Since then the wlan freezes after while (several hours) of usage couldn't find out if it's due to havy wifi usage or not, because I haven't change the software I guess it has to do with the new hardware. When the wlan freezes the pi can't be reached any longer, neither ifdown + ifup nor restart networking service helps in this case, I have to reboot the system to get it back to work, syslog doesn't say much only this:\r\ndhcpcd[522]: wlan0: fe80::8af7:c7ff:fece:5912: expired option 25, \r\n\r\nI've tried to change these settings so far, but without improvement:\r\n\r\nsudo nano /etc/network/interfaces\r\nwireless-power off\r\n\r\nsudo nano /etc/sysctl.conf\r\nat the end of the file add the following line\r\nvm.min_free_kbytes = 16384\r\n\r\nsudo nano /boot/cmdline.txt\r\nAt the end of the line, add: \r\nsmsc95xx.turbo_mode=N\r\ndwc_otg.dma_enable=1 dwc_otg.dma_burst_size=256"},"comment":{"url":"https://api.github.com/repos/raspberrypi/linux/issues/comments/245648363","html_url":"https://github.com/raspberrypi/linux/issues/1342#issuecomment-245648363","issue_url":"https://api.github.com/repos/raspberrypi/linux/issues/1342","id":245648363,"user":{"login":"pelwell","id":8911409,"avatar_url":"https://avatars.githubusercontent.com/u/8911409?v=3","gravatar_id":"","url":"https://api.github.com/users/pelwell","html_url":"https://github.com/pelwell","followers_url":"https://api.github.com/users/pelwell/followers","following_url":"https://api.github.com/users/pelwell/following{/other_user}","gists_url":"https://api.github.com/users/pelwell/gists{/gist_id}","starred_url":"https://api.github.com/users/pelwell/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/pelwell/subscriptions","organizations_url":"https://api.github.com/users/pelwell/orgs","repos_url":"https://api.github.com/users/pelwell/repos","events_url":"https://api.github.com/users/pelwell/events{/privacy}","received_events_url":"https://api.github.com/users/pelwell/received_events","type":"User","site_admin":false},"created_at":"2016-09-08T16:04:44Z","updated_at":"2016-09-08T16:04:44Z","body":"Define stable.\r\n\r\nThe hash I (finally) gave you will is for the 20th June firmware release, which you will get if you run:\r\n```\r\nsudo apt-get update raspberrypi-kernel\r\nsudo apt-get update raspberrypi-bootloader\r\n```\r\nI'm not aware of a single place that contains the hash of the most recent \"stable\" release, but by going through RPI-Distro as I did then cross-referencing with the Hexxeh repo you can get rpi-update hashes for any release you like. If you consider the 2016-05-23 release to be stable because it was part of the last full Raspbian release then you want hash 3b98f7433649e13cf08f54f509d11491c99c4c0b which translates to an rpi-update hash of 2b9c0bfacfc11ee8bb9b30dc9cdb36289698f8a8 ."}}
