What to know before buying

Listing details to confirm

Listing details are inconsistent: title claims up to 1.2Gbps while the detail field gives 1167 megabits_per_second, and the upstream-rate entry says 3337 megabits_per_second. Coverage is listed as both 3800 square_feet and 353.03 square meters. The details also list RouterOS and WPA-PSK, which buyers should confirm for the selected model. Claimed coverage and performance depend on the home and network setup.

That distinction matters for this Wi-Fi 5 system: the claimed area and roaming design may suit a home needing broader coverage, but the feedback does not establish a particular speed or reliable results in every layout.
