ADSL problem

Hi list

Just got my broadband live, and there's a bit of a problem
with it.
Basically, I have got all my settings right in the modem
interface,
and it is working fine in my windows partition.

But in Ubuntu, I boot up Firefox, try and load a webpage,
and...
nothing happens.

Can anyone give me any clues on what might be wrong?

Cheers

Is the link encrypted?  Do you need a License Registration
Server
process running?  Did you load the driver?

When you say 'Nothing Happens', do you mean that you just
see a blank
page and 'done', or it there a timeout on the dns lookup?

This is a BIG question - it took me three days to get my
mate's Linux to
work with WiFi.  Regrettably it isn't something that can be
easily
explained either.  This is one of the areas where Linux
isn't plug and
play, whereas Windows is.

Are you using a USB type modem? There are a few steps you
need to follow
to get these up and running. Check the forum and wiki.

Linux is not that tricky to get working with wifi, you just
need to
check that the hardware is supported.

No to the first one, it was bbc.co.uk. I am using a Linksys
ADSL2
modem, connected to my ethernet, if that helps for the othr
two.

Blank page. Status bar says 'Connecting to...' but nothing
happens. I
have left it for quite a while without it timing out.

To get the Windows side working, I had to ring the Pipex
help desk and
they gave me some DOS commands to run to clear out the
TCP/IP things,
I think they said. This got that side of things working.

Any ideas? Might ppoeconfig be required?

I presume this is connected via an ethernet cable to your
workstation
and isn't using wireless.

The first thing to do is check that your network card has
been detected. 

Run "ip link"

mojo-jojo david% ip link
1: lo: <LOOPBACK,UP,10000> mtu 16436 qdisc noqueue 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <BROADCAST,MULTICAST,UP,10000> mtu 1500 qdisc
pfifo_fast qlen 1000
    link/ether 00:a0:c9:92:9c:c0 brd ff:ff:ff:ff:ff:ff
3: sit0: <NOARP> mtu 1480 qdisc noop 
    link/sit 0.0.0.0 brd 0.0.0.0

You should see eth0. If this is the case, then your network
card was
detected correctly. The next thing to do is to check that
you have got
an IP address for that network device. You can do that by
running "ip
addr show dev eth0"

2: eth0: <BROADCAST,MULTICAST,UP,10000> mtu 1500 qdisc
pfifo_fast qlen 1000
    link/ether 00:a0:c9:92:9c:c0 brd ff:ff:ff:ff:ff:ff
    inet 10.187.182.233/27 brd 10.187.182.255 scope global
eth0
    inet6 2002:8b0:ed:2:2a0:c9ff:fe92:9cc0/64 scope global
dynamic 
       valid_lft 2591991sec preferred_lft 604791sec
    inet6 fe80::2a0:c9ff:fe92:9cc0/64 scope link 
       valid_lft forever preferred_lft forever

The line you're interested in here is the line that starts
inet. If you
don't or it starts 169.254 then you don't have an ip address
assigned.

You can either get this dynamically via something called
DHCP, or you
can configure it statically. We'll try dhcp first by running
"sudo
dhclient eth0"

mojo-jojo david% sudo dhclient eth0

DHCPACK from 10.187.182.226
bound to 10.187.182.233 -- renewal in 38436 seconds.

If you keep seeing DHCPDISCOVER lines over and over, then it
means your
router is not providing addresses via DHCP, although I find
this quite
unlikely.

If you repeat the "ip addr show eth0" line again
you should see that you
now have a new "inet" line.

Lets see if our networking is working. Let's ping the
machine that gave
us an IP address. If you take the IP address from the
DHCPOFFER line and
try to ping it using "ping <ipaddress>".
Press Ctrl-C to stop it.

mojo-jojo david% ping 10.187.182.226

If you get lines like this, then you have working IP
networking. I'll
let you work thought this email before we move onto dealing
with routing
and DNS.

Unlikely in this country I think.

The HantsLUG wiki [0] has a nice network diags page [1]
which might be
useful.

Cheers,

Cheers all. Am logging out of here and going into Ubuntu to
run
through David P's list of things. Back in a bit!

Think that's all ok on the network front. What should I
check next?

Thanks for all this help.

It looks like your router is at 192.168.1.1

Go there in a web browser, and see what the router console
says.

Hi Toby. Yep, that's right. Have already got the settings
sorted as
per Pipex's instructions. It's all working from Windows, so
I don't
think there is a problem there.
