MediaTek MT7601U USB family

A MediaTek USB radio using its own mt7601u driver, rather than the mt76x2 or mt7921 transport modules.

Overview & identity

The curated USB identity is 148f:7601. It is a checked family candidate and does not name a unique marketed adapter.

Curated identifiers
usb 148f:7601

A numeric match establishes a candidate family within the reviewed evidence. Marketing names, board variants, subsystem conditions and successful operation remain separate questions.

Driver & binding

mt7601u checks the USB identity and reads the ASIC revision. Its firmware loader tries a mediatek-prefixed path and a legacy unprefixed path.

Firmware

Host-loaded firmware required

Names are copied only as short source-backed identifiers. They are not an installation recipe; verify the exact host request and successful loading.

Checked examples or filename branches, not a complete installation list:

  • mediatek/mt7601u.bin
  • mt7601u.bin

Inspect firmware packaging on your distribution

Read-only diagnostics

Run one displayed command at a time. Replace uppercase placeholders with the affected device, interface or module from your own output. Commands are never executed here. Read-only output can still contain private identifiers.

Read USB interface binding

lsusb -t

Locate the port of this adapter in the USB tree. Driver identifies an interface binding; a vendor/device pair alone does not. Reading the tree normally needs no root privileges.

Read firmware metadata

modinfo -F firmware MODULE

Replace MODULE with mt7601u or the actual candidate module in your report. Metadata lists declared filenames; it does not prove a file was loaded. This query needs no root privileges.

Read existing Wi-Fi association

iw dev INTERFACE link

Replace INTERFACE with the wireless interface from iw dev. Association and rate are observations, not a throughput or firmware test. This query normally needs no root privileges.

Limitations & related issues

The two filenames are search alternatives, not two required blobs. A chipset family match cannot establish the RF quality of a particular USB dongle.

These guides are linked for relevant observations, not as known defects of every device in this family.
