Before, as soon as I open my laptop, there is always an internet connection and I can already browse automatically. But now, every time I open my laptop, I still need to wait for about how many minutes for the internet to work. I mean, it's already connected and all and the signal quality is excellent. But i can't browse the internet for how many minutes. I still need to wait or renew the IP Address. What's wrong? If the trouble is the router, how can I fix it?
