My wife and I were watching Netflix one night when suddenly our connection speed dropped to the point where netflix would no longer load. I have reset the wireless router several times, had Brighthouse reset the connection on their end, followed the standard "test xbox live connection" threads and all to no avail: the speed will not return, even though we are "connected" to xbox live. Also, the bars (full) are all white on the network, yet it still connects and I have not moved the xbox or router in over a year.
After running a "test connection" I got the following error codes : (even though it said it everything was connected)
w: 0000- 0021
X: 0000- F001
Y: 20A8- 48E0
ID: FFFF- FFFF
white external wireless adapter on the 360.
Road Runner Standard - Brighthouse
No issues with any other wireless device. Any ideas?
