Very unstable internet

[MjmConway]

Hi, this is my first post,but this problem needs to be solved! I recently upgraded my PC from lubuntu to xubuntu. This is because I was fed up with basic features. Don't worry, my PC can handle xubuntu, it is working as fast as it did with lubuntu.

It keeps asking for my authentication key, then it will try to connect for 2 mins then it pops up again. Occasionaly, it says it connects, but then it disconnects 2 seconds later. This is UNBEARABLE.

Here are my wireless properties, I ran nm-tool

Title really needs to be about wireless connection, not internet.

Can you connect with a wire? Does this behave itself?

How far away are you from the router/access point ? Did you have good connection before on same machine with lubuntu?

When you say updated to xubuntu, do you mean fresh install or installed xubuntu-desktop? Which release ?
