Internet Problem

Well so far I'm still sick. I'm feeling little bit better. I have a free day today but out of the middle of no where my wireless modem lost or cant find the DSL single. I am able to connect to the modem but the DSL light blinks green then blinks red. I dont know what happen, I was just surfing the net and bam. Every time I try to go to a page a get this At&t Gateway problem. I says try rebooting the system which I have done from the computer many times and I've also gone to do it manually. I checked to make sure everything was set up right, even though it was working for the 1st half of the day and no one went near it. But still I unplugged the phone line and the power for 30 sec. I did this about 3 times with no luck. I really don't want to call my ISP because every time I do, they always tell me to do everything I've already done, and what I hate the most is when they do this it works! They must send some kind of message or something because they always tell me to do what I've already done, but it only works when they tell me to do it. Plus if that doesn't work then they will just send some moron over to tell me they cant find the problem. So now I'm stuck with a unstable linksys network. It works then doesn't work. I wonder if this post we even make it. Once again I'm posting when I'm half asleep but I did do I new How To for XP. It will help your CPU and RAM performance. It can be found here
