MacBook pro network problem!!

Question

My MacBook pro was working fine with my Internet at home and then out of nowhere it disconnected and now it won't connect and says alert: no Internet connection.... Is this a hardware problem or easily fixed??

Answer 1

POSSIBLE SOLUTION!  OK. I had this problem on my sister's macbook pro when I was beside her connected to my macbook!  The problem was the WAN network, but there is a simple solution, you might just have to play around with it.  Try the following. Just one will work. If you try the first and it doesn't work continue down the list.
1. Enter a dollar sign before you enter the password to the wifi network (i.e. $abcd1234)
2. Enter a zero-x before the password (i.e. 0xabcd1234   OR  0Xabcd1234) The x may be lower case or capital. 
3. Put the password in quotation marks (i.e. "abcd1234").
Hope this helps. I just spent 30 min on the phone with apple care (that she paid for!) and the guy told me there was nothing I could do but call my internet provider and have them change the WEP to WPA2. While this might not be a bad idea, it was not ideal and did not help with the online work she needed to do tonight for her job as it was after hours for my internet company. The guy from apple care who was surprisingly rude said it was just a know issue that macs had and nothing could be done. Funny how my daughter and I were both on the same network on our MACs! And have always used that network on our MACs! Sorry just had to vent but the above worked for me!
