line 425 I read:<br><div><br></div> {IWL_PCI_DEVICE(0x24F3, 0x1010, iwl8260_2ac_cfg)},<br> <br>This seemed to indicate to me that my device should be supported, based on the lspci -nnk | grep 0280 -A2 command, which gives the following output:<br><div><br></div> 08:00.0 Network controller [0280]: Intel Corporation Wireless 8260 [8086:24f3] (rev 3a)<br> Subsystem: Intel Corporation Device [8086:1010]<br> Kernel driver in use: iwlwifi<br> <br>However, upon rebooting my machine, my wifi card still did not work.<br><div><br></div> 3. I then attempted to manage a problem with rfkill by searching in the file /lib/modules/4.4.1/build/drivers/platform/x86/ideapad-laptop.c, which states:<br> <br> /*<br> * Some ideapads don't have a hardware rfkill switch, reading VPCCMD_R_RF<br> * always results in 0 on these models, causing ideapad_laptop to wrongly<br> * report all radios as hardware-blocked.<br> */<br><div><br></div>At line 902, I added the following:<br><div><br></div> {<br> .ident = "Lenovo Yoga 700",<br> .matches = {<br> DMI_MATCH(DMI_SYS_VENDOR, "LENOVO"),<br> DMI_MATCH(DMI_PRODUCT_VERSION, "Lenovo ideapad Y700 Touch-15ISK"),<br> },<br> },<br><div><br></div>This was because the output of the command dmidecode | grep -A3 '^System Information' was:<br><div><br></div> System Information<br> Manufacturer: LENOVO<br> Product Name: 80NW<br> Version: Lenovo ideapad Y700 Touch-15ISK<br><div><br></div>I guessed based on this that DMI_PRODUCT_VERSION should therefore be set to "Lenovo ideapad Y700 Touch-15ISK". However, upon reboot, rfkill list still showed the following:<br><div><br></div> 0: hci0: Bluetooth<br> Soft blocked: yes<br> Hard blocked: no<br> 1: ideapad_wlan: Wireless LAN<br> Soft blocked: no<br> Hard blocked: yes<br> 2: ideapad_bluetooth: Bluetooth<br> Soft blocked: no<br> Hard blocked: yes<br> 3: phy0: Wireless LAN<br> Soft blocked: no<br> Hard blocked: no<br> <br> I don't know why phy0 is showing up as a logical device, because that had not been showing up prior to my updating the kernel to 4.4.1. However, I don't think this is part of the problem. Since I am not a developer and I am not really versed in C or any other language, I have no idea if I made some kind of a mistake in some of the fixes that I tried to apply. I believe I have exhausted my capacity to troubleshoot the problem using web searches, and I <br>therefore am seeking some help here.
