I have Pi 2 installed with raspberries OS

All the setting as default and its connected to WiFI, signal strength looks good. Here its :

enter image description here

However, I'm unable to ping Google. I have referred this ( Error on sudo apt-get update )

Still no help. Is there any minimum WIFI speed requirement there for PI 2 ? Also, is there any minimum Power supply requirement?

During update: I'm getting the messages as below and looks like it stopped :

err http://mirrordirector.respbian.org wheezy/non-free raanslation-en_GB something wicked happened resolving mirrordirector.respbian.org (-5 - no address associated with hostname)

6% [Connecting to mirroedirector.raspbian.org]

E: Some index files failed to download.They have been ignored or old ones used instead.

How can i access the website from its browser, also how to make an update and upgrade success? How to know if the board is really connected to internet or now?

Not only Google, Looks like unable to access any website- why? am I missing some configuration?

here is how sudoedit /etc/network/interfaces looks like:

auto lo
iface lo inet loopback

auto eth0
allow-hotplug ath0
iface eth0 inet manual

auto wlan0
allow-hotplug wlan0
iface wlan0 inet manual
wpa-conf /etc/wpa_supplicane/wpa_supplicant.conf
dns-nameservers 8.8.4.4 8.8.8.8

auto wlan1

allow-hotplug wlan1 iface wlan1 inet manual wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

MY lsmod gives this result:

cfg80211 386508 2 mac80211,rt2x00lib

the lsusb gives:

bus 001 device 004 : id 148f:5370 Ralink Technology,Corp RT5370 wireless 
adapter

the uname -r gives :

3.18.11-v7+

Note: I'm able to ping my SSID's IP address from the Board. However, I'm unable to ping my laptop from the board, even though it's on the same network.

Whats going wrong? Please help.

Maybe you have to add a dns server or something is wrong with the dns configuration. I have found an other question with the same error and a solution: Link. Mybe it'll work for you too.
Greetings

  • I was referring to this link : and, configure "dns-nameservers 8.8.4.4 8.8.8.8" [please refer my question]. What other DNS did you want me to add? and where should I add it? Any other suggestion, please? – AskMe Aug 7 '17 at 13:46

I noticed that in your /etc/network/interfaces file you have the line;

wpa-conf /etc/wpa_supplicane/wpa_supplicant.conf

There is a miss-spelling of supplicant in there. It should read

wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
