Basically I have spent the last 6 hours trying to get the wifi to work on my Surface Pro 2 after I just installed the 64bit Ubuntu 14.04 LTS. The Ubuntu install worked fine and is now the only OS on my surface pro 2, I did not dual boot.

I have read every forum and website I could find and tried numerous fixes and nothing has worked. I'm pretty sure I need to install new Wifi drivers however I can't seem to find any information on what drivers I need to download and how to then install them.

I have found that the surface pro 2 uses the Marvell 350N chipset and a lot of things I have read said that this should help me to determine what drivers I need but I am completely lost at this point. I should also point out that I am a complete noob at this type of stuff. I have also seen a lot of people asking for details about the wireless card so here are my results after typing lspci in terminal.

tom@tom-Surface-Pro-2:~$ lspci
00:00.0 Host bridge: Intel Corporation Haswell-ULT DRAM Controller (rev 0b)
00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 0b)
00:03.0 Audio device: Intel Corporation Haswell-ULT HD Audio Controller (rev 0b)
00:14.0 USB controller: Intel Corporation Lynx Point-LP USB xHCI HC (rev 04)
00:16.0 Communication controller: Intel Corporation Lynx Point-LP HECI #0 (rev 04)
00:1b.0 Audio device: Intel Corporation Lynx Point-LP HD Audio Controller (rev 04)
00:1d.0 USB controller: Intel Corporation Lynx Point-LP USB EHCI #1 (rev 04)
00:1f.0 ISA bridge: Intel Corporation Lynx Point-LP LPC Controller (rev 04)
00:1f.2 SATA controller: Intel Corporation Lynx Point-LP SATA Controller 1 [AHCI mode] (rev 04)
00:1f.3 SMBus: Intel Corporation Lynx Point-LP SMBus Controller (rev 04)

Any help would be greatly appreciated!

I believe your device Bus 001 Device 007: ID 1286:2044 Marvell Semiconductor, Inc. is driven by the driver mwifiex_usb. I am not sure that the driver version included in Ubuntu 14.04 yet covers it. Please load it and check the log for messages.

sudo modprobe mwifiex_usb
dmesg | grep mwi

Is it missing firmware? If so, please download this file to your desktop: http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.149.3_all.deb Now, back to the terminal:

cd ~/Desktop
sudo dpkg -i linux*.deb

Reboot and your wireless should be working.
