system restore on ubuntu? or fixing wireless?
so...... my microsoft OS crashed. due to hard disks failing. i will be getting it fixed soon. but, i figured i would use ubuntu for the time being, well, when i got on, it no longer had the icon for wireless Internet. so i wast sure what was going on, i but i was looking for a system restore on my ubuntu to go back to a time where i had it. but could not find it, so i logged into on guest, and that got me internet but no icon for it on my profile. so how do i get it back, or is there possibly a system restore?
