In the connection properties (when connected via Wi-Fi) it shows me a speed of 65.0 Mb / s - so this is the maximum speed I can achieve without a cable?

No, this is the theoretical speed, taking into account interference or too low a signal level. It looks like you're working with a channel width of 20MHz, so the card in a clean environment should settle for 72Mbps. And it compiled at 64Mbps, so there is a small problem.

So it would be good to start diagnostics of the wifi network --> https://www.elektroda.pl/rtvforum/topic3158772.html
Preferably InSSIDer (Win), possibly Wifi Analyzer (Android).

One measurement DIRECTLY at the router
Subsequent measurements in typical places where mobiles are used.

And post the screen accordingly: https://obrazki.elektroda.pl/4257484200_1454694642.png / https://obrazki.elektroda.pl/9695492800_1454695020.png

ATTENTION : When using a laptop or smartphone, you need to orientate it spatially (rotate) at each measurement point so that you always have the maximum signal at the measurement point. This is very important, because by changing the orientation of the phone or laptop in relation to the direction of the router / AP, the differences in signal measurement can be VERY large.

Should I buy a different/newer card to get the maximum speed?

Yes, and it should be a 2.4/5GHz dual band card. But let's first see what's going on in the ether in your apartment.

There are different versions of InSSIDer, but what is most important is visible. Clinically pure ether on both bands, so no worries and it's good... ;)

I wonder why now the card is set up like this - try to move a few meters away from the router and check the connection speed again.

And secondly, if you have such a possibility, you can change the channel width in the router to 40MHz and see what happens - in a good setup and speeds could double.

And there is an extra - the card was set at 150Mbps, so at the max of what it can do. In such a clean environment and with high levels, you should get around 100...120Mbps on DL. This low connection setting of 20MHz is maybe a coincidence, or one of the devices has a problem - router or card.

With a new card, I would hold off until you know what router you will get with fiber - single or dual band and how much MIMO it will have. Then it will be easy to choose something so that you have 300Mbps over wifi (if the router allows it), and without overpaying.

For now, you can look around for a replacement for your current card compatible with your laptop. If not it's USB.

max that could be drawn with a 40MHz channel is about 220 ... 230Mbps.

Here you could easily achieve your 300Mbps and with a reserve for the unforeseen.

max that could be drawn in 802.11ac with the 80MHz channel and MIMO1x1 is about 310 ... 330Mbps.

max that could be drawn in 802.11ac with the 80MHz channel and MIMO2x2 is about 600 ... 650Mbps.

max that could be drawn in 802.11ac at 80MHz channel and MIMO3x3 is about 950Mbps.

max that could be drawn in 802.11ac with 80MHz channel and MIMO3x3 is about 1.Gbps.

As you can see, an ac1200 card (300+866/MIMO2x2) would be enough, unless you were thinking about some future and even faster connections. Possibly a low-cost card with MIMO1x1, but then you are "in touch" and any "flesh" can drop you below 300Mbps ;)

You probably won't get an internal card (replacement) with MIMO2x2, and you would have to have a second antenna in your laptop. I also don't know if the current antenna would go to 5GHz. You'd have to ask in the service department.

By the way, my current card is what type? Fast Ethernet or Gigabit Ethernet?

Fast Ethernet.

In Device Manager it even says FE --> Realtek PCIe FE Family Controller
