So have an interesting question/problem for those interested:
Setup:DIR-655, 657 and possibly 857.
2.4Ghz only. 5Ghz doesn't reproduce this.
Reserved IP address for 1st gen 360.
MS Wireless 2.4/5Ghz USB adapter. Connected in front. Haven't tired back yet.
QoS rules set up as per XBL sticky.
NAT EndPoint.
Single Mode N Only.
WPA2 and AES Only.
Channel 11 (Manual)
Auto 20/40Mhz
Reserved IP address:Wired = Works
Wireless 2.4Ghz = Sees the SSID name and allows me to enter PW. Fails to connect and acquire the IP address. Times out and gets a self assigned IP address of 169.
Wireless 5ghz to my DGL-4500 in 5Ghz AP mode = Works and gets a IP address from the router and connects successfully to the XBL services.
DHCP IP address:Wired = Works.
Wireless 2.4Ghz = Works and gets a IP address from the router and connects successfully to the XBL services.
I also tested with a 3rd party 2.4Ghz AP set in bridge mode and it's LAN wire connected to the LAN port on the 360 and same thing happens if I use the Reserved IP address. If I change to DHCP, it works.
Is there a conflict some where or is this a configuration issue? I notice that one one occasions the MS adapter seem to connect as I was watching the Wireless status window on the router and there was a reserved IP address seen, however no IP address appeared on the xbox network settings. Most other times the connections were seen on the Wireless status window however the IP address was 0.0.0.0. Connected speeds were around 130 on the MS adapter and 200-300 using the 3rd party bridged AP.
I don't use WiFi for gaming however wanted to set gaming on WiFi on 2.4Ghz for some wireless testing. The times I have used WiFi for gaming it's always been on 5Ghz.
Anyone else see this or can offer up some info? Help?
