Ordering and delivery ran like Amazon Unsurprisingly easily and quickly from.
The establishment of the repeater was a little trickier than expected, but here the details of manual and web interface were very helpful, so the unit was more than 15 minutes after unpacking already in use.
The status LEDs are in operation, although very informative, but unfortunately also very bright. Especially when the repeater is to be connected as in my bedroom, actually too bright. Fortunately, the developers have however thought along with ASUS herein and provided in the web interface of the repeater, the ability to link the status lights on the night light function, so that the device is switched off at night light is also completely dark.
I have so far for lack of active speakers are not allowed to function - The AI player. But I had this in the purchasing decision even more as a nice little bonus on the plan.
All in all I am very satisfied with the performance of the repeater. The speed is high enough, and the connection reliable enough to power the TV easily with HD videos both from the local network as well as the Internet.
Bottom line, the RP-AC52 meets all expectations I had prior to a wireless repeater: Unobtrusive, stable, fast, and thanks to the support of 2.4 and 5GHz band also nice flexible and future-proof, and also a good complement to my wireless router that does not support itself 5G frequency band.
Only the night light function could give a slightly warmer, less sterile looking light, but that is already criticism on quite a high level.
Final Conclusion: Not quite inexpensive, but due to processing and performance MMN definitely worth the money.
