What to know before buying

Listing details to confirm

The listing is contradictory or inconsistent about port speeds: the title/highlights say 2 Gigabit PoE+ ports, the feature text calls them 2 Gbps PoE ports, and the detail table lists LAN bandwidth as 1000/100/10 Mbps. It also lists a 1200 megabits_per_second upstream rate while describing up to 1200 Mbps on 5 GHz plus 574 Mbps on 2.4 GHz. Check exact port speeds and wireless-rate interpretation before purchase. The listed 2,200 sq. ft. is a claimed coverage figure, not a guaranteed result.
