Thanks. I extracted rt2800lib.ko module from provided images, did disassembly via: ./staging_dir/toolchain-mipsel_24kc_gcc-7.3.0_musl/bin/mipsel-openwrt-linux-objdump \ -d -r --prefix-addresses ~/rt2800lib-BUILDn.ko > ~/BUILDn.dump.txt command and compered disassembled code.

The only difference is in some number rt2800_clear_beacon() function. Regards Stanislaw
