What makes you think that this message:

has anything to do with this:

The old wa270g get 30kbps on a vdsl that gets 45mbps.

and - again - how did you measure the 30kbps exactly? What has VDSL to do with WiFi speed?

I have set up a TL-WA7210 <-> CPE210 link and I get following throughput with default settings (WA7210 is AP, CPE210 is client, encryption is WPA2, rest is default).

First a quick'n'dirty built-in speed test of TL-WA7210 sending WiFi frames to the CPE210:






Looks good, full 150 Mbps 802.11n mode wireless speed, which equals around 100 Mbps data throughput, to be capped by the Fast-Ethernet interface of CPE/TL-WA for real data flow in later tests. That's best speed the TL-WA7210 can provide, but it's indoor and very short distance, so no wonder.

Next, a TCP/IP test with iperf on a laptop behind the CPE to a server behind the TL-WA7210:





That's real throughput for data, difference to the ~100 Mbit/s above is caused by replies for data sent, the additional WiFi frame layer and some loss in the TCP/IP layer. Next, speed on LAN interface of CPE210:





Matches real throughput measured with iperf. No surprise.

Now the throughput on the TL-WA7210 (actually, a different measurement, but mostly the same result):





Again, WIFi speed, some loss most certainly by replies to the client and possible retransmissions/collisions.

Now send your screenshots of actual WiFi throughput (not web "speed tests"), please. But make sure to saturate the 100 Mbit/s interface of the CPE210/TL-WA7210 during the test to avoid getting wrong results and drawing wrong conclusions from such tests.
