Hi,
I want to make my WDR4300 Repeater,
I mean, I will connect the WDR4300 wireless to main router,
Then for this repeater I will connect 2 cameras in LAN.
How I do it ?
If you are going to just connect the two cameras to the WDR4300 using Ethernet cables and do not want to repeat the WiFi then you probably want to set the 4300 up as a Wireless Bridge or Media Bridge. Setting up the WDR4300 as a repeater will cut your WiFi speed in half.
If the native firmware of your 4300 doesn't have the option to set it up as a bridge then you will have to look at flashing the firmware to DD-WRT. You will have to CAREFULLY CHECK if there is a version for your router. Be careful when doing this as the slightest error in following the procedure will result in you bricking the WDR4300.
If DD-WRT is available and install it look at the DD-WRT Wiki and it will give you the step by step set up procedures for setting up a wireless bridge or if you choose a WiFi repeater if you choose to go that route.
