RAX120 1.0.1.118 on gigabit fiber getting max of 150mbps/500mbps on wifi 5ghz

I've read an extensive amount of older posts but haven't seen any particular comments on firmware 1.0.1.118. I recently purchased a RAX120 that I'm running directly off of CenturyLink gigabit service in Central Florida (no modem or PPoE needed). I get full gigabit speeds (940/940 or higher) on Speedtest built into the Nighthawk app but over wireless clients (e.g. MacBook Pro 13 TB, iPhone 11 Pro) I get a max of ~150mbps download and ~450mbps upload. I can't seem to get any faster of a download speed on wireless.

Traffic meter is off and the usual suspects checked. I realize that getting the full gigabit speeds on wireless (5ghz) is not going to happen, but is there anything I can do to get a faster download speed that is closer to the upload speed that I'm getting?

Thanks!
