Comcast offers no assistance with getting a Xbox connected to their hardware.  The cable modem also acts as router with wireless capabilities, so i don't normally need an external router.  When i tried a wired connection, I could connect to Xbox live, but the connection would only last a few minutes.  I came up with the idea to use my Linksys router.  So as of now, i have the router feeding off of the cable modem/router, and i am able to keep a stable connection to Xbox live wireless.  But i do not want to keep it this way. Can anyone provide assistance on how i can connect to xbox live using just the cable modem/router provided by Comcast? All other devices in the home (printers, smartphones, laptops, PC's) can connect to the cable modem/router with no problem

Here's what I'd try:-

Ensure your Arris wireless network broadcasts at 2.4Ghz (and not just 5Ghz is that is an option) as the internal adapter only talks at 2.4Ghz

Ensure the SSID (network name) is all one word, no spaces, no funny characters

Try turning off all wireless security / mac address lists on your router to see if you can connect with no security (just as a test)

If you can connect ok without security then that is progress, please let us know

If you cannot connect without security then you only chance is to find out if there is a firmware upgrade available for the Arris and hope it is fixed in firmware.
