Eru's questions

I had been using Gnome on Ubuntu 16.04 instead of the usual Unity. When I updated to 18.04, this weird double u's logo persisted through the upgrade and now both of my home and lock screens are different.

Startup logo

Lock screen 1

Lock screen 2

sudo iw wlp2s0 link                                                             
[sudo] password for aadesh:

The above command shows connected but I'm not able to access any website other than my college's dc++ network.

Here's my wpa_supplicant.conf file :

ctrl_interface=/run/wpa_supplicant
update_config=1

network={
  ssid="RAM"
  scan_ssid=1
  key_mgmt=WPA-EAP
  identity="id"
  password="psk"
  eap=PEAP
  phase1="peaplabel=0"
  phase2="auth=MSCHAPV2"
}
