The other day there was some problem with BT and my landline and internet were off for the day and the following morning after when I went to check my email my internet is going extremely slow. Youtube videos only load 3 seconds then have to buffer when usually I don't have to buffer at all, even pictures are taking ages to load up.

I've heard there is something called bandwidth where if you download big files your internet goes slow can anyone clarify this with me because the previous week I had downloaded several large files (several gb each). How long does the slow internet last if this is the case?

Any other theories? By the way I use an AOL 8mb connection with a wireless router.
