Gave up on this router as a whole house solution! The Xbox 360 slim will log in one day and work great, the next day it does not, tried every setting I could. B,G,N, channels, power settings. Everything in the house works great with this router but the stupid Xbox slim. Put the old WAP 54G back in and it works 24x7(Vintage 2002). Really no way to run hardwire to his toy without some major work.
He said when he can log into the high power router, it works great, but 90% of the time he logs in and it says he has internet connection but can't connect to the Live service. The Xbox slim supports 40Mhz channels and 300Mbps, if it can log in to the router. Even if you move the WAP54G router more then 15 feet away, it can't see it. Me thinks the WiFi built into the Xbox 360 slim was a 2nd thought and proabaly a 3 dollar chip and a paperclip for an antenna. He played on the high power router for like 3 hours with no lag Saturday, he came home from work Saturday night, no settings changed, he could not log in.
I even tried the ROCKU video box with this router in "N" mode, high def with no lags and a shared connection......
Done deal, router is in my office at the front of the house and still covers the whole property at 50% power.
Unless this Xbox slim will take a 3rd party adapter, I am done........ These Xboxes have been nothing but a WiFi nightmare from day one, for an Electronics Engineer, pity the average joe.....
