Couldn't connect to the internet via Airport, please help!

Someone please help me. I have a wireless connection at home, it's from next door actually. The router is 10 feet away from me. I've have never had a problem connecting. After installing boot camp on my MBP, the airport worked fine at first when I was at a friend's place. This was yesterday. Today, I tried connecting through windows and MAC OS X and none of them worked on my MBP. I just removed boot camp and formatted my mbp, but it still doesn't work. It's not a driver problem. When I boot, I get a message "no trusted connections .... connect to linksys?" When I say yes, it tries to connect but eventually fails. When I try it on the safari connection wizzard, it asks for a password, but I dont have a password on the connection. It's working fine on my macbook. The connection I was using yesterday had the same name "linksys" and requires a password, but I hope macs aren't that dumb.


Someone please help a desperate, sleepless newb to macs.

 

You have an unsecured network at home?
Anyway, there are several possibilities. Your MBP might be trying to connect to a different connection with the same or very similar name, and that network is secure, hence prompting the need for a password.
Another possibility is that you might have somehow configured a 802.1x connection using the same wireless network, so when your MBP tries to connect to the network it is doing it via the 802.1x configuration.
Open up your Internet Connect settings and make sure the 802.1x setting is not using your 'linksys' connection. You might also want to open up your Airport settings and double check the available networks.

 

I tried checking the available networks thing, linksys is there even when I re scan but it just won't connect. How do I change the 802.1x ??

 

None of that helped, how do i check if it's trying to enter a password?

 

Network Diagnostics was the closest thing to victory but it asks for a password, to join the network. There is no password.

 

You are the owner of the Linksys and haven't configured any of its settings have you? It sounds like it's requesting a password for your machine only. And do you know the type of password it's requesting? WPA-PSK or WEP?

 

Is this your router or someone else's?

 

The password it's asking for isn't a password, it's probably a WEP or WPA key. If it's someone else's router you are SOL.

 

It's my brother's router. It turns out that somehow I opened a VPN connection by mistake. Now that I deleted it and restarted, it's working fine. I just wish I figured this out before I uninstalled boot camp, merged the two partitioned, deleted every program that I didn't need, restarted the mbp, restarted again, reinstalled OSX, formated the laptop, installed OSX once again and fell asleep on the keyboard

Oh well, at least now it works I just have to remind myself that this isn't a PC and the usual protocol on a pc when something goes wrong won't work.
