Atheros installer for macOS Mojave and Catalina in LAN and Wireless 13,695 60 Posted December 4, 2019 On 12/2/2019 at 4:56 AM, ashcliffe said: The setup worked really well. Thank you. I got AR9285 working on Catalina. There is a small problem: the signal strength shows 1 dot at the bottom only. The laptop is less than a meeter away from the router and it looks odd. Any ideas? Hi, as far as I know the signal strength shouldn't be affected at all, the only thing that comes to mind is to make sure the antennas are connected correctly.
