I have 1 gig up and down fiber and decided to upgrade my mesh from an old Netgear Orbi AC3000 tri band I have used for years to the new TP Link XE75 Pro wifi 6e.  It works OK, but I am not getting wifi download speeds anywhere near 1 gig.  Usually in the 200-300 meg range even with my iPhone 14 pro next to the main Deco.  Maybe just a tad better than my old Orbi setup, but not worth the cost.  My ethernet wired desktop gets 980/970 so I know it isn't the connection.  I have tried everything I can think of and am about to return this to the store.  Any ideas?  I am running the latest firmware also.
