Intel Centrino Advanced-N 6235 [8086:088e] Subsystem [8086:4060] WiFi doesnt connect when I come back from sleep mode

[Vinayak Aggarwal]

It tries to connect when I come back from sleep mode but isn't able to connect. I always need to restart laptop to start using it again.

Also while using google chrome on pressing chrome button the alignment of screens in mini view is towards left and has too much extra space on write and it doesn't gets resize according to the view of the screen instead gets stretched making it unable to identify.

Try to reinitialize wifi driver: "sudo modprobe -r iwlwifi ; sudo modprobe iwlwifi" after sleep and resume.

[You-Sheng Yang (vicamo)]

Please re-upload syslog with symptoms reproduced once so that people may investigate what happened. That is to:

1. reboot
2. make sure you connect to wireless network automatically
3. suspend the system for some time
4. wake the system and check if wifi reconnect
5. if not, then attach the output of `journalctl > syslog.txt`; if yes, repeat 3. - 5.
