WiFi card compatible with XPS 15 9570
Thank you for your message. I’ll review the details and see if I can clarify the compatibility concerns. It seems there’s some uncertainty about CNVi support on the 9570 model. I’ll check available references and let you know what I find. Your situation sounds tricky, so I’ll keep an eye out for solutions while you consider your options. Appreciate your patience and the help from moriel5 and 5x5.
CNVi is a recent protocol Intel employs, needing CPU support. Models like 9560, 9461, 9462 and 9260 support it, while 2020 doesn’t. I suggested the AX200 over AX201 since the latter is more reliable on laptops. No worries if Dell offers a refund—review every detail before purchasing a new machine. You can even opt for the same model with different configurations or switch to a standard Qualcomm or Intel card. Other brands, especially budget ones, often struggle with Realtek: their audio and networking are decent but their drivers are poorly designed, unlike Killer’s better alternatives. By the way, what challenges do you face? Dell’s audio driver uses Waves MaxxAudio—consider using unofficial Realtek UAD drivers (official files exist) and ensure your monitor is properly calibrated.
I experience significantly faster performance on my S10 compared to both my laptops, even without a WiFi 6 access point. Linux also delivers better speeds than Windows 10, though it remains slower than the S10. It seems the Android drivers are more efficiently optimized.
Now that you point that out, it might be the cause. Still, my older gadgets—including my desktop over WiFi—perform better than a 3000 EUR Dell laptop, which is quite frustrating... I hope I qualify for a refund and return this device. In short, it's a great machine overall, but these small issues prevent it from meeting my needs.
Android drivers are often designed with poor efficiency. This might stem from compatibility issues with the router's chipset. Intel WiFi performs better on Linux than on Windows regardless. By the way, I understand how to set up a WiFi 6-enabled router (2 x 2x2 MultiMIMO, BT 5.0) for around $80. There are unbranded Mediatek MT7621 routers without built-in WiFi but with M.2 slots suitable for Intel AX200s.
It appears fewer retries occur during an iperf3 check, indicating better compatibility. The router uses an Atheros QCA4019 with OpenWRT, which may not be as efficient as the original firmware. Ath10K drivers typically offer superior performance compared to the closed-source alternatives.
