Genuine Acer M.2 Wi-Fi adapter for listed laptops

This genuine Acer M.2 Wi-Fi adapter carries part number T77H348.02 HF and is built for the specific Acer laptop families listed in the compatibility data. It replaces a failed or missing wireless card in those models only. Buyers with other brands or unlisted Acer models cannot use this adapter.

Low-profile M.2 card draws minimal power

The compact M.2 form factor fits the designated slot without extra cabling and draws power directly from the motherboard. No fan or moving parts are present so operation is completely silent. Thermal output is negligible during normal wireless traffic. The card adds no measurable heat load to the laptop chassis.

Single card in the package

The box contains only the T77H348.02 HF adapter itself. No antennas, screws, driver media or installation software are bundled. The host laptop must already have compatible antenna leads and the operating system must supply or download the appropriate driver.

Questions about this item

How is the T77H348.02 HF M.2 card seated in an Aspire E1-571G, and what step is often missed?

Insert the card at an angle into the M.2 slot, then press it flat and secure it with the single retention screw; the step often missed is fastening that screw before reassembling the laptop.

What maintenance or replacement will the T77H348.02 HF adapter need over time?

The adapter itself has no user-serviceable parts; replacement is only required if the card fails or if the laptop is upgraded to a newer wireless standard.

What limit appears first when the T77H348.02 HF runs under sustained load in an M5-581T?

The primary limit is the thermal ceiling of the laptop's M.2 slot area, which can throttle the card before its own maximum throughput is reached.
