That may simply be the result of the way that mesh works -- a mesh
access point uses half its throughput to talk to the wireless device and
the other half to pass the messages back to the router.
Some mesh devices can use different channels for the two connections,
and this can improve performance, but each message still has to be
stored and forwarded so you won't get the same performance as direct
communication with the router.
It should be OK for streaming (e.g. to your TV and media player),
though. All the messages in streaming are going in the same direction
(assuming it's UDP and there's no handshake) and they'll arrive at the
same rate, just timeshifted by an imperceptible amount.

As others have said, that suggests that the Tenda box is acting as a
router rather than simply as an access point. If you can configure it
not to do that (I don't know Tenda kit) then you should get everything
to be able to talk to everything else.
When I set up the WiFi here, after we built an extension, the advice I
received (from this newsgroup and elsewhere) was that if possible I
should wire all the APs to the router rather than using mesh, and that I
should turn OFF the router's WiFi and rely on the APs throughout. I now
have good coverage throughout the house from three Ubiquiti APs cabled
directly (via a switch) to the router -- to be honest two would probably
have been enough. As we had builders and electricians in the house it
was easy to get Cat-6 cables put where we needed them, you may not have
that luxury.
Mesh is a compromise. It's a pretty good compromise, but if speed is
important you can't beat wires!
