09 — WiFi & Peripherals
ℹ️ HINWEIS
The BC-250 has no built-in WiFi or Bluetooth. You need a USB adapter.
WiFi Adapters
✅ Recommended
| Adapter | Chipset | WiFi | Bluetooth | Price | Notes |
|---|---|---|---|---|---|
| TP-Link Archer TX10UB Nano | MT7921AU | WiFi 6 (AX900) | BT 5.3 | ~$20 | Most consistently recommended. Works OOTB on Bazzite. Some BT disconnection reports on USB 3.0 ports — use USB 2.0 hub if issues arise. Separate WiFi + BT dongles recommended over combo units. |
| UGreen AX900 | MT7921AU | WiFi 6 (AX900) | BT 5.3 | ~$20 | Similar to TP-Link AX900. Community tested on Bazzite (Italian sub-thread). Random WiFi drops reported (10s, self-healing). |
| Fenvi FU-AX1800 | MediaTek | WiFi 6 (AX1800) | BT 5.0+ | ~$20 | "Works perfectly" on Bazzite. |
| EDUP AX3000M | MT7921AU | WiFi 6E (AX3000) | BT 5.0+ | ~$25 | Good Linux support, 6E band. |
| TP-Link Archer T2UB Nano | Realtek | WiFi 5 + BT 4.2 | BT 4.2 | ~$15 | Budget option. |
ℹ️ HINWEIS
Official elektricM recommendation: Realtek RTL8822BU chipset (in-kernel driver as of Linux 6.12+). Community testing favors MediaTek MT7921AU chipsets for best OOTB experience on Bazzite. If using a Realtek adapter that requires external drivers on Bazzite (immutable OS), prefer CachyOS or compile drivers via DKMS. Recommended driver repo for rtl88x2bu: cilynx/rtl88x2bu ↗.
Tip: WiFi/BT combo dongles often cause BT disconnections on USB 3.0 ports. Use separate dongles for WiFi and BT, or plug the BT dongle into a USB 2.0 hub (Italian sub-thread, verified with kernel 6.19+). This applies to all combo adapters.

⚠️ Budget / Limited Support
| Adapter | Verdict | Notes |
|---|---|---|
| TP-Link Archer AC1300 | Works with driver | Requires rtl88x2bu driver — manual install |
| TP-Link Archer TX35U Plus | Has issues | Requires rtw89 driver |
| Comfast / Brostrend AX1800 | Not recommended | Latency and disconnection problems |
ℹ️ HINWEIS
Note from elektricM: Some custom kernel builds (e.g., Bazzite "performance mode") may not include your WiFi adapter's driver. Choose adapters with in-kernel drivers (like RTL8822BU) for best compatibility. If WiFi stops working after a kernel change, connect via Ethernet and reinstall the driver.
Bluetooth Only (No WiFi)
If you already have Ethernet and just need Bluetooth:
| Adapter | Bluetooth | Price | ASIN | Notes |
|---|---|---|---|---|
| TP-Link UB500 Plus | BT 5.3 | ~$10–15 | B0DHJHMHFS | Tiny, long range, adjustable antenna |
| EDUP B3536 | BT 5.0 | ~$5 | Various | Dirt cheap from AliExpress |
ℹ️ HINWEIS
TP-Link UB600 (RTL8761BU) on Bazzite/atomic Fedora: Requires an out-of-tree
btusb rebuild to work on immutable Fedora-based systems. Fix maintained at SamSkjord/ubazzite600 ↗ (Jul 2026). "Works, but needs some dicking about."Storage — NVMe / SSDs
The BC-250 has a single M.2 2280 slot running at PCIe 2.0 x2 (~1 GB/s max) — also supports SATA III (~550 MB/s). Don't overspend — even cheap NVMe drives will saturate the bus.

✅ Tested & Working
| Model | Capacity | Price | Notes |
|---|---|---|---|
| Crucial P5 Plus | Any | ~$0.25/GB | Full ~1 GB/s on PCIe 2.0 x2 |
| Crucial P3 | 2 TB | ~$80 | Great value for bulk storage |
| Crucial P310 | 1 TB | ~$55 | Tested, reliable |
| Generic 1 TB NVMe | 1 TB | ~$50 | Cheap "Amazon" drives work fine |
| WD / Kioxia / PNY | 2 TB | ~$100 | Good value, tested |
| M.2 SATA drives | Various | Varies | Slot supports SATA III as well |
ℹ️ HINWEIS
Recommended: 512 GB minimum for OS + games. 1 TB+ if you install many titles. 2 TB for bulk storage on a budget.

Network — Ethernet
The BC-250 has a built-in Realtek RTL8111H Gigabit Ethernet port. Linux support is excellent — plug and play.
Source: elektricM specifications ↗
For faster networking or WiFi 6E, consider a USB 2.5 GbE adapter, though driver support on Linux can be hit-or-miss.
Keyboard & Input
The BC-250 ships without a power button header. Source: elektricM specifications ↗.
1. Solder to onboard button — two wires to the protruding button on the back of the board, move AUTO_PWRON1 jumper from pins 1-2 to 2-3
2. PSU latching switch — wire PS_ON to GND with a latching switch
3. USB keyboard for BIOS — any standard USB keyboard works
ℹ️ HINWEIS
If using a USB numpad or special keyboard, ensure it works during BIOS entry (some exotic layouts may not function correctly when spamming Delete).
