Technical difficulties

So Saturday I decided that it would be a good idea to enable the wireless feature on my dsl modem so I could connect our Wii to the internet. I got online and found the instructions on how to enable it. Unfortunately, the instructions were not correct. It told me to click on basic settings and from there to click on wireless. There were no options on basic settings other than save and reset. After a little bit of searching, I discovered the wireless feature in advanced settings (a little bit into going through advanced settings). I am not sure what I did, but doing that, I managed to lose my user name and password for my modem. And I can't find my paper that had it listed. So I broke down and called Qwest. After confirming that I was who I said I was, they gave me my user name and password. That fixed it. Briefly. Now where I can get on and read my email, that's about it. I can chat on aol, too. Jimmy was actually the one who discovered we could still get on aol and get our mail. Just can't get on any websites or on msn messenger. Only way I can get on any websites (such as this one) is to get on my computer in safe mode. I discovered this after spending a very, very long time on the phone on Monday with Qwest and HP trying to resolve the problem. The lady from HP has decided that we need to reload all of the software on the computer. I haven't called her back to do that yet because I needed to backup everything I didn't want to lose. That and the thought of spending more time on the phone trying to resolve this problem does not sound fun at all. Really does not sound fun at all. Really. I hate making phone calls to begin with. This just reinforces that distain. On the bright side...is there a bright side to this?
