Roompam Skukla, the next step is to fully commit bisect from kernel 4.2 to 4.4 in order to identify the last good kernel commit, followed immediately by the first bad one. This will allow for a more expedited analysis of the root cause of your issue. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ?
Please note, finding adjacent kernel versions is not fully commit bisecting. Also, the kernel release names are irrelevant for the purposes of bisecting. It is most helpful that after the fix commit (not kernel version) has been identified, you then mark this report Status Confirmed. Thank you for your help. -- 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/1619646 Title: Wi-Fi signal strength very low beside router, gets lower on moving 2-3 metres away from router Status in linux package in Ubuntu: Incomplete Bug description: Laptop gets enough Wi-Fi signals beside router but as you move 2-3 metres away from router it barely gets one line strength. And then won't connect due to low strength. Wi-Fi worked fine before the 3-4 kernel updates but after the updates I'm facing this problem.
