zengxinhui / OpenWrt WR741ND-V2.config

Last active December 24, 2021 13:45

Flash a `FAST FW150R V2' router with OpenWrt firmware for TPLINK WR741ND-V2. The wireless hardware is probably corrupted and causes kernel to panic. Since I'm not able to find a way to disable ath9 from uboot/bootargs, I compile from source and remove ath9 support.
