So there are many companies offering WiFi chips: Intel, Mediatek, Qualcomm, Realtek etc… who makes the best ones?
I am sorry if this question sounds stupid, because in the tech world it’s best to compare the products themselves, not the brand. However I am not familiar with how this sector of the hardware industry works and product lines of each company. So I hope your answers can enlighten me and others in the same boat.
There’s so much more that goes into how good a wifi is even on board/system level than just who makes the wifi chip. Even within the same company it can wildly differ. It depends on the board design, layout, noise isolation, chipset drivers, antenna design, antenna placement, and manufacturing. If the wifi on your device sucks, there probably wasn’t enough engineers working on testing it when integrating into their system or good testing on the production line to catch defects. Sometimes something like a missing screw can mess with the radiation pattern. Source: RF test engineer.
