Hi I currently have an Asus rt-ac66u router. I want to extend the signal strength and speed to some areas on the 2nd floor of my home where signal is ok but speeds die to around 1-2meg. I am looking for recommendation on access point to purchase that will fit my needs. I want to connect the new AP via Ethernet back to the Asus router I've noticed a lot of extenders that simply take the wireless signal and repeat it. I'd rather have something that will connect back via Ethernet for faster speeds. The extenders are half duplex right ? What access point do your recommend that has dual band 2.4 and 5ghz? I want to extend the existing SSID for both 2.4 and 5ghz so close clients can connict to the AP, any issues or conflicts doing this?
