My Buying Guides on Realtek Rtl8821Ce 802.11Ac Pcie Adapter
When I decided to upgrade my desktop’s wireless capabilities, I chose the Realtek RTL8821CE 802.11ac PCIe adapter. Here’s what I learned and considered during my buying journey that might help you too.
Understanding What the Realtek RTL8821CE Is
The RTL8821CE is a PCI Express (PCIe) network adapter designed for desktop PCs. It supports the 802.11ac Wi-Fi standard, which means faster wireless speeds and better reliability compared to older standards. It also includes Bluetooth functionality, which is a nice bonus if you want to connect wireless peripherals.
Why I Chose a PCIe Adapter
Since my desktop didn’t have built-in Wi-Fi, I needed a reliable internal card. PCIe adapters like the RTL8821CE fit directly into the motherboard, offering a stable connection and better performance than USB adapters. If you want a clean setup without external dongles, this is the way to go.
Key Features I Looked For
- Wi-Fi Speed and Standards: The RTL8821CE supports 802.11ac, which can handle speeds up to 433 Mbps on the 5 GHz band. This was important to me for smooth streaming and gaming.
- Bluetooth 4.2 Support: Having Bluetooth built-in meant I could easily connect my wireless headphones and keyboard without extra adapters.
- Compatibility: I checked that my motherboard had an available PCIe slot and that my OS (Windows 10) had drivers available. Realtek usually provides good driver support.
- Antenna Design: This adapter often comes with external antennas, which help improve signal range and strength. I made sure the antennas were included and could be positioned for best reception.
Installation and Driver Setup
I found the installation straightforward. After seating the card in the PCIe slot and connecting the antennas, I installed the drivers from the Realtek website. Sometimes the motherboard manufacturer also offers customized drivers, so that’s worth checking. Having up-to-date drivers ensures the adapter performs at its best.
Things to Consider Before Buying
- Motherboard Compatibility: Confirm that your desktop has an available PCIe x1 or larger slot.
- Operating System Support: Verify drivers are available for your OS version. While Windows support is common, Linux support can vary.
- Use Case: If you need very high-speed Wi-Fi (like Wi-Fi 6), this adapter may not be the fastest option. But for most everyday tasks, it offers solid performance.
- Bluetooth Needs: If you don’t need Bluetooth, you might consider other Wi-Fi-only cards.
My Final Thoughts
The Realtek RTL8821CE PCIe adapter gave me a reliable wireless connection with decent speeds and added Bluetooth functionality. It was an affordable upgrade that worked well for my home office setup. If you want a simple internal Wi-Fi and Bluetooth solution and have a compatible desktop, this adapter is definitely worth considering.
I hope my experience helps you make an informed choice!
