Hello. I have the Cisco® Model DPC3939 DOCSIS 3.0 16x4 Wireless Residential Voice Gateway. Because it doesn't reach with great strength into the room where I have my original xbox 360, I have purchased an extender. I bought the NETGEAR WIFI Range Extender WN2000RPT. The signal strength is very strong now, but my xbox 360 will connect to the network but fails trying to connect to the internet. I've been at this for weeks now, and have not been able to get past this issue. Can anyone provide some help? Because my 360 did not come with wireless, I am using a wireless adapter that has always worked in the past and that seems to still be working since it finds my wireless network right away. Thank you!
