Raspberry don't detect WiFi interface

[lbayo]

Hi,
I just installed a Raspberry PI 3 B + and I have installed NOOBs OS, latest version (September 2019). When booting it tells me that it has no WiFi interface. When I tried to setup WifI he says "No wireless interfaces found""
I have tried raspi-config and other programs but it never detects the WiFi interface.
It's not that I don't connect, it's that I don't even see the interface.
It is the first time that happens to me.
Should something special be done or is the Raspberry WiFi simply broken?

More information on the subject.
I bought two Raspberry Pi B + cards at Amazon. The cards are similar to oldest one but there are some appreciable differences, for example the 1GB memory chip of the old Raspberry is not observed now .
I have generated an SD with NOOBs, which works perfectly on an old Raspberry pi 3 B.
When loading with the new Raspberry, from the beginning, it is observed that they work much slower then with a old one.
Once the main desktop screen appears, it is impossible to set the WiFi: it does not recognize any WiFi interface ("No wireless interfaces found""). instead , it connects perfectly with ethernet interface
Any ideas ?

Your 2014 B+ doesn't have on-board WiFi.

Raspberry Pi Model B Plus Rev 1.2 does not have Wireless Chipset, therefore no Wireless

Thanks Guys,

That was my thoughts hence my request for information.

@OP you bought Model B's not 3B's and as stated it does not have WiFi.

Depending on the description you may have a claim for a refund but caveat emptor when purchasing on the internet.
