At 2.4 GHz, it reaches 300 Mbps, while on the 5GHz band it blazes to 433 Mbps. The upgraded bandwidth has the higher capacity you need to increase Wi-Fi enjoyment at home.

verify data integrity and drive health. Dual WAN enables having two connections/ISPs
on one router, with load balance and failover mode for added stability
and redundancy to ensure uninterrupted internet access.
