I looked through lots and lots of threads trying to find the answer to my problem, but couldnt find any, so I'm hoping creating a new one will be OK.
I have the black xbox 360 slim with 250gb HDD and built-in wireless.
When I first started using my console last summer it connected without any issue at all. After that I did not change my router configuration at all, but I had a period where I didnt use my Xbox for quite some time.
After this period when I tried connecting to my router I kept getting an error when the console was at the first step - trying to connect to the router. It didnt give me an error code, it only said that it couldnt connect to my router and then gave me some suggestions for how to fix it.
I tried every single one of these, and I even tried the guide here on the website, going through every step until it redirected me to the forums.
The weird parts is this; my console will connect to my neighbors open wireless network, but I cant use that of course.
It will also connect to the secure network at my parents cabin with no problem what so ever.
It seems that the problem would be in my router, but I have tried every single step Microsoft has given me to try and fix it, from enabling HDCP, Mac Filtering, Static IP and all of the others. Today I even went as far as to convince the store I bought the router from to give me a new one, and I'm still having the same problem. Every computer, smart phone and other video game console I have connects without any problem.
