Hi,
I'm afraid this should be an easy question, but I'm having trouble finding it in the documentation: can OpenWrt work in client mode (as described in https://openwrt.org/docs/guide-user/network/wifi/connect_client_wifi) but while not broadcasting its own wireless network? I believe I set up a DD-WRT device to do this years ago -- connect to my router wirelessly, and provide wired ethernet connections, but do not rebroadcast the wireless network at all (because the OpenWrt/DD-WRT device is much older and less secure than my main router and I don't want it diluting the wifi environment in any way) -- but I can't figure out how to do it with OpenWrt.
Thanks!
