Fangrui Product Details 5g2.4g 1200mbps Wifi Range Extender Wifi Repeater With 2 Ethernet Ports 1) Transmission Rate Up To 1200mbps 2) Four External Antennas Make The Relay Signal More Stable 3) Rj45 Network Port Supports Wired Access 4) Wps One-click Encryption Button 5) Two Working Modes Of Relayap 6) Simple And Friendly Operation Interface, Eliminating Tedious Configuration Relay Mode: Sometimes A Device May Be In The Living Room, But Due To Poor Signal, The Signal In The Bedroom May Only Be One Bar, Which Requires Further Expansion Of The Wireless Network. At This Time, You Can Consider Using A Second Wireless Router To Expand The Network Through Relay Mode. The Name Of The "amplified" Wireless Signal Is The Same As The Original Wireless Router Signal Name, Such As Mobile Phones, Tablets, Etc. There Is No Need To Manually Switch. Rely On The Network To Cover Itself. Features: Relay Setup Requires Connecting To Another Wifi Signal And Keeping The Wifi Name Settings Exactly The Same. Applicable Scenarios: Expand The Network And Achieve Signal "roaming" Within A Certain Range Ap Mode: Ap Mode Is Special. Generally, Only Ap Hotspot Devices Have This Function. At The Same Time, Ap Devices Do Not Have Bridge Or Routing Modes, But They Support Relay Functions. The Difference Between Relay And Ap Hotspot Is Also Very Simple. Relay Mode Actually Replicates A Wireless Network 1:1 And Does Not Require Cable Connection. Both Routers And Ap Devices Support This Mode; Ap Mode Uses Network Cables. It Expands Wifi Signals, But It Is Not Responsible For Managing The Network. It Is Equivalent To A Switch With Wireless Functions, Which Only Converts Wired Signals Into Wireless. Other Functions Need To Be Implemented By The Router (distributing Ip, Managing The Network, Etc.). Features: Convert To Wireless Network Through Network Cable, No Management Or Routing Functions. Applicable Scenarios: Covering Signal Dead Spots, The Function Is Similar To That Of A Relay, But The Ap Device Does Not Need To Be Configured,
