I had the same problem since the update for the xbox wireless N adapter, I use the wireless g adapter. The only thing that worked was for me was resetting my wireless settings on my xbox and in my router opening all the ports(if it has a gaming setting option) or the ones specified in the support page at XBOX.com in oneIP Address, also if your router supports NAT have it enabled. Then reset your network settings on your 360, scan for a network once you find yours, select it and change your 360's network settings from Automatic to Manual in the following 3 settings, the IP Address (enter the one you created with the ports open for the XBOX), Subnet Mask and Gateway, you can get those from your router settings. This worked for me and maybe it will for you. If you learn a different solution for the problem please let me know.

if you are an adult you should be able to validate your account with a credit card or after enough complaints MS suspend the account until they can prove is an adult who owns it and if parents should be able to create accounts for their kids restricting them from playing with adults.

FPS are no problem, but sport games that are one on one first thing they'll do is leave bad-rep and no shoot up the hole game, and if they are loosing is disconect to avoid loosing.

I'm tired of playing or having to deal with kids on XBL.  There should be an option to restrict the age group of the people we want to play on XBL.  I just want the option to choose the age group and not deal or play with kids and for those adults who have kids the option to restrict your kids from playing with or annoying other adults. What do you guys think?
