FYI I had trouble with my network devices with kernel 4.0, but reverting to 3.16 did the trick. Also see, if the correct kernel module for your card is used. However, I think, it is. And, of course, check, if youre card needs firmware. If so, install the required firmware. Last but not least, you can check with some linux livefile systems, like Knoppix, or Debian Livefile. Hope this helps. Good luck! Hans -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

This notebook has onboard wifi, no physical switch, but a combination of keys FN+F2 that would supposedly turn it on or off. This combination never worked since day one of all older debians I started with, and I never used it. But since you mentioned, I tried some keystrokes, no luck though. Let me put lspci here. Maybe I'm mistaken. lspci shows: # lspci 00:00.0 Host bridge: Intel Corporation 2nd Generation Core Processor Family DRAM Controller (rev 09) 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 00:16.0 Communication controller: Intel Corporation 6 Series/C200 Series Chipset Family MEI Controller #1 (rev 04) 00:1a.0 USB controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #2 (rev 05) 00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 05) 00:1c.0 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 1 (rev b5) 00:1c.1 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 2 (rev b5) 00:1c.3 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 4 (rev b5) 00:1c.4 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 5 (rev b5) 00:1c.7 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 8 (rev b5) 00:1d.0 USB controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #1 (rev 05) 00:1f.0 ISA bridge: Intel Corporation HM67 Express Chipset Family LPC Controller (rev 05) 00:1f.2 SATA controller: Intel Corporation 6 Series/C200 Series Chipset Family 6 port SATA AHCI Controller (rev 05) 00:1f.3 SMBus: Intel Corporation 6 Series/C200 Series Chipset Family SMBus Controller (rev 05) 05:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

No windows near me in any machine. :) Sure seems like a hardware failure. I'm starting to think that also. But today this notebook is so weird, I don't know. I'm still puzzled. Maybe something debian-related, you know. These Debian Jessie 8.0 and 8.1 are a bit unstable to my taste. I hope we move on soon to 8.2.(*) oh- one other thing to try. boot up into BIOS and see if there's anything at all in there about your WLAN hardware.
