I got it to replace the old dlinkovsky 56mb s pci-card, and the signal picks up wonderfully - even behind the reinforced concrete wall that separates the router and the far corner of the room. Now, regarding the actual speed, while simultaneously answering your question on the drivers... Card version 3, operating system win 8, tariff speed 100 mb/s. When I connected the card to a USB port, Windows automatically recognized it and installed the appropriate driver. I typed in the network key, opened the browser, and discovered that the Internet was operational. The connection properties showed a speed of 300 megabits per second. I performed the speedtest, and the speed is quite slow—about 50 megabits per second. The connection speed is between 270 and 300 mb/s, but the speedtest has already given out 74 mb/s. I downloaded and installed the driver from TP link. I made the decision, "what if," and downloaded the driver from realtek (which was a slightly earlier version than the tp-link) - the connection speed is also 270-300mb / s, whereas the speedtest appears to be no more than 70mb / s. In most cases, I stayed with the driver that was provided by tp-link. Yes, by the way, the speed across the cable is an average of 95 megabits per second, but here the router can also cut because it's so ancient. In general, you are free to take a card, and if there were any issues, the previous revisions, number three, have already been completely fixed, and they fully function in win8 right out of the box. Feel free to do so.
