wireless visible, but will not connect

[Nemontemi]

I try, but a message shows saying: "This network requires encryption to be activated".

[Nemontemi]

I don't know where to change the router mode, could you specify?

[praseodym]

Type the router-IP in your browser while being connected by cable (because you are changing something). In you router interface you should be able to change the channel, the mode and the encryption.

In fact, it was set on "b+g+n" mode; i changed it to "b" alone. No wireless connection , yet.

EDIT: Today i was able to connect via wireless, by selecting on the router settigns the "no encryption" option, but now i have two concerns.

The first one is about my connection being stolen by my neighbours, the second one, which i'm going to check soon, is if i'm going to be able to connect to my school's wireless signal, since it requires encryption.

I hope you can help me fix this now; greetings.

I really do not want to bother, but i'm having problems again.

Yesterday, i was able to get a wireless connection, without encryption, but today, when i tried to do it, without having changed anythig, Wicd gets stuck while "Getting IP Adress".

I had to go back to my LAN connection, but i can't have this computer attached to my desktop; what do you think the problem may be?

Check again:

iwconfig
sudo iwlist scan
ifconfig -a
rfkill list

Check the BIOS settings ("last state", "on", or whatever)

Try WPA2-AES encryption if possible. Change it in the router interface, remove the wireless profile, and create a new one, do not edit the old one.

[Nemontemi]

EDIT: I've changed the type of encryption, but, again, no wireless connection.

P.S: Sorry about the delay, but i've been very busy at school.
