@TP-Link 

Hi thanks for the reply.

So what's is going on.

I have fiber coming in to the house to a modem behind the TV. This is then connect to the master x20 ( living room ). 

I have a 2nd x20 in my gaming room ( gaming room)

Now all my phone's and laptops connect to the strongest x20 and the mesh is working fine.

Now my boy has a Xbox 360 in his room, when we find the wifi network when I select it it comes up with duplicate network and tells me to rename one off the points. 

I can put in the password but it will not connect to the x20. 

If I unplugge the 2nd x20 (gaming room ) so it's just the master ( living room ) it will start to work

By doing this it is making the 2nd x20 pointless.

I did try and talk to Vodafone about it but they just tould me what I know how to set it up. ( This happens on the app when setting up)

There solution was to send me a 3rd x20 , I tould them not too as I don't think it will make a difference as then I will have 3.

So it's only the Xbox 360 and other people must have had this problem??? 

Can I manually set up the Xbox some how to connect to the 2nd x20 by using the numbers

Thanks :-) 

Ok I had a chat with someone on the chat room and still not working.

We have tried

Changing the ssid to a new name 

Turning off fast roaming

Turning off the beamforming

Changed the password to a different encryption

Rest the deco x20 modem and Xbox 

Forgotten the network on Xbox and re found but still saying duplicate networks 

Soon as I unplugge the 2nd x20 and re load the Xbox it's ok.

Also if I reset the mesh with both turning back on the 1st time the Xbox will work.

We can not turn it off each time my boy wants to go on his Xbox . 

Is there away to just add the numbers for the IP gateway .....ECT

>Their [Vodafone] solution was to send me a 3rd x20 , I told them not to as I don't think it will make a difference as then I will have 3.

In your situation, if they offer 3rd x20 for free, I suggest you accept that offer. 

Place 3rd X20 side by side with Xbox 360, connect them by Ethernet cable and configure Xbox 360 use Ethernet connection.

This is workaround, but if nothing else works - that will.

@Alexandre. 

Good idea I will call them back up 

@Alexandre. 

Legend mate. I have got Vodafone too send me out a 3rd. I have just moved the 2nd one in too my boys room and hard wired the Xbox 360 in. And yes it's going at full speed wooooooop.

Boy is so happy and I will be later this week.

Still it's a strange one 

Thanks for you your help
