Can't connetc to the OpenWrt ip address

i download the 19.07 x64 version from here and install on my laptop with 1 lan port.
i tried 2 methods to login the admin webpage but neither worked

method 1: connect the laptop to my router lan port, router wan port connct my modem, modify the laptop ipaddress to, which is my router's ip field. it doesn't work. ping the laptop ip address, no connection.

method 2: connect the laptop to my PC with wire, laptop ip set to, PC can't login modify the pc ip to, doesn't work

thanks for any replies

sounds like a case of unknown network driver...

you'll need to likely use image builder to "roll-in" the correct driver... what network-chipset / laptop-model is the laptop?

Thx for the reply
it's a lenovo Y510P laptop,
network chipset: Qualcomm Atheros AR8171/8175 PCIE Gigabit Ethernet Controller(NDIS 6.30)
