What It Is: The WiFi Card / WiFi Module (also called the WLAN Board) - the small circuit board that provides the printer's wireless network connectivity, separate from the main Formatter Board. A faulty WiFi card causes the printer to drop off the wireless network, fail to be discovered during wireless setup, or lose wireless printing entirely while USB/wired printing still works.

Why Buy From Max Printer Parts: We stock hard-to-find spare parts for HP, Canon, Epson and Brother ink-tank all-in-one printers, sourced and checked before they ship. Message us your exact model and part number before ordering and our team will confirm fitment.
Note: the source listing also named "HL-2080DW" (corrected here to HL-B2080DW, the actual current Brother model) and MFC-J430W/MFC-J615W - the latter are a much older (circa 2010-2011) legacy Brother inkjet line, generations before this WiFi module's other listed models, so we did not include them in the compatible-models list above. Brother does genuinely reuse WiFi modules across its laser and inktank lines from the same generation, so the ink-tank + contemporaneous laser models listed above are plausible, but please confirm exact fitment with us before ordering for any model not listed here.
