Up until a week ago I was able to connect my Macbook to my parents home wi-fi but cannot seem to any longer. Can you help? My mac was purchased towards the end of 2011 and runs on Lion. The modem/router is a 2wire Gateway through AT&T. Right at the time I stopped having access the 2wire went offline and had to be reset. Since that time, all other computers in the house are able to gain wi-fi access except my macbook. Strolling online I saw a post that suggested the problem may be caused by an inaccurate password XXXXX the keychain. In fact, there was an incorrect password XXXXX the keychain that I just now fixed but still cant get connected. The details of my attempts to login are as follows:
1. Open Network Diagnostics
2. Select the desired network ("Connecting..." takes forever, lights: wifi=green, wi-fi settings=green, Network settings=yellow, ISP=green, internet=red, server=red)
3. "Network Change Detected" box pops up (all lights turn red except wifi=green)
4. I click "ok"
5. I am prompted to provide the WEP Password, but it has been autoentered and shows as bullets- I hit "continue"
6. "Connecting..." takes forever
7. "Network Change Detected" box pops up (meanwhile the "Network Status" lights read: wi-fi=green, all other lights=red)
8. Box pops up "Unable to Join Wi-Fi Network...you may have entered an incorrect password XXXXX natwork name, chosen the wrong type of wireless security, or you may be out of range of the base station."
I did the same thing while manually entering the password XXXXX got the same result. I am sitting at the base station so I know I am not out of range.
Suggestions? Again, it works on my iPhone
and on all other computers in the house.
