Can't access internet by wireless or cable


I have installed Mint 8 on my HP Presario lap top. When booted up using XP I can connect to the internet wirelessly with no problem. But, when I boot up with Mint 8 I receive a msg that there is no connection to the internet. I then tried by hooking up to the router with a cable and it still shows "not connected to the internet" msg. I tried rebooting while hooked up with the cable and same result. I read a lot on LQ.org and most of the info was way over my head, I'm an old newbie who wants to be free of windows. Thank you for any ideas>

I have no experience with Mint, but in other distribution like Fedora 11, network does not start automatically, you might need to find a way of setting the server to start network service at boot time. - Hope that leads you closer to the solution.

The first thing we need to do is see if your wireless card is detected and has a driver installed. Open a terminal and enter: "sudo iwconfig". If all devices say "no wireless extensions", then you need a driver.
To find out what the card is: "sudo lspci"

With the wired connection, you need to make some settings to match your local network setup. (Please tell us what that is.)

What server are you referring to? Regardless, I believe Mint DOES automatically start networking at boot time---in fact, the same is true for most Linux distros.

Can't access internet by wireless or cable.

Thanks pixellany for your help. I checked sudo iwconfig and received the reponse:
Lo no wireless extensions,
etho no wireless extensions,
wmaster0 no wireless extensions,
wLan IEEE 802.11bg ESSID:"" etc, etc.

When I search for sudo Ispci, I received the msg, "sudo Ispi" command not found"

I receive my Internet service via a Verizon wireless broadband device that I have installed in the usb port or a MBR1000 mobile broadband router.

no internet

your provider might be the problem or your receiver might not be picking up the right channel.
cable might be goosed, try it out with another pc.
very unusual for mint not to pick up a network, providing it has installed ok, check that DHCP is running and do not trust what icons report.

Fred.

It is "ls" for "list segments" and "pci" (LSPCI).
I also make typing or reading failures once a while.

All the best !

Thanks for pointing that out Karl! I ran lspci and received the following info:
03:00.0 Network Controller: Broadcom Corporation BCM4311 802.11b/g WLAN (rev 01).
But when I tried to run lspci-n I receive "command not found response" I guess I am supposed to be able to identify the chip set of my wireless card by running the lspci-n command. Any ideas.

Smile Can't access internet by wireless or cable

I am all set now. Thank you all so much for the time you each took to assist me. I have learned a lot from all of you. I am really excited to be a part of the Linux community. As it turned out my problem had nothing to do with Linux but in fact the cable I was using between my laptop and the server was defective. When I got that corrected Linux did its thing quickly and cleanly and downloaded the driver for my Broadcom4311 wireless card. This works beautifully! Thanks again so much for your patience. Best regards, Grateful burch
