Network Configuration Reset & Bridge wlan1 to eth0

Question

So I want to connect to the Internet with my Raspberry Pi, but I can't. I am using SSH (ethernet) to give it commands but it just won't work. I have tried to bridge my wlan1 external adapter (TP-Link) from my neighbor's WiFi (have got permission to do that), bridge it to Ethernet so I can connect it to a router that will make the connection wireless on my house.

The problem is that I've read a bunch of tutorials but have messed up the network configurations a lot.

When I execute: ifconfig

This is what I get:

pi@raspberrypi:~ $ ifconfig
eth0      Link encap:Ethernet  HWaddr b8:27:eb:30:cc:67  
          inet addr:192.168.2.2  Bcast:192.168.2.255  Mask:255.255.255.0

          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000

          collisions:0 txqueuelen:1000 
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

I can't even connect to the Internet first, to do apt-get update etc. - how do I reset all my network configurations to default?

And after that, how do I get the wlan1 adapter to bridge the network over to Ethernet, so I can plug it into the router right away?

Thanks!

Sounds like it's time to start from scratch and pay attention to what you do next time. — Dmitry Grigoryev, Sep 26 '16 at 13:35

"The problem is that I've read a bunch of tutorials but have messed up the network configurations a lot" doesn't help tell what you ACTUALLY did.

Forget bridging, which is advanced configuration.

Try following the steps in How do I set up networking/WiFi/Static IP to setup your WiFi.

I just followed these steps, but my ifconfig output remained the same. I try ping google.com but no luck. I must've done: `echo "1" > /proc/sys/net/ipv4/ip_forward` and `iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE` which is what must have messed the wlan0 & wlan1 configuration. Is there any way I can reset that? @Milliways – Coto TheArcher Aug 27 '16 at 09:25

"these steps" is meaningless - if you are referring to my tutorial this describes at least 3 different approaches. If you want any help you need to post the contents of your config files (into your question NOT comments). – Milliways Aug 27 '16 at 10:07
