According to this page
https://openwrt.org/docs/techref/hardware/soc/soc.broadcom.bcm63xx the chipset which my router uses is supported (Broadcom 6318 ( 333 mhz ) + Atheros cpu ( 750 mhz ) + 256 MB ram)
Yet my device seems not supported on this page https://openwrt.org/toh/views/toh_fwdownload.
Do you think i can install openwrt on my router?
Thanks in advance.
