[Bug 1414010] Re: wifi problem

 

I've been having this issue since I've bought my laptop.  No issue at all using windows.  Connection drops every now and then on linux (ubuntu) and android (4.4r2 using 3.18 kernel as well).  Also can now always reproduce when rebooting from android-x86 to ubuntu where the connection simply won't activate at all with tons of syslog errors!  I first tought it was mainly due to sleep/resume but it's totally unreleated.  I now presume the interface need a some sort of full reset at reboot or is badly re-initialized after reboot.  Even then at cold boot the connection eventually drops as well.

	Product Name: HP Split 13 x2 PC (HP Split 13-m110ca x2 PC)

Two issues:
1- badly re-initialized after reboot resulting with not being able to activate wifi connection resulting in a need for full shutdown + cold-boot (rebooting from android-x86 to ubuntu does that)
2- connection drops often even after cold-boot

Issue still on-going with 3.19
