So I asked for help on the Linux Mint forums and its been 2 full days so im asking over here. I hope you guys can help me. If you do not know how to help please give me links. Thank you

Everything under this line is the original message.

So I do need to explain from the very beginning.

I have a Toshiba Satellite Laptop. It came pre-installed with windows 7 Home edition. That crashed and I ended up switching to Linux, as it happened I installed Ubuntu 10.10 at the time. Meanwhile I had fixed my windows and my laptop enjoyed a dual boot for about a year with wireless and Ethernet working perfectly for the longest time. Than my windows crashed again. I was forced to re-install, and with my warranty gone i was forced to buy Windows 7 Ultimate, and this is were the problem begins.

After installing windows 7 with a 100 GB partition and Ubuntu (now 11.10) with a 200 GB partition. I noticed that while my Linux networking working just fine my windows 7 networking would not work at all. Being and Intermediate computer user i used my Linux to find the drivers manually, pass them over to my windows partition and install them. I rebooted into window 7 and huzzah my Ethernet works, from there it was a quick connection to automatically install my wireless driver.

Here is were the peculiar thing happens. Now my Linux Operating systems networking will not work at all. I downgraded from Ubuntu 11.10 to 10.10. After that being futile and getting sick of path Ubuntu was taking I switched to Linux Mint. Still the same problem. Now here is were the trolling part comes in.

When i go to my college campus my wireless Internet works perfectly fine (Ethernet not tested). I come home and none work. Please help.

Here are the results to Sudo lshw -C networking

    If it works at college, and not at home, are you using the same connection and security level that was set up for school? Did you try redoing the wireless setup by scanning for the router in your home and setting up the password correctly so it connects to your home router?
    If it works at school, then, your wireless driver must be setup correctly, so, the fault must be with the way it connects to the home router. You might have done this already, but, if you didn't, make a new connection in your Network Manager for home, and reinput all the pertinent info again and see if that helps.

    Some of the Mods use Ubuntu, so, if you're patient, and, my answer didn't help, one of them might have more detailed instructions to help you.

    It might also help if you run ifconfig in the terminal and post the results here. It might contain some hints as to why you're having the problem.

    They were both automatic connections.

    Yes, multiple times including putting in all of the information manually.

    I moved off of ubuntu and am currently using LinuxMint12

    I'm wondering if Mint has your networking set up with both IPv4 and IPv6 and your home router is only set up for the IPv4 protocol. I've read forum thread where this has caused problems. Unfortunately, I'm not near a Mint install where I can check that out and tell you how to shut off the IPv6.
    In the Network Manager on my Fedora KDE netbook, when I go in to edit the Wireless connection, I see that IPv4 is set to DHCP and the IPv6 is disabled. See if your IPv6 is disabled and if not, disable it and see if that makes a difference. That's the first thing I would check.
  • I went in and saw that the setting was set for automatic. There was no disabled option, the closest option to that was ignore. I selected that option, saved, disconnected, than attempted to reconnect with no results.

    P.S.
    On a side note I forgot to thank you for being the first person in 5 days to reply
    Thank you for your Help.

    Your problem is quite strange, but that is that intrigues us.

    Since it is able to connect at school but not home I have to ask, when at home do you see any networks when you scan for active networks?
  • When i scan i can see my network as well as a couple other networks. I will attempt to connect, but it merely says wireless internet disconnected.

    Have you confirmed the encryption passphrase and encryption methods are being detected and saved correctly for your home network?
  • So I finally fixed it. I reset my router. I logged into linux. I was connected to the internet as if nothing had happend.

    Thank you all for your help.

    (it drove me nuts i even installed fedora to test it out.)

    That is a great thing. I guess your router's memory froze and wouldn't allow the new connection.

    You know, sometimes it's the simplest things, and, they're so simple that you forget. Twice in the past I've had my wifi stop working, and, because the Ethernet ports on the router were still working, I didn't think to reboot the router. Well, let's make this the third time, because, that should have been the first thing I should have suggested. Geez, forever a Noob. Glad you figured it out.
