I used speedtest and downloading things. at 1 oclock during nightime i get 380-400-450.. During daytime i get 40-80-120kbs

Internet speed tests are not very reliable. They measure the speed of the DSLAM, your ISP's throughput, their uplink, website loading speed etc. To measure the wireless speed of the access points, you should use a reliable measurement tool such as iperf running on two systems connected to the APs by wire. If it then turns out that the AP achieves a better throughput, you have isolated the bottleneck. Best indicator that the wireless link between your APs is not the bottleneck here are the varying results you see during night and day.

My speed non wireless speed is 40mpbs, download speeds are 35-40mpbs .

The wireless speed is 40 kbps to 120, to 200kbps and during 1 oclock in the morning 400 kbps, This is proven through months of testing with speedtests and downloads

I dont get what you mean by isolating the bottleneck, running a program doesnt tell me why my wireless speed is so riddicusly low.

The problem is clearly the link between those two, the other ap, the newer model gets the same speeds, it didnt use to be like this a year ago, Like i said during nighttime the speed is 4 times higher, what on earth causes this?

Doing professional speed test on the wifi link will reveal wether the bottleneck is the wifi link and it will tell about the actual speed possible on this wireless link. Speed tests over the Internet are no reliable way to measure wireless speeds, but the speed of the whole way from your laptop over the wireless link over the ISP's infrastructure over many routers on the backbone up to the website where the speed test is running. This makes the difference.

Typically variations between speed - especially over day and night - happens on the Internet all the time and in every country. That's why I doubt that it has anything to do with the speed of a wireless link.

I have been testing this for years, the internet speed is always high, the wireless speed is low and it has gotten lower the last year or so. I upgraded to vdsl, the speed is lower than 100kbps during daytime. But the speed down at the house that has internet connection with lines is 40mpbs, the problem is the wireless link. Whats causing this? This is riddiculus low..

Again: without measuring the speed of the different segments of your network, nobody can tell.

You have to measure the wireless speed of the WiFi gear and if it turns out that this is the bottleneck, you have to check the setup of the WiFi gear, the SNR, the link quality, the antenna alignment, cabling, channel allocation etc. etc.

Get iperf or iperf3 from https://iperf.fr/iperf-download.php. It's available for a plenty of OSes. Run the server instance (iperf3 -s) on a system connected by wire to the main AP. Start iperf3 client instance on a laptop connected by wire to the remote AP. You just need to tell the client instance on which system the iperf3 server is running. Results will be the max throughput of your wireless link. See https://iperf.fr/iperf-doc.php#3doc for some examples on how to do measurements (scroll down below the section explaining the various options).

Obtain a Satellite TV dish mount. It will allow you to tilt one unit up, and tilt the other unit down. Check with a Satellite TV dealer as they have a ton of them laying around.

i got CPE210 i connected it with the wa7210n, same problem, "unrecognized public network"

What is causing this? Could the router somehow block the aps? The old wa270g get 30kbps on a vdsl that gets 45mbps.

What should i do? I am tired of spending money on stuff that dont work.
