I managed to get the wifi running (again), after very many annyoing month with Ubuntu. So far I haven't experienced any any freezes. And this is what I did:
1. Download the latest wifi driver from Marvel: http://git.marvell.com/?p=mwifiex-firmware.git;a=blob;f=mrvl/usb8797_uapsta.bin;h=0ce6c4ec307880d34bbef3b6ccd359617914f156;hb=e92f8b3f65443764297b947b1843955d9a65dde7 2. Backup and replace the outdated firmware file with the driver you just downloaded: sudo mv /lib/firmware/mrvl/usb8797_uapsta.bin /lib/firmware/mrvl/usb8797_uapsta.bin.bak sudo cp ./mrvl_usb8797_uapsta.bin /lib/firmware/mrvl/usb8797_uapsta.bin 3. Update Ubuntu's kernel to the latest stable mainline version: https://wiki.ubuntu.com/Kernel/MainlineBuilds#Installing_upstream_kernels_.28manually.29 http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4-wily/ 4. Restart your system and boot the latest kernel. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1319366 Title: 1286:2044 [Microsoft Surface Pro 2] Marvell 88W8797 not working in 14.04 kernel 3.13.0-24-generic Status in linux package in Ubuntu: Triaged Bug description: Marvell WiFi on Surface Pro 2 does not work in a fresh install of 14.04 with 3.13.0-24 kernel.
