Looks like one of those firmware-related bugs. Have you checked firmware-related packages like firmware-realtek or firmware-non-free ?

Package: linux-image-4.7.0-1-amd64Hi there,I'm using Debian 8.5 sid & XFCE and so far everything was fine.Two days ago after an apt-get update/upgrade i got a prompt to upgrade about 220 files , an operation that would free around 500MB of HDD, including linux-image/headers of 4.7.0.1 - Debian version 4.7.6.1 as an upgrade to previous installed (and nicely working) 4.7.5.1PS: I read on Debian Wiki that rtlwifi/rtl8723be driver is a driver provided by Linux Kernel, and this is why i tagged this bug as a linux-image bug. Please let me know if i have to assign a different package.After completing this 220 files upgrade and rebooted, my wifi card stopped working entirely (rtlwifi/rtl8723be).While the wifi network indicator was looking alive, I had no internet access and also i had not even lan access.Moreover wifi icon starts showing disconected and reconnected a lot of times.Once every 30 minutes i had some limited internet connection and then lost again.Since Debian keeps the stable linux-image 3.16 , i was capable to boot with stable kernel and wifi worked correctly.Using modprobe -r rtl8723be and again modprobe rtl8723be has no improvement.The strange thing is that i downgraded linux-image and linux-headers back to the old good working version 4.7.0.1 / 4.7.5.1 using the /testing repository, but still wifi refuses to work.As a desperate step i further downgraded some more packages , but still wifi refuses to work.This is the list of all downgraded packages:gir1.2-networkmanager-1.0network-managerwpasupplicantlinux-compiler-gcc-5-x86linux-headers-4.7.0-1-amd64:amd64 linux-headers-4.7.0-1-common:amd64 ( linux-image-4.7.0-1-amd64:amd64 linux-kbuild-4.7:amd64linux-libc-dev:amd64Could somebody help and advise what is going wrong....?I attached the following files:* apt history log file (includes list of 220 apt-get upgraded packages)* apt list --installed log file (all the files installed in my system)* File rtl3-16.log with modinfo rtl8723be and rtlwifi under 3.16 kernel* File rtl3-16.log with modinfo rtl8723be and rtlwifi under 3.16 kernel* lsmod, lspci, lsusb files either for 3.16 kernel boot and for 4.7 kernel boot.RegardsGeorge Vasiliou
