Overview & identity

17cb:1109 is the QCN9274 entry; 17cb:1107 is a different WCN7850 family. Hardware version checks further distinguish QCN9274 revisions.

Curated identifiers
pci 17cb:1109

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

In this source snapshot the device implementation builds as ath12k_wifi7 and uses the shared ath12k core. Older installed kernels may use different module names; trust the actual binding and module metadata.

  • ath12k_wifi7 — kernel driver/module candidate

Firmware

Host-loaded firmware required

The checked firmware directory or filename is family/revision specific. The complete requested files and board data must be read from the running system.

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

  • ath12k/QCN9274/hw1.0/*
  • ath12k/QCN9274/hw2.0/*

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 the selected PCI function

lspci -nnk -s BDF

Replace BDF with the address from your report. Compare Kernel driver in use with Kernel modules; only the former records binding. This ordinary query normally needs no root privileges.

Read firmware metadata

modinfo -F firmware MODULE

Replace MODULE with ath12k_wifi7 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

Neither the Wi-Fi 7 family name nor the ID entry verifies MLO operation, board firmware completeness or successful target boot. No minimum kernel release is asserted.

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