Ethernet Couldnt Connect

[JustASchKid]

Hi i am currently doing a sch project using the Raspberry Pi 1 model B.
When i connect up the ethernet cable, there "new " lights came on but still no internet access when i went into the browser.
So i was wondering if there is a way for me to check if there is actually internet access like a program or a command.

Many thanks in advance

Connecting to the internet and connecting to the school's local area network are two different things. You have not said which is not working.

At a command prompt enter

Code: Select all

ifconfig

and report here what it returns.
Also

Code: Select all

ping 8.8.8.8

and

Code: Select all

ping google.com

Do enlighten me

Your RPi does not have an IP address for either the ethernet or wlan interfaces, so it cannot use any network connections.

Are you connecting to a home broadband internet router, or to a network at a place of work, school, college or university?

If it is one of the latter, contact the network administrators or IT help desk and ask for assistance - it is unlikely that anyone here will be able to help with the details of that specific network.

If it is a 'home' network connection the RPi should configure itself 'automagically' when it starts up. Are you sure that the ethernet cable is working and is plugged in at both ends? Has it been successfully used with some other device on the same network? Do other devices (like PCs or Macs) simply plug in and run?

Dear B.Goode,

yes i am connecting to school's network. i have contacted the smile helpdesk(aka IT helpdesk). she also had no idea how to help me. thats why i am asking on the forum for advise. i think i will just ask my supervisor when he is back from leave. Thanks for sharing your wisdom with me

Does your school network have MAC filtering?
Does your school network have a proxy?
Does your school network have a DHCP server or are all addresses assigned statically?

Ask your network admin on the helpdesk those questions and it may trigger her into understanding what she needs to do to allow your alien device to connect to her protected network.

When she asks "What's your MAC address?" the answer is "b8:27:eb:a1:6f:cf"
