Wifi setup

[mazhar897]

I am connecting to the pi using ethernet and vncserver using putty. I have made a static ip. My wifi is not working. The interfaces file is given below. What should I do/change?

auto lo
iface lo inet loopback

auto eth0
allow-hotplug eth0
iface eth0 inet static
address 192.168.1.60
netmask 255.255.255.0
gateway 192.168.1.1

auto wlan0
allow-hotplug wlan0
iface wlan0 inet manual
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

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

If you are using Raspbian Jessie then you set the static address in /etc/dhcpcd.conf

Add this at the end of that file:

Code: Select all

interface eth0
static ip_address=192.168.1.60/24
static routers=192.168.1.1

And undo the changes you made to /etc/network/interfaces

Code: Select all

iface eth0 inet static

should be

Code: Select all

iface eth0 inet manual

Thank you. I have made the changes. still not working for some reason. any idea why?
Besides, it says debian. Is that different from jessie?

[DirkS]

What is the output of

Code: Select all

cat /etc/os-release

It gives more details about the exact flavour of Debian

[mazhar897]

This is the output

PRETTY_NAME="Raspbian GNU/Linux 7 (wheezy)"
NAME="Raspbian GNU/Linux"
VERSION_ID="7"
VERSION="7 (wheezy)"

ID_LIKE=debian

[DirkS]

Ok. that seems to be OK.

Can you see your wifi dongle with

Code: Select all

lsusb

If you can, check the output of

Code: Select all

ifconfig

If it is working then you should see wlan0 listed.
Can you post the output of these two commands.

Your wifi connection has an IP address.
So what exactly is not working?

[mazhar897]

I try to connect it and browse the internet and it does not work

Try this in a LXTerminal command window:
ip route
ping -c3 $(ip route | awk '/default/ {print $3}')
ping -c3 8.8.8.8
ping -c3 www.google.ca
cat /etc/resolv.conf

Tell us the results from each command (or take another screen shot).

Your default route isn't set correctly. You've got two different subnets one for each interface and the default route appears to point to the wrong network.

Check what shows up on your laptop with an ipconfig command

Code: Select all

You're interested in the IPv4 default gateway address.

[DougieLawson]

That's odd because your RPi can't ping that gateway address.

Put /etc/network/interfaces and /etc/dhcpcd.conf back to the way they were when you first installed Raspbian.

[mazhar897]

Now the ip address is not static. How can I know the ip address?

[mazhar897]

I figured it out. It works now. Thank you everyone.
