    Question COMPLETE Newbie!! Never worked in Terminal b4. Wireless worked initially, now NOT

    Hi Everyone. Thank you in advance for taking the time to read my post. I have searched as much as I possibly could to make sure I do this posting correctly.

    I JUST installed Lubuntu 12.04 on an old Dell Inspiron 700M. I truly am a COMPLETE NEWBIE and have NEVER ran dos prompts, terminal commands, NOTHING like that ever before.

    I tried to look at the forum and copied and will paste as much info as I can find that might help to solve my issue. Like I said I am a COMPLETE NEWBIE (but want to learn) and have never done anything like this before. I am SURPRISED I ever got it running at all!!! lol I have my system setup to dual boot for either Windows XP or Lubuntu 12.04. I HAD a wireless connection for the first day, then JUST when I was getting really excited about how much FASTER Lubuntu was than running all the bloat of Windows XP (evidently), SUDDENLY ALL the wireless connections disappeared. Not only did I not get a wireless connection, there was system would no longer SEARCH for a wireless connection.

    I LOVED Lubuntu 12.04 when it was working and would LOVE to get it working again because it COMPLETELY revitalized this machine!! I am COMPLETELY LOST Now though. I have done as many searches as I can and have NO IDEA where to go from here. I dont really know the chipset or whatever wireless info is needed but I tried to follow the guidelines of the forum and post as much data as I Could from the commands I found on this site for wireless postings.

    Again I have NO IDEA what I DID...I just typed in the terminal some of the EXACT codes you suggested here on this forum.

    Btw the wireless connection DOES work in Windows, but not on Lubuntu. I really want my Lubuntu back and would LOVE to become much more proficient at Ubuntu in general. Baby steps I know, but I am ALREADY lost!!

    Below I will copy and paste the info I saved from the terminal in Lubuntu 12.04 in the instructions of this forum. I HOPE I am posting the correct data.

    Like I said it WORKED initially and just as I began to get really excited it suddenly stopped working. Btw the wired connection does work, but I never used wired and and it is not in a convenient area of the house.

    Thank you again in advance for any help you can provide.

    Here is the data I saved from terminal commands
