Globe wifi connection problem

Hello,

We just bought a Globe wifi modem to have our own wifi connection. It worked great for the first week but after that, we cannot connect to the internet anymore. I did the steps everyday because my sister told me to but still, it doesnt work. But last week, for the whole week, I did the steps regularly and it started to work but right now, I have done these steps for 50 times I think but I cannot connect my pc to the net anymore.. That is why I loaded my globe Tattoo to ask this question and to find a solution for this internet connection problem. What am I supposed to do???
