Direct answer to the question

• BN59-01264B is a Samsung Wi‑Fi/Bluetooth module (Samsung calls it a “Network‑WLAN client”), board marking WCM730Q, used in many 2018‑era Samsung UHD/QLED TVs and some commercial/hospitality models. It provides the TV’s wireless LAN and Bluetooth (e.g., Smart Remote pairing). (samsungparts.com)
• Core tech: dual‑band 802.11a/b/g/n/ac Wi‑Fi plus Bluetooth 4.2; module family FCC ID A3LWCM730Q. (usermanual.wiki)
• Physical size (typical listing spec): about 78.3 × 29.3 × 7 mm. (applianceparts.com)

Detailed problem analysis

• Role in the TV
  • This board hosts the radio(s) that handle both Wi‑Fi networking and Bluetooth links. If Wi‑Fi disappears, drops frequently, or the Samsung Smart Remote refuses to pair over Bluetooth, this module (or its power/IO from the main board) is a common root cause. (ifixit.com)
  • The specific sub‑assembly WCM730Q integrates a Qualcomm combo chipset (QCA9379‑7) that supports 2.4/5 GHz 802.11ac and BT 4.2 with coexistence; Wi‑Fi is typically interfaced to the main board via SDIO and Bluetooth via UART. Practically, that means a single small board and connector provide both radios to the TV. (usermanual.wiki)
• Typical symptoms of failure
  • Wi‑Fi networks not found or cannot connect despite good router function.
  • Intermittent wireless throughput or periodic drops that persist after resets.
  • Bluetooth remote won’t pair (Power via IR may still work, but voice/buttons via BT do not). (ifixit.com)
• Compatibility overview (partial, verify by part number)
  • Frequently seen in 2018 NU and Q6/Q7/Q8/Q9 series (e.g., UN55NU8000FXZA, UN65NU8000FXZA, QN65Q7FNAFXZA, QN75Q6FNAFXZA) and several hospitality/digital‑signage models. Always match BN59‑01264B/WCM730Q on the original board rather than relying only on the TV model code because versions vary. (searspartsdirect.com)
• Mechanical/electrical notes
  • The module plugs into the main board via a ribbon or board‑edge connector and usually has one or more coax leads or printed antennas integrated into its plastic carrier. Ensure all RF connectors are firmly seated after service. (General practice for this module family.)
  • Power rails are supplied from the TV main board; if the module is not detected, verify that the WLAN/BT board receives its primary supply before condemning the module.
• Distinguishing from similarly numbered parts
  • BN59‑01264A/B are both listed by Samsung and distributors as “Network‑WLAN client” boards; do not confuse them with Samsung remote‑control part numbers that also start with BN59‑… The “B” revision you asked about is the WCM730Q board; many suppliers explicitly call it out. (applianceparts.com)

Current information and trends

• Availability/pricing in the US (recent listings vary widely due to part‑out market):
  • iFixit lists new OEM BN59‑01264B around $72.
  • ShopJimmy frequently stocks tested pulls ~mid‑$20s with model cross‑refs and notes to match the part number.
  • Other parts houses range roughly $30–$85 new; salvage listings on marketplaces can be under $20. (ifixit.com)
• Successor modules (e.g., BN59‑01359A/01360A, WCA731M) appear in later model years; they are not drop‑in replacements—always match your original board number. (shopjimmy.com)
• Radio platform details from regulatory filings confirm Qualcomm QCA9379‑7, dual‑band 11ac and BT 4.2, giving confidence in capabilities and typical performance envelope. (usermanual.wiki)

Supporting explanations and details

• Wireless specs relevant to troubleshooting
  • 802.11ac, 20/40/80 MHz channel widths, up to 867 Mb/s PHY in 2×2 operation; BT 4.2 with AFH and Wi‑Fi/BT coexistence. These specs explain why poor antenna connections or EMI near the TV can have an outsized effect on throughput and remote responsiveness. (usermanual.wiki)
• Physical characteristics
  • Common distributor spec lists the module at approximately 78.3 × 29.3 × 7 mm and identifies “WCM730Q” as the visible board code—useful for positive ID when the sticker is missing. (applianceparts.com)
• Example models carrying BN59‑01264B (non‑exhaustive)
  • UN49NU8000FXZA, UN55/65/75/82NU8000FXZA, QN55/65/75Q6FNAFXZA, QN65Q7FNAFXZA, QN55Q8FNBFXZA, plus several hospitality and signage SKUs such as HG50NT690UFXZA and LH55QMNEBGC/GO. Again, always match the part number on the original board. (shopjimmy.com)

Ethical and legal aspects

• Safety and ESD
  • Samsung’s own parts pages advise unplugging the TV and using protective gloves; in practice you should also observe ESD precautions to avoid latent RF/SoC damage. If the set is under warranty, opening the back cover may void coverage—consider authorized service. (samsungpartsusa.com)
• RF compliance
  • The module is an FCC‑certified radio subassembly (FCC ID A3LWCM730Q). Do not modify antennas or shielding; maintain the factory configuration to preserve compliance. (device.report)

Practical guidelines

• Before replacing the module
  • Power‑cycle the TV (unplug 60 seconds), update TV firmware, reset Network settings, and test Ethernet to isolate Wi‑Fi‑only faults.
  • If the Smart Remote won’t pair, attempt a BT re‑pair after a cold boot; if Power (IR) works but BT functions don’t, the WLAN/BT module path is suspect.
• Replacement checklist
  • Unplug AC, remove rear cover, locate the WLAN/BT board, disconnect cable(s), swap in a BN59‑01264B module labeled WCM730Q, reseat any antenna leads, reassemble, and retest Wi‑Fi and remote pairing. Follow antistatic handling. (samsungpartsusa.com)
• Post‑repair validation
  • Verify Wi‑Fi on both 2.4 and 5 GHz, stream a 4K HDR app to check sustained throughput, and re‑pair the Smart Remote via on‑screen prompt if needed.

Possible disclaimers or additional notes

• Regional/production variations exist; some TVs shipped with different WLAN module revisions within the same model family. An exact part‑number match (BN59‑01264B, WCM730Q) is the most reliable way to ensure compatibility. (shopjimmy.com)
• If the module has power/IO faults from the main board, replacing it will not resolve the issue; basic voltage checks may be required by a technician.

Suggestions for further research

• Provide your full TV model code and version (from the rear label, e.g., UN65NU8000FXZA‑FA01) and I can confirm compatibility against current parts databases and advise model‑specific disassembly steps. ShopJimmy’s compatibility tables and Samsung/retailer parts pages are useful references. (shopjimmy.com)

Brief summary

• BN59‑01264B (WCM730Q) is the Samsung Wi‑Fi/Bluetooth radio board used in many 2018‑generation Samsung TVs. If your TV has no Wi‑Fi or won’t pair the BT remote, this module is a common fix—just be sure to match the exact part number and follow safe service practices when replacing. (samsungparts.com)
