I had similar problem with LinkHub HUB40 and Gentoo kernel 5.8.7-gentoo, wpa_supplicant 2.9 and "Intel Corporation Dual Band Wireless-AC 3168NGW (iwlwifi)". Authentication was ok, but association always timed out. Association with other routers was ok and it was working fine before with LinkHub too. I have "solved" my problem by changing Intel card (iwlwifi is horribly bugged anyway) to Ralink RT5372.
