Assuming you signed up for internet service, then you should be contacting the technical support department of your internet provider.

i do have Internet but it didn't work on it. they said there was something wrong with my computer .  am try to see whats the easy way to fix it  ? i think its my PCI card ? how do i check that or ? what can i  try ?

they should walk you through the steps to get your computer work

what exacty did they say was "wrong" with your computer?

wired Ethernet network cards rarely go bad

my Internet provider said the couldn't get a default gate way or a ip address . so she uninsulated my internet network card and then installed it . then we had a default gateway and an ip address. so then we tried my Internet explorer and it didn't wanna go to the att home page. so then she told me there was something wrong with my computer and to call dell, but they were no help. do you have any advice? or something i could do to fix it. i akshully tried to use the terminal and i have a ip address and a default gateway, i tried to ping an Internet connection but i Guss i didn't know how to work.

If you can get an IP address and a gateway, then you should be able online.

Download Firefox on another computer, and install it. See whether you have better luck.

well have it on a flash drive and i downloaded it on to my computer, and it didn't work. so the Ethernet PCI card ant broken if i have an ip address and a default gateway ?  know what ?

 jokerforlifeny,

My suspicions are to try...

Powering off the ISP MOdem/router for 60 seconds. Also power off any wireless routers(if any). Power on the ISP modem/router. Wait 30 seconds, then power on the wireless router(if any)

Restart your computer and then try to connect. What happens? If you still cannot connect, then try restarting your computer and tap F8 and try to connect with safe mode with networking.

Was the operating system recently reinstalled?

I have no clue what you are doing.
