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/245649229","html_url":"https://github.com/raspberrypi/linux/issues/1342#issuecomment-245649229","issue_url":"https://api.github.com/repos/raspberrypi/linux/issues/1342","id":245649229,"user":{"login":"thomasf","id":330847,"avatar_url":"https://avatars.githubusercontent.com/u/330847?v=3","gravatar_id":"","url":"https://api.github.com/users/thomasf","html_url":"https://github.com/thomasf","followers_url":"https://api.github.com/users/thomasf/followers","following_url":"https://api.github.com/users/thomasf/following{/other_user}","gists_url":"https://api.github.com/users/thomasf/gists{/gist_id}","starred_url":"https://api.github.com/users/thomasf/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/thomasf/subscriptions","organizations_url":"https://api.github.com/users/thomasf/orgs","repos_url":"https://api.github.com/users/thomasf/repos","events_url":"https://api.github.com/users/thomasf/events{/privacy}","received_events_url":"https://api.github.com/users/thomasf/received_events","type":"User","site_admin":false},"created_at":"2016-09-08T16:07:30Z","updated_at":"2016-09-08T16:07:30Z","body":"I've also tested external bt dongle + internal wifi but the internal wifi sometimes hangs even when the internal bcm bt driver isn't loaded.
