Troubleshooting Slow Wi-Fi Speed with Intel AC 8260 on Windows 11

Asked By TechWizard42 On

Hey folks! So I'm diving back into my computer after a long break (moved houses, started a new job, you know the drill), and I'm having some serious Wi-Fi speed issues. Here's the rundown:

1. My desktop is only getting around 50 Mbps on a restart with no apps running. My iPhone 12, sitting right next to it, is pulling 250 Mbps, so I'm really concerned about this 5x speed drop.

2. I've checked that I'm on the 5 GHz band, not the 2.4 GHz.

3. According to Task Manager, my connection type is 802.11ac, which should handle better speeds than what I'm experiencing.

4. The speed indicator in Wi-Fi settings flips between 60 and 90 Mbps, which adds to the confusion.

5. I made sure to install the latest drivers for the Intel wireless card from the official site. Here's the link just in case I got it wrong: [Intel drivers link](https://www.intel.com/content/www/us/en/download/777192/intel-wireless-wi-fi-drivers-for-intel-dual-band-wireless-ac-8260-and-intel-dual-band-wireless-ac-8265.html)

6. I've also updated Windows to the latest version and restarted multiple times.

7. Oddly enough, I can only select 'Auto' or '20 MHz Only' for the 5 GHz channel width, when I thought there would be more options available.

Honestly, I'm out of my depth here as this is normally pretty straightforward for me. Any tips or questions that could help? And here are my system specs:
- Windows 11 Pro version 24H2
- CPU: AMD Ryzen 5 3600
- GPU: AMD Radeon RX 5700 XT
- Motherboard: Asus Prime B450 Plus
- RAM: 32 GB
- Wireless Card: Intel(R) Dual Band Wireless-AC 8260

It might be worth switching your Wi-Fi settings to prefer 2.4 GHz and see if your speeds improve. Even if your phone is doing well on 5 GHz, your desktop Wi-Fi card might perform better on the 2.4 GHz band, especially if it's a bit far from the router. Try that out!

Just a heads-up, I've been reading that the 2.4 GHz band is typically limited to under 100 Mbps, so not sure if it's the best move for your setup, especially since your phone is getting much higher at the same spot.

That’s an interesting approach! I’m right in the middle of a restart, but I’ll definitely try this and let you all know how it goes. Thanks for the suggestion!
