Need Help Connecting To Internet!!! (searched everywhere!)

[ZarazuaT]

Hello I am a newb to linux and for some reason i cannot connect to the internet. I have Ubuntu 10.04/Kernel 3.2.6 and have an Alfa AWUS036H wireless card. When i connect to a network (using Wicd network manager), it connects successfully, but when i go to a website it will not load at all. I have searched the forums and tried almost everything but i cannot get it to work! Any help is greatly appreciated. Thanks!

Hello and Welcome!
Look through this page, and post back with all requested information.
Also include the output of

cat /etc/resolv.conf

Use sudo for those commands if needed.

do this and read them.

man wvdial

man gnome-ppp

before doing this, make sure, you do,

apt-get install gnome-ppp && wvdial

that will do the job, also, read the wvdial man pages and there info files, you can do this by

info wvdial.conf

or

info wvdial

any of them should work, also, you need to set the dialer defaults by vi'ying or via using nano to the

nano /etc/wvdial.conf

this is basically the default configuration file, you can also, use the "alias" command to attach a new trigger on these commands, for bluetooth connection, do these

hciconfig -a

this will say if the bluetooth daemon is already running, if not, if says, "down" do this

hciconfig hci0 up

what this basically does is activates the bluetooth internal machine state to activated state.
Now, you need to read about rfcomm, and bind your devices, but before that you need to find the remote MAC of your remote device, to which you will be connecting, for that, you can,

hcitool scan

or use

sdptool

find your ways with the

--help

switches, and sure you will learn a lot, and then read the man pages, etc, after that, you can do this

rfcomm bind device_name channel_number

you get these info, such as the DUN channel from the options above on sdptool etc.
then, you need to set "pon" and "poff" entries, doing thsi will require some chatscripts to be set under the

/etc/peer/chatscripts/

directory and then set the rfcomm to the dialer defaults, that way you set it and do

pon the_file_name_yousaved_as_to_trigger_pon

and bingo, done cheers !

That's your wireless adapter. You have an IP address. And your /etc/resolv.conf shows your router and what I am assuming is a DNS server from your provider.
What error message do you get when you try to connect to Google or any other valid webpage? What browser are you using, and what version of the browser?
Are you able to ping Google by name, or by IP?

ping www.google.com
ping 74.125.131.147

Can you connect successfully via another wireless network, such as a public hotspot?
