When you search question page, on every page there is at least one or two questions like: "My wifi is not working, please help!"
People just state there, that their wifi is not working, without showing ANY effort. There are literally hundreds of those topics, one little search on site would be enough, because those issues are covered greatly.
When they type their question title, it suggests them another topics already answered, often with steps applicable to their problem as well!
That doesn't apply to wifi issues only...
I must say that it's driving me mad :D, because I can't stand that laziness (and yes, I see there are already similar questions on meta.askubuntu)
EDIT: Pointing them to right direction (providing link), doesn't help in many cases. Am I authorized to down vote them (or make them at least try in the future somehow)? It can't be probably marked as Duplicate in many cases...because, for example notebook models can vary, even tough WIFI chipset is the same among wide variety of models.
I am always telling my self that they are newcomers, not to be hard on them - but that way,they won't change their attitude.
