Built-in motherboard performs slowly on 2.4GHz Wi-Fi
I recently assembled a new PC using an ASRock B560M Pro4/ac motherboard. I purchased it for built-in Wi-Fi, but after conducting some speed tests, the performance on my 2.4GHz network is significantly lower than expected—only around half of what it should be. The 5GHz band is delivering the expected 300Mbps without any problems, yet I’m only seeing a maximum of 45Mbps in my 2.4GHz connection. I have a 5-year-old PCIe X1 802.11a/b/g/n card that previously offered 100Mbps, and it’s a fresh Windows installation with all required drivers already installed.
It seems your old Wi-Fi adapter might actually perform better than newer ones, especially since many motherboard-included adapters are inconsistent. Switching to the 5GHz band could be beneficial because it generally offers higher speeds, reducing concerns about the slower 2.4GHz option.
It's due to the fact that your old card's 3x2 setup outperforms the 2x2 found on your motherboard. I usually opt for a 4x4 card, which performs exceptionally well—reliable at 1Gb over Wi-Fi. 1x1, 2x1 and 2x2 cards will consistently lag behind 3x2, 3x3, 4x3 and 4x4 options.
You could purchase a Wi-Fi extender along with an Ethernet cable and connect it to your PC. Just verify whether your internet connection uses a single band or dual band, as the extender won’t function properly if your Wi-Fi is dual band and you buy a single band model. I’m aware of this from my own experience using an extender.
I understand. It wasn't clear to me at first how the card worked with the motherboard. I hadn't looked up its specifications before purchasing it, which is perfectly fine.
