One of the offsite places I work at regularly has two open wifi routers (same name). macOS 10.14.5 keeps selecting the weakest signal (both on 2.4GHz, one on Ch1, other on Ch8) How do I force connection to a certain BSSID, airport prefs JoinMode=Strongest has no effect. airport -BSSID etc has been depreciated. Note I cannot make any changes to the wireless routers, so please no suggestions that I contact a sysadmin / IT person. Have googled but since the airport utility has been gimped by Apple, I can no longer use most of the suggestions from StackExchange.
