What game are you playing that's not letting you online?
@ Ledis - this is the third Thread they've made asking this, I & others have already responded in one or other of them.
@ the OP - Please keep to one Thread, it not only helps us to help you more by keeping things in one place but posting multiple identical Threads is not only spamming it also does not mean you'll get an answer any faster, in fact it can have the opposite effect!
