Dell M348H — Broadcom BCM4312 PCIe Mini Wi-Fi card at your door ₹149visit charge
Dell Mini 9 (910) or Vostro A90 not connecting to Wi-Fi?
The M348H is a Broadcom BCM4312 PCIe Mini Wi-Fi card (assembled by Arcadyne) — the original Dell service part for the Inspiron Mini 9 (Model 910) netbook and Vostro A90 shipped 2008-2010. After 14+ years the card often comes loose, the tiny antenna pigtails (the small wires connecting card to the laptop's built-in antennas) disconnect, or the BCM4312 chip stops working. We diagnose first (free with the visit), reseat and reconnect before replacing — the swap is rarely the first answer.

₹149 visit + on-site checkGenuine Dell-branded service part. The M348H is an 802.11b/g PCIe Express Mini Wi-Fi card — the small half-height card that slots under the Mini 9's keyboard panel. The radio chip is Broadcom's BCM4312 (a single-band 2.4GHz Wi-Fi controller); the card assembly was manufactured by Arcadyne for Dell. We carry remaining genuine service stock and OEM-grade replacements through our parts network.

The M348H was a shared service part across Dell's first netbook generation (2008-2010). Photograph the underside service tag and WhatsApp 7702503336 — we verify before our technician arrives.
The 8.9″ Atom-based netbook (Dell's first netbook). Shipped 2008-2009 with this exact M348H Wi-Fi card under the keyboard panel. Service tag begins with "PP39S" model code.
The Vostro-branded business variant of the Mini 9 (same chassis, same internal layout, same M348H card). Shipped 2009-2010 to small-business customers. Service tag begins with "PP39S".
The Ubuntu-preloaded variant of the Mini 9. Same internal hardware, same M348H Wi-Fi card. Driver compatibility differs (b43-fwcutter required on older Linux distros).
The M348H slot is a standard PCIe Mini half-height. Other Broadcom BCM4312-based cards from this era (Dell DW1395, HP/Compaq variants) are mechanically compatible but driver-binding may differ.
Later Mini-series netbooks (Mini 10, 10v, 1011, 1018) used different Wi-Fi cards (DW1397, Atheros AR9285). The M348H does not fit those chassis. Check your model number first.
The underside service tag shows your laptop's exact model and service-tag code. WhatsApp 7702503336 with a photo — we confirm M348H fitment in five minutes before the technician dispatches.
Most Mini 9 Wi-Fi problems trace back to a loose card, disconnected antenna, or driver issue — not a stopped chip. Free on-site diagnosis confirms which one before we charge for any part.
Wi-Fi on, no networks visible at all. Card came loose from PCIe Mini slot, antenna pigtails disconnected, or BCM4312 chip stopped working. Reseat first, replace if needed.
Card seated but loose; antenna cables loose. Each vibration breaks the connection. Reseat + reconnect fixes it permanently.
Antenna cables disconnected from card pins (the tiny black/white wires under the keyboard). Reconnecting both pigtails restores full signal.
Windows can't see the card at all. Card stopped responding to PCIe Mini bus — reseat first; replace M348H if reseat doesn't bring it back.
Hardware switch on but Wi-Fi greyed in system tray. Driver not loaded or card-ID mismatch (refurbished card from a different OEM). We supply the right M348H + driver.
M348H tops out at ~30Mbps. Want 802.11n / ac speeds? Intel 5100/5300 PCIe Mini upgrade card or USB dongle available — we discuss options on WhatsApp.

Repairing a 14-16 year-old Dell Mini 9 needs three things online sellers can't offer: real source for legacy Dell service parts, a technician who knows the chassis layout, and accountability if anything goes wrong.
We source genuine Dell service-part stock and OEM-grade Broadcom BCM4312 cards through our parts network — not generic clones with mismatched chip IDs that fail driver-load.
Most Mini 9 Wi-Fi issues are reseat-and-reconnect fixes, not card replacements. We try the cheap fix first — you only pay for a card when one is genuinely needed.
Every card we fit carries a 30-day replacement warranty. Local accountability, not online ship-and-forget.
Wi-Fi card replacement is a hardware-only service — we don't touch the SSD or OS install. Windows XP/7 or Ubuntu, files, programs stay exactly as they were.
You don’t carry a 16-year-old netbook across Hyderabad traffic. Engineer arrives at your office or home. ₹149 visit, waived if you proceed.
"No Wi-Fi" isn't always a card problem — sometimes it's just a loose antenna or a driver issue. We measure first, quote second, replace only with sign-off. No Fix, No Fee.
