the tp link is your router but what is your modem or your first device where the internet (cable ? ) comes into your house ?

Just a couple more links I found.

My advice would be if you need to do multiplayer that you send the router back. It does not work with XBOX.

I have tried UPNP, DMZ, and manually forwarding all the ports. Nothing works.

I did manage to get the DMZ to work for a few days and then it stopped.

To be fair to TP-LINK I don't think the problem is theirs I think it is the XBOX as the DMZ and port forwarding works with other servers and other services. By all means contact the TP-LINK support they are very helpful, and perhaps they can get Microsoft
to help

Thank you! This is valuable information.

[quote user="Ankau"]I got my friend to fill out his information too

Modem brand & model number: tp-link TD - 8840t

Router brand & model number: Linksys wrt1900ac[/quote]Can you ask your friend if their TP-Link TD-8840T is operating in bridge mode.

The TP-Link TD8840T is a combined xDSL modem with router/NAT built-in. So far so good, but since your friend also have an additional router/NAT (Linksys wrt1900ac) which terminates into an existing router/NAT (TP-Link TD-8840T), inbound/outbound traffic will
be NAT'd twice. Multiple levels of NAT in a home environment should be avoided.

Keep us posted!
