After a while, the wireless interface randomly drops and only a reboot will bring back the wireless interface. This issue was pretty bad using the default installation provided by Dell (12.04). I then upgrade to 12.10 to see the same sort of issue, currently I am running Ubuntu 13.04 running KDE and kernel 3.10 root@fl1ght:~# uname -a && lshw -class network Linux fl1ght 3.10.0-999-generic #201305240428 SMP Fri May 24 08:28:59 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux *-network description: Wireless interface product: Centrino Advanced-N 6235 vendor: Intel Corporation physical id: 0 bus info: pci@0000:01:00.0 logical name: wlan0 version: 24 serial: ************ width: 64 bits clock: 33MHz capabilities: pm msi pciexpress cap_list ethernet physical wireless configuration: broadcast=yes driver=iwlwifi driverversion=3.10.0-999-generic firmware=18.168.6.1 latency=0 link=no multicast=yes wireless=IEEE 802.11abgn resources: irq:44 memory:*********** *-network description: Ethernet interface physical id: 2 logical name: eth0 serial: *************** size: 1Gbit/s capacity: 1Gbit/s capabilities: ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd 1000bt 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=asix driverversion=22-Dec-2011 duplex=full firmware=ASIX AX88178 USB 2.0 Ethernet ip=10.0.5.100 link=yes multicast=yes port=MII speed=1Gbit/s root@fl1ght:/var/log# lsmod |grep iwl iwldvm 249110 0 mac80211 615800 1 iwldvm iwlwifi 181947 1 iwldvm cfg80211 495341 3 iwlwifi,mac80211,iwldvm I currently have a usb Gigabit Ethernet Adaptor attached, hence why the the Ethernet interface (the laptop is an ultrabook with no ethernet ports as standard) I have downloaded the latest intel firmware from http://wireless.kernel.org/en/users/Drivers/iwlwifi hoping it could be firmware related or atleast different than whats provided with Ubuntu and unfortunately no difference: root@fl1ght:/var/log# ls -al /lib/firmware/|grep iwl -rw-r--r-- 1 root root 335056 May 25 02:30 iwlwifi-1000-3.ucode -rw-r--r-- 1 root root 337520 May 25 02:30 iwlwifi-1000-5.ucode -rw-r--r-- 1 root root 337572 May 25 02:30 iwlwifi-100-5.ucode -rw-r--r-- 1 root root 689680 May 25 02:30 iwlwifi-105-6.ucode -rw-r--r-- 1 root root 701228 May 25 02:30 iwlwifi-135-6.ucode -rw-r--r-- 1 root root 695876 May 25 02:30 iwlwifi-2000-6.ucode -rw-r--r-- 1 root root 707392 May 25 02:30 iwlwifi-2030-6.ucode -rw-r--r-- 1 root root 150100 May 25 02:30 iwlwifi-3945-2.ucode -rw-r--r-- 1 root root 187972 May 25 02:30 iwlwifi-4965-2.ucode -rw-r--r-- 1 root root 345008 May 25 02:30 iwlwifi-5000-1.ucode -rw-r--r-- 1 root root 353240 May 25 02:30 iwlwifi-5000-2.ucode -rw-r--r-- 1 root root 340696 May 25 02:30 iwlwifi-5000-5.ucode -rw-r--r-- 1 root root 337400 May 25 02:30 iwlwifi-5150-2.ucode -rw-r--r-- 1 root root 454608 May 25 02:30 iwlwifi-6000-4.ucode -rw-r--r-- 1 root root 444128 May 25 02:30 iwlwifi-6000g2a-5.ucode -rw-r--r-- 1 root root 677296 May 25 02:30 iwlwifi-6000g2a-6.ucode -rw-r--r-- 1 root root 460236 May 25 02:30 iwlwifi-6000g2b-5.ucode -rw-r--r-- 1 root root 679436 May 25 02:30 iwlwifi-6000g2b-6.ucode -rw-r--r-- 1 root root 463692 May 25 02:30 iwlwifi-6050-4.ucode -rw-r--r-- 1 root root 469780 May 25 02:30 iwlwifi-6050-5.ucode I have tried enabling the following module parameters: root@fl1ght:~# cat /etc/modprobe.d/iwlwifi.conf |grep option #options iwlwifi 11n_disable=1 swcrypto=2 power_save=0 I had the exact same issue.

At the end you will notice Failed to load firmware chunk. I do an rmmod iwldvm and iwlwifi and the modules are successfully removed and I can then reinsert both modules but the wireless interface completely disappears and dmesg says that it could not load the firmware. root@fl1ght:/var/log# dmesg |grep -i firmware [ 0.143458] [Firmware Bug]: ACPI: BIOS _OSI(Linux) query ignored [ 44.270456] iwlwifi 0000:01:00.0: loaded firmware version 18.168.6.1 op_mode iwldvm [26486.356816] iwlwifi 0000:01:00.0: Failed to load firmware chunk! Ive also noticed the onboard touchpad acts extremely weird and I end up being forced to do a reboot (if I have external / mice keyboard and usb ethernet adaptor everything is fine it runs normally -- when the laptop has nothing plugged in and the wireless dies the laptop begins to stall and needs to be rebooted - not sure why this other than the kernel module crashing. ) The wireless usually works fine for at least a few hours, before this happens. I can suspend and resume just fine everything works, but left on and using wireless for a few hours it suddenly does this, in fact the time it takes is completely random as well. I am not sure at this point if it is a faulty wireless card or driver / firmware related. The dell laptop itself has had the latest firmware installed (A08) downloaded and installed from the dell support site. Any help you could provide I would greatly appreciate, I can provide you with any further information you require. Thank you in advance, Kind Regards, Vamegh Hedayati
