I tested out with U7 Pro Max (MLO enabled on EA firmware) and QC WiFi7 card and it topped out at about 800-900Mbps within the same room. Impressive for WiFi still, but reading the WiFi speed numbers on the box and expecting them to actually be achievable wasn't realistic for a decade now.
Idk why you say so. It doesn't take much searching to find receipts for people showing 3-4Gbps. But "realistic" is gonna be very hardware/firmware dependent, proximity to router, etc.
