The Internet connection of my house is very slow depending on the time zone because of the type shared by the whole apartment, and the problem related to NAT comes with it.
However, I want to refrain from wasteful expenses that seem not to be able to pull THE optical line of NTT independently.
So, I came up with a plan to connect to the company's LAN with wi-fi and use the company's Internet connection at home.
By the way, the position relationship between my home and my company is about 40 meters away and the height difference is about 25 meters.The window of the company can be seen from the balcony of the home once.
I tried the router at hand by the window of the company for the time being, but it was too unstable and useless.There is also a distance, but I think that there is also a reason that there are too many other wi-fi flying around.
Looking for a powerful wi-fi device in,
TP-Link Outdoor AP Machine Access Point 5G Dedicated 300Mbps CPE510 for Wireless LAN SMB
Is this a nice thing?It was found.By the way, 5G only means that the band of the radio wave to be used regardless of the 5th generation of the mobile phone is 5Ghz band (probably).
Or rather, I've ordered two while having some anxiety because I don't know how to use it specifically though it seems to be something.
And amazon reviews
First of all, there is a problem where there is a version of this product, which cannot be specified clearly at the time of order.
amazon.co.jp
It is not possible to use it in Japan in Ver2 perhaps when there is it from overseas.I think that ver3 is sent directly from domestic Amazon.
It is necessary to align the Ver3 one in two sets.
There was a comment to be worried about, but my order was shipped from "Denzaido old electric market" and both were v3.0.
By the way, it is such a feeling that it is inside.

I ordered two LAN cables at the same time.

Since it is connected with the pattern of "via the PoE adapter" in the figure above, two LAN cables were required per unit.
I tried to set the CPE510.
For the time being, connect one as shown above, and connect the 2 (LAN) cable to the existing LAN.
Since this device is a web-configured type with an initial IP address of 192.168.0.254, the PC used for the configuration must also belong to 192.168.0.0/24.

In my case, I made it 192.168.0.1.In addition, since the company's network is 192.168.100.0/24, we have also added 192.168.100.1 because we intend to change the IP address of the CPE to 192.168.100.0/24.
After changing the IP address of the PC to an address belonging to 192.168.0.0/24,
http://192.168.0.254/
, the login screen of the settings screen is displayed.
Initially, you can log in with User Name:admin, Password:admin, but you will immediately be prompted to change your password, so you need to change it to something appropriate.

I don't know, but I don't know, so I had an atmosphere that seemed to be good when I opened "QUICK SETUP"

Select "Access Point" to make the first access point

Changed the IP address to 192.168.100.251 for the company's network.

Change Security to WPA-PSK/WPA2-PSK and enter the appropriate PSK Password.I'm not sure, but I checked MAXtream.
This is almost the end of the first one.
Take it to another base where you want to connect the second one, and connect it to the LAN of the base in the same way as the first.
We recommend that you set up the first one to some extent to another base.
The PC used for configuration must also have an address that belongs to 192.168.0.0/24. Once connected again,
http://192.168.0.254/
Open <a0>.</a0>Log in and change your account just like the first one.

Now select Client.

In my case, I changed this to 192.168.100.252 to put it in the company's network.

Click Suarvey to

Since the list of access points in the neighborhood is displayed, check the first access point and click "Connect".

Then, put the PSK Password entered in the first unit in PSK Password.
This is almost the end of the second generation.All that's left is Next, Finish.
In this situation, I was able to open the first setting screen (in my case http://192.168.100.251/).
The orientation and position are adjusted while measuring the transfer speed between locations.
In my case, i pull out the WAN side of my home router and make it just a wi-fi switching hub, and use the DHCP of the company router to get the IP address again, or if i have a fixed IP address 192.168.100.0/24 Changed in.
I installed it as much as possible at the top of the window of the home for the time being, but there is too a difference in height for the distance, and the wall (concrete) of the balcony was installed in the position where it was not completely blocked and it was not possible to see through,

I am satisfied because a reasonable number came out in the measurement in Netfrix.If you get this much, you ^_^ can stream with a margin of 4k60p.
Until now, depending on the time of day, i didn't even watch in HD quality (;
By the way, the orientation was quite severe and was not connected or less than 10Mbpd depending on the direction.
The above measurement results also have not adjusted the orientation to severe much & shielding, I think that it is the one that has come out quite easily even though there is no prospect.
If there is a prospect and the direction is matched properly, the speed seems to go out considerably.
As a result, I was very satisfied, and it was a product that I could recommend very much depending on the environment.
I should have installed it earlier.
Thanks to this, the line has become faster, NAT settings are now free, VPN no longer needs to connect to the company, ExpressVPN can be canceled, I am glad that there are too many advantages such as being able to use the fax and NAS of the company from home (^^ a.
As an aside, ExpressVPN was a pretty good service with easy to use and short response time.
As an aside, the CPE510 I bought had a skill mark.
