I've got an M17X-R5 with the Intel 4800 cpu, Nvidia 3d graphics and it came with 5g wifi and a killer ethernet card. This is to replace my ageing M17x R1 which until recently worked perfectly with all I threw at it from Ubnutu 10.04 onwards.   When I come to install Ubuntu 13.04 on the new Alienware, all appears well except it doesn't detect an internet connection to download the updates whist it installs.  I've tried with a physical cable, via wifi and can only get it to detect a wireless connection if I plug in an old USB wifi adapter.  After installing with the USB wifi plugged in, and all patches applied, it still refuses point blank to detect a network unless I use the USB adapter.  I've tried installing Jockey and looking for additional drivers/hardware but none are found.    I'm very comfortable with Unix/Linux/AIX etc, but have to admit that when it comes to drivers and Linux, I'm a novice.  Any help would be appreciated.  EDIT: In answer to PJ Singh's very pertinent question in the comment section, this is a snip from the lspci command taken at boot from a USB boot disk (Try Ubuntu option) without any external wifi dongles installed:  08:00.0 Ethernet Controller: Qualcomm Atheros Killer E2200 Gigiabit Ethernet Controller (rev 10) 0a:00.0 Network Controller: Broadcom Corporation Device 43b1 (rev 03)   I should also note that when I said to begin with that it couldn't find any wifi networks  to install the updates over, it actually couldn't find any wireless adapters.  Edit:  Added output from process here (nicer formatting)  root@m17xr5-lnx:/usr/src/b43b1-6.30.223.95# lsmod | grep wl wl                   4117081  0  lib80211               14352  2 wl,lib80211_crypt_tkip cfg80211              510937  3 wl,mac80211,rt2x00lib root@m17xr5-lnx:/usr/src/b43b1-6.30.223.95# cat /etc/modules  wl root@m17xr5-lnx:/usr/src/b43b1-6.30.223.95#    Edit:  Resolved this today (September 29th 2013) by installing the latest Broadcomm drivers that are available with 13.10.  No compilation required, just installed using the package manager and loh-and-behold, the wireless adapter came to life - didn't even need a reboot.

I bought a new computer, hoping to dual boot Win 8 and Ubuntu 13.04.  I have successfully installed both OS, but in Ubuntu I have no connection to the internet, even though the ethernet cable is plugged in and internet works perfectly in Win 8. Already in the Ubuntu installer, it says that I have no internet connection.  Things that might be of interest:   I have this motherboard: MSI Z87-G45 Gaming () Internet did not work in Win 8 until I installed the networking drivers that came with the motherboard (Killer Ethernet something) I have tried different installation configurations, tried v. 13.04, 12.04 and 12.10, and tried installing on a separate hard drive. (the fact that the installer says "no internet connection" seems to indicate that the problem has nothing to do with the installation though.) I can't even reach my router at 192.168.0.1.  The motherboard has no wireless capabilities.  If I run the terminal command lspci I get the following output (among other things):       03:00.0 Ethernet controller: Qualcomm Atheros Killer E2200 Gigabit Ethernet Controller (rev 13)   I have spent hours and hours googling, trying many different suggested methods and not quite finding someone who seems to be having the same problem.

I upgraded Ubuntu from 11.10 to 12.04, until which wireless was working just fine. After the upgrade and reboot, wireless is not even being detected (When I click the network manager icon in the top panel, it does not show the wireless networks. Neither the Enable wireless option is there). But my laptop's LED indicator shows wireless is on.  This is a Dell Vostro 3450 laptop with:     Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01)** (from lspci). Is any other info needed?   How do I get Wifi working?

I have installed Ubuntu 15.04 on my new Intel NUC   However the wifi does not work.  It complains (in dmesg) that the iwlwifi module was unable to load the firmware code because iwlwifi-3165-10.ucode could not be found.  I've tried installing newer versions of iwlwifi (from backports), but that seemed very complicated and didn't seem to help.

