Does re1 alone (without configuring lagg) work?
If yes, does it take long time to link up including DHCP? If so, possibly lagg0 is too early to be started up (sorry, not sure how lagg can be delayed).
And at the moment when I've configured lagg, wpa_supplicant was simpler (and I couldn't find no other reachable APs around me) than now and "WPA" was sufficient, but maybe it's insufficient now. I.e., fixed (preferred) SSID if you have multiple ones in your {/usr/local}/etc/wpa_supplicant.conf, regdomain, mode and so on.
If the slowness on negotiations with DHCP is the issue, and you can somehow configure DHCP server to supply fixed IP address for the specific MAC address, doing so and intentionally configure your PC to use fixed IP address and other configurations the DHCP server supplies could help.
