On which chip to take usb wifi adapter?

Question

Iron

I'm looking for a whistle with an antenna for a desktop machine
. Mostly in my city, there are Chinese non-names
. And this tp link is tp-link tl-wn725n (as I understand it, it also cannot boast of stability or speed)
I noticed that the chips on them are either mtk or realtek
On which chip better to take in terms of stability?
And then I bought one on the MTK, the stability is not very different + noticeably the computer slows down
Who will tell you what?

Answer 1

Well, firstly, Wi-Fi eats a lot and the stability problem can be hidden in poor contact in the USB bus, especially in the power contacts, when transmitting, the current rises significantly, which can cause a decrease in voltage in the Wi-Fi adapter and its unstable operation. In tablets where they are soldered, there are rarely problems.
For more stability, I would recommend you a PCI-E card.
