Since you have multiple Xbox devices, I would switch two of them and see if the problem follows the box or the location. That would tell me where to concentrate my efforts. If your router allows you to change the bandwidth, you may want to try that as some devices like wide and others narrow. Move the Xbox around a bit but at about or longer distance as that may indicate that there interference with something else. That something else could be a non-WIFI device such as a cordless phone, weather station, ...

The Xbox One and 1 Xbox 360 are located in my living room as the AX3000, about 8 ft from it. They don't exhibit the same connection loss. They're are not on at the same time. Doing as you asked I did notice that when the Xbox One is in Standby mode (still connected to the network) it does interfere with the Xbox 360 in my living room. This was not an issue with my older router.

 

The Xbox 360 in my room does experience intermittent connection loss from Xbox Live, whether the Xbox One is in Standby mode or not. If i power cycle and reboot the router and my Xbox 360; I can watch Netflix for a good 4 hours with no problems. 

 

Both Xbox 360s connect to 2.4Ghz band due to it being better for distance. My other Xbox One is on the 5ghz band. The Xbox One supports the newer AC standard so it doesn't have problems connecting or maintaining a connection. The Xbox 360 is on the older Wireless N standard has the issue. I understand the router is compatible will all standards, but it doesn't work on older devices. At this point I'm not sure if I should replace the router with a non-intel SoC or use my old Belkin router as an AP just for this console. Thanks.

If having two Xbox systems, one has issues and the other does not I would focus on the Xbox.

 

You could swap the Xbox locations to see if it is a distance issue. If the issue follows the Xbox then you know it is something with the wireless card in the system. If the swapped Xbox now has connection issues I would look at either running an Ethernet cable or having another device grab the Wi-Fi like an extender and run an Ethernet cable from it to the Xbox.

Moving the Xbox 360 improved the connection. I still believe it's the router. My older router never dropped the connection. It just couldn't handle more than 10 devices. The network would slow down. 

 

Either way I am using a Linksys AE6400 Extender in my room. I am currently testing this set up. I will report if connection has improved. Thanks.

After using a Dual Band WiFi extender with an Ethernet connection, the Xbox 360 in my room is working. It doesn't loose connection. The Linksys RE6400 I'm using has a stable connection with the AX3000. 

 

I'm still not sure why the Xbox 360's wireless N connection drops. But I'll use this set up for now.

 

The Xbox 360 and Xbox One in my living room work fine. 

 

I hope the One Mesh firmware upgrade comes soon. I would prefer to buy tp-link extenders that can function as a Mesh system with my current router. Thanks

I've a similar issue. My Xbox 360 connected and worked fine with one active router. When I add a second deco device, Xbox gets an IP address of 169.* and doesn't connect to internet. Multiple restarts of Xbox, both deco routers didn't solve the problem. I disconnected the WiFi in Xbox settings and tried to reconnect. That is when Xbox threw a warning that multiple networks with same name exist and to name them uniquely. I turned off 1 deco device, the warning went away and Xbox connected to internet. I'm now turning off one deco device whenever I'm using Xbox 360.

I have that issue on my Xbox One when it's in Energy Saving mode or I happen to restart the system. It gets a 0.0.0.0 or 169.xxx.xxx.xxx IP and cannot connect when IP settings on the Xbox is set to Automatic. I have to disable the wireless connection and reconnect to the AX3000. That usually fixes the issue. The other fix, would be to assign a Static IP on the Xbox in order to connect to the router and switch back to Automatic. Since then I just leave my Xbox One in Standby Mode to avoid connectivity issues. The connection problem is from the router not being able to communicate with the devices....those are my workarounds. Still no new firmware on this AX3000.
