The MSI B450I Wi-Fi performs very slowly.
Hello everyone! I was really trying to locate the perfect fix for my issue but kept missing it, so please forgive any oversight. I own an MSI B450i MB, which is decent. It works well with my R5 2600, stays cool, and has RGB headers—everything seems normal. I bought it because I couldn't route the modem to my room, so I needed built-in Wi-Fi. It functioned okay for a while, offering speeds around 200 Mbps (though my actual connection is 400 Mbps). With all the laptops and consoles connected, I thought it was fine.
However, I recently got a 2TB SATA M.2 drive to save space in my MITX case, and the performance dropped significantly—only about 50 Mbps under ideal conditions. That’s not great, especially since my Galaxy S10 and MacBook Pro reach 400 Mbps on Wi-Fi. My question is: Is this due to some strange PCI lane sharing (which shouldn’t happen since it’s a SATA drive) or is the adapter just faulty? Thanks for your help!
P.S.: I didn’t find any info in the BIOS about PCI speeds or sharing.
Based on my observations, it's more effective to purchase a Wi-Fi adapter instead of relying on built-in solutions. This approach ensures better performance and compatibility.
Avoids the point of getting an ITX board with onboard wireless. Plus this is an ITX board, which only has one PCIe slot- so if there's a gpu this isn't a viable option.
I believe swapping the Wi-Fi card might help, as it has its own dedicated port. I want to confirm whether this change would really improve performance before proceeding.
You might also consider a wireless bridge: https://www.amazon.com/TP-Link-Wireless-...65&sr=8-43 Basically, set up the device to join your current WiFi network and connect it through an Ethernet port. This shifts the workload away from your PCIe lanes and should perform similarly if not better than your previous configuration. I usually prefer Ethernet for my PC, but this could be a solid alternative if Ethernet isn't feasible.
