Linux Mint Forums

Hi I'm a complete newbie in Linux OS. I installed Mint 7 on a XP computer with dualboot. My internet connection did not work at the begining. It "connected" but it did not gave me internet access. I used my Windows wireless configuration. And still it would not work, then meanwhile I was moving everything randomly it worked. The next time I turned my computer on it didn't work again, and also the next few times. Could anybody please tell me how to solve this?

bests,
Adrian

Try to connect to the network again then run the commands below for us and post the ouputs back here.

here is all the info directly from the terminal

Eh, the Intel Pro Wireless cards don't run the best on Linux. I'm sure there's a fix, but I'll have to look into that specific model a little more when I get off work. What's weird is that you don't appear to have an IP address, but can still ping your router. There was a guy with a similar issue around here on the forums, but he had a slightly different model. Post back the output from the commands below and I'll look more into it when I get home.

PD thanks for the help RedWagon

I looked around, but with most of the issues on that model the wireless won't even see networks or connect at all. Since you can see, connect, and ping your router I think your issue may not be anything with drivers, but something more basic. Run the code below & paste back. Also, power cycle your router (unplug it, wait a few seconds, and plug it back in) and if possible try to connect to a different wireless network and see if you get the same results.

Hi well one thing when I start to ping google and my router (192.168.1.1) mozilla and pidgin start working, do you know a way to automatize that process on startup? Anyways this is what appeard on the terminal:

You have no DNS server. When computers communicate over the Internet, or any network they use IP addresses instead of domain names. DNS servers are like giant phone books that look up the IP address from the domain name. This way, to go to a website you only have to remember the name, not a number like 53.255.54.83.
Unless your router is providing the DNS service (I highly doubt it) your computer can't take names like http://www.google.com and find the appropriate IP address. I did have you ping one of Googles IP addresses, but as a friend pointed out to me Google has many addresses and that one might not be reachable depending on where you live.

Hold on a sec.. did I read this right?

when I start to ping google and my router (192.168.1.1) mozilla and pidgin start working

Are you serious? Do you get replies from Google? And by Mozilla starts working you mean you can access websites? Was your output from your last post run before or after you pinged a few sites and stuff started working?

No in the terminal I did not got any reply from google. But after I made that i opened Mozilla and I could access all the websites. I first tried to ping google and my router, then I could surf on the internet. Also dis-enabling wireless and re enabling it makes the internet work. Pretty weird huh?
