Can Ccnnect to Network BUT NOT INTERNET???

Hi everyone,

i recently installed ubuntu 10.4 on my computer as a dual boot with windows 7...to start with i was struggling to connect wirelessly to my Bt home hub network.

After a bit of tinkering i manage to connect to the network by choosing to connect manually and entering:
IP: 192.168.1.50
SM: 255.255.255.0
Router: 192.168.1.254

But i still cant connect to the internet...i am connected to network fine but no internet?!?!f

Can anyone give me any idea to this problem? my ISP is BT if that helps? If you need any other information just ask and i will supply, been working on this for 2 week now so could seriously use some help.

Thanks ](*,)

Two weeks?? Why didn't you come see us? We have good news, I think we can save this patient! Please open a terminal and run and post:

Code:

---

ifconfig
ping -c3 192.168.1.254
ping -c3 74.125.115.147
ping -c3 www.google.com

---

As well, run and post the usual problem causer:

Code:

---

cat /etc/resolv.conf

Uh, oh, I bet you forgot DNS nameservers.

Thanks.

One of them is sumthin that your computer needs to work. Seriously, the internet works on numbers, not names. DNS nameservers are giant servers that will give you a number if you give it a name and then you can use that number to pull a web page. With no listing in /etc/resolv.conf, your computer says, "Google? I never heard of them:"

Code:

---

ping -c3 www.google.com
ping: unknown host www.google.com

---

When you tried Google's actual numeric IP address, there was success:

ping -c3 74.125.115.147
PING 74.125.115.147 (74.125.115.147) 56(84) bytes of data.

Your router probably has good nameservers stored in it. Let's use that for a nameserver. Please do:

Code:

---

sudo su
echo "nameserver 192.168.1.254" >> /etc/resolv.conf
exit

---

Now try:

Code:

---

ping -c3 www.google.com

---

Success? If so, open Firefox and try to get a web page. Success? If so, please use thread tools at the top and mark the problem SOLVED.

I hate to say it but that didnt work! NUTS!!

here is my input:

sudo su
<input password>
echo "nameserver 192.168.1.254" >> /etc/resolv.conf
ping -c3 www.google.com
ping: unkown host www.google.com

Also tried loading firefox obviously no improvement...what should i try next?

I retract that last post chili555 i retried the commands you sent me and it worked like a charm!!!!

My internet kept cutting in and out whilst typing commands so it must have cut out whilst i tried a ping without me noticing.

Jeez should have come on here sooner!

Thanks again!!!
