Why this answer matters
AX5400 is an aggregate Wi-Fi class, not the speed of each Ethernet port or a guarantee of multi-gig internet throughput. Confusing those values can make a healthy Gigabit link look artificially 'slow.'

Requirements
What has to be true
- Expect a maximum 1Gbps link rate on the listed WAN/LAN Ethernet ports before protocol overhead and real-world limits.
- A multi-gig internet plan needs a router with a multi-gig WAN/LAN path to exceed Gigabit through that wired bottleneck.
Verify it yourself
Use this test sequence
Change one variable at a time so you know which requirement made the difference.
- 1
Check the router model label for RAX50.
- 2
Compare a wired client link speed with the router's Gigabit port specification.
- 3
Use DeviceOK network timing tests to diagnose stability separately from maximum throughput.
Limits
What this answer does not prove
- Wi-Fi client throughput depends on radio/channel/client conditions and is not equal to the AX5400 aggregate rating.
- Regional hardware revisions should be checked against the exact NETGEAR support page if the model label differs.
