Cannot connect to wireless network

What Country/State/Province do you live in?

USA/Washington

Modem brand & model number: 

**** TG862G/CT

Router brand & model number: 

Same device as Modem.

If Wireless, are you using a white or black external adapter, or an internal (Xbox 360S) adapter?

Internal

Things you have tried: 

I've tried power cycling the router and the xbox. I've tried all of the security types my router has (open, WEP 64, WEP 128, WPA-AES, WPA-TKIP, WPA2-AES, WPA2-TKIP, and WPA/WPA2-TKIP/AES (this is the default) ) and the xbox failed to connect to all of the ones other than "open". It also works with a wired connection (I got the most recent update that way), but I can't have a wire running across my house safely so I want to get the wireless working.

Is UPnP Enabled? Yes/no/Unknown

Yes

Do you have a NAT error? If so, what is your NAT?

No

Any Error Codes you encounter: 

"Incorrect Wireless Password". I know the password is not incorrect because I use it with all of my other devices and it works.

Who is your ISP(Internet Service Provider)? 

Comcast Xfinity

Question Info


Last updated July 4, 2018 Views 2 Applies to:

There is an ongoing issue with the firmware of this device if its provided by Comast which flashes their own firmware. I recommend that you contact Comcast and have it placed in bridge mode and get your own router. Or have it replaced with a modem (or EMTA if you have Xfinity Voice Service).

Although the connection works over ethernet, that is an unacceptable solution. What is the Xbox or Arris doing wrong so that it cannot connect over the wireless? Is there a time estimate on a fix? The Arris is the default router being shipped by Comcast presently, so there are/will be MANY customers in the US experiencing this problem.

Hey there Jarrod!

The Xbox 360 Slim are not working properly with The Arris TG862G/CT in wireless mode. If you're not able to connect your Xbox with an Ethernet cable instead of the non working wireless connection, then you have to replace this specific model as your default gateway.

No, my router is not doing MAC address filtering. Also, if it was and I didn't know about it, "open" wireless would still have been blocked.
