David Carter - that's no good! My guess would be that you now have a missing firmware problem.
Run the following command in a terminal: "ls /lib/firmware/iwlwifi-7*" you should have at least one file listed. I actually have two: /lib/firmware/iwlwifi-7260-7.ucode /lib/firmware/iwlwifi-7260-8.ucode If you don't then you definitely have missing firmware . If you do have a file, you might not have the correct one for your edition of the wireless card. Note that I upgraded to Ubuntu 14.04 (rather than clean install), and I had put the -7.ucode version of the firmware file in place months back in order to get the card to work at all (the older kernels didn't support this card at all). Here's a summary of how I installed backports for this card and the firmware: Download the ucode file for the 3.13 kernel here: http://wireless.kernel.org/en/users/Drivers/iwlwifi?action=AttachFile&do=get&target=iwlwifi-7260-ucode-22.0.6.0.tgz#Firmware Download backports for 3.13 here: http://drvbp1.linux-foundation.org/~mcgrof/rel-html/backports/ Un-tar the downloaded files: tar xvf backports-3.13.2-1.tar.xz tar xvf iwlwifi-7260* Then build backports for iwlwifi cd backports-3.13.2-1/ make defconfig-iwlwifi make sudo make install Then copy the firmware ucode file to /lib/firmware cd .. cd iwlwifi* sudo cp iwlwifi* /lib/firmware -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1305305 Title: 8086:08b1 [Sony VAIO SVP1321M2E] Wifi keeps dropping.
