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.

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

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

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.

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

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

If using a USB numpad or special keyboard, ensure it works during BIOS entry (some exotic layouts may not function correctly when spamming Delete).
