My PC's Wifi stopped working recently, probably after a kernel upgrade or so. The Wifi connects to the SSID & the port is assigned an IP address. However I am not able to Ping anything apart from the host itself. Tried rebooting, re-connecting, Wifi Router reboot, Disabled GUFW, etc but nothing worked. Everything else is working fine in the LAN.

Tried to add below Grub boot parameter, but it dint helped:

pcie_aspm=off

Changed the below parameter to disable power saving mode, dint helped even - /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf:

wifi.powersave = 3 ==> 2

Changed the Power saving mode in Power management to Balanced, issue still existed.

Wifi Dongle is TP-Link Archer T3U [Realtek RTL8812BU]

I suspect either a bug in kernel or firmware or else hardware issues. Please guide me to figure out the issue and help resolve if possible.

Below is the output of DMESG command and Wireless-info script:

My expansion Hard disk is having error and some data is lost/corrupted. I was using GParted to expand a partition. I got this error "Error fsyncing/closing /dev/sdb1: Input/output error".

I have uploaded the Gparted error log at following link: http://pastebin.com/qMy0VE6a

I tried both Gparted & testdisk to recover data or partition but failed.

Please help to recover my data.

I installed latest version of Ntop-NG using following Repository: http://www.nmon.net/apt-stable/

by the following command in Ubuntu 14.04: apt-get install ntopng ntopng-data

Now i am unable to login into the WebUI using default admin/admin credentials. I tried adding new user using Redis also but it did not helped. No error is displayed but the page simply refreshes after clicking on Login button.

In CLi I see the follwoing line: "User changed to nobody"

Can this be the issue? Please help me to login into Ntop-ng.
