I have my raspberry pi running on raspbian jessie lite. I have created a hotspot on my windows machine and connected my raspberry pi to the hotspot. The pi has got an ip address assigned to it, but when I ping www.google.com I get unknown host, and when I ping 8.8.8.8 I get network is unreachable.

I tried connecting my phone to the wifi hotspot and it got connected to the internet. The hotspot shows that both my phone and raspberry pi is connected to the PC but the raspberrt pi is not connecting to the internet, while my phone is working fine.

  • As you have not told us how you configured the Pi any answer is speculative. The problem is more likely to be configuration of Windows.

  • @Milliways I used a opensource hotspot creator for windows. I checked and it was working fine with my mobile.

  • Ping following: <br> 1. gateway<br> 2. WAN interface of gateway <br> 3. gateway of gateway.<br> and tell us the result.

  • @Sean83 I'm not sure which is the gateway in my system(windows). I tired looking up all the device ip in my system. I'm not able to find out what my ip is. I tend to get ip under wireless lan adapter, ppp adapter, and ethernet adapter. My pc is connected to the isp through pppoe and the created hotspot shares this connection over wifi. Which one should I ping

  • @Sean83 If I'm right this is my gateway itallic_PING 192.168.0.1 (192.168.0.1) 56(84) bytes of data. 64 bytes from 192.168.0.1: icmp_seq=1 ttl=128 time=1.57 ms 64 bytes from 192.168.0.1: icmp_seq=2 ttl=128 time=1.25 ms 64 bytes from 192.168.0.1: icmp_seq=3 ttl=128 time=1.15 ms 64 bytes from 192.168.0.1: icmp_seq=4 ttl=128 time=1.14 ms ^X64 bytes from 192.168.0.1: icmp_seq=5 ttl=128 time=1.16 ms 64 bytes from 192.168.0.1: icmp_seq=6 ttl=128 time=1.19 ms 64 bytes from 192.168.0.1: icmp_seq=7 ttl=128 time=1.16 ms _italic

Reset to default

At minimum, you need to add a default gateway:

route add default gw <IP of gateway device>

The IP will be the IP address of the hotspot.

To resolve names to IP addresses, you'll need to add at least one DNS server:

echo "nameserver <IP of DNS server>" >> /etc/resolv.conf

The IP here will be that of your DNS server (quite possibly the same IP as the gateway above, but that's not certain as I don't know your network).

  • The default gateway and nameserver gets reset(deleted) after reboot. any workarounds?

  • Add dns-nameservers to /etc/network/interfaces, Ref. : wiki.debian.org/NetworkConfiguration