The wifi on my asus x550ca laptop is not working. Ethernet works fine in ubuntu but wifi does not work. Wifi works just fine when I boot up windows 8.1 though. Is there any special driver I have to install?

I've just decided to jump into the world of Ubuntu, so far I encountered no problems until I tried to connect to my wireless network. I'm running Ubuntu on my laptop, Acer Aspire 5333-2880, which has an Acer Nplify 802.11b/g/n wireless card.  After browsing for an answer, I think the problem is a missing driver. input:   lspci | grep Network   output:     02:00.0 Network controller; Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01)   I found a couple of answers that might be right, but I have problems with both of them.    It requires me to load the site in my laptop, but I can't do it without internet and I have no idea how to save this into a USB.  But I have no idea how to really run or use this, and I wouldn't like to screw it up.    Any advice or other possible solutions will be greatly appreciated!   EDIT.  Thanks a lot for your input Marko and Jorge. I am sure the problem was with one of the drivers, but I was too distracted, or tired yesterday to realize I didn't restart my computer after installing. As soon as I got turned on my computer again, it was working. Annoyingly, I am not sure what the problem was exactly nor what exactly fixed it.  But still, thanks a lot Marko for the intel on how to build packages, I am sure it will be very useful later on!

To start off I am very new to Ubuntu so when explaining do not use shortcuts please because I will not understand. So I installed Ubuntu 15.10 on my Hp Envy and the wireless card is not working. I have been hassling with it all day and I'm finally giving in to making a forum post. The Card is a Intel 7265 Wireless AC(revision61). I am currently attempting to install a newer firmware for it that I downloaded from intels website but I can not for the life of me figure out how to get the file into the firmware folder. So basically I'm making a plea to help me get the firmware installed and if that doesn't work provide more insight before I say goodbye to Ubuntu. Thanks in advance!  lspci -knn | grep Net -A2 02:00.0 Network controller [0280]: Intel Corporation Wireless 7265 [8086:095a] (rev 61)     Subsystem: Intel Corporation Dual Band Wireless-AC 7265 [8086:5010]     Kernel driver in use: iwlwifi  Rfkill List 0: acer-wireless: Wireless LAN     Soft blocked: yes     Hard blocked: no 1: hci0: Bluetooth     Soft blocked: yes     Hard blocked: no 2: phy0: Wireless LAN     Soft blocked: no     Hard blocked: no  dmesg | grep iwlwifi  [    2.089673] iwlwifi 0000:02:00.0: Unsupported splx structure [    2.092497] iwlwifi 0000:02:00.0: Direct firmware load for iwlwifi-7265D-15.ucode failed with error -2 [    2.093049] iwlwifi 0000:02:00.0: Direct firmware load for iwlwifi-7265D-14.ucode failed with error -2 [    2.113852] iwlwifi 0000:02:00.0: loaded firmware version 25.30.13.0 op_mode iwlmvm [    2.148273] iwlwifi 0000:02:00.0: Detected Intel(R) Dual Band Wireless AC 7265, REV=0x210 [    2.149810] iwlwifi 0000:02:00.0: L1 Enabled - LTR Enabled [    2.150242] iwlwifi 0000:02:00.0: L1 Enabled - LTR Enabled [    2.240713] iwlwifi 0000:02:00.0 wlp2s0: renamed from wlan0 [   14.008741] iwlwifi 0000:02:00.0: L1 Enabled - LTR Enabled [   14.009388] iwlwifi 0000:02:00.0: L1 Enabled - LTR Enabled [   14.070823] iwlwifi 0000:02:00.0: L1 Enabled - LTR Enabled [   14.071356] iwlwifi 0000:02:00.0: L1 Enabled - LTR Enabled   After sudo modprobe -r acer_wmi  rfkill list 1: hci0: Bluetooth     Soft blocked: no     Hard blocked: no 2: phy0: Wireless LAN     Soft blocked: no     Hard blocked: no
